* @description | |
* | |
* This object provides a utility for producing rich Error messages within | |
* Angular. It can be called as follows: | |
* | |
* var exampleMinErr = minErr('example'); | |
* throw exampleMinErr('one', 'This {0} is {1}', foo, bar); | |
* | |
* The above creates an instance of minErr in the example namespace. The | |
* resulting error will have a namespaced error code of example.one. The | |
* resulting error will replace {0} with the value of foo, and {1} with the | |
* value of bar. The object is not restricted in the number of arguments it can | |
* take. | |
* | |
* If fewer arguments are specified than necessary for interpolation, the extra | |
* interpolation markers will be preserved in the final string. | |
* | |
* Since data will be parsed statically during a build step, some restrictions | |
* are applied with respect to how minErr instances are created and called. | |
* Instances should have names of the form namespaceMinErr for a minErr created | |
* using minErr('namespace') . Error codes, namespaces and template strings | |
* should all be static strings, not variables or general expressions. | |
* | |
* @param {string} module The namespace to use for the new minErr instance. | |
* @param {function} ErrorConstructor Custom error constructor to be instantiated when returning | |
* error from returned function, for cases when a particular type of error is useful. | |
* @returns {function(code:string, template:string, ...templateArgs): Error} minErr instance | |

* @element ANY | |
* @param {angular.Module} ngApp an optional application | |
* {@link angular.module module} name to load. | |
* @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be | |
* created in "strict-di" mode. This means that the application will fail to invoke functions which | |
* do not use explicit function annotation (and are thus unsuitable for minification), as described | |
* in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in | |
* tracking down the root of these bugs. | |
* | |
* @description | |
* | |
* Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive | |
* designates the **root element** of the application and is typically placed near the root element | |
* of the page - e.g. on the `<body>` or `<html>` tags. | |
* | |
* Only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp` | |
* found in the document will be used to define the root element to auto-bootstrap as an | |
* application. To run multiple applications in an HTML document you must manually bootstrap them using | |
* {@link angular.bootstrap} instead. AngularJS applications cannot be nested within each other. | |
* | |
* You can specify an **AngularJS module** to be used as the root module for the application. This | |
* module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It | |
* should contain the application code needed or have dependencies on other modules that will | |
* contain the code. See {@link angular.module} for more information. | |
* | |
* In the example below if the `ngApp` directive were not placed on the `html` element then the | |
* document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}` | |
* would not be resolved to `3`. | |
* | |
* `ngApp` is the easiest, and most common way to bootstrap an application. | |
* | |
<example module="ngAppDemo"> | |
<file name="index.html"> | |
<div ng-controller="ngAppDemoController"> | |
I can add: {{a}} + {{b}} = {{ a+b }} | |
</div> | |

angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) { | |
$scope.a = 1; | |
$scope.b = 2; | |
}); | |
</file> | |
</example> | |
* | |
* Using `ngStrictDi`, you would see something like this: | |
* | |
<example ng-app-included="true"> | |
<file name="index.html"> | |
<div ng-app="ngAppStrictDemo" ng-strict-di> | |
<div ng-controller="GoodController1"> | |
I can add: {{a}} + {{b}} = {{ a+b }} | |
<p>This renders because the controller does not fail to | |
instantiate, by using explicit annotation style (see | |
script.js for details) | |
</p> | |
</div> | |
<div ng-controller="GoodController2"> | |
Name: <input ng-model="name"><br /> | |
Hello, {{name}}! | |
<p>This renders because the controller does not fail to | |
instantiate, by using explicit annotation style | |
(see script.js for details) | |
</p> | |
</div> | |
<div ng-controller="BadController"> | |
I can add: {{a}} + {{b}} = {{ a+b }} | |
<p>The controller could not be instantiated, due to relying | |
on automatic function annotations (which are disabled in | |
strict mode). As such, the content of this section is not | |
interpolated, and there should be an error in your web console. | |

* @description | |
* | |
* The `angular.module` is a global place for creating, registering and retrieving Angular | |
* modules. | |
* All modules (angular core or 3rd party) that should be available to an application must be | |
* registered using this mechanism. | |
* | |
* When passed two or more arguments, a new module is created. If passed only one argument, an | |
* existing module (the name passed as the first argument to `module`) is retrieved. | |
* | |
* | |
* # Module | |
* | |
* A module is a collection of services, directives, controllers, filters, and configuration information. | |
* `angular.module` is used to configure the {@link auto.$injector $injector}. | |
* | |
* ```js | |
* // Create a new module | |
* var myModule = angular.module('myModule', []); | |
* | |
* // register a new service | |
* myModule.value('appName', 'MyCoolApp'); | |
* | |
* // configure existing services inside initialization blocks. | |
* myModule.config(['$locationProvider', function($locationProvider) { | |
* // Configure existing providers | |
* $locationProvider.hashPrefix('!'); | |
* }]); | |
* ``` | |
* | |
* Then you can create an injector and load your modules like this: | |
* | |
* ```js | |
* var injector = angular.injector(['ng', 'myModule']) | |
* ``` | |
* | |
* However it's more likely that you'll just use | |
* {@link ng.directive:ngApp ngApp} or | |
* {@link angular.bootstrap} to simplify this process for you. | |
* | |
* @param {!string} name The name of the module to create or retrieve. | |
* @param {!Array.<string>=} requires If specified then new module is being created. If | |
* unspecified then the module is being retrieved for further configuration. | |
* @param {Function=} configFn Optional configuration function for the module. Same as | |
* {@link angular.Module#config Module#config()}. | |
* @returns {module} new module with the {@link angular.Module} api. | |

* Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element. | |
* | |
* If jQuery is available, `angular.element` is an alias for the | |

* delegates to Angular's built-in subset of jQuery, called "jQuery lite" or "jqLite." | |
* | |
* <div class="alert alert-success">jqLite is a tiny, API-compatible subset of jQuery that allows | |
* Angular to manipulate the DOM in a cross-browser compatible way. **jqLite** implements only the most | |
* commonly needed functionality with the goal of having a very small footprint.</div> | |
* | |
* To use jQuery, simply load it before `DOMContentLoaded` event fired. | |
* | |
* <div class="alert">**Note:** all element references in Angular are always wrapped with jQuery or | |
* jqLite; they are never raw DOM references.</div> | |
* | |

* - [`addClass()`](http://api.jquery.com/addClass/) | |

* ## jQuery/jqLite Extras | |
* Angular also provides the following additional methods and events to both jQuery and jqLite: | |
* | |
* ### Events | |
* - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event | |
* on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM | |
* element before it is removed. | |
* | |
* ### Methods | |
* - `controller(name)` - retrieves the controller of the current element or its parent. By default | |
* retrieves controller associated with the `ngController` directive. If `name` is provided as | |
* camelCase directive name, then the controller for this directive will be retrieved (e.g. | |
* `'ngModel'`). | |
* - `injector()` - retrieves the injector of the current element or its parent. | |
* - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current | |
* element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to | |
* be enabled. | |
* - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the | |
* current element. This getter should be used only on elements that contain a directive which starts a new isolate | |
* scope. Calling `scope()` on this element always returns the original non-isolate scope. | |
* Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled. | |
* - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top | |
* parent element is reached. | |
* | |
* @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery. | |
* @returns {Object} jQuery object. | |

* @description | |
* | |
* `$injector` is used to retrieve object instances as defined by | |
* {@link auto.$provide provider}, instantiate types, invoke methods, | |
* and load modules. | |
* | |
* The following always holds true: | |
* | |
* ```js | |

* ``` | |
* | |
* # Injection Function Annotation | |
* | |
* JavaScript does not have annotations, and annotations are needed for dependency injection. The | |
* following are all valid ways of annotating function with injection arguments and are equivalent. | |
* | |
* ```js | |
* // inferred (only works if code not minified/obfuscated) | |
* $injector.invoke(function(serviceA){}); | |
* | |
* // annotated | |
* function explicit(serviceA) {}; | |
* explicit.$inject = ['serviceA']; | |
* $injector.invoke(explicit); | |
* | |
* // inline | |
* $injector.invoke(['serviceA', function(serviceA){}]); | |
* ``` | |
* | |
* ## Inference | |
* | |
* In JavaScript calling `toString()` on a function returns the function definition. The definition | |
* can then be parsed and the function arguments can be extracted. This method of discovering | |
* annotations is disallowed when the injector is in strict mode. | |
* *NOTE:* This does not work with minification, and obfuscation tools since these tools change the | |
* argument names. | |
* | |
* ## `$inject` Annotation | |
* By adding an `$inject` property onto a function the injection parameters can be specified. | |
* | |
* ## Inline | |
* As an array of injection names, where the last item in the array is the function to call. | |

/** | |
* @ngdoc method | |
* @name $injector#annotate | |
* | |
* @description | |
* Returns an array of service names which the function is requesting for injection. This API is | |
* used by the injector to determine which services need to be injected into the function when the | |
* function is invoked. There are three ways in which the function can be annotated with the needed | |
* dependencies. | |
* | |
* # Argument names | |
* | |
* The simplest form is to extract the dependencies from the arguments of the function. This is done | |
* by converting the function into a string using `toString()` method and extracting the argument | |
* names. | |
* ```js | |
* // Given | |
* function MyController($scope, $route) { | |
* // ... | |
* } | |
* | |
* // Then | |
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']); | |
* ``` | |
* | |
* You can disallow this method by using strict injection mode. | |
* | |
* This method does not work with code minification / obfuscation. For this reason the following | |
* annotation strategies are supported. | |
* | |
* # The `$inject` property | |
* | |
* If a function has an `$inject` property and its value is an array of strings, then the strings | |
* represent names of services to be injected into the function. | |
* ```js | |
* // Given | |
* var MyController = function(obfuscatedScope, obfuscatedRoute) { | |
* // ... | |
* } | |
* // Define function dependencies | |
* MyController['$inject'] = ['$scope', '$route']; | |
* | |
* // Then | |
* expect(injector.annotate(MyController)).toEqual(['$scope', '$route']); | |
* ``` | |
* | |
* # The array notation | |
* | |
* It is often desirable to inline Injected functions and that's when setting the `$inject` property | |
* is very inconvenient. In these situations using the array notation to specify the dependencies in | |
* a way that survives minification is a better choice: | |
* | |
* ```js | |
* // We wish to write this (not minification / obfuscation safe) | |
* injector.invoke(function($compile, $rootScope) { | |
* // ... | |
* }); | |
* | |
* // We are forced to write break inlining | |
* var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) { | |
* // ... | |
* }; | |
* tmpFn.$inject = ['$compile', '$rootScope']; | |
* injector.invoke(tmpFn); | |
* | |
* // To better support inline function the inline annotation is supported | |
* injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) { | |
* // ... | |
* }]); | |
* | |
* // Therefore | |
* expect(injector.annotate( | |
* ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}]) | |
* ).toEqual(['$compile', '$rootScope']); | |
* ``` | |
* | |
* @param {Function|Array.<string|Function>} fn Function for which dependent service names need to | |
* be retrieved as described above. | |
* | |
* @param {boolean=} [strictDi=false] Disallow argument name annotation inference. | |

/** | |

* @description | |
* | |
* The {@link auto.$provide $provide} service has a number of methods for registering components | |
* with the {@link auto.$injector $injector}. Many of these functions are also exposed on | |
* {@link angular.Module}. | |
* | |
* An Angular **service** is a singleton object created by a **service factory**. These **service | |
* factories** are functions which, in turn, are created by a **service provider**. | |
* The **service providers** are constructor functions. When instantiated they must contain a | |
* property called `$get`, which holds the **service factory** function. | |
* | |
* When you request a service, the {@link auto.$injector $injector} is responsible for finding the | |
* correct **service provider**, instantiating it and then calling its `$get` **service factory** | |
* function to get the instance of the **service**. | |
* | |
* Often services have no configuration options and there is no need to add methods to the service | |
* provider. The provider will be no more than a constructor function with a `$get` property. For | |
* these cases the {@link auto.$provide $provide} service has additional helper methods to register | |
* services without specifying a provider. | |
* | |
* * {@link auto.$provide#provider provider(provider)} - registers a **service provider** with the | |
* {@link auto.$injector $injector} | |
* * {@link auto.$provide#constant constant(obj)} - registers a value/object that can be accessed by | |
* providers and services. | |
* * {@link auto.$provide#value value(obj)} - registers a value/object that can only be accessed by | |
* services, not providers. | |
* * {@link auto.$provide#factory factory(fn)} - registers a service **factory function**, `fn`, | |
* that will be wrapped in a **service provider** object, whose `$get` property will contain the | |
* given factory function. | |
* * {@link auto.$provide#service service(class)} - registers a **constructor function**, `class` | |
* that will be wrapped in a **service provider** object, whose `$get` property will instantiate | |
* a new object using the given constructor function. | |
* | |
* See the individual methods for more information and examples. | |

