| * @ngdoc function |
| * @name angular.element |
| * @function |
| * |
| * @description |
| * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element. |
| * `angular.element` can be either an alias for [jQuery](http://api.jquery.com/jQuery/) function, if |
| * jQuery is available, or a function that wraps the element or string in Angular's jQuery lite |
| * implementation (commonly referred to as jqLite). |
| * |
| * Real jQuery always takes precedence over jqLite, provided it was loaded before `DOMContentLoaded` |
| * event fired. |
| * |
| * jqLite is a tiny, API-compatible subset of jQuery that allows |
| * Angular to manipulate the DOM. jqLite implements only the most commonly needed functionality |
| * within a very small footprint, so only a subset of the jQuery API - methods, arguments and |
| * invocation styles - are supported. |
| * |
| * Note: All element references in Angular are always wrapped with jQuery or jqLite; they are never |
| * raw DOM references. |
| * |
| * ## Angular's jQuery lite provides the following methods: |
| * |
| * - [addClass()](http://api.jquery.com/addClass/) |
| * - [after()](http://api.jquery.com/after/) |
| * - [append()](http://api.jquery.com/append/) |
| * - [attr()](http://api.jquery.com/attr/) |
| * - [bind()](http://api.jquery.com/bind/) |
| * - [children()](http://api.jquery.com/children/) |
| * - [clone()](http://api.jquery.com/clone/) |
| * - [contents()](http://api.jquery.com/contents/) |
| * - [css()](http://api.jquery.com/css/) |
| * - [data()](http://api.jquery.com/data/) |
| * - [eq()](http://api.jquery.com/eq/) |
| * - [find()](http://api.jquery.com/find/) - Limited to lookups by tag name. |
| * - [hasClass()](http://api.jquery.com/hasClass/) |
| * - [html()](http://api.jquery.com/html/) |
| * - [next()](http://api.jquery.com/next/) |
| * - [parent()](http://api.jquery.com/parent/) |
| * - [prepend()](http://api.jquery.com/prepend/) |
| * - [prop()](http://api.jquery.com/prop/) |
| * - [ready()](http://api.jquery.com/ready/) |
| * - [remove()](http://api.jquery.com/remove/) |
| * - [removeAttr()](http://api.jquery.com/removeAttr/) |
| * - [removeClass()](http://api.jquery.com/removeClass/) |
| * - [removeData()](http://api.jquery.com/removeData/) |
| * - [replaceWith()](http://api.jquery.com/replaceWith/) |
| * - [text()](http://api.jquery.com/text/) |
| * - [toggleClass()](http://api.jquery.com/toggleClass/) |
| * - [triggerHandler()](http://api.jquery.com/triggerHandler/) - Doesn't pass native event objects to handlers. |
| * - [unbind()](http://api.jquery.com/unbind/) |
| * - [val()](http://api.jquery.com/val/) |
| * - [wrap()](http://api.jquery.com/wrap/) |
| * |
| * ## In addtion to the above, Angular provides additional methods to both jQuery and jQuery lite: |
| * |
| * - `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 api/ng.$rootScope.Scope scope} of the current |
| * element or its parent. |
| * - `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. |

| * `$injector` is used to retrieve object instances as defined by |
| * {@link AUTO.$provide provider}, instantiate types, invoke methods, |
| * and load modules. |