/** | |
* @ngdoc method | |
* @name $provide#provider | |
* @description | |
* | |
* Register a **provider function** with the {@link auto.$injector $injector}. Provider functions | |
* are constructor functions, whose instances are responsible for "providing" a factory for a | |
* service. | |
* | |
* Service provider names start with the name of the service they provide followed by `Provider`. | |
* For example, the {@link ng.$log $log} service has a provider called | |
* {@link ng.$logProvider $logProvider}. | |
* | |
* Service provider objects can have additional methods which allow configuration of the provider | |
* and its service. Importantly, you can configure what kind of service is created by the `$get` | |
* method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a | |
* method {@link ng.$logProvider#debugEnabled debugEnabled} | |
* which lets you specify whether the {@link ng.$log $log} service will log debug messages to the | |
* console or not. | |
* | |
* @param {string} name The name of the instance. NOTE: the provider will be available under `name + | |
'Provider'` key. | |
* @param {(Object|function())} provider If the provider is: | |
* | |
* - `Object`: then it should have a `$get` method. The `$get` method will be invoked using | |
* {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created. | |
* - `Constructor`: a new instance of the provider will be created using | |
* {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`. | |
* | |
* @returns {Object} registered provider instance | |
* @example | |
* | |
* The following example shows how to create a simple event tracking service and register it using | |
* {@link auto.$provide#provider $provide.provider()}. | |
* | |
* ```js | |
* // Define the eventTracker provider | |
* function EventTrackerProvider() { | |
* var trackingUrl = '/track'; | |

* When called, it checks the current value of {@link ng.$location#hash $location.hash()} and | |
* scrolls to the related element, according to the rules specified in the | |
* [Html5 spec](http://dev.w3.org/html5/spec/Overview.html#the-indicated-part-of-the-document). | |
* | |
* It also watches the {@link ng.$location#hash $location.hash()} and automatically scrolls to | |
* match any anchor whenever it changes. This can be disabled by calling | |
* {@link ng.$anchorScrollProvider#disableAutoScrolling $anchorScrollProvider.disableAutoScrolling()}. | |
* | |
* Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a | |
* vertical scroll-offset (either fixed or dynamic). | |
* | |
* @property {(number|function|jqLite)} yOffset | |
* If set, specifies a vertical scroll-offset. This is often useful when there are fixed | |
* positioned elements at the top of the page, such as navbars, headers etc. | |
* | |
* `yOffset` can be specified in various ways: | |
* - **number**: A fixed number of pixels to be used as offset.<br /><br /> | |
* - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return | |
* a number representing the offset (in pixels).<br /><br /> | |
* - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from | |
* the top of the page to the element's bottom will be used as offset.<br /> | |
* **Note**: The element will be taken into account only as long as its `position` is set to | |
* `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust | |
* their height and/or positioning according to the viewport's size. | |
* | |
* <br /> | |
* <div class="alert alert-warning"> | |
* In order for `yOffset` to work properly, scrolling should take place on the document's root and | |

* **Note:** This document is an in-depth reference of all directive options. | |
* For a gentle introduction to directives with examples of common use cases, | |
* see the {@link guide/directive directive guide}. | |
* </div> | |
* | |
* ## Comprehensive Directive API | |
* | |
* There are many different options for a directive. | |
* | |
* The difference resides in the return value of the factory function. | |
* You can either return a "Directive Definition Object" (see below) that defines the directive properties, | |
* or just the `postLink` function (all other properties will have the default values). | |
* | |
* <div class="alert alert-success"> | |
* **Best Practice:** It's recommended to use the "directive definition object" form. | |
* </div> | |
* | |
* Here's an example directive declared with a Directive Definition Object: | |
* | |
* ```js | |
* var myModule = angular.module(...); | |
* | |
* myModule.directive('directiveName', function factory(injectables) { | |
* var directiveDefinitionObject = { | |
* priority: 0, | |
* template: '<div></div>', // or // function(tElement, tAttrs) { ... }, | |
* // or | |
* // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... }, | |
* transclude: false, | |
* restrict: 'A', | |
* templateNamespace: 'html', | |
* scope: false, | |
* controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... }, | |
* controllerAs: 'stringAlias', | |
* require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'], | |
* compile: function compile(tElement, tAttrs, transclude) { | |
* return { | |
* pre: function preLink(scope, iElement, iAttrs, controller) { ... }, | |
* post: function postLink(scope, iElement, iAttrs, controller) { ... } | |
* } | |
* // or | |
* // return function postLink( ... ) { ... } | |
* }, | |
* // or | |
* // link: { | |
* // pre: function preLink(scope, iElement, iAttrs, controller) { ... }, | |
* // post: function postLink(scope, iElement, iAttrs, controller) { ... } | |
* // } | |
* // or | |
* // link: function postLink( ... ) { ... } | |
* }; | |
* return directiveDefinitionObject; | |
* }); | |
* ``` | |
* | |
* <div class="alert alert-warning"> | |
* **Note:** Any unspecified options will use the default value. You can see the default values below. | |
* </div> | |
* | |
* Therefore the above can be simplified as: | |
* | |
* ```js | |
* var myModule = angular.module(...); | |
* | |
* myModule.directive('directiveName', function factory(injectables) { | |
* var directiveDefinitionObject = { | |
* link: function postLink(scope, iElement, iAttrs) { ... } | |
* }; | |
* return directiveDefinitionObject; | |
* // or | |
* // return function postLink(scope, iElement, iAttrs) { ... } | |
* }); | |
* ``` | |
* | |
* | |
* | |
* ### Directive Definition Object | |
* | |
* The directive definition object provides instructions to the {@link ng.$compile | |
* compiler}. The attributes are: | |
* | |
* #### `multiElement` | |
* When this property is set to true, the HTML compiler will collect DOM nodes between | |
* nodes with the attributes `directive-name-start` and `directive-name-end`, and group them | |
* together as the directive elements. It is recommended that this feature be used on directives | |
* which are not strictly behavioural (such as {@link ngClick}), and which | |
* do not manipulate or replace child nodes (such as {@link ngInclude}). | |
* | |
* #### `priority` | |
* When there are multiple directives defined on a single DOM element, sometimes it | |
* is necessary to specify the order in which the directives are applied. The `priority` is used | |
* to sort the directives before their `compile` functions get called. Priority is defined as a | |
* number. Directives with greater numerical `priority` are compiled first. Pre-link functions | |
* are also run in priority order, but post-link functions are run in reverse order. The order | |
* of directives with the same priority is undefined. The default priority is `0`. | |
* | |
* #### `terminal` | |
* If set to true then the current `priority` will be the last set of directives | |
* which will execute (any directives at the current priority will still execute | |
* as the order of execution on same `priority` is undefined). Note that expressions | |
* and other directives used in the directive's template will also be excluded from execution. | |
* | |
* #### `scope` | |
* **If set to `true`,** then a new scope will be created for this directive. If multiple directives on the | |
* same element request a new scope, only one new scope is created. The new scope rule does not | |
* apply for the root of the template since the root of the template always gets a new scope. | |
* | |
* **If set to `{}` (object hash),** then a new "isolate" scope is created. The 'isolate' scope differs from | |
* normal scope in that it does not prototypically inherit from the parent scope. This is useful | |
* when creating reusable components, which should not accidentally read or modify data in the | |
* parent scope. | |
* | |
* The 'isolate' scope takes an object hash which defines a set of local scope properties | |
* derived from the parent scope. These local properties are useful for aliasing values for | |
* templates. Locals definition is a hash of local scope property to its source: | |
* | |
* * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is | |
* always a string since DOM attributes are strings. If no `attr` name is specified then the | |
* attribute name is assumed to be the same as the local name. | |
* Given `<widget my-attr="hello {{name}}">` and widget definition | |
* of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect | |
* the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the | |
* `localName` property on the widget scope. The `name` is read from the parent scope (not | |
* component scope). | |
* | |
* * `=` or `=attr` - set up bi-directional binding between a local scope property and the | |
* parent scope property of name defined via the value of the `attr` attribute. If no `attr` | |
* name is specified then the attribute name is assumed to be the same as the local name. | |
* Given `<widget my-attr="parentModel">` and widget definition of | |
* `scope: { localModel:'=myAttr' }`, then widget scope property `localModel` will reflect the | |
* value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected | |
* in `localModel` and any changes in `localModel` will reflect in `parentModel`. If the parent | |
* scope property doesn't exist, it will throw a NON_ASSIGNABLE_MODEL_EXPRESSION exception. You | |
* can avoid this behavior using `=?` or `=?attr` in order to flag the property as optional. If | |
* you want to shallow watch for changes (i.e. $watchCollection instead of $watch) you can use | |
* `=*` or `=*attr` (`=*?` or `=*?attr` if the property is optional). | |
* | |
* * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. | |
* If no `attr` name is specified then the attribute name is assumed to be the same as the | |
* local name. Given `<widget my-attr="count = count + value">` and widget definition of | |
* `scope: { localFn:'&myAttr' }`, then isolate scope property `localFn` will point to | |
* a function wrapper for the `count = count + value` expression. Often it's desirable to | |
* pass data from the isolated scope via an expression to the parent scope, this can be | |
* done by passing a map of local variable names and values into the expression wrapper fn. | |
* For example, if the expression is `increment(amount)` then we can specify the amount value | |
* by calling the `localFn` as `localFn({amount: 22})`. | |
* | |
* | |
* #### `bindToController` | |
* When an isolate scope is used for a component (see above), and `controllerAs` is used, `bindToController: true` will | |
* allow a component to have its properties bound to the controller, rather than to scope. When the controller | |
* is instantiated, the initial values of the isolate scope bindings are already available. | |
* | |
* #### `controller` | |
* Controller constructor function. The controller is instantiated before the | |
* pre-linking phase and it is shared with other directives (see | |
* `require` attribute). This allows the directives to communicate with each other and augment | |
* each other's behavior. The controller is injectable (and supports bracket notation) with the following locals: | |
* | |
* * `$scope` - Current scope associated with the element | |
* * `$element` - Current element | |
* * `$attrs` - Current attributes object for the element | |
* * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope: | |
* `function([scope], cloneLinkingFn, futureParentElement)`. | |
* * `scope`: optional argument to override the scope. | |
* * `cloneLinkingFn`: optional argument to create clones of the original transcluded content. | |
* * `futureParentElement`: | |
* * defines the parent to which the `cloneLinkingFn` will add the cloned elements. | |
* * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`. | |
* * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements) | |
* and when the `cloneLinkinFn` is passed, | |
* as those elements need to created and cloned in a special way when they are defined outside their | |
* usual containers (e.g. like `<svg>`). | |
* * See also the `directive.templateNamespace` property. | |
* | |
* | |
* #### `require` | |
* Require another directive and inject its controller as the fourth argument to the linking function. The | |
* `require` takes a string name (or array of strings) of the directive(s) to pass in. If an array is used, the | |
* injected argument will be an array in corresponding order. If no such directive can be | |
* found, or if the directive does not have a controller, then an error is raised. The name can be prefixed with: | |
* | |
* * (no prefix) - Locate the required controller on the current element. Throw an error if not found. | |
* * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found. | |
* * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found. | |
* * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found. | |
* * `?^` - Attempt to locate the required controller by searching the element and its parents or pass | |
* `null` to the `link` fn if not found. | |
* * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass | |
* `null` to the `link` fn if not found. | |
* | |
* | |
* #### `controllerAs` | |
* Controller alias at the directive scope. An alias for the controller so it | |
* can be referenced at the directive template. The directive needs to define a scope for this | |
* configuration to be used. Useful in the case when directive is used as component. | |
* | |
* | |
* #### `restrict` | |
* String of subset of `EACM` which restricts the directive to a specific directive | |
* declaration style. If omitted, the defaults (elements and attributes) are used. | |
* | |
* * `E` - Element name (default): `<my-directive></my-directive>` | |
* * `A` - Attribute (default): `<div my-directive="exp"></div>` | |
* * `C` - Class: `<div class="my-directive: exp;"></div>` | |
* * `M` - Comment: `<!-- directive: my-directive exp -->` | |
* | |
* | |
* #### `templateNamespace` | |
* String representing the document type used by the markup in the template. | |
* AngularJS needs this information as those elements need to be created and cloned | |
* in a special way when they are defined outside their usual containers like `<svg>` and `<math>`. | |
* | |
* * `html` - All root nodes in the template are HTML. Root nodes may also be | |
* top-level elements such as `<svg>` or `<math>`. | |
* * `svg` - The root nodes in the template are SVG elements (excluding `<math>`). | |
* * `math` - The root nodes in the template are MathML elements (excluding `<svg>`). | |
* | |
* If no `templateNamespace` is specified, then the namespace is considered to be `html`. | |
* | |
* #### `template` | |
* HTML markup that may: | |
* * Replace the contents of the directive's element (default). | |
* * Replace the directive's element itself (if `replace` is true - DEPRECATED). | |
* * Wrap the contents of the directive's element (if `transclude` is true). | |
* | |
* Value may be: | |
* | |
* * A string. For example `<div red-on-hover>{{delete_str}}</div>`. | |
* * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile` | |
* function api below) and returns a string value. | |
* | |
* | |
* #### `templateUrl` | |
* This is similar to `template` but the template is loaded from the specified URL, asynchronously. | |
* | |
* Because template loading is asynchronous the compiler will suspend compilation of directives on that element | |
* for later when the template has been resolved. In the meantime it will continue to compile and link | |
* sibling and parent elements as though this element had not contained any directives. | |
* | |
* The compiler does not suspend the entire compilation to wait for templates to be loaded because this | |
* would result in the whole app "stalling" until all templates are loaded asynchronously - even in the | |
* case when only one deeply nested directive has `templateUrl`. | |
* | |
* Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache} | |
* | |
* You can specify `templateUrl` as a string representing the URL or as a function which takes two | |
* arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns | |
* a string value representing the url. In either case, the template URL is passed through {@link | |
* $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}. | |
* | |
* | |
* #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0) | |
* specify what the template should replace. Defaults to `false`. | |
* | |
* * `true` - the template will replace the directive's element. | |
* * `false` - the template will replace the contents of the directive's element. | |
* | |
* The replacement process migrates all of the attributes / classes from the old element to the new | |
* one. See the {@link guide/directive#template-expanding-directive | |
* Directives Guide} for an example. | |
* | |
* There are very few scenarios where element replacement is required for the application function, | |
* the main one being reusable custom components that are used within SVG contexts | |
* (because SVG doesn't work with custom elements in the DOM tree). | |
* | |
* #### `transclude` | |
* Extract the contents of the element where the directive appears and make it available to the directive. | |
* The contents are compiled and provided to the directive as a **transclusion function**. See the | |
* {@link $compile#transclusion Transclusion} section below. | |
* | |
* There are two kinds of transclusion depending upon whether you want to transclude just the contents of the | |
* directive's element or the entire element: | |
* | |
* * `true` - transclude the content (i.e. the child nodes) of the directive's element. | |
* * `'element'` - transclude the whole of the directive's element including any directives on this | |
* element that defined at a lower priority than this directive. When used, the `template` | |
* property is ignored. | |
* | |
* | |
* #### `compile` | |
* | |
* ```js | |
* function compile(tElement, tAttrs, transclude) { ... } | |
* ``` | |
* | |
* The compile function deals with transforming the template DOM. Since most directives do not do | |
* template transformation, it is not used often. The compile function takes the following arguments: | |
* | |
* * `tElement` - template element - The element where the directive has been declared. It is | |
* safe to do template transformation on the element and child elements only. | |
* | |
* * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared | |
* between all directive compile functions. | |
* | |
* * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)` | |
* | |
* <div class="alert alert-warning"> | |
* **Note:** The template instance and the link instance may be different objects if the template has | |
* been cloned. For this reason it is **not** safe to do anything other than DOM transformations that | |
* apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration | |
* should be done in a linking function rather than in a compile function. | |
* </div> | |
* <div class="alert alert-warning"> | |
* **Note:** The compile function cannot handle directives that recursively use themselves in their | |
* own templates or compile functions. Compiling these directives results in an infinite loop and a | |
* stack overflow errors. | |
* | |
* This can be avoided by manually using $compile in the postLink function to imperatively compile | |
* a directive's template instead of relying on automatic template compilation via `template` or | |
* `templateUrl` declaration or manual compilation inside the compile function. | |
* </div> | |
* | |
* <div class="alert alert-error"> | |
* **Note:** The `transclude` function that is passed to the compile function is deprecated, as it | |
* e.g. does not know about the right outer scope. Please use the transclude function that is passed | |
* to the link function instead. | |
* </div> | |
* A compile function can have a return value which can be either a function or an object. | |
* | |
* * returning a (post-link) function - is equivalent to registering the linking function via the | |
* `link` property of the config object when the compile function is empty. | |
* | |
* * returning an object with function(s) registered via `pre` and `post` properties - allows you to | |
* control when a linking function should be called during the linking phase. See info about | |
* pre-linking and post-linking functions below. | |
* | |
* | |
* #### `link` | |
* This property is used only if the `compile` property is not defined. | |
* | |
* ```js | |
* function link(scope, iElement, iAttrs, controller, transcludeFn) { ... } | |
* ``` | |
* | |
* The link function is responsible for registering DOM listeners as well as updating the DOM. It is | |
* executed after the template has been cloned. This is where most of the directive logic will be | |
* put. | |
* | |
* * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the | |
* directive for registering {@link ng.$rootScope.Scope#$watch watches}. | |
* | |
* * `iElement` - instance element - The element where the directive is to be used. It is safe to | |
* manipulate the children of the element only in `postLink` function since the children have | |
* already been linked. | |
* | |
* * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared | |
* between all directive linking functions. | |
* | |
* * `controller` - a controller instance - A controller instance if at least one directive on the | |
* element defines a controller. The controller is shared among all the directives, which allows | |
* the directives to use the controllers as a communication channel. | |
* | |
* * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope. | |
* This is the same as the `$transclude` | |
* parameter of directive controllers, see there for details. | |
* `function([scope], cloneLinkingFn, futureParentElement)`. | |
* | |
* #### Pre-linking function | |
* | |
* Executed before the child elements are linked. Not safe to do DOM transformation since the | |
* compiler linking function will fail to locate the correct elements for linking. | |
* | |
* #### Post-linking function | |
* | |
* Executed after the child elements are linked. | |
* | |
* Note that child elements that contain `templateUrl` directives will not have been compiled | |
* and linked since they are waiting for their template to load asynchronously and their own | |
* compilation and linking has been suspended until that occurs. | |
* | |
* It is safe to do DOM transformation in the post-linking function on elements that are not waiting | |
* for their async templates to be resolved. | |