| * # Injection Function Annotation |
| * |
| * JavaScript does not have annotations, and annotations are needed for dependency injection. The |
| * following ways are all valid way of annotating function with injection arguments and are equivalent. |
| * |
| * <pre> |
| * // inferred (only works if code not minified/obfuscated) |
| * $inject.invoke(function(serviceA){}); |
| * |
| * // annotated |
| * function explicit(serviceA) {}; |
| * explicit.$inject = ['serviceA']; |
| * $inject.invoke(explicit); |
| * |
| * // inline |
| * $inject.invoke(['serviceA', function(serviceA){}]); |
| * </pre> |
| * |
| * ## Inference |
| * |
| * In JavaScript calling `toString()` on a function returns the function definition. The definition can then be |
| * parsed and the function arguments can be extracted. *NOTE:* This does not work with minification, and obfuscation |
| * tools since these tools change the argument names. |
| * |
| * ## `$inject` Annotation |
| * By adding a `$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 AUTO.$injector#annotate |
| * @methodOf AUTO.$injector |
| * |
| * @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. |
| * <pre> |
| * // Given |
| * function MyController($scope, $route) { |
| * // ... |
| * } |
| * |
| * // Then |
| * expect(injector.annotate(MyController)).toEqual(['$scope', '$route']); |
| * </pre> |
| * |
| * This method does not work with code minfication / obfuscation. For this reason the following annotation strategies |
| * are supported. |
| * |
| * # The `$inject` property |
| * |
| * If a function has an `$inject` property and its value is an array of strings, then the strings represent names of |
| * services to be injected into the function. |
| * <pre> |
| * // Given |
| * var MyController = function(obfuscatedScope, obfuscatedRoute) { |
| * // ... |
| * } |
| * // Define function dependencies |
| * MyController.$inject = ['$scope', '$route']; |
| * |
| * // Then |
| * expect(injector.annotate(MyController)).toEqual(['$scope', '$route']); |
| * </pre> |
| * |
| * # The array notation |
| * |
| * It is often desirable to inline Injected functions and that's when setting the `$inject` property is very |
| * inconvenient. In these situations using the array notation to specify the dependencies in a way that survives |
| * minification is a better choice: |
| * |
| * <pre> |
| * // We wish to write this (not minification / obfuscation safe) |
| * injector.invoke(function($compile, $rootScope) { |
| * // ... |
| * }); |
| * |
| * // We are forced to write break inlining |
| * var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) { |
| * // ... |
| * }; |
| * tmpFn.$inject = ['$compile', '$rootScope']; |
| * injector.invoke(tempFn); |
| * |
| * // 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']); |
| * </pre> |
| * |
| * @param {function|Array.<string|Function>} fn Function for which dependent service names need to be retrieved as described |
| * above. |
| * |
| * @returns {Array.<string>} The names of the services which the function requires. |

| * Compiles a piece of HTML string or DOM into a template and produces a template function, which |

| * |
| * The compilation is a process of walking the DOM tree and trying to match DOM elements to |
| * {@link ng.$compileProvider#directive directives}. For each match it |
| * executes corresponding template function and collects the |
| * instance functions into a single template function which is then returned. |
| * |
| * The template function can then be used once to produce the view or as it is the case with |
| * {@link ng.directive:ngRepeat repeater} many-times, in which |
| * case each call results in a view that is a DOM clone of the original template. |

| * @param {function(angular.Scope[, cloneAttachFn]} transclude function available to directives. |
| * @param {number} maxPriority only apply directives lower then given priority (Only effects the |
| * root element(s), not their children) |
| * @returns {function(scope[, cloneAttachFn])} 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. |
| * |
| * 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. |
| * <pre> |
| * var element = $compile('<p>{{total}}</p>')(scope); |
| * </pre> |
| * |
| * - 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: |
| * <pre> |
| * var templateHTML = angular.element('<p>{{total}}</p>'), |
| * scope = ....; |
| * |
| * var clonedElement = $compile(templateHTML)(scope, function(clonedElement, scope) { |
| * //attach the clone to DOM document at the right place |
| * }); |
| * |
| * //now we have reference to the cloned DOM via `clone` |
| * </pre> |
| * |
| * |
| * For information on how the compiler works, see the |
| * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide. |