* | |
* | |
* ### Transclusion | |
* | |
* Transclusion is the process of extracting a collection of DOM element from one part of the DOM and | |
* copying them to another part of the DOM, while maintaining their connection to the original AngularJS | |
* scope from where they were taken. | |
* | |
* Transclusion is used (often with {@link ngTransclude}) to insert the | |
* original contents of a directive's element into a specified place in the template of the directive. | |
* The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded | |
* content has access to the properties on the scope from which it was taken, even if the directive | |
* has isolated scope. | |
* See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}. | |
* | |
* This makes it possible for the widget to have private state for its template, while the transcluded | |
* content has access to its originating scope. | |
* | |
* <div class="alert alert-warning"> | |
* **Note:** When testing an element transclude directive you must not place the directive at the root of the | |
* DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives | |
* Testing Transclusion Directives}. | |
* </div> | |
* | |
* #### Transclusion Functions | |
* | |
* When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion | |
* function** to the directive's `link` function and `controller`. This transclusion function is a special | |
* **linking function** that will return the compiled contents linked to a new transclusion scope. | |
* | |
* <div class="alert alert-info"> | |
* If you are just using {@link ngTransclude} then you don't need to worry about this function, since | |
* ngTransclude will deal with it for us. | |
* </div> | |
* | |
* If you want to manually control the insertion and removal of the transcluded content in your directive | |
* then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery | |
* object that contains the compiled DOM, which is linked to the correct transclusion scope. | |
* | |
* When you call a transclusion function you can pass in a **clone attach function**. This function accepts | |
* two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded | |
* content and the `scope` is the newly created transclusion scope, to which the clone is bound. | |
* | |
* <div class="alert alert-info"> | |
* **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a translude function | |
* since you then get a fresh clone of the original DOM and also have access to the new transclusion scope. | |
* </div> | |
* | |
* It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone | |
* attach function**: | |
* | |
* ```js | |
* var transcludedContent, transclusionScope; | |
* | |
* $transclude(function(clone, scope) { | |
* element.append(clone); | |
* transcludedContent = clone; | |
* transclusionScope = scope; | |
* }); | |
* ``` | |
* | |
* Later, if you want to remove the transcluded content from your DOM then you should also destroy the | |
* associated transclusion scope: | |
* | |
* ```js | |
* transcludedContent.remove(); | |
* transclusionScope.$destroy(); | |
* ``` | |
* | |
* <div class="alert alert-info"> | |
* **Best Practice**: if you intend to add and remove transcluded content manually in your directive | |
* (by calling the transclude function to get the DOM and and calling `element.remove()` to remove it), | |
* then you are also responsible for calling `$destroy` on the transclusion scope. | |
* </div> | |
* | |
* The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat} | |
* automatically destroy their transluded clones as necessary so you do not need to worry about this if | |
* you are simply using {@link ngTransclude} to inject the transclusion into your directive. | |
* | |
* | |
* #### Transclusion Scopes | |
* | |
* When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion | |
* scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed | |
* when the directive's scope gets destroyed) but it inherits the properties of the scope from which it | |
* was taken. | |
* | |
* For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look | |
* like this: | |
* | |
* ```html | |
* <div ng-app> | |
* <div isolate> | |
* <div transclusion> | |
* </div> | |
* </div> | |
* </div> | |
* ``` | |
* | |
* The `$parent` scope hierarchy will look like this: | |
* | |
* ``` | |
* - $rootScope | |
* - isolate | |
* - transclusion | |
* ``` | |
* | |
* but the scopes will inherit prototypically from different scopes to their `$parent`. | |
* | |
* ``` | |
* - $rootScope | |
* - transclusion | |
* - isolate | |
* ``` | |
* | |
* | |
* ### Attributes | |
* | |
* The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the | |
* `link()` or `compile()` functions. It has a variety of uses. | |
* | |
* accessing *Normalized attribute names:* | |
* Directives like 'ngBind' can be expressed in many ways: 'ng:bind', `data-ng-bind`, or 'x-ng-bind'. | |
* the attributes object allows for normalized access to | |
* the attributes. | |
* | |
* * *Directive inter-communication:* All directives share the same instance of the attributes | |
* object which allows the directives to use the attributes object as inter directive | |
* communication. | |
* | |
* * *Supports interpolation:* Interpolation attributes are assigned to the attribute object | |
* allowing other directives to read the interpolated value. | |
* | |
* * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes | |
* that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also | |
* the only way to easily get the actual value because during the linking phase the interpolation | |
* hasn't been evaluated yet and so the value is at this time set to `undefined`. | |
* | |
* ```js | |
* function linkingFn(scope, elm, attrs, ctrl) { | |
* // get the attribute value | |
* console.log(attrs.ngModel); | |
* | |
* // change the attribute | |
* attrs.$set('ngModel', 'new value'); | |
* | |
* // observe changes to interpolated attribute | |
* attrs.$observe('ngModel', function(value) { | |
* console.log('ngModel has changed value to ' + value); | |
* }); | |
* } | |
* ``` | |
* | |
* ## Example | |
* | |
* <div class="alert alert-warning"> | |
* **Note**: Typically directives are registered with `module.directive`. The example below is | |
* to illustrate how `$compile` works. | |
* </div> | |
* | |
<example module="compileExample"> | |
<file name="index.html"> | |
<script> | |
angular.module('compileExample', [], function($compileProvider) { | |
// configure new 'compile' directive by passing a directive | |
// factory function. The factory function injects the '$compile' | |
$compileProvider.directive('compile', function($compile) { | |
// directive factory creates a link function | |
return function(scope, element, attrs) { | |
scope.$watch( | |
function(scope) { | |
// watch the 'compile' expression for changes | |
return scope.$eval(attrs.compile); | |
}, | |
function(value) { | |
// when the 'compile' expression changes | |
// assign it into the current DOM | |
element.html(value); | |
// compile the new DOM and link it to the current | |
// scope. | |
// NOTE: we only compile .childNodes so that | |
// we don't get into infinite loop compiling ourselves | |
$compile(element.contents())(scope); | |
} | |
); | |
}; | |
}); | |
}) | |
.controller('GreeterController', ['$scope', function($scope) { | |
$scope.name = 'Angular'; | |
$scope.html = 'Hello {{name}}'; | |
}]); | |
</script> | |
<div ng-controller="GreeterController"> | |
<input ng-model="name"> <br> | |
<textarea ng-model="html"></textarea> <br> | |
<div compile="html"></div> | |
</div> | |
</file> | |
<file name="protractor.js" type="protractor"> | |
it('should auto compile', function() { | |
var textarea = $('textarea'); | |
var output = $('div[compile]'); | |
// The initial state reads 'Hello Angular'. | |
expect(output.getText()).toBe('Hello Angular'); | |
textarea.clear(); | |
textarea.sendKeys('{{name}}!'); | |
expect(output.getText()).toBe('Angular!'); | |
}); | |
</file> | |
</example> | |
* | |
* | |
* @param {string|DOMElement} element Element or HTML string to compile into a template function. | |
* @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED. | |
* | |
* <div class="alert alert-error"> | |
* **Note:** Passing a `transclude` function to the $compile function is deprecated, as it | |
* e.g. will not use the right outer scope. Please pass the transclude function as a | |
* `parentBoundTranscludeFn` to the link function instead. | |
* </div> | |
* | |
* @param {number} maxPriority only apply directives lower than given priority (Only effects the | |
* root element(s), not their children) | |
* @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template | |
* (a DOM element/tree) to a scope. Where: | |
* | |
* * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to. | |
* * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the | |
* `template` and call the `cloneAttachFn` function allowing the caller to attach the | |
* cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is | |
* called as: <br> `cloneAttachFn(clonedElement, scope)` where: | |
* | |
* * `clonedElement` - is a clone of the original `element` passed into the compiler. | |
* * `scope` - is the current scope with which the linking function is working with. | |
* | |
* * `options` - An optional object hash with linking options. If `options` is provided, then the following | |
* keys may be used to control linking behavior: | |
* | |
* * `parentBoundTranscludeFn` - the transclude function made available to | |
* directives; if given, it will be passed through to the link functions of | |
* directives found in `element` during compilation. | |
* * `transcludeControllers` - an object hash with keys that map controller names | |
* to controller instances; if given, it will make the controllers | |
* available to directives. | |
* * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add | |
* the cloned elements; only needed for transcludes that are allowed to contain non html | |
* elements (e.g. SVG elements). See also the directive.controller property. | |
* | |
* Calling the linking function returns the element of the template. It is either the original | |
* element passed in, or the clone of the element if the `cloneAttachFn` is provided. | |
* | |
* After linking the view is not updated until after a call to $digest which typically is done by | |
* Angular automatically. | |
* | |
* If you need access to the bound view, there are two ways to do it: | |
* | |
* - If you are not asking the linking function to clone the template, create the DOM element(s) | |
* before you send them to the compiler and keep this reference around. | |
* ```js | |
* var element = $compile('<p>{{total}}</p>')(scope); | |
* ``` | |
* | |
* - if on the other hand, you need the element to be cloned, the view reference from the original | |
* example would not point to the clone, but rather to the original template that was cloned. In | |
* this case, you can access the clone via the cloneAttachFn: | |
* ```js | |
* var templateElement = angular.element('<p>{{total}}</p>'), | |
* scope = ....; | |
* | |
* var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) { | |
* //attach the clone to DOM document at the right place | |
* }); | |
* | |
* //now we have reference to the cloned DOM via `clonedElement` | |
* ``` | |
* | |
* | |
* For information on how the compiler works, see the | |
* {@link guide/compiler Angular HTML Compiler} section of the Developer Guide. | |

* <hr /> | |
* Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind` | |
* methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler} | |
* (unless executed during a digest). | |
* | |
* If you wish, you can manually delegate exceptions, e.g. | |

* @description | |
* The `$http` service is a core Angular service that facilitates communication with the remote | |
* HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest) | |
* object or via [JSONP](http://en.wikipedia.org/wiki/JSONP). | |
* | |
* For unit testing applications that use `$http` service, see | |
* {@link ngMock.$httpBackend $httpBackend mock}. | |
* | |
* For a higher level of abstraction, please check out the {@link ngResource.$resource | |
* $resource} service. | |
* | |
* The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by | |
* the $q service. While for simple usage patterns this doesn't matter much, for advanced usage | |
* it is important to familiarize yourself with these APIs and the guarantees they provide. | |
* | |
* | |
* ## General usage | |
* The `$http` service is a function which takes a single argument � a configuration object � | |
* that is used to generate an HTTP request and returns a {@link ng.$q promise} | |
* with two $http specific methods: `success` and `error`. | |
* | |
* ```js | |
* // Simple GET request example : | |
* $http.get('/someUrl'). | |
* success(function(data, status, headers, config) { | |
* // this callback will be called asynchronously | |
* // when the response is available | |
* }). | |
* error(function(data, status, headers, config) { | |
* // called asynchronously if an error occurs | |
* // or server returns response with an error status. | |
* }); | |
* ``` | |
* | |
* ```js | |
* // Simple POST request example (passing data) : | |
* $http.post('/someUrl', {msg:'hello word!'}). | |
* success(function(data, status, headers, config) { | |
* // this callback will be called asynchronously | |
* // when the response is available | |
* }). | |
* error(function(data, status, headers, config) { | |
* // called asynchronously if an error occurs | |
* // or server returns response with an error status. | |
* }); | |
* ``` | |
* | |
* | |
* Since the returned value of calling the $http function is a `promise`, you can also use | |
* the `then` method to register callbacks, and these callbacks will receive a single argument � | |
* an object representing the response. See the API signature and type info below for more | |
* details. | |
* | |
* A response status code between 200 and 299 is considered a success status and | |
* will result in the success callback being called. Note that if the response is a redirect, | |
* XMLHttpRequest will transparently follow it, meaning that the error callback will not be | |
* called for such responses. | |
* | |
* ## Writing Unit Tests that use $http | |
* When unit testing (using {@link ngMock ngMock}), it is necessary to call | |
* {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending | |
* request using trained responses. | |
* | |
* ``` | |
* $httpBackend.expectGET(...); | |
* $http.get(...); | |
* $httpBackend.flush(); | |
* ``` | |
* | |
* ## Shortcut methods | |
* | |
* Shortcut methods are also available. All shortcut methods require passing in the URL, and | |
* request data must be passed in for POST/PUT requests. | |
* | |
* ```js | |
* $http.get('/someUrl').success(successCallback); | |
* $http.post('/someUrl', data).success(successCallback); | |
* ``` | |
* | |
* Complete list of shortcut methods: | |
* | |
* - {@link ng.$http#get $http.get} | |
* - {@link ng.$http#head $http.head} | |
* - {@link ng.$http#post $http.post} | |
* - {@link ng.$http#put $http.put} | |
* - {@link ng.$http#delete $http.delete} | |
* - {@link ng.$http#jsonp $http.jsonp} | |
* - {@link ng.$http#patch $http.patch} | |
* | |
* | |
* ## Setting HTTP Headers | |
* | |
* The $http service will automatically add certain HTTP headers to all requests. These defaults | |
* can be fully configured by accessing the `$httpProvider.defaults.headers` configuration | |
* object, which currently contains this default configuration: | |
* | |
* - `$httpProvider.defaults.headers.common` (headers that are common for all requests): | |
* - `Accept: application/json, text/plain, * / *` | |
* - `$httpProvider.defaults.headers.post`: (header defaults for POST requests) | |
* - `Content-Type: application/json` | |
* - `$httpProvider.defaults.headers.put` (header defaults for PUT requests) | |
* - `Content-Type: application/json` | |
* | |
* To add or overwrite these defaults, simply add or remove a property from these configuration | |
* objects. To add headers for an HTTP method other than POST or PUT, simply add a new object | |
* with the lowercased HTTP method name as the key, e.g. | |
* `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }. | |
* | |
* The defaults can also be set at runtime via the `$http.defaults` object in the same | |
* fashion. For example: | |
* | |
* ``` | |
* module.run(function($http) { | |
* $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w' | |
* }); | |
* ``` | |
* | |
* In addition, you can supply a `headers` property in the config object passed when | |
* calling `$http(config)`, which overrides the defaults without changing them globally. | |
* | |
* To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis, | |
* Use the `headers` property, setting the desired header to `undefined`. For example: | |
* | |
* ```js | |
* var req = { | |
* method: 'POST', | |
* url: 'http://example.com', | |
* headers: { | |
* 'Content-Type': undefined | |
* }, | |
* data: { test: 'test' }, | |
* } | |
* | |
* $http(req).success(function(){...}).error(function(){...}); | |
* ``` | |
* | |
* ## Transforming Requests and Responses | |
* | |
* Both requests and responses can be transformed using transformation functions: `transformRequest` | |
* and `transformResponse`. These properties can be a single function that returns | |
* the transformed value (`{function(data, headersGetter, status)`) or an array of such transformation functions, | |
* which allows you to `push` or `unshift` a new transformation function into the transformation chain. | |
* | |
* ### Default Transformations | |
* | |
* The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and | |
* `defaults.transformResponse` properties. If a request does not provide its own transformations | |
* then these will be applied. | |
* | |
* You can augment or replace the default transformations by modifying these properties by adding to or | |
* replacing the array. | |
* | |
* Angular provides the following default transformations: | |
* | |
* Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`): | |
* | |
* - If the `data` property of the request configuration object contains an object, serialize it | |
* into JSON format. | |
* | |
* Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`): | |
* | |
* - If XSRF prefix is detected, strip it (see Security Considerations section below). | |
* - If JSON response is detected, deserialize it using a JSON parser. | |
* | |
* | |
* ### Overriding the Default Transformations Per Request | |
* | |
* If you wish override the request/response transformations only for a single request then provide | |
* `transformRequest` and/or `transformResponse` properties on the configuration object passed | |
* into `$http`. | |
* | |
* Note that if you provide these properties on the config object the default transformations will be | |
* overwritten. If you wish to augment the default transformations then you must include them in your | |
* local transformation array. | |
* | |
* The following code demonstrates adding a new response transformation to be run after the default response | |
* transformations have been run. | |
* | |
* ```js | |
* function appendTransform(defaults, transform) { | |
* | |
* // We can't guarantee that the default transformation is an array | |
* defaults = angular.isArray(defaults) ? defaults : [defaults]; | |
* | |
* // Append the new transformation to the defaults | |
* return defaults.concat(transform); | |
* } | |
* | |
* $http({ | |
* url: '...', | |
* method: 'GET', | |
* transformResponse: appendTransform($http.defaults.transformResponse, function(value) { | |
* return doTransform(value); | |
* }) | |
* }); | |
* ``` | |
* | |
* | |
* ## Caching | |
* | |
* To enable caching, set the request configuration `cache` property to `true` (to use default | |
* cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}). | |
* When the cache is enabled, `$http` stores the response from the server in the specified | |
* cache. The next time the same request is made, the response is served from the cache without | |
* sending a request to the server. | |
* | |
* Note that even if the response is served from cache, delivery of the data is asynchronous in | |
* the same way that real requests are. | |
* | |
* If there are multiple GET requests for the same URL that should be cached using the same | |
* cache, but the cache is not populated yet, only one request to the server will be made and | |
* the remaining requests will be fulfilled using the response from the first request. | |
* | |
* You can change the default cache to a new object (built with | |
* {@link ng.$cacheFactory `$cacheFactory`}) by updating the | |
* {@link ng.$http#defaults `$http.defaults.cache`} property. All requests who set | |
* their `cache` property to `true` will now use this cache object. | |
* | |
* If you set the default cache to `false` then only requests that specify their own custom | |
* cache object will be cached. | |
* | |
* ## Interceptors | |
* | |
* Before you start creating interceptors, be sure to understand the | |
* {@link ng.$q $q and deferred/promise APIs}. | |
* | |
* For purposes of global error handling, authentication, or any kind of synchronous or | |
* asynchronous pre-processing of request or postprocessing of responses, it is desirable to be | |
* able to intercept requests before they are handed to the server and | |
* responses before they are handed over to the application code that | |
* initiated these requests. The interceptors leverage the {@link ng.$q | |
* promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing. | |
* | |
* The interceptors are service factories that are registered with the `$httpProvider` by | |
* adding them to the `$httpProvider.interceptors` array. The factory is called and | |
* injected with dependencies (if specified) and returns the interceptor. | |
* | |
* There are two kinds of interceptors (and two kinds of rejection interceptors): | |
* | |
* * `request`: interceptors get called with a http `config` object. The function is free to | |
* modify the `config` object or create a new one. The function needs to return the `config` | |
* object directly, or a promise containing the `config` or a new `config` object. | |
* * `requestError`: interceptor gets called when a previous interceptor threw an error or | |
* resolved with a rejection. | |
* * `response`: interceptors get called with http `response` object. The function is free to | |
* modify the `response` object or create a new one. The function needs to return the `response` | |
* object directly, or as a promise containing the `response` or a new `response` object. | |
* * `responseError`: interceptor gets called when a previous interceptor threw an error or | |
* resolved with a rejection. | |
* | |
* | |
* ```js | |
* // register the interceptor as a service | |
* $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { | |
* return { | |
* // optional method | |
* 'request': function(config) { | |
* // do something on success | |
* return config; | |
* }, | |
* | |
* // optional method | |
* 'requestError': function(rejection) { | |
* // do something on error | |
* if (canRecover(rejection)) { | |