| * |
| * @description |
| * A promise/deferred implementation inspired by [Kris Kowal's Q](https://github.com/kriskowal/q). |
| * |
| * [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. |
| * |
| * <pre> |
| * // for the purpose of this example let's assume that variables `$q` and `scope` are |
| * // available in the current lexical scope (they could have been injected or passed in). |
| * |
| * function asyncGreet(name) { |
| * var deferred = $q.defer(); |
| * |
| * setTimeout(function() { |
| * // since this fn executes async in a future turn of the event loop, we need to wrap |
| * // our code into an $apply call so that the model changes are properly observed. |
| * scope.$apply(function() { |
| * 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); |
| * }); |
| * </pre> |
| * |
| * 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](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 `$q.defer()`. |
| * |
| * The purpose of the deferred object is to expose the associated Promise instance as well as APIs |
| * that can be used for signaling the successful or unsuccessful completion of the task. |
| * |
| * **Methods** |
| * |
| * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection |
| * constructed via `$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`. |
| * |
| * **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)` – regardless of when the promise was or will be resolved |
| * or rejected 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. |
| * |
| * This method *returns a new promise* which is resolved or rejected via the return value of the |
| * `successCallback` or `errorCallback`. |
| * |
| * |
| * # Chaining promises |
| * |
| * Because calling `then` api of a promise returns a new derived promise, it is easily possible |
| * to create a chain of promises: |
| * |
| * <pre> |
| * 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 |
| * </pre> |
| * |
| * 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 three 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 promises are recognized by the templating engine in angular, which means that in templates |
| * you can treat promises attached to a scope as if they were the resulting values. |
| * - Q has many more features that $q, but that comes at a cost of bytes. $q is tiny, but contains |
| * all the important functionality needed for common async tasks. |
| * |
| * # Testing |
| * |
| * <pre> |
| * it('should simulate promise', inject(function($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); |
| * }); |

| * `reject`. |

| * DESIGN NOTES |
| * |
| * The design decisions behind the scope ware 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 from speed as well as memory: |
| * - no closures, instead ups 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 begging (shift) instead of at the end (push) |

| * @methodOf ng.$rootScope.Scope |
| * @function |
| * |
| * @description |
| * Registers a `listener` callback to be executed whenever the `watchExpression` changes. |
| * |
| * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest $digest()} and |
| * should return the value which will be watched. (Since {@link ng.$rootScope.Scope#$digest $digest()} |
| * reruns when it detects changes the `watchExpression` can execute multiple times per |
| * {@link ng.$rootScope.Scope#$digest $digest()} and should be idempotent.) |
| * - The `listener` is called only when the value from the current `watchExpression` and the |
| * previous call to `watchExpression` are not equal (with the exception of the initial run, |
| * see below). The inequality is determined according to |
| * {@link angular.equals} function. To save the value of the object for later comparison, the |
| * {@link angular.copy} function is used. It also means that watching complex options will |
| * have adverse memory and performance implications. |
| * - The watch `listener` may change the model, which may trigger other `listener`s to fire. This |
| * is achieved by rerunning the watchers until no changes are detected. The rerun iteration |
| * limit is 10 to prevent an infinite loop deadlock. |
| * |
| * |
| * If you want to be notified whenever {@link ng.$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 |
| * <pre> |
| // let's assume that scope was dependency injected as the $rootScope |
| var scope = $rootScope; |
| scope.name = 'misko'; |
| scope.counter = 0; |
| |

| * |
| * @description |
| * The `$http` service is a core Angular service that facilitates communication with the remote |
| * HTTP servers via browser's {@link https://developer.mozilla.org/en/xmlhttprequest |
| * XMLHttpRequest} object or via {@link http://en.wikipedia.org/wiki/JSONP JSONP}. |
| * |
| * For unit testing applications that use `$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 $q service. While for simple usage patters this doesn't matter much, for advanced usage, |
| * it is important to familiarize yourself with these apis and guarantees they provide. |
| * |
| * |
| * # General usage |
| * The `$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`. |
| * |
| * <pre> |
| * $http({method: 'GET', url: '/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. |
| * }); |
| * </pre> |
| * |
| * Since the returned value of calling the $http function is a Promise object, 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 that falls in the [200, 300) range 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. |
| * |
| * # Shortcut methods |
| * |
| * Since all invocation of the $http service require definition of the http method and url and |
| * POST and PUT requests require response body/data to be provided as well, shortcut methods |
| * were created to simplify using the api: |
| * |
| * <pre> |
| * $http.get('/someUrl').success(successCallback); |
| * $http.post('/someUrl', data).success(successCallback); |
| * </pre> |
| * |
| * Complete list of shortcut methods: |
| * |
| * - {@link ng.$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} |
| * |
| * |
| * # 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: |
| * |
| * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): |
| * - `Accept: application/json, text/plain, * / *` |
| * - `X-Requested-With: XMLHttpRequest` |
| * - `$httpProvider.defaults.headers.post`: (header defaults for HTTP POST requests) |
| * - `Content-Type: application/json` |
| * - `$httpProvider.defaults.headers.put` (header defaults for HTTP PUT requests) |
| * - `Content-Type: application/json` |
| * |
| * To add or overwrite these defaults, simply add or remove a property from this configuration |
| * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object |
| * with name equal to the lower-cased http method name, e.g. |
| * `$httpProvider.defaults.headers.get['My-Header']='value'`. |
| * |
| * Additionally, the defaults can be set at runtime via the `$http.defaults` object in a similar |
| * fassion as described above. |
| * |
| * |
| * # Transforming Requests and Responses |
| * |
| * Both requests and responses can be transformed using transform functions. By default, Angular |
| * applies these transformations: |
| * |
| * Request transformations: |
| * |
| * - if the `data` property of the request config object contains an object, serialize it into |
| * JSON format. |
| * |
| * Response transformations: |
| * |
| * - if XSRF prefix is detected, strip it (see Security Considerations section below) |
| * - if json response is detected, deserialize it using a JSON parser |
| * |
| * To override these transformation locally, specify transform functions as `transformRequest` |
| * and/or `transformResponse` properties of the config object. To globally override the default |
| * transforms, override the `$httpProvider.defaults.transformRequest` and |
| * `$httpProvider.defaults.transformResponse` properties of the `$httpProvider`. |
| * |
| * |
| * # Caching |
| * |
| * To enable caching set the configuration property `cache` to `true`. When the cache is |
| * enabled, `$http` stores the response from the server in local cache. Next time the |
| * response is served from the cache without sending a request to the server. |
| * |
| * Note that even if the response is served from cache, delivery of the data is asynchronous in |
| * the same way that real requests are. |
| * |
| * If there are multiple GET requests for the same url that should be cached using the same |
| * cache, but the cache is not populated yet, only one request to the server will be made and |
| * the remaining requests will be fulfilled using the response for the first request. |
| * |
| * |
| * # Response interceptors |
| * |
| * Before you start creating interceptors, be sure to understand the |
| * {@link ng.$q $q and deferred/promise APIs}. |
| * |
| * For purposes of global error handling, authentication or any kind of synchronous or |
| * asynchronous preprocessing of received responses, it is desirable to be able to intercept |
| * responses for http requests before they are handed over to the application code that |
| * initiated these requests. The response interceptors leverage the {@link ng.$q |
| * promise apis} to fulfil this need for both synchronous and asynchronous preprocessing. |
| * |
| * The interceptors are service factories that are registered with the $httpProvider by |
| * adding them to the `$httpProvider.responseInterceptors` array. The factory is called and |
| * injected with dependencies (if specified) and returns the interceptor — a function that |
| * takes a {@link ng.$q promise} and returns the original or a new promise. |
| * |
| * <pre> |
| * // register the interceptor as a service |
| * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { |
| * return function(promise) { |
| * return promise.then(function(response) { |
| * // do something on success |
| * }, function(response) { |
| * // do something on error |
| * if (canRecover(response)) { |
| * return responseOrNewPromise |
| * } |
| * return $q.reject(response); |
| * }); |
| * } |
| * }); |
| * |
| * $httpProvider.responseInterceptors.push('myHttpInterceptor'); |
| * |
| * |
| * // register the interceptor via an anonymous factory |
| * $httpProvider.responseInterceptors.push(function($q, dependency1, dependency2) { |
| * return function(promise) { |
| * // same as above |
| * } |
| * }); |
| * </pre> |
| * |
| * |
| * # Security Considerations |
| * |
| * When designing web applications, consider security threats from: |
| * |
| * - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx |
| * JSON Vulnerability} |
| * - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} |
| * |
| * 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 {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx |
| * JSON Vulnerability} allows third party web-site to turn your JSON resource URL into |
| * {@link http://en.wikipedia.org/wiki/JSON#JSONP 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: |
| * <pre> |
| * ['one','two'] |
| * </pre> |
| * |
| * which is vulnerable to attack, your server can return: |
| * <pre> |
| * )]}', |
| * ['one','two'] |
| * </pre> |
| * |
| * Angular will strip the prefix, before processing the JSON. |
| * |
| * |
| * ## Cross Site Request Forgery (XSRF) Protection |
| * |
| * {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which |
| * an unauthorized site can gain your user's private data. Angular provides following mechanism |
| * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie |
| * called `XSRF-TOKEN` and sets it as the 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. |
| * |
| * To take advantage of this, your server needs to set a token in a JavaScript readable session |
| * cookie called `XSRF-TOKEN` on first HTTP GET request. On subsequent non-GET 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 read the token. The token must be |
| * unique for each user and must be verifiable by the server (to prevent the JavaScript making |
| * up its own tokens). We recommend that the token is a digest of your site's authentication |
| * cookie with {@link http://en.wikipedia.org/wiki/Rainbow_table salt for added security}. |
| * |
| * |
| * @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 representing HTTP headers to send to the server. |
| * - **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. |
| * - **transformResponse** – `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` – |
| * transform function or an array of such functions. The transform function takes the http |
| * response body and headers and returns its transformed (typically deserialized) version. |
| * - **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 $cacheFactory}, this cache will be used for |
| * caching. |
| * - **timeout** – `{number}` – timeout in milliseconds. |
| * - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the |
| * XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5 |
| * requests with credentials} for more information. |
| * |
| * @returns {HttpPromise} Returns a {@link ng.$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. |
| * |
| * @property {Array.<Object>} pendingRequests Array of config objects for currently pending |
| * requests. This is primarily meant to be used for debugging purposes. |