* return responseOrNewPromise | |
* } | |
* return $q.reject(rejection); | |
* }, | |
* | |
* | |
* | |
* // optional method | |
* 'response': function(response) { | |
* // do something on success | |
* return response; | |
* }, | |
* | |
* // optional method | |
* 'responseError': function(rejection) { | |
* // do something on error | |
* if (canRecover(rejection)) { | |
* return responseOrNewPromise | |
* } | |
* return $q.reject(rejection); | |
* } | |
* }; | |
* }); | |
* | |
* $httpProvider.interceptors.push('myHttpInterceptor'); | |
* | |
* | |
* // alternatively, register the interceptor via an anonymous factory | |
* $httpProvider.interceptors.push(function($q, dependency1, dependency2) { | |
* return { | |
* 'request': function(config) { | |
* // same as above | |
* }, | |
* | |
* 'response': function(response) { | |
* // same as above | |
* } | |
* }; | |
* }); | |
* ``` | |
* | |
* ## Security Considerations | |
* | |
* When designing web applications, consider security threats from: | |
* | |
* - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) | |
* - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) | |
* | |
* Both server and the client must cooperate in order to eliminate these threats. Angular comes | |
* pre-configured with strategies that address these issues, but for this to work backend server | |
* cooperation is required. | |
* | |
* ### JSON Vulnerability Protection | |
* | |
* A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) | |
* allows third party website to turn your JSON resource URL into | |
* [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To | |
* counter this your server can prefix all JSON requests with following string `")]}',\n"`. | |
* Angular will automatically strip the prefix before processing it as JSON. | |
* | |
* For example if your server needs to return: | |
* ```js | |
* ['one','two'] | |
* ``` | |
* | |
* which is vulnerable to attack, your server can return: | |
* ```js | |
* )]}', | |
* ['one','two'] | |
* ``` | |
* | |
* Angular will strip the prefix, before processing the JSON. | |
* | |
* | |
* ### Cross Site Request Forgery (XSRF) Protection | |
* | |
* [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is a technique by which | |
* an unauthorized site can gain your user's private data. Angular provides a mechanism | |
* to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie | |
* (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only | |
* JavaScript that runs on your domain could read the cookie, your server can be assured that | |
* the XHR came from JavaScript running on your domain. The header will not be set for | |
* cross-domain requests. | |
* | |
* To take advantage of this, your server needs to set a token in a JavaScript readable session | |
* cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the | |
* server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure | |
* that only JavaScript running on your domain could have sent the request. The token must be | |
* unique for each user and must be verifiable by the server (to prevent the JavaScript from | |
* making up its own tokens). We recommend that the token is a digest of your site's | |
* authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography)) | |
* for added security. | |
* | |
* The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName | |
* properties of either $httpProvider.defaults at config-time, $http.defaults at run-time, | |
* or the per-request config object. | |
* | |
* | |
* @param {object} config Object describing the request to be made and how it should be | |
* processed. The object has following properties: | |
* | |
* - **method** � `{string}` � HTTP method (e.g. 'GET', 'POST', etc) | |
* - **url** � `{string}` � Absolute or relative URL of the resource that is being requested. | |
* - **params** � `{Object.<string|Object>}` � Map of strings or objects which will be turned | |
* to `?key1=value1&key2=value2` after the url. If the value is not a string, it will be | |
* JSONified. | |
* - **data** � `{string|Object}` � Data to be sent as the request message data. | |
* - **headers** � `{Object}` � Map of strings or functions which return strings representing | |
* HTTP headers to send to the server. If the return value of a function is null, the | |
* header will not be sent. | |
* - **xsrfHeaderName** � `{string}` � Name of HTTP header to populate with the XSRF token. | |
* - **xsrfCookieName** � `{string}` � Name of cookie containing the XSRF token. | |
* - **transformRequest** � | |
* `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` � | |
* transform function or an array of such functions. The transform function takes the http | |
* request body and headers and returns its transformed (typically serialized) version. | |
* See {@link ng.$http#overriding-the-default-transformations-per-request | |
* Overriding the Default Transformations} | |
* - **transformResponse** � | |
* `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` � | |
* transform function or an array of such functions. The transform function takes the http | |
* response body, headers and status and returns its transformed (typically deserialized) version. | |
* See {@link ng.$http#overriding-the-default-transformations-per-request | |
* Overriding the Default Transformations} | |
* - **cache** � `{boolean|Cache}` � If true, a default $http cache will be used to cache the | |
* GET request, otherwise if a cache instance built with | |
* {@link ng.$cacheFactory $cacheFactory}, this cache will be used for | |
* caching. | |
* - **timeout** � `{number|Promise}` � timeout in milliseconds, or {@link ng.$q promise} | |
* that should abort the request when resolved. | |
* - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the | |
* XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials) | |
* for more information. | |
* - **responseType** - `{string}` - see | |
* [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType). | |
* | |
* @returns {HttpPromise} Returns a {@link ng.$q promise} object with the | |
* standard `then` method and two http specific methods: `success` and `error`. The `then` | |
* method takes two arguments a success and an error callback which will be called with a | |
* response object. The `success` and `error` methods take a single argument - a function that | |
* will be called when the request succeeds or fails respectively. The arguments passed into | |
* these functions are destructured representation of the response object passed into the | |
* `then` method. The response object has these properties: | |
* | |
* - **data** � `{string|Object}` � The response body transformed with the transform | |
* functions. | |
* - **status** � `{number}` � HTTP status code of the response. | |
* - **headers** � `{function([headerName])}` � Header getter function. | |
* - **config** � `{Object}` � The configuration object that was used to generate the request. | |
* - **statusText** � `{string}` � HTTP status text of the response. | |
* | |
* @property {Array.<Object>} pendingRequests Array of config objects for currently pending | |
* requests. This is primarily meant to be used for debugging purposes. | |
* | |

* | |
* @description | |
* | |
* Compiles a string with markup into an interpolation function. This service is used by the | |
* HTML {@link ng.$compile $compile} service for data binding. See | |
* {@link ng.$interpolateProvider $interpolateProvider} for configuring the | |
* interpolation markup. | |
* | |
* | |
* ```js | |
* var $interpolate = ...; // injected | |
* var exp = $interpolate('Hello {{name | uppercase}}!'); | |
* expect(exp({name:'Angular'}).toEqual('Hello ANGULAR!'); | |
* ``` | |
* | |
* `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is | |
* `true`, the interpolation function will return `undefined` unless all embedded expressions | |
* evaluate to a value other than `undefined`. | |
* | |
* ```js | |
* var $interpolate = ...; // injected | |
* var context = {greeting: 'Hello', name: undefined }; | |
* | |
* // default "forgiving" mode | |
* var exp = $interpolate('{{greeting}} {{name}}!'); | |
* expect(exp(context)).toEqual('Hello !'); | |
* | |
* // "allOrNothing" mode | |
* exp = $interpolate('{{greeting}} {{name}}!', false, null, true); | |
* expect(exp(context)).toBeUndefined(); | |
* context.name = 'Angular'; | |
* expect(exp(context)).toEqual('Hello Angular!'); | |
* ``` | |
* | |
* `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior. | |
* | |
* ####Escaped Interpolation | |
* $interpolate provides a mechanism for escaping interpolation markers. Start and end markers | |
* can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash). | |
* It will be rendered as a regular start/end marker, and will not be interpreted as an expression | |
* or binding. | |
* | |
* This enables web-servers to prevent script injection attacks and defacing attacks, to some | |
* degree, while also enabling code examples to work without relying on the | |
* {@link ng.directive:ngNonBindable ngNonBindable} directive. | |
* | |
* **For security purposes, it is strongly encouraged that web servers escape user-supplied data, | |
* replacing angle brackets (<, >) with &lt; and &gt; respectively, and replacing all | |
* interpolation start/end markers with their escaped counterparts.** | |
* | |
* Escaped interpolation markers are only replaced with the actual interpolation markers in rendered | |
* output when the $interpolate service processes the text. So, for HTML elements interpolated | |
* by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter | |
* set to `true`, the interpolated text must contain an unescaped interpolation expression. As such, | |
* this is typically useful only when user-data is used in rendering a template from the server, or | |
* when otherwise untrusted data is used by a directive. | |
* | |
* <example> | |
* <file name="index.html"> | |
* <div ng-init="username='A user'"> | |
* <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\} | |
* </p> | |
* <p><strong>{{username}}</strong> attempts to inject code which will deface the | |
* application, but fails to accomplish their task, because the server has correctly | |
* escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash) | |
* characters.</p> | |
* <p>Instead, the result of the attempted script injection is visible, and can be removed | |
* from the database by an administrator.</p> | |
* </div> | |
* </file> | |
* </example> | |
* | |
* @param {string} text The text with markup to interpolate. | |
* @param {boolean=} mustHaveExpression if set to true then the interpolation string must have | |
* embedded expression in order to return an interpolation function. Strings with no | |
* embedded expression will return null for the interpolation function. | |
* @param {string=} trustedContext when provided, the returned function passes the interpolated | |
* result through {@link ng.$sce#getTrusted $sce.getTrusted(interpolatedResult, | |
* trustedContext)} before returning it. Refer to the {@link ng.$sce $sce} service that | |
* provides Strict Contextual Escaping for details. | |
* @param {boolean=} allOrNothing if `true`, then the returned function returns undefined | |
* unless all embedded expressions evaluate to a value other than `undefined`. | |

/** | |
* @ngdoc service | |
* @name $interval | |
* | |
* @description | |
* Angular's wrapper for `window.setInterval`. The `fn` function is executed every `delay` | |
* milliseconds. | |
* | |
* The return value of registering an interval function is a promise. This promise will be | |
* notified upon each tick of the interval, and will be resolved after `count` iterations, or | |
* run indefinitely if `count` is not defined. The value of the notification will be the | |
* number of iterations that have run. | |
* To cancel an interval, call `$interval.cancel(promise)`. | |
* | |
* In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to | |
* move forward by `millis` milliseconds and trigger any functions scheduled to run in that | |
* time. | |
* | |
* <div class="alert alert-warning"> | |
* **Note**: Intervals created by this service must be explicitly destroyed when you are finished | |
* with them. In particular they are not automatically destroyed when a controller's scope or a | |
* directive's element are destroyed. | |
* You should take this into consideration and make sure to always cancel the interval at the | |
* appropriate moment. See the example below for more details on how and when to do this. | |
* </div> | |
* | |
* @param {function()} fn A function that should be called repeatedly. | |
* @param {number} delay Number of milliseconds between each function call. | |
* @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat | |
* indefinitely. | |
* @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise | |
* will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block. | |
* @returns {promise} A promise which will be notified on each iteration. | |

// Sandboxing Angular Expressions | |
// ------------------------------ | |
// Angular expressions are generally considered safe because these expressions only have direct | |
// access to `$scope` and locals. However, one can obtain the ability to execute arbitrary JS code by | |
// obtaining a reference to native JS functions such as the Function constructor. | |
// | |
// As an example, consider the following Angular expression: | |
// | |
// {}.toString.constructor('alert("evil JS code")') | |
// | |
// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits | |
// against the expression language, but not to prevent exploits that were enabled by exposing | |
// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good | |
// practice and therefore we are not even trying to protect against interaction with an object | |
// explicitly exposed in this way. | |
// | |
// In general, it is not possible to access a Window object from an angular expression unless a | |
// window or some DOM object that has a reference to window is published onto a Scope. | |
// Similarly we prevent invocations of function known to be dangerous, as well as assignments to | |
// native objects. | |

/** | |
* @ngdoc service | |
* @name $q | |
* @requires $rootScope | |
* | |
* @description | |
* A service that helps you run functions asynchronously, and use their return values (or exceptions) | |
* when they are done processing. | |
* | |
* This is an implementation of promises/deferred objects inspired by | |
* [Kris Kowal's Q](https://github.com/kriskowal/q). | |
* | |
* $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred | |
* implementations, and the other which resembles ES6 promises to some degree. | |
* | |
* # $q constructor | |
* | |
* The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver` | |
* function as the first argument. This is similar to the native Promise implementation from ES6 Harmony, | |
* see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise). | |
* | |
* While the constructor-style use is supported, not all of the supporting methods from ES6 Harmony promises are | |
* available yet. | |
* | |
* It can be used like so: | |
* | |
* ```js | |
* // for the purpose of this example let's assume that variables `$q` and `okToGreet` | |
* // are available in the current lexical scope (they could have been injected or passed in). | |
* | |
* function asyncGreet(name) { | |
* // perform some asynchronous operation, resolve or reject the promise when appropriate. | |
* return $q(function(resolve, reject) { | |
* setTimeout(function() { | |
* if (okToGreet(name)) { | |
* resolve('Hello, ' + name + '!'); | |
* } else { | |
* reject('Greeting ' + name + ' is not allowed.'); | |
* } | |
* }, 1000); | |
* }); | |
* } | |
* | |
* var promise = asyncGreet('Robin Hood'); | |
* promise.then(function(greeting) { | |
* alert('Success: ' + greeting); | |
* }, function(reason) { | |
* alert('Failed: ' + reason); | |
* }); | |
* ``` | |
* | |
* Note: progress/notify callbacks are not currently supported via the ES6-style interface. | |
* | |
* However, the more traditional CommonJS-style usage is still available, and documented below. | |
* | |
* [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an | |
* interface for interacting with an object that represents the result of an action that is | |
* performed asynchronously, and may or may not be finished at any given point in time. | |
* | |
* From the perspective of dealing with error handling, deferred and promise APIs are to | |
* asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming. | |
* | |
* ```js | |
* // for the purpose of this example let's assume that variables `$q` and `okToGreet` | |
* // are available in the current lexical scope (they could have been injected or passed in). | |
* | |
* function asyncGreet(name) { | |
* var deferred = $q.defer(); | |
* | |
* setTimeout(function() { | |
* deferred.notify('About to greet ' + name + '.'); | |
* | |
* if (okToGreet(name)) { | |
* deferred.resolve('Hello, ' + name + '!'); | |
* } else { | |
* deferred.reject('Greeting ' + name + ' is not allowed.'); | |
* } | |
* }, 1000); | |
* | |
* return deferred.promise; | |
* } | |
* | |
* var promise = asyncGreet('Robin Hood'); | |
* promise.then(function(greeting) { | |
* alert('Success: ' + greeting); | |
* }, function(reason) { | |
* alert('Failed: ' + reason); | |
* }, function(update) { | |
* alert('Got notification: ' + update); | |
* }); | |
* ``` | |
* | |
* At first it might not be obvious why this extra complexity is worth the trouble. The payoff | |
* comes in the way of guarantees that promise and deferred APIs make, see | |
* https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md. | |
* | |
* Additionally the promise api allows for composition that is very hard to do with the | |
* traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach. | |
* For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the | |
* section on serial or parallel joining of promises. | |
* | |
* # The Deferred API | |
* | |
* A new instance of deferred is constructed by calling `$q.defer()`. | |
* | |
* The purpose of the deferred object is to expose the associated Promise instance as well as APIs | |
* that can be used for signaling the successful or unsuccessful completion, as well as the status | |
* of the task. | |
* | |
* **Methods** | |
* | |
* - `resolve(value)` � resolves the derived promise with the `value`. If the value is a rejection | |
* constructed via `$q.reject`, the promise will be rejected instead. | |
* - `reject(reason)` � rejects the derived promise with the `reason`. This is equivalent to | |
* resolving it with a rejection constructed via `$q.reject`. | |
* - `notify(value)` - provides updates on the status of the promise's execution. This may be called | |
* multiple times before the promise is either resolved or rejected. | |
* | |
* **Properties** | |
* | |
* - promise � `{Promise}` � promise object associated with this deferred. | |
* | |
* | |
* # The Promise API | |
* | |
* A new promise instance is created when a deferred instance is created and can be retrieved by | |
* calling `deferred.promise`. | |
* | |
* The purpose of the promise object is to allow for interested parties to get access to the result | |
* of the deferred task when it completes. | |
* | |
* **Methods** | |
* | |
* - `then(successCallback, errorCallback, notifyCallback)` � regardless of when the promise was or | |
* will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously | |
* as soon as the result is available. The callbacks are called with a single argument: the result | |
* or rejection reason. Additionally, the notify callback may be called zero or more times to | |
* provide a progress indication, before the promise is resolved or rejected. | |
* | |
* This method *returns a new promise* which is resolved or rejected via the return value of the | |
* `successCallback`, `errorCallback`. It also notifies via the return value of the | |
* `notifyCallback` method. The promise cannot be resolved or rejected from the notifyCallback | |
* method. | |
* | |
* - `catch(errorCallback)` � shorthand for `promise.then(null, errorCallback)` | |
* | |
* - `finally(callback, notifyCallback)` � allows you to observe either the fulfillment or rejection of a promise, | |
* but to do so without modifying the final value. This is useful to release resources or do some | |
* clean-up that needs to be done whether the promise was rejected or resolved. See the [full | |
* specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for | |
* more information. | |
* | |
* # Chaining promises | |
* | |
* Because calling the `then` method of a promise returns a new derived promise, it is easily | |
* possible to create a chain of promises: | |
* | |
* ```js | |
* promiseB = promiseA.then(function(result) { | |
* return result + 1; | |
* }); | |
* | |
* // promiseB will be resolved immediately after promiseA is resolved and its value | |
* // will be the result of promiseA incremented by 1 | |
* ``` | |
* | |
* It is possible to create chains of any length and since a promise can be resolved with another | |
* promise (which will defer its resolution further), it is possible to pause/defer resolution of | |
* the promises at any point in the chain. This makes it possible to implement powerful APIs like | |
* $http's response interceptors. | |
* | |
* | |
* # Differences between Kris Kowal's Q and $q | |
* | |
* There are two main differences: | |
* | |
* - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation | |
* mechanism in angular, which means faster propagation of resolution or rejection into your | |
* models and avoiding unnecessary browser repaints, which would result in flickering UI. | |
* - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains | |
* all the important functionality needed for common async tasks. | |
* | |
* # Testing | |
* | |
* ```js | |
* it('should simulate promise', inject(function($q, $rootScope) { | |
* var deferred = $q.defer(); | |
* var promise = deferred.promise; | |
* var resolvedValue; | |
* | |
* promise.then(function(value) { resolvedValue = value; }); | |
* expect(resolvedValue).toBeUndefined(); | |
* | |
* // Simulate resolving of promise | |
* deferred.resolve(123); | |
* // Note that the 'then' function does not get called synchronously. | |
* // This is because we want the promise API to always be async, whether or not | |
* // it got called synchronously or asynchronously. | |
* expect(resolvedValue).toBeUndefined(); | |
* | |
* // Propagate promise resolution to 'then' functions using $apply(). | |
* $rootScope.$apply(); | |
* expect(resolvedValue).toEqual(123); | |
* })); | |
* ``` | |
* | |
* @param {function(function, function)} resolver Function which is responsible for resolving or | |
* rejecting the newly created promise. The first parameter is a function which resolves the | |
* promise, the second parameter is a function which rejects the promise. | |
* | |
* @returns {Promise} The newly created promise. | |

* current promise, you have to "rethrow" the error by returning a rejection constructed via | |
* `reject`. | |
* | |
* ```js | |
* promiseB = promiseA.then(function(result) { | |
* // success: do something and resolve promiseB | |
* // with the old or a new result | |
* return result; | |

* // resolve promiseB with newPromiseOrValue, | |

/** | |
* DESIGN NOTES | |
* | |
* The design decisions behind the scope are heavily favored for speed and memory consumption. | |
* | |
* The typical use of scope is to watch the expressions, which most of the time return the same | |
* value as last time so we optimize the operation. | |
* | |
* Closures construction is expensive in terms of speed as well as memory: | |
* - No closures, instead use prototypical inheritance for API | |
* - Internal state needs to be stored on scope directly, which means that private state is | |
* exposed as $$____ properties | |
* | |
* Loop operations are optimized by using while(count--) { ... } | |
* - this means that in order to keep the same order of execution as addition we have to add | |
* items to the array at the beginning (unshift) instead of at the end (push) | |
* | |
* Child scopes are created and removed often | |
* - Using an array would be slow since inserts in middle are expensive so we use linked list | |
* | |
* There are few watches then a lot of observers. This is why you don't want the observer to be | |
* implemented in the same way as watch. Watch requires return of initialization function which | |
* are expensive to construct. | |

* @kind function | |
* | |
* @description | |
* Registers a `listener` callback to be executed whenever the `watchExpression` changes. | |
* | |
* - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest | |
* $digest()} and should return the value that will be watched. (Since | |
* {@link ng.$rootScope.Scope#$digest $digest()} reruns when it detects changes the | |
* `watchExpression` can execute multiple times per | |
* {@link ng.$rootScope.Scope#$digest $digest()} and should be idempotent.) | |
* - The `listener` is called only when the value from the current `watchExpression` and the | |
* previous call to `watchExpression` are not equal (with the exception of the initial run, | |
* see below). Inequality is determined according to reference inequality, | |
* [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators) | |
* via the `!==` Javascript operator, unless `objectEquality == true` | |
* (see next point) | |
* - When `objectEquality == true`, inequality of the `watchExpression` is determined | |
* according to the {@link angular.equals} function. To save the value of the object for | |
* later comparison, the {@link angular.copy} function is used. This therefore means that | |
* watching complex objects will have adverse memory and performance implications. | |
* - The watch `listener` may change the model, which may trigger other `listener`s to fire. | |
* This is achieved by rerunning the watchers until no changes are detected. The rerun | |
* iteration limit is 10 to prevent an infinite loop deadlock. | |
* | |
* | |
* If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called, | |
* you can register a `watchExpression` function with no `listener`. (Since `watchExpression` | |
* can execute multiple times per {@link ng.$rootScope.Scope#$digest $digest} cycle when a | |
* change is detected, be prepared for multiple calls to your listener.) | |
* | |
* After a watcher is registered with the scope, the `listener` fn is called asynchronously | |
* (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the | |
* watcher. In rare cases, this is undesirable because the listener is called when the result | |
* of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you | |
* can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the | |
* listener was called due to initialization. | |
* | |
* | |
* | |
* # Example | |
* ```js | |
// let's assume that scope was dependency injected as the $rootScope | |
var scope = $rootScope; | |

* @ngdoc method | |
* @name $rootScope.Scope#$digest | |
* @kind function | |
* | |
* @description | |
* Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and | |
* its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change | |
* the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers} | |
* until no more listeners are firing. This means that it is possible to get into an infinite | |
* loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of | |
* iterations exceeds 10. | |
* | |
* Usually, you don't call `$digest()` directly in | |
* {@link ng.directive:ngController controllers} or in | |
* {@link ng.$compileProvider#directive directives}. | |
* Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within | |
* a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`. | |
* | |
* If you want to be notified whenever `$digest()` is called, | |
* you can register a `watchExpression` function with | |
* {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`. | |
* | |
* In unit tests, you may need to call `$digest()` to simulate the scope life cycle. | |
* | |
* # Example | |
* ```js | |
var scope = ...; | |
scope.name = 'misko'; | |

// the listener is always called during the first $digest loop after it was registered | |
expect(scope.counter).toEqual(1); | |
scope.$digest(); | |
// but now it will not be called unless the value changes | |

* @description | |
* | |
* `$sce` is a service that provides Strict Contextual Escaping services to AngularJS. | |
* | |
* # Strict Contextual Escaping | |
* | |
* Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain | |
* contexts to result in a value that is marked as safe to use for that context. One example of | |
* such a context is binding arbitrary html controlled by the user via `ng-bind-html`. We refer | |
* to these contexts as privileged or SCE contexts. | |
* | |
* As of version 1.2, Angular ships with SCE enabled by default. | |
* | |
* Note: When enabled (the default), IE<11 in quirks mode is not supported. In this mode, IE<11 allow | |
* one to execute arbitrary javascript by the use of the expression() syntax. Refer | |
* <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them. | |
* You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>` | |
* to the top of your HTML document. | |
* | |
* SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for | |
* security vulnerabilities such as XSS, clickjacking, etc. a lot easier. | |
* | |
* Here's an example of a binding in a privileged context: | |
* | |
* ``` | |
* <input ng-model="userHtml"> | |
* <div ng-bind-html="userHtml"></div> | |
* ``` | |
* | |
* Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE | |
* disabled, this application allows the user to render arbitrary HTML into the DIV. | |
* In a more realistic example, one may be rendering user comments, blog articles, etc. via | |
* bindings. (HTML is just one example of a context where rendering user controlled input creates | |
* security vulnerabilities.) | |
* | |
* For the case of HTML, you might use a library, either on the client side, or on the server side, | |
* to sanitize unsafe HTML before binding to the value and rendering it in the document. | |
* | |
* How would you ensure that every place that used these types of bindings was bound to a value that | |
* was sanitized by your library (or returned as safe for rendering by your server?) How can you | |
* ensure that you didn't accidentally delete the line that sanitized the value, or renamed some | |
* properties/fields and forgot to update the binding to the sanitized value? | |
* | |
* To be secure by default, you want to ensure that any such bindings are disallowed unless you can | |
* determine that something explicitly says it's safe to use a value for binding in that | |
* context. You can then audit your code (a simple grep would do) to ensure that this is only done | |
* for those values that you can easily tell are safe - because they were received from your server, | |
* sanitized by your library, etc. You can organize your codebase to help with this - perhaps | |
* allowing only the files in a specific directory to do this. Ensuring that the internal API | |
* exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task. | |
* | |
* In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} | |
* (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to | |
* obtain values that will be accepted by SCE / privileged contexts. | |
* | |
* | |
* ## How does it work? | |
* | |
* In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted | |
* $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link | |
* ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the | |
* {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. | |
* | |
* As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link | |
* ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly | |
* simplified): | |
* | |
* ``` | |
* var ngBindHtmlDirective = ['$sce', function($sce) { | |
* return function(scope, element, attr) { | |
* scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { | |
* element.html(value || ''); | |
* }); | |
* }; | |
* }]; | |
* ``` | |
* | |
* ## Impact on loading templates | |
* | |
* This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as | |
* `templateUrl`'s specified by {@link guide/directive directives}. | |
* | |
* By default, Angular only loads templates from the same domain and protocol as the application | |
* document. This is done by calling {@link ng.$sce#getTrustedResourceUrl | |
* $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or | |
* protocols, you may either either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist | |
* them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value. | |
* | |
* *Please note*: | |
* The browser's | |
* [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) | |
* and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) | |
* policy apply in addition to this and may further restrict whether the template is successfully | |
* loaded. This means that without the right CORS policy, loading templates from a different domain | |
* won't work on all browsers. Also, loading templates from `file://` URL does not work on some | |
* browsers. | |
* | |
* ## This feels like too much overhead | |
* | |
* It's important to remember that SCE only applies to interpolation expressions. | |
* | |
* If your expressions are constant literals, they're automatically trusted and you don't need to | |
* call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g. | |
* `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works. | |
* | |
* Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them | |
* through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here. | |
* | |
* The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load | |
* templates in `ng-include` from your application's domain without having to even know about SCE. | |
* It blocks loading templates from other domains or loading templates over http from an https | |
* served document. You can change these by setting your own custom {@link | |
* ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link | |
* ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs. | |
* | |
* This significantly reduces the overhead. It is far easier to pay the small overhead and have an | |
* application that's secure and can be audited to verify that with much more ease than bolting | |
* security onto an application later. | |
* | |
* <a name="contexts"></a> | |
* ## What trusted context types are supported? | |
* | |
* | Context | Notes | | |
* |---------------------|----------------| | |
* | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. | | |
* | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. | | |
* | `$sce.URL` | For URLs that are safe to follow as links. Currently unused (`<a href=` and `<img src=` sanitize their urls and don't constitute an SCE context. | | |
* | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.) <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. | | |
* | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. | | |
* | |
* ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a> | |
* | |
* Each element in these arrays must be one of the following: | |
* | |
* - **'self'** | |
* - The special **string**, `'self'`, can be used to match against all URLs of the **same | |
* domain** as the application document using the **same protocol**. | |
* - **String** (except the special value `'self'`) | |
* - The string is matched against the full *normalized / absolute URL* of the resource | |
* being tested (substring matches are not good enough.) | |
* - There are exactly **two wildcard sequences** - `*` and `**`. All other characters | |
* match themselves. | |
* - `*`: matches zero or more occurrences of any character other than one of the following 6 | |
* characters: '`:`', '`/`', '`.`', '`?`', '`&`' and ';'. It's a useful wildcard for use | |
* in a whitelist. | |
* - `**`: matches zero or more occurrences of *any* character. As such, it's not | |
* not appropriate to use in for a scheme, domain, etc. as it would match too much. (e.g. | |
* http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might | |
* not have been the intention.) Its usage at the very end of the path is ok. (e.g. | |
* http://foo.example.com/templates/**). | |
* - **RegExp** (*see caveat below*) | |
* - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax | |
* (and all the inevitable escaping) makes them *harder to maintain*. It's easy to | |
* accidentally introduce a bug when one updates a complex expression (imho, all regexes should | |
* have good test coverage.). For instance, the use of `.` in the regex is correct only in a | |
* small number of cases. A `.` character in the regex used when matching the scheme or a | |
* subdomain could be matched against a `:` or literal `.` that was likely not intended. It | |
* is highly recommended to use the string patterns and only fall back to regular expressions | |
* if they as a last resort. | |
* - The regular expression must be an instance of RegExp (i.e. not a string.) It is | |
* matched against the **entire** *normalized / absolute URL* of the resource being tested | |
* (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags | |
* present on the RegExp (such as multiline, global, ignoreCase) are ignored. | |
* - If you are generating your JavaScript from some other templating engine (not | |
* recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), | |
* remember to escape your regular expression (and be aware that you might need more than | |
* one level of escaping depending on your templating engine and the way you interpolated | |
* the value.) Do make use of your platform's escaping mechanism as it might be good | |
* enough before coding your own. e.g. Ruby has | |
* [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) | |
* and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). | |
* Javascript lacks a similar built in function for escaping. Take a look at Google | |
* Closure library's [goog.string.regExpEscape(s)]( | |
* http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). | |
* | |

* ## Can I disable SCE completely? | |
* | |
* Yes, you can. However, this is strongly discouraged. SCE gives you a lot of security benefits | |
* for little coding overhead. It will be much harder to take an SCE disabled application and | |
* either secure it on your own or enable SCE at a later stage. It might make sense to disable SCE | |
* for cases where you have a lot of existing code that was written before SCE was introduced and | |
* you're migrating them a module at a time. | |
* | |
* That said, here's how you can completely disable SCE: | |
* | |
* ``` | |
* angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) { | |
* // Completely disable SCE. For demonstration purposes only! | |
* // Do not use in new projects. | |
* $sceProvider.enabled(false); | |
* }); | |
* ``` | |
* | |

/* Design notes on the default implementation for SCE. | |
* | |
* The API contract for the SCE delegate | |
* ------------------------------------- | |
* The SCE delegate object must provide the following 3 methods: | |
* | |
* - trustAs(contextEnum, value) | |
* This method is used to tell the SCE service that the provided value is OK to use in the | |
* contexts specified by contextEnum. It must return an object that will be accepted by | |
* getTrusted() for a compatible contextEnum and return this value. | |
* | |
* - valueOf(value) | |
* For values that were not produced by trustAs(), return them as is. For values that were | |
* produced by trustAs(), return the corresponding input value to trustAs. Basically, if | |
* trustAs is wrapping the given values into some type, this operation unwraps it when given | |
* such a value. | |
* | |
* - getTrusted(contextEnum, value) | |
* This function should return the a value that is safe to use in the context specified by | |
* contextEnum or throw and exception otherwise. | |
* | |
* NOTE: This contract deliberately does NOT state that values returned by trustAs() must be | |
* opaque or wrapped in some holder object. That happens to be an implementation detail. For | |
* instance, an implementation could maintain a registry of all trusted objects by context. In | |
* such a case, trustAs() would return the same object that was passed in. getTrusted() would | |
* return the same object passed in if it was found in the registry under a compatible context or | |
* throw an exception otherwise. An implementation might only wrap values some of the time based | |
* on some criteria. getTrusted() might return a value and not throw an exception for special | |
* constants or objects even if not wrapped. All such implementations fulfill this contract. | |
* | |
* | |
* A note on the inheritance model for SCE contexts | |
* ------------------------------------------------ | |
* I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This | |
* is purely an implementation details. | |
* | |
* The contract is simply this: | |
* | |
* getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value) | |
* will also succeed. | |
* | |
* Inheritance happens to capture this in a natural way. In some future, we | |
* may not use inheritance anymore. That is OK because no code outside of | |
* sce.js and sceSpecs.js would need to be aware of this detail. | |

* | |
* Implementation Notes for non-IE browsers | |
* ---------------------------------------- | |
* Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM, | |
* results both in the normalizing and parsing of the URL. Normalizing means that a relative | |
* URL will be resolved into an absolute URL in the context of the application document. | |
* Parsing means that the anchor node's host, hostname, protocol, port, pathname and related | |
* properties are all populated to reflect the normalized URL. This approach has wide | |
* compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See | |
* http://www.aptana.com/reference/html/api/HTMLAnchorElement.html | |
* | |
* Implementation Notes for IE | |
* --------------------------- | |
* IE >= 8 and <= 10 normalizes the URL when assigned to the anchor node similar to the other | |
* browsers. However, the parsed components will not be set if the URL assigned did not specify | |
* them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We | |
* work around that by performing the parsing in a 2nd step by taking a previously normalized | |
* URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the | |
* properties such as protocol, hostname, port, etc. | |
* | |
* IE7 does not normalize the URL when assigned to an anchor node. (Apparently, it does, if one | |
* uses the inner HTML approach to assign the URL as part of an HTML snippet - | |
* http://stackoverflow.com/a/472729) However, setting img[src] does normalize the URL. | |
* Unfortunately, setting img[src] to something like "javascript:foo" on IE throws an exception. | |
* Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that | |
* method and IE < 8 is unsupported. | |