| * @name ng.filter:filter |
| * @function |
| * |
| * @description |
| * Selects a subset of items from `array` and returns it as a new array. |
| * |
| * Note: This function is used to augment the `Array` type in Angular expressions. See |
| * {@link ng.$filter} for more information about Angular arrays. |
| * |
| * @param {Array} array The source array. |
| * @param {string|Object|function()} expression The predicate to be used for selecting items from |
| * `array`. |
| * |
| * Can be one of: |
| * |
| * - `string`: Predicate that results in a substring match using the value of `expression` |
| * string. All strings or objects with string properties in `array` that contain this string |
| * will be returned. The predicate can be negated by prefixing the string with `!`. |
| * |
| * - `Object`: A pattern object can be used to filter specific properties on objects contained |
| * by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items |
| * which have property `name` containing "M" and property `phone` containing "1". A special |
| * property name `$` can be used (as in `{$:"text"}`) to accept a match against any |
| * property of the object. That's equivalent to the simple substring match with a `string` |
| * as described above. |
| * |
| * - `function`: 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. |

| * |
| * @description |
| * Formats `date` to a string based on the requested `format`. |
| * |
| * `format` string can be composed of the following elements: |
| * |
| * * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010) |
| * * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10) |
| * * `'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) |
| * * `'a'`: am/pm marker |
| * * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-1200) |
| * |
| * `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) |
| * * `'fullDate'`: equivalent to `'EEEE, MMMM d,y'` for en_US locale |
| * (e.g. Friday, September 3, 2010) |
| * * `'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 quoted with single quotes (e.g. |
| * `"h 'in the morning'"`). In order to output single quote, use 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 it's |
| * 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. |
| * @returns {string} Formatted string or the input if input is not recognized as date/millis. |

| * Note: this function is used to augment the `Array` type in Angular expressions. See |
| * {@link ng.$filter} for more informaton about Angular arrays. |
| * |
| * @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 which evaluates to an object to order by, such as 'name' |
| * to sort by a property called 'name'. Optionally prefixed with `+` or `-` to control |
| * ascending or descending sort order (for example, +name or -name). |
| * - `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. |
| * |
| * @param {boolean=} reverse Reverse the order the array. |
| * @returns {Array} Sorted copy of the source array. |