* @description | |
* | |
* Filters are just functions which transform input to an output. However filters need to be | |
* Dependency Injected. To achieve this a filter definition consists of a factory function which is | |
* annotated with dependencies and is responsible for creating a filter function. | |
* | |
* ```js | |
* // Filter registration | |
* function MyModule($provide, $filterProvider) { | |
* // create a service to demonstrate injection (not always needed) | |
* $provide.value('greet', function(name){ | |
* return 'Hello ' + name + '!'; | |
* }); | |
* | |
* // register a filter factory which uses the | |
* // greet service to demonstrate DI. | |
* $filterProvider.register('greet', function(greet){ | |
* // return the filter function which uses the greet service | |
* // to generate salutation | |
* return function(text) { | |
* // filters need to be forgiving so check input validity | |
* return text && greet(text) || text; | |
* }; | |
* }); | |
* } | |
* ``` | |
* | |
* The filter function is registered with the `$injector` under the filter name suffix with | |
* `Filter`. | |
* | |
* ```js | |
* it('should be the same instance', inject( | |
* function($filterProvider) { | |
* $filterProvider.register('reverse', function(){ | |
* return ...; | |

* @ngdoc filter | |

* @kind function | |
* | |
* @description | |
* Selects a subset of items from `array` and returns it as a new array. | |
* | |
* @param {Array} array The source array. | |
* @param {string|Object|function()} expression The predicate to be used for selecting items from | |
* `array`. | |
* | |
* Can be one of: | |
* | |
* - `string`: The string is used for matching against the contents of the `array`. All strings or | |
* objects with string properties in `array` that match this string will be returned. This also | |
* applies to nested object properties. | |
* The predicate can be negated by prefixing the string with `!`. | |
* | |
* - `Object`: A pattern object can be used to filter specific properties on objects contained | |
* by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items | |
* which have property `name` containing "M" and property `phone` containing "1". A special | |
* property name `$` can be used (as in `{$:"text"}`) to accept a match against any | |
* property of the object or its nested object properties. That's equivalent to the simple | |
* substring match with a `string` as described above. The predicate can be negated by prefixing | |
* the string with `!`. | |
* For example `{name: "!M"}` predicate will return an array of items which have property `name` | |
* not containing "M". | |
* | |
* Note that a named property will match properties on the same level only, while the special | |
* `$` property will match properties on the same level or deeper. E.g. an array item like | |
* `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but | |
* **will** be matched by `{$: 'John'}`. | |
* | |
* - `function(value, index)`: A predicate function can be used to write arbitrary filters. The | |
* function is called for each element of `array`. The final result is an array of those | |
* elements that the predicate returned true for. | |
* | |
* @param {function(actual, expected)|true|undefined} comparator Comparator which is used in | |
* determining if the expected value (from the filter expression) and actual value (from | |
* the object in the array) should be considered a match. | |
* | |
* Can be one of: | |
* | |
* - `function(actual, expected)`: | |
* The function will be given the object value and the predicate value to compare and | |
* should return true if both values should be considered equal. | |
* | |
* - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`. | |
* This is essentially strict comparison of expected and actual. | |
* | |
* - `false|undefined`: A short hand for a function which will look for a substring match in case | |
* insensitive way. | |
* | |

* * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199) | |
* * `'MMMM'`: Month in year (January-December) | |
* * `'MMM'`: Month in year (Jan-Dec) | |
* * `'MM'`: Month in year, padded (01-12) | |
* * `'M'`: Month in year (1-12) | |
* * `'dd'`: Day in month, padded (01-31) | |
* * `'d'`: Day in month (1-31) | |
* * `'EEEE'`: Day in Week,(Sunday-Saturday) | |
* * `'EEE'`: Day in Week, (Sun-Sat) | |
* * `'HH'`: Hour in day, padded (00-23) | |
* * `'H'`: Hour in day (0-23) | |
* * `'hh'`: Hour in AM/PM, padded (01-12) | |
* * `'h'`: Hour in AM/PM, (1-12) | |
* * `'mm'`: Minute in hour, padded (00-59) | |
* * `'m'`: Minute in hour (0-59) | |
* * `'ss'`: Second in minute, padded (00-59) | |
* * `'s'`: Second in minute (0-59) | |
* * `'.sss' or ',sss'`: Millisecond in second, padded (000-999) | |
* * `'a'`: AM/PM marker | |
* * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200) | |
* * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year | |
* * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year | |
* | |
* `format` string can also be one of the following predefined | |
* {@link guide/i18n localizable formats}: | |
* | |
* * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale | |
* (e.g. Sep 3, 2010 12:05:08 PM) | |
* * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 PM) | |

* * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010) | |
* * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010) | |
* * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10) | |
* * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM) | |
* * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM) | |
* | |
* `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g. | |
* `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence | |
* (e.g. `"h 'o''clock'"`). | |
* | |
* @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or | |
* number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its | |
* shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is | |
* specified in the string input, the time is considered to be in the local timezone. | |
* @param {string=} format Formatting rules (see Description). If not specified, | |
* `mediumDate` is used. | |
* @param {string=} timezone Timezone to be used for formatting. Right now, only `'UTC'` is supported. | |
* If not specified, the timezone of the browser will be used. | |
* @returns {string} Formatted string or the input if input is not recognized as date/millis. | |

* @kind function | |
* | |
* @description | |
* Orders a specified `array` by the `expression` predicate. It is ordered alphabetically | |
* for strings and numerically for numbers. Note: if you notice numbers are not being sorted | |
* correctly, make sure they are actually being saved as numbers and not strings. | |
* | |
* @param {Array} array The array to sort. | |
* @param {function(*)|string|Array.<(function(*)|string)>=} expression A predicate to be | |
* used by the comparator to determine the order of elements. | |
* | |
* Can be one of: | |
* | |
* - `function`: Getter function. The result of this function will be sorted using the | |
* `<`, `=`, `>` operator. | |
* - `string`: An Angular expression. The result of this expression is used to compare elements | |
* (for example `name` to sort by a property called `name` or `name.substr(0, 3)` to sort by | |
* 3 first characters of a property called `name`). The result of a constant expression | |
* is interpreted as a property name to be used in comparisons (for example `"special name"` | |
* to sort object by the value of their `special name` property). An expression can be | |
* optionally prefixed with `+` or `-` to control ascending or descending sort order | |
* (for example, `+name` or `-name`). If no property is provided, (e.g. `'+'`) then the array | |
* element itself is used to compare where sorting. | |
* - `Array`: An array of function or string predicates. The first predicate in the array | |
* is used for sorting, but when two items are equivalent, the next predicate is used. | |
* | |
* If the predicate is missing or empty then it defaults to `'+'`. | |
* | |
* @param {boolean=} reverse Reverse the order of the array. | |
* @returns {Array} Sorted copy of the source array. | |

* @ngdoc directive | |

* @restrict E | |
* | |
* @description | |
* Directive that instantiates | |
* {@link form.FormController FormController}. | |
* | |
* If the `name` attribute is specified, the form controller is published onto the current scope under | |
* this name. | |
* | |
* # Alias: {@link ng.directive:ngForm `ngForm`} | |
* | |
* In Angular forms can be nested. This means that the outer form is valid when all of the child | |
* forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so | |
* Angular provides the {@link ng.directive:ngForm `ngForm`} directive which behaves identically to | |
* `<form>` but can be nested. This allows you to have nested forms, which is very useful when | |
* using Angular validation directives in forms that are dynamically generated using the | |
* {@link ng.directive:ngRepeat `ngRepeat`} directive. Since you cannot dynamically generate the `name` | |
* attribute of input elements using interpolation, you have to wrap each set of repeated inputs in an | |
* `ngForm` directive and nest these in an outer `form` element. | |
* | |
* | |
* # CSS classes | |
* - `ng-valid` is set if the form is valid. | |
* - `ng-invalid` is set if the form is invalid. | |
* - `ng-pristine` is set if the form is pristine. | |
* - `ng-dirty` is set if the form is dirty. | |
* - `ng-submitted` is set if the form was submitted. | |
* | |
* Keep in mind that ngAnimate can detect each of these classes when added and removed. | |
* | |
* | |
* # Submitting a form and preventing the default action | |
* | |
* Since the role of forms in client-side Angular applications is different than in classical | |
* roundtrip apps, it is desirable for the browser not to translate the form submission into a full | |
* page reload that sends the data to the server. Instead some javascript logic should be triggered | |
* to handle the form submission in an application-specific way. | |
* | |
* For this reason, Angular prevents the default action (form submission to the server) unless the | |
* `<form>` element has an `action` attribute specified. | |
* | |
* You can use one of the following two ways to specify what javascript method should be called when | |
* a form is submitted: | |
* | |
* - {@link ng.directive:ngSubmit ngSubmit} directive on the form element | |
* - {@link ng.directive:ngClick ngClick} directive on the first | |
* button or input field of type submit (input[type=submit]) | |
* | |
* To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit} | |
* or {@link ng.directive:ngClick ngClick} directives. | |
* This is because of the following form submission rules in the HTML specification: | |
* | |
* - If a form has only one input field then hitting enter in this field triggers form submit | |
* (`ngSubmit`) | |
* - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter | |
* doesn't trigger submit | |
* - if a form has one or more input fields and one or more buttons or input[type=submit] then | |
* hitting enter in any of the input fields will trigger the click handler on the *first* button or | |
* input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`) | |
* | |
* Any pending `ngModelOptions` changes will take place immediately when an enclosing form is | |
* submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` | |
* to have access to the updated model. | |
* | |
* ## Animation Hooks | |
* | |
* Animations in ngForm are triggered when any of the associated CSS classes are added and removed. | |
* These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any | |
* other validations that are performed within the form. Animations in ngForm are similar to how | |
* they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well | |
* as JS animations. | |
* | |
* The following example shows a simple way to utilize CSS transitions to style a form element | |
* that has been rendered as invalid after it has been validated: | |
* | |
* <pre> | |
* //be sure to include ngAnimate as a module to hook into more | |
* //advanced animations | |
* .my-form { | |
* transition:0.5s linear all; | |
* background: white; | |
* } | |
* .my-form.ng-invalid { | |
* background: red; | |
* color:white; | |
* } | |
* </pre> | |
* | |
* @example | |

<file name="index.html"> | |

* @ngdoc input | |
* @name input[text] | |
* | |
* @description | |
* Standard HTML text input with angular data binding, inherited by most of the `input` elements. | |
* | |
* | |
* @param {string} ngModel Assignable angular expression to data-bind to. | |
* @param {string=} name Property name of the form under which the control is published. | |
* @param {string=} required Adds `required` validation error key if the value is not entered. | |
* @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to | |
* the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of | |
* `required` when you want to data-bind to the `required` attribute. | |
* @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than | |
* minlength. | |
* @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than | |
* maxlength. Setting the attribute to a negative or non-numeric value, allows view values of | |
* any length. | |
* @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string | |
* that contains the regular expression body that will be converted to a regular expression | |
* as in the ngPattern directive. | |
* @param {string=} ngPattern Sets `pattern` validation error key if the ngModel value does not match | |
* a RegExp found by evaluating the Angular expression given in the attribute value. | |
* If the expression evaluates to a RegExp object then this is used directly. | |
* If the expression is a string then it will be converted to a RegExp after wrapping it in `^` and `$` | |
* characters. For instance, `"abc"` will be converted to `new RegExp('^abc$')`. | |
* @param {string=} ngChange Angular expression to be executed when input changes due to user | |
* interaction with the input element. | |
* @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input. | |
* This parameter is ignored for input[type=password] controls, which will never trim the | |
* input. | |
* | |
* @example | |

* @ngdoc input | |
* @name input[month] | |
* | |
* @description | |
* Input with month validation and transformation. In browsers that do not yet support | |
* the HTML5 month input, a text element will be used. In that case, the text must be entered in a valid ISO-8601 | |
* month format (yyyy-MM), for example: `2009-01`. | |
* | |
* The model must always be a Date object, otherwise Angular will throw an error. | |
* Invalid `Date` objects (dates whose `getTime()` is `NaN`) will be rendered as an empty string. | |
* If the model is not set to the first of the month, the next view to model update will set it | |
* to the first of the month. | |
* | |
* The timezone to be used to read/write the `Date` instance in the model can be defined using | |
* {@link ng.directive:ngModelOptions ngModelOptions}. By default, this is the timezone of the browser. | |
* | |
* @param {string} ngModel Assignable angular expression to data-bind to. | |
* @param {string=} name Property name of the form under which the control is published. | |
* @param {string=} min Sets the `min` validation error key if the value entered is less than `min`. This must be | |
* a valid ISO month format (yyyy-MM). | |
* @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`. This must | |
* be a valid ISO month format (yyyy-MM). | |
* @param {string=} required Sets `required` validation error key if the value is not entered. | |
* @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to | |
* the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of | |
* `required` when you want to data-bind to the `required` attribute. | |
* @param {string=} ngChange Angular expression to be executed when input changes due to user | |
* interaction with the input element. | |

Parsers are used to sanitize / convert the {@link ngModel.NgModelController#$viewValue | |

* | |
* @property {Object.<string, function>} $validators A collection of validators that are applied | |
* whenever the model value changes. The key value within the object refers to the name of the | |
* validator while the function refers to the validation operation. The validation operation is | |
* provided with the model value as an argument and must return a true or false value depending | |
* on the response of that validation. | |
* | |
* ```js | |
* ngModel.$validators.validCharacters = function(modelValue, viewValue) { | |
* var value = modelValue || viewValue; | |
* return /[0-9]+/.test(value) && | |

* @property {Object.<string, function>} $asyncValidators A collection of validations that are expected to | |

* is expected to return a promise when it is run during the model validation process. Once the promise | |
* is delivered then the validation status will be set to true when fulfilled and false when rejected. | |
* When the asynchronous validators are triggered, each of the validators will run in parallel and the model | |
* value will only be updated once all validators have been fulfilled. As long as an asynchronous validator | |
* is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators | |
* will only run once all synchronous validators have passed. | |
* | |
* Please note that if $http is used then it is important that the server returns a success HTTP response code | |

* @description | |
* | |
* `NgModelController` provides API for the {@link ngModel `ngModel`} directive. | |
* The controller contains services for data-binding, validation, CSS updates, and value formatting | |
* and parsing. It purposefully does not contain any logic which deals with DOM rendering or | |
* listening to DOM events. | |
* Such DOM related logic should be provided by other directives which make use of | |
* `NgModelController` for data-binding to control elements. | |
* Angular provides this DOM logic for most {@link input `input`} elements. | |
* At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example | |
* custom control example} that uses `ngModelController` to bind to `contenteditable` elements. | |
* | |
* @example | |
* ### Custom Control Example | |
* This example shows how to use `NgModelController` with a custom control to achieve | |
* data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`) | |
* collaborate together to achieve the desired result. | |
* | |
* Note that `contenteditable` is an HTML5 attribute, which tells the browser to let the element | |
* contents be edited in place by the user. This will not work on older browsers. | |
* | |
* We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize} | |
* module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`). | |
* However, as we are using `$sce` the model can still decide to provide unsafe content if it marks | |
* that content using the `$sce` service. | |
* | |
* <example name="NgModelController" module="customControl" deps="angular-sanitize.js"> | |
<file name="style.css"> | |
[contenteditable] { | |
border: 1px solid black; | |
background-color: white; | |

* | |
* In this case, you can run into difficulties if you try to update the ngModel's `$modelValue` | |

* @description | |
* Update the view value. | |
* | |
* This method should be called when an input directive want to change the view value; typically, | |
* this is done from within a DOM event handler. | |
* | |
* For example {@link ng.directive:input input} calls it when the value of the input changes and | |
* {@link ng.directive:select select} calls it when an option is selected. | |
* | |
* If the new `value` is an object (rather than a string or a number), we should make a copy of the | |
* object before passing it to `$setViewValue`. This is because `ngModel` does not perform a deep | |
* watch of objects, it only looks for a change of identity. If you only change the property of | |
* the object then ngModel will not realise that the object has changed and will not invoke the | |
* `$parsers` and `$validators` pipelines. | |
* | |
* For this reason, you should not change properties of the copy once it has been passed to | |
* `$setViewValue`. Otherwise you may cause the model value on the scope to change incorrectly. | |
* | |
* When this method is called, the new `value` will be staged for committing through the `$parsers` | |
* and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged | |
* value sent directly for processing, finally to be applied to `$modelValue` and then the | |
* **expression** specified in the `ng-model` attribute. | |
* | |
* Lastly, all the registered change listeners, in the `$viewChangeListeners` list, are called. | |
* | |
* In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn` | |
* and the `default` trigger is not listed, all those actions will remain pending until one of the | |
* `updateOn` events is triggered on the DOM element. | |
* All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions} | |
* directive is used with a custom debounce for this particular event. | |

* @description | |
* The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a | |
* property on the scope using {@link ngModel.NgModelController NgModelController}, | |
* which is created and exposed by this directive. | |
* | |
* `ngModel` is responsible for: | |
* | |
* - Binding the view into the model, which other directives such as `input`, `textarea` or `select` | |
* require. | |
* - Providing validation behavior (i.e. required, number, email, url). | |
* - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors). | |
* - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`, `ng-untouched`) including animations. | |
* - Registering the control with its parent {@link ng.directive:form form}. | |
* | |
* Note: `ngModel` will try to bind to the property given by evaluating the expression on the | |
* current scope. If the property doesn't already exist on this scope, it will be created | |
* implicitly and added to the scope. | |
* | |
* For best practices on using `ngModel`, see: | |
* | |
* - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes) | |
* | |
* For basic examples, how to use `ngModel`, see: | |
* | |
* - {@link ng.directive:input input} | |
* - {@link input[text] text} | |
* - {@link input[checkbox] checkbox} | |
* - {@link input[radio] radio} | |
* - {@link input[number] number} | |
* - {@link input[email] email} | |
* - {@link input[url] url} | |
* - {@link input[date] date} | |
* - {@link input[datetime-local] datetime-local} | |
* - {@link input[time] time} | |
* - {@link input[month] month} | |
* - {@link input[week] week} | |
* - {@link ng.directive:select select} | |
* - {@link ng.directive:textarea textarea} | |
* | |
* # CSS classes | |
* The following CSS classes are added and removed on the associated input/select/textarea element | |
* depending on the validity of the model. | |
* | |
* - `ng-valid`: the model is valid | |
* - `ng-invalid`: the model is invalid | |
* - `ng-valid-[key]`: for each valid key added by `$setValidity` | |
* - `ng-invalid-[key]`: for each invalid key added by `$setValidity` | |
* - `ng-pristine`: the control hasn't been interacted with yet | |
* - `ng-dirty`: the control has been interacted with | |
* - `ng-touched`: the control has been blurred | |
* - `ng-untouched`: the control hasn't been blurred | |
* - `ng-pending`: any `$asyncValidators` are unfulfilled | |
* | |
* Keep in mind that ngAnimate can detect each of these classes when added and removed. | |

* Animations within models are triggered when any of the associated CSS classes are added and removed | |
* on the input element which is attached to the model. These classes are: `.ng-pristine`, `.ng-dirty`, | |
* `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself. | |
* The animations that are triggered within ngModel are similar to how they work in ngClass and | |
* animations can be hooked into using CSS transitions, keyframes as well as JS animations. | |
* | |
* The following example shows a simple way to utilize CSS transitions to style an input element | |
* that has been rendered as invalid after it has been validated: | |
* | |
* <pre> | |
* //be sure to include ngAnimate as a module to hook into more | |
* //advanced animations | |
* .my-input { | |
* transition:0.5s linear all; | |
* background: white; | |
* } | |
* .my-input.ng-invalid { | |
* background: red; | |
* color:white; | |
* } | |
* </pre> | |
* | |
* @example | |
* <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample"> | |
<file name="index.html"> | |
<script> | |
angular.module('inputExample', []) | |
.controller('ExampleController', ['$scope', function($scope) { | |
$scope.val = '1'; | |
}]); | |
</script> | |
<style> | |
.my-input { | |
-webkit-transition:all linear 0.5s; | |
transition:all linear 0.5s; | |
background: transparent; | |
} | |
.my-input.ng-invalid { | |
color:white; | |
background: red; | |
} | |
</style> | |
Update input to see transitions when valid/invalid. | |
Integer is a valid value. | |
<form name="testForm" ng-controller="ExampleController"> | |
<input ng-model="val" ng-pattern="/^\d+$/" name="anim" class="my-input" /> | |
</form> | |
</file> | |
* </example> | |
* | |
* ## Binding to a getter/setter | |
* | |
* Sometimes it's helpful to bind `ngModel` to a getter/setter function. A getter/setter is a | |
* function that returns a representation of the model when called with zero arguments, and sets | |
* the internal state of a model when called with an argument. It's sometimes useful to use this | |
* for models that have an internal representation that's different than what the model exposes | |
* to the view. | |
* | |
* <div class="alert alert-success"> | |
* **Best Practice:** It's best to keep getters fast because Angular is likely to call them more | |
* frequently than other parts of your code. | |
* </div> | |
* | |
* You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that | |
* has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to | |
* a `<form>`, which will enable this behavior for all `<input>`s within it. See | |
* {@link ng.directive:ngModelOptions `ngModelOptions`} for more. | |
* | |
* The following example shows how to use `ngModel` with a getter/setter: | |
* | |
* @example | |
* <example name="ngModel-getter-setter" module="getterSetterExample"> | |
<file name="index.html"> | |
<div ng-controller="ExampleController"> | |
<form name="userForm"> | |
Name: | |
<input type="text" name="userName" | |
ng-model="user.name" | |
ng-model-options="{ getterSetter: true }" /> | |
</form> | |
<pre>user.name = <span ng-bind="user.name()"></span></pre> | |
</div> | |
</file> | |
<file name="app.js"> | |
angular.module('getterSetterExample', []) | |

name: function(newName) { | |
if (angular.isDefined(newName)) { | |

/** | |
* @ngdoc directive | |
* @name ngList | |
* | |
* @description | |
* Text input that converts between a delimited string and an array of strings. The default | |
* delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom | |
* delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`. | |
* | |
* The behaviour of the directive is affected by the use of the `ngTrim` attribute. | |
* * If `ngTrim` is set to `"false"` then whitespace around both the separator and each | |
* list item is respected. This implies that the user of the directive is responsible for | |
* dealing with whitespace but also allows you to use whitespace as a delimiter, such as a | |
* tab or newline character. | |
* * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected | |
* when joining the list items back together) and whitespace around each list item is stripped | |
* before it is added to the model. | |

/** | |
* @ngdoc directive | |
* @name ngModelOptions | |
* | |
* @description | |
* Allows tuning how model updates are done. Using `ngModelOptions` you can specify a custom list of | |
* events that will trigger a model update and/or a debouncing delay so that the actual update only | |
* takes place when a timer expires; this timer will be reset after another change takes place. | |
* | |
* Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might | |
* be different than the value in the actual model. This means that if you update the model you | |
* should also invoke {@link ngModel.NgModelController `$rollbackViewValue`} on the relevant input field in | |
* order to make sure it is synchronized with the model and that any debounced action is canceled. | |
* | |
* The easiest way to reference the control's {@link ngModel.NgModelController `$rollbackViewValue`} | |
* method is by making sure the input is placed inside a form that has a `name` attribute. This is | |
* important because `form` controllers are published to the related scope under the name in their | |
* `name` attribute. | |
* | |
* Any pending changes will take place immediately when an enclosing form is submitted via the | |
* `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit` | |
* to have access to the updated model. | |
* | |
* `ngModelOptions` has an effect on the element it's declared on and its descendants. | |
* | |
* @param {Object} ngModelOptions options to apply to the current model. Valid keys are: | |
* - `updateOn`: string specifying which event should the input be bound to. You can set several | |
* events using an space delimited list. There is a special event called `default` that | |
* matches the default events belonging of the control. | |
* - `debounce`: integer value which contains the debounce model update value in milliseconds. A | |
* value of 0 triggers an immediate update. If an object is supplied instead, you can specify a | |
* custom value for each event. For example: | |
* `ng-model-options="{ updateOn: 'default blur', debounce: {'default': 500, 'blur': 0} }"` | |
* - `allowInvalid`: boolean value which indicates that the model can be set with values that did | |
* not validate correctly instead of the default behavior of setting the model to undefined. | |
* - `getterSetter`: boolean value which determines whether or not to treat functions bound to | |
`ngModel` as getters/setters. | |
* - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for | |
* `<input type="date">`, `<input type="time">`, ... . Right now, the only supported value is `'UTC'`, | |
* otherwise the default timezone of the browser will be used. | |
* | |
* @example | |
The following example shows how to override immediate updates. Changes on the inputs within the | |
form will update the model only when the control loses focus (blur event). If `escape` key is | |
pressed while the input field is focused, the value is reset to the value in the current model. | |

* @ngdoc directive | |
* @name ngBind | |
* @restrict AC | |
* | |
* @description | |
* The `ngBind` attribute tells Angular to replace the text content of the specified HTML element | |
* with the value of a given expression, and to update the text content when the value of that | |
* expression changes. | |
* | |
* Typically, you don't use `ngBind` directly, but instead you use the double curly markup like | |
* `{{ expression }}` which is similar but less verbose. | |
* | |
* It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily | |
* displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an | |
* element attribute, it makes the bindings invisible to the user while the page is loading. | |
* | |
* An alternative solution to this problem would be using the | |
* {@link ng.directive:ngCloak ngCloak} directive. | |
* | |
* | |
* @element ANY | |
* @param {expression} ngBind {@link guide/expression Expression} to evaluate. | |
* | |
* @example | |
* Enter a name in the Live Preview text box; the greeting below the text box changes instantly. | |

/** | |
* @ngdoc directive | |

* @restrict AC | |
* | |
* @description | |
* The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding | |
* an expression that represents all classes to be added. | |
* | |
* The directive operates in three different ways, depending on which of three types the expression | |
* evaluates to: | |
* | |
* 1. If the expression evaluates to a string, the string should be one or more space-delimited class | |
* names. | |
* | |
* 2. If the expression evaluates to an array, each element of the array should be a string that is | |
* one or more space-delimited class names. | |
* | |
* 3. If the expression evaluates to an object, then for each key-value pair of the | |
* object with a truthy value the corresponding key is used as a class name. | |
* | |
* The directive won't add duplicate classes if a particular class was already set. | |
* | |
* When the expression changes, the previously added classes are removed and only then the | |
* new classes are added. | |
* | |
* @animations | |
* add - happens just before the class is applied to the element | |
* remove - happens just before the class is removed from the element | |
* | |
* @element ANY | |
* @param {expression} ngClass {@link guide/expression Expression} to eval. The result | |
* of the evaluation can be a string representing space delimited class | |
* names, an array, or a map of class names to boolean values. In the case of a map, the | |
* names of the properties whose values are truthy will be added as css classes to the | |
* element. | |
* | |

</example> | |
## ngClass and pre-existing CSS3 Transitions/Animations | |
The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure. | |
Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder | |
any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure | |
to view the step by step details of {@link ng.$animate#addClass $animate.addClass} and | |
{@link ng.$animate#removeClass $animate.removeClass}. | |

* For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}). | |
* | |
* ```css | |
* [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak { | |
* display: none !important; | |
* } | |
* ``` | |
* | |
* When this css rule is loaded by the browser, all html elements (including their children) that | |
* are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive | |
* during the compilation of the template it deletes the `ngCloak` element attribute, making | |
* the compiled element visible. | |
* | |
* For the best result, the `angular.js` script must be loaded in the head section of the html | |
* document; alternatively, the css rule above must be included in the external stylesheet of the | |
* application. | |
* | |
* Legacy browsers, like IE7, do not provide attribute selector support (added in CSS 2.1) so they | |
* cannot match the `[ng\:cloak]` selector. To work around this limitation, you must add the css | |
* class `ng-cloak` in addition to the `ngCloak` directive as shown in the example below. | |
* | |
* @element ANY | |
* | |
* @example | |
<example> | |
<file name="index.html"> | |
<div id="template1" ng-cloak>{{ 'hello' }}</div> | |
<div id="template2" ng-cloak class="ng-cloak">{{ 'hello IE7' }}</div> | |

/** | |
* @ngdoc directive | |
* @name ngController | |
* | |
* @description | |
* The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular | |
* supports the principles behind the Model-View-Controller design pattern. | |
* | |
* MVC components in angular: | |
* | |
* * Model � Models are the properties of a scope; scopes are attached to the DOM where scope properties | |
* are accessed through bindings. | |
* * View � The template (HTML with data bindings) that is rendered into the View. | |
* * Controller � The `ngController` directive specifies a Controller class; the class contains business | |
* logic behind the application to decorate the scope with functions and values | |
* | |
* Note that you can also attach controllers to the DOM by declaring it in a route definition | |
* via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller | |
* again using `ng-controller` in the template itself. This will cause the controller to be attached | |
* and executed twice. | |
* | |
* @element ANY | |
* @scope | |
* @priority 500 | |
* @param {expression} ngController Name of a constructor function registered with the current | |
* {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression} | |
* that on the current scope evaluates to a constructor function. | |
* | |
* The controller instance can be published into a scope property by specifying | |
* `ng-controller="as propertyName"`. | |
* | |
* If the current `$controllerProvider` is configured to use globals (via | |
* {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may | |
* also be the name of a globally accessible constructor function (not recommended). | |
* | |
* @example | |
* Here is a simple form for editing user contact information. Adding, removing, clearing, and | |
* greeting are methods declared on the controller (see source tab). These methods can | |
* easily be called from the angular markup. Any changes to the data are automatically reflected | |
* in the View without the need for a manual update. | |
* | |
* Two different declaration styles are included below: | |
* | |
* * one binds methods and properties directly onto the controller using `this`: | |
* `ng-controller="SettingsController1 as settings"` | |
* * one injects `$scope` into the controller: | |
* `ng-controller="SettingsController2"` | |
* | |
* The second option is more common in the Angular community, and is generally used in boilerplates | |
* and in this guide. However, there are advantages to binding properties directly to the controller | |
* and avoiding scope. | |
* | |
* * Using `controller as` makes it obvious which controller you are accessing in the template when | |
* multiple controllers apply to an element. | |
* * If you are writing your controllers as classes you have easier access to the properties and | |
* methods, which will appear on the scope, from inside the controller code. | |
* * Since there is always a `.` in the bindings, you don't have to worry about prototypal | |
* inheritance masking primitives. | |
* | |
* This example demonstrates the `controller as` syntax. | |
* | |
* <example name="ngControllerAs" module="controllerAsExample"> | |
* <file name="index.html"> | |
* <div id="ctrl-as-exmpl" ng-controller="SettingsController1 as settings"> | |

/** | |
* @ngdoc directive | |
* @name ngCsp | |
* | |
* @element html | |
* @description | |
* Enables [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) support. | |
* | |
* This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps. | |
* | |
* CSP forbids apps to use `eval` or `Function(string)` generated functions (among other things). | |
* For Angular to be CSP compatible there are only two things that we need to do differently: | |
* | |
* - don't use `Function` constructor to generate optimized value getters | |
* - don't inject custom stylesheet into the document | |
* | |
* AngularJS uses `Function(string)` generated functions as a speed optimization. Applying the `ngCsp` | |
* directive will cause Angular to use CSP compatibility mode. When this mode is on AngularJS will | |
* evaluate all expressions up to 30% slower than in non-CSP mode, but no security violations will | |
* be raised. | |
* | |
* CSP forbids JavaScript to inline stylesheet rules. In non CSP mode Angular automatically | |
* includes some CSS rules (e.g. {@link ng.directive:ngCloak ngCloak}). | |
* To make those directives work in CSP mode, include the `angular-csp.css` manually. | |
* | |
* Angular tries to autodetect if CSP is active and automatically turn on the CSP-safe mode. This | |
* autodetection however triggers a CSP error to be logged in the console: | |
* | |
* ``` | |
* Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of | |
* script in the following Content Security Policy directive: "default-src 'self'". Note that | |
* 'script-src' was not explicitly set, so 'default-src' is used as a fallback. | |
* ``` | |
* | |
* This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp` | |
* directive on the root element of the application or on the `angular.js` script tag, whichever | |
* appears first in the html document. | |
* | |
* *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.* | |
* | |
* @example | |
* This example shows how to apply the `ngCsp` directive to the `html` tag. | |

/** | |
* @ngdoc directive | |
* @name ngIf | |
* @restrict A | |
* | |
* @description | |
* The `ngIf` directive removes or recreates a portion of the DOM tree based on an | |
* {expression}. If the expression assigned to `ngIf` evaluates to a false | |
* value then the element is removed from the DOM, otherwise a clone of the | |
* element is reinserted into the DOM. | |
* | |
* `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the | |
* element in the DOM rather than changing its visibility via the `display` css property. A common | |
* case when this difference is significant is when using css selectors that rely on an element's | |
* position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes. | |
* | |
* Note that when an element is removed using `ngIf` its scope is destroyed and a new scope | |
* is created when the element is restored. The scope created within `ngIf` inherits from | |
* its parent scope using | |
* [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance). | |
* An important implication of this is if `ngModel` is used within `ngIf` to bind to | |
* a javascript primitive defined in the parent scope. In this case any modifications made to the | |
* variable within the child scope will override (hide) the value in the parent scope. | |
* | |
* Also, `ngIf` recreates elements using their compiled state. An example of this behavior | |
* is if an element's class attribute is directly modified after it's compiled, using something like | |
* jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element | |
* the added class will be lost because the original compiled state is used to regenerate the element. | |
* | |
* Additionally, you can provide animations via the `ngAnimate` module to animate the `enter` | |
* and `leave` effects. | |
* | |
* @animations | |
* enter - happens just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container | |
* leave - happens just before the `ngIf` contents are removed from the DOM | |
* | |
* @element ANY | |
* @scope | |
* @priority 600 | |
* @param {expression} ngIf If the {@link guide/expression expression} is falsy then | |
* the element is removed from the DOM tree. If it is truthy a copy of the compiled | |

* The `ngNonBindable` directive tells Angular not to compile or bind the contents of the current | |

/** | |
* @ngdoc directive | |
* @name ngPluralize | |
* @restrict EA | |
* | |
* @description | |
* `ngPluralize` is a directive that displays messages according to en-US localization rules. | |
* These rules are bundled with angular.js, but can be overridden | |
* (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive | |
* by specifying the mappings between | |
* [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html) | |
* and the strings to be displayed. | |
* | |
* # Plural categories and explicit number rules | |
* There are two | |
* [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html) | |
* in Angular's default en-US locale: "one" and "other". | |
* | |
* While a plural category may match many numbers (for example, in en-US locale, "other" can match | |
* any number that is not 1), an explicit number rule can only match one number. For example, the | |
* explicit number rule for "3" matches the number 3. There are examples of plural categories | |
* and explicit number rules throughout the rest of this documentation. | |
* | |
* # Configuring ngPluralize | |
* You configure ngPluralize by providing 2 attributes: `count` and `when`. | |
* You can also provide an optional attribute, `offset`. | |
* | |
* The value of the `count` attribute can be either a string or an {@link guide/expression | |
* Angular expression}; these are evaluated on the current scope for its bound value. | |
* | |
* The `when` attribute specifies the mappings between plural categories and the actual | |
* string to be displayed. The value of the attribute should be a JSON object. | |
* | |
* The following example shows how to configure ngPluralize: | |
* | |
* ```html | |
* <ng-pluralize count="personCount" | |
when="{'0': 'Nobody is viewing.', | |
* 'one': '1 person is viewing.', | |
* 'other': '{} people are viewing.'}"> | |
* </ng-pluralize> | |
*``` | |
* | |
* In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not | |
* specify this rule, 0 would be matched to the "other" category and "0 people are viewing" | |
* would be shown instead of "Nobody is viewing". You can specify an explicit number rule for | |
* other numbers, for example 12, so that instead of showing "12 people are viewing", you can | |
* show "a dozen people are viewing". | |
* | |
* You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted | |
* into pluralized strings. In the previous example, Angular will replace `{}` with | |
* <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder | |
* for <span ng-non-bindable>{{numberExpression}}</span>. | |
* | |
* # Configuring ngPluralize with offset | |
* The `offset` attribute allows further customization of pluralized text, which can result in | |
* a better user experience. For example, instead of the message "4 people are viewing this document", | |
* you might display "John, Kate and 2 others are viewing this document". | |
* The offset attribute allows you to offset a number by any desired value. | |
* Let's take a look at an example: | |
* | |
* ```html | |
* <ng-pluralize count="personCount" offset=2 | |
* when="{'0': 'Nobody is viewing.', | |
* '1': '{{person1}} is viewing.', | |
* '2': '{{person1}} and {{person2}} are viewing.', | |
* 'one': '{{person1}}, {{person2}} and one other person are viewing.', | |
* 'other': '{{person1}}, {{person2}} and {} other people are viewing.'}"> | |
* </ng-pluralize> | |
* ``` | |
* | |
* Notice that we are still using two plural categories(one, other), but we added | |
* three explicit number rules 0, 1 and 2. | |
* When one person, perhaps John, views the document, "John is viewing" will be shown. | |
* When three people view the document, no explicit number rule is found, so | |
* an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category. | |
* In this case, plural category 'one' is matched and "John, Mary and one other person are viewing" | |
* is shown. | |
* | |
* Note that when you specify offsets, you must provide explicit number rules for | |
* numbers from 0 up to and including the offset. If you use an offset of 3, for example, | |
* you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for | |
* plural categories "one" and "other". | |
* | |
* @param {string|expression} count The variable to be bound to. | |
* @param {string} when The mapping between plural category to its corresponding strings. | |
* @param {number=} offset Offset to deduct from the total number. | |
* | |

/** | |
* @ngdoc directive | |
* @name ngRepeat | |
* | |
* @description | |
* The `ngRepeat` directive instantiates a template once per item from a collection. Each template | |
* instance gets its own scope, where the given loop variable is set to the current collection item, | |
* and `$index` is set to the item index or key. | |
* | |
* Special properties are exposed on the local scope of each template instance, including: | |
* | |
* | Variable | Type | Details | | |
* |-----------|-----------------|-----------------------------------------------------------------------------| | |
* | `$index` | {@type number} | iterator offset of the repeated element (0..length-1) | | |
* | `$first` | {@type boolean} | true if the repeated element is first in the iterator. | | |
* | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. | | |
* | `$last` | {@type boolean} | true if the repeated element is last in the iterator. | | |
* | `$even` | {@type boolean} | true if the iterator position `$index` is even (otherwise false). | | |
* | `$odd` | {@type boolean} | true if the iterator position `$index` is odd (otherwise false). | | |
* | |
* Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}. | |
* This may be useful when, for instance, nesting ngRepeats. | |
* | |
* # Special repeat start and end points | |
* To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending | |
* the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively. | |
* The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on) | |
* up to and including the ending HTML tag where **ng-repeat-end** is placed. | |
* | |
* The example below makes use of this feature: | |
* ```html | |
* <header ng-repeat-start="item in items"> | |
* Header {{ item }} | |
* </header> | |
* <div class="body"> | |
* Body {{ item }} | |
* </div> | |
* <footer ng-repeat-end> | |
* Footer {{ item }} | |
* </footer> | |
* ``` | |
* | |
* And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to: | |
* ```html | |
* <header> | |
* Header A | |
* </header> | |
* <div class="body"> | |
* Body A | |
* </div> | |
* <footer> | |
* Footer A | |
* </footer> | |
* <header> | |
* Header B | |
* </header> | |
* <div class="body"> | |
* Body B | |
* </div> | |
* <footer> | |
* Footer B | |
* </footer> | |
* ``` | |
* | |
* The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such | |
* as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**). | |
* | |
* @animations | |
* **.enter** - when a new item is added to the list or when an item is revealed after a filter | |
* | |
* **.leave** - when an item is removed from the list or when an item is filtered out | |
* | |
* **.move** - when an adjacent item is filtered out causing a reorder or when the item contents are reordered | |
* | |
* @element ANY | |
* @scope | |
* @priority 1000 | |
* @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These | |
* formats are currently supported: | |
* | |
* * `variable in expression` � where variable is the user defined loop variable and `expression` | |
* is a scope expression giving the collection to enumerate. | |
* | |
* For example: `album in artist.albums`. | |
* | |
* * `(key, value) in expression` � where `key` and `value` can be any user defined identifiers, | |
* and `expression` is the scope expression giving the collection to enumerate. | |
* | |
* For example: `(name, age) in {'adam':10, 'amalie':12}`. | |
* | |
* * `variable in expression track by tracking_expression` � You can also provide an optional tracking function | |
* which can be used to associate the objects in the collection with the DOM elements. If no tracking function | |
* is specified the ng-repeat associates elements by identity in the collection. It is an error to have | |
* more than one tracking function to resolve to the same key. (This would mean that two distinct objects are | |
* mapped to the same DOM element, which is not possible.) Filters should be applied to the expression, | |
* before specifying a tracking expression. | |
* | |
* For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements | |
* will be associated by item identity in the array. | |
* | |
* For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique | |
* `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements | |
* with the corresponding item in the array by identity. Moving the same object in array would move the DOM | |
* element in the same way in the DOM. | |
* | |
* For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this | |
* case the object identity does not matter. Two objects are considered equivalent as long as their `id` | |
* property is same. | |
* | |
* For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter | |
* to items in conjunction with a tracking expression. | |
* | |
* * `variable in expression as alias_expression` � You can also provide an optional alias expression which will then store the | |
* intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message | |
* when a filter is active on the repeater, but the filtered result set is empty. | |
* | |
* For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after | |
* the items have been processed through the filter. | |
* | |
* @example | |
* This example initializes the scope to a list of names and | |
* then uses `ngRepeat` to display every person: | |

/** | |
* @ngdoc directive | |
* @name ngShow | |
* | |
* @description | |
* The `ngShow` directive shows or hides the given HTML element based on the expression | |
* provided to the `ngShow` attribute. The element is shown or hidden by removing or adding | |
* the `.ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined | |
* in AngularJS and sets the display style to none (using an !important flag). | |
* For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}). | |
* | |
* ```html | |
* <!-- when $scope.myValue is truthy (element is visible) --> | |
* <div ng-show="myValue"></div> | |
* | |
* <!-- when $scope.myValue is falsy (element is hidden) --> | |
* <div ng-show="myValue" class="ng-hide"></div> | |
* ``` | |
* | |
* When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added to the class | |
* attribute on the element causing it to become hidden. When truthy, the `.ng-hide` CSS class is removed | |
* from the element causing the element not to appear hidden. | |
* | |
* ## Why is !important used? | |
* | |
* You may be wondering why !important is used for the `.ng-hide` CSS class. This is because the `.ng-hide` selector | |
* can be easily overridden by heavier selectors. For example, something as simple | |
* as changing the display style on a HTML list item would make hidden elements appear visible. | |
* This also becomes a bigger issue when dealing with CSS frameworks. | |
* | |
* By using !important, the show and hide behavior will work as expected despite any clash between CSS selector | |
* specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the | |
* styling to change how to hide an element then it is just a matter of using !important in their own CSS code. | |
* | |
* ### Overriding `.ng-hide` | |
* | |
* By default, the `.ng-hide` class will style the element with `display: none!important`. If you wish to change | |
* the hide behavior with ngShow/ngHide then this can be achieved by restating the styles for the `.ng-hide` | |
* class in CSS: | |
* | |
* ```css | |
* .ng-hide { | |
* /* this is just another form of hiding an element */ | |
* display: block!important; | |
* position: absolute; | |
* top: -9999px; | |
* left: -9999px; | |
* } | |
* ``` | |
* | |
* By default you don't need to override in CSS anything and the animations will work around the display style. | |
* | |
* ## A note about animations with `ngShow` | |
* | |
* Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression | |
* is true and false. This system works like the animation system present with ngClass except that | |
* you must also include the !important flag to override the display property | |
* so that you can perform an animation when the element is hidden during the time of the animation. | |
* | |
* ```css | |
* // | |
* //a working example can be found at the bottom of this page | |
* // | |
* .my-element.ng-hide-add, .my-element.ng-hide-remove { | |
* /* this is required as of 1.3x to properly | |
* apply all styling in a show/hide animation */ | |
* transition: 0s linear all; | |
* } | |
* | |
* .my-element.ng-hide-add-active, | |
* .my-element.ng-hide-remove-active { | |
* /* the transition is defined in the active class */ | |
* transition: 1s linear all; | |
* } | |
* | |
* .my-element.ng-hide-add { ... } | |
* .my-element.ng-hide-add.ng-hide-add-active { ... } | |
* .my-element.ng-hide-remove { ... } | |
* .my-element.ng-hide-remove.ng-hide-remove-active { ... } | |
* ``` | |
* | |
* Keep in mind that, as of AngularJS version 1.3.0-beta.11, there is no need to change the display | |
* property to block during animation states--ngAnimate will handle the style toggling automatically for you. | |
* | |
* @animations | |
* addClass: `.ng-hide` - happens after the `ngShow` expression evaluates to a truthy value and the just before contents are set to visible | |
* removeClass: `.ng-hide` - happens after the `ngShow` expression evaluates to a non truthy value and just before the contents are set to hidden | |
* | |
* @element ANY | |
* @param {expression} ngShow If the {@link guide/expression expression} is truthy | |
* then the element is shown or hidden respectively. | |

* @description | |
* The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression. | |
* Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location | |
* as specified in the template. | |
* | |
* The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it | |
* from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element | |
* matches the value obtained from the evaluated expression. In other words, you define a container element | |
* (where you place the directive), place an expression on the **`on="..."` attribute** | |
* (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place | |
* a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on | |
* expression is evaluated. If a matching expression is not found via a when attribute then an element with the default | |
* attribute is displayed. | |
* | |
* <div class="alert alert-info"> | |
* Be aware that the attribute values to match against cannot be expressions. They are interpreted | |
* as literal string values to match against. | |
* For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the | |
* value of the expression `$scope.someVal`. | |
* </div> | |
* @animations | |
* enter - happens after the ngSwitch contents change and the matched child element is placed inside the container | |
* leave - happens just after the ngSwitch contents change and just before the former contents are removed from the DOM | |
* | |
* @usage | |
* | |
* ``` | |
* <ANY ng-switch="expression"> | |
* <ANY ng-switch-when="matchValue1">...</ANY> | |
* <ANY ng-switch-when="matchValue2">...</ANY> | |
* <ANY ng-switch-default>...</ANY> | |

* * `ngSwitchWhen`: the case statement to match against. If match then this | |
* case will be displayed. If the same match appears multiple times, all the | |
* elements will be displayed. | |
* * `ngSwitchDefault`: the default case when no other case match. If there | |
* are multiple default cases, all of them will be displayed when no other | |

* @ngdoc directive | |

* | |
* @description | |
* HTML `SELECT` element with angular data-binding. | |
* | |
* # `ngOptions` | |
* | |
* The `ngOptions` attribute can be used to dynamically generate a list of `<option>` | |
* elements for the `<select>` element using the array or object obtained by evaluating the | |
* `ngOptions` comprehension expression. | |
* | |
* In many cases, `ngRepeat` can be used on `<option>` elements instead of `ngOptions` to achieve a | |
* similar result. However, `ngOptions` provides some benefits such as reducing memory and | |
* increasing speed by not creating a new scope for each repeated instance, as well as providing | |
* more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the | |
* comprehension expression. `ngOptions` should be used when the `<select>` model needs to be bound | |
* to a non-string value. This is because an option element can only be bound to string values at | |
* present. | |
* | |
* When an item in the `<select>` menu is selected, the array element or object property | |
* represented by the selected option will be bound to the model identified by the `ngModel` | |
* directive. | |
* | |
* Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can | |
* be nested into the `<select>` element. This element will then represent the `null` or "not selected" | |
* option. See example below for demonstration. | |
* | |
* <div class="alert alert-warning"> | |
* **Note:** `ngModel` compares by reference, not value. This is important when binding to an | |
* array of objects. See an example [in this jsfiddle](http://jsfiddle.net/qWzTb/). | |
* </div> | |
* | |
* ## `select` **`as`** | |
* | |
* Using `select` **`as`** will bind the result of the `select` expression to the model, but | |
* the value of the `<select>` and `<option>` html elements will be either the index (for array data sources) | |
* or property name (for object data sources) of the value within the collection. If a **`track by`** expression | |
* is used, the result of that expression will be set as the value of the `option` and `select` elements. | |
* | |
* | |
* ### `select` **`as`** and **`track by`** | |
* | |
* <div class="alert alert-warning"> | |
* Do not use `select` **`as`** and **`track by`** in the same expression. They are not designed to work together. | |
* </div> | |
* | |
* Consider the following example: | |
* | |
* ```html | |
* <select ng-options="item.subItem as item.label for item in values track by item.id" ng-model="selected"> | |
* ``` | |
* | |
* ```js | |
* $scope.values = [{ | |
* id: 1, | |
* label: 'aLabel', | |
* subItem: { name: 'aSubItem' } | |
* }, { | |
* id: 2, | |
* label: 'bLabel', | |
* subItem: { name: 'bSubItem' } | |
* }]; | |
* | |
* $scope.selected = { name: 'aSubItem' }; | |
* ``` | |
* | |
* With the purpose of preserving the selection, the **`track by`** expression is always applied to the element | |
* of the data source (to `item` in this example). To calculate whether an element is selected, we do the | |
* following: | |
* | |
* 1. Apply **`track by`** to the elements in the array. In the example: `[1, 2]` | |
* 2. Apply **`track by`** to the already selected value in `ngModel`. | |
* In the example: this is not possible as **`track by`** refers to `item.id`, but the selected | |
* value from `ngModel` is `{name: 'aSubItem'}`, so the **`track by`** expression is applied to | |
* a wrong object, the selected element can't be found, `<select>` is always reset to the "not | |
* selected" option. | |
* | |
* | |
* @param {string} ngModel Assignable angular expression to data-bind to. | |
* @param {string=} name Property name of the form under which the control is published. | |
* @param {string=} required The control is considered valid only if value is entered. | |
* @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to | |
* the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of | |
* `required` when you want to data-bind to the `required` attribute. | |
* @param {comprehension_expression=} ngOptions in one of the following forms: | |
* | |
* * for array data sources: | |
* * `label` **`for`** `value` **`in`** `array` | |
* * `select` **`as`** `label` **`for`** `value` **`in`** `array` | |
* * `label` **`group by`** `group` **`for`** `value` **`in`** `array` | |
* * `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr` | |
* * `label` **`for`** `value` **`in`** `array` | orderBy:`orderexpr` **`track by`** `trackexpr` | |
* (for including a filter with `track by`) | |
* * for object data sources: | |
* * `label` **`for (`**`key` **`,`** `value`**`) in`** `object` | |
* * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object` | |
* * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object` | |
* * `select` **`as`** `label` **`group by`** `group` | |
* **`for` `(`**`key`**`,`** `value`**`) in`** `object` | |
* | |
* Where: | |
* | |
* * `array` / `object`: an expression which evaluates to an array / object to iterate over. | |
* * `value`: local variable which will refer to each item in the `array` or each property value | |
* of `object` during iteration. | |
* * `key`: local variable which will refer to a property name in `object` during iteration. | |
* * `label`: The result of this expression will be the label for `<option>` element. The | |
* `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`). | |
* * `select`: The result of this expression will be bound to the model of the parent `<select>` | |
* element. If not specified, `select` expression will default to `value`. | |
* * `group`: The result of this expression will be used to group options using the `<optgroup>` | |
* DOM element. | |
* * `trackexpr`: Used when working with an array of objects. The result of this expression will be | |
* used to identify the objects in the array. The `trackexpr` will most likely refer to the | |
* `value` variable (e.g. `value.propertyName`). With this the selection is preserved | |
* even when the options are recreated (e.g. reloaded from the server). | |