| * - `ng-valid` Is set if the form is valid. |
| * - `ng-invalid` Is set if the form is invalid. |

| * |
| * # Submitting a form and preventing 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 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 ngSubmit or ngClick directives. This |
| * is because of the following form submission rules coming from the html spec: |
| * |
| * - If a form has only one input field then hitting enter in this field triggers form submit |
| * (`ngSubmit`) |
| * - if a form has 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`) |
| * |
| * @param {string=} name Name of the form. If specified, the form controller will be published into |
| * related scope, under this name. |

| * `NgModelController` provides API for the `ng-model` directive. The controller contains |
| * services for data-binding, validation, CSS update, value formatting and parsing. It |
| * specifically does not contain any logic which deals with DOM rendering or listening to |
| * DOM events. The `NgModelController` is meant to be extended by other directives where, the |
| * directive provides DOM manipulation and the `NgModelController` provides the data-binding. |
| * |
| * 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. |
| * |

| [contenteditable] { |
| border: 1px solid black; |
| background-color: white; |
| min-height: 20px; |
| } |
| |
| .ng-invalid { |
| border: 1px solid red; |
| } |
| |
| </file> |
| <file name="script.js"> |
| angular.module('customControl', []). |
| directive('contenteditable', function() { |
| return { |
| restrict: 'A', // only activate on element attribute |
| require: '?ngModel', // get a hold of NgModelController |
| link: function(scope, element, attrs, ngModel) { |
| if(!ngModel) return; // do nothing if no ng-model |
| |
| // Specify how UI should be updated |
| ngModel.$render = function() { |
| element.html(ngModel.$viewValue || ''); |
| }; |
| |
| // Listen for change events to enable binding |
| element.bind('blur keyup change', function() { |

| read(); // initialize |
| |
| // Write data to the model |

| * |
| * - binding the view into the model, which other directives such as `input`, `textarea` or `select` |

| * - setting related css class onto the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`), |
| * - register the control with parent {@link ng.directive:form form}. |
| * |
| * For basic examples, how to use `ngModel`, see: |

| * - {@link ng.directive:input input} |
| * - {@link ng.directive:input.text text} |
| * - {@link ng.directive:input.checkbox checkbox} |

| * @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. |
| * |
| * Once scenario in which the use of `ngBind` is prefered over `{{ expression }}` binding is when |
| * it's desirable to put bindings into template that 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. |

| /** |
| * @ngdoc directive |
| * @name ng.directive:ngCloak |
| * |
| * @description |
| * The `ngCloak` directive is used to prevent the Angular html template from being briefly |
| * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this |
| * directive to avoid the undesirable flicker effect caused by the html template display. |
| * |
| * The directive can be applied to the `<body>` element, but typically a fine-grained application is |
| * prefered in order to benefit from progressive rendering of the browser view. |
| * |
| * `ngCloak` works in cooperation with a css rule that is embedded within `angular.js` and |
| * `angular.min.js` files. Following is the css rule: |
| * |
| * <pre> |
| * [ng\:cloak], [ng-cloak], .ng-cloak { |
| * display: none; |
| * } |
| * </pre> |
| * |
| * When this css rule is loaded by the browser, all html elements (including their children) that |
| * are tagged with the `ng-cloak` directive are hidden. When Angular comes across this directive |
| * during the compilation of the template it deletes the `ngCloak` element attribute, which |
| * makes the compiled element visible. |
| * |
| * For the best result, `angular.js` script must be loaded in the head section of the html file; |
| * 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 `ngCloak` in addition to `ngCloak` directive as shown in the example below. |
| * |
| * @element ANY |
| * |
| * @example |
| <doc:example> |

| * @description |
| * The `ngController` directive assigns behavior to a scope. This is a key aspect of how angular |
| * supports the principles behind the Model-View-Controller design pattern. |
| * |
| * MVC components in angular: |
| * |
| * * Model — The Model is data in scope properties; scopes are attached to the DOM. |
| * * View — The template (HTML with data bindings) is rendered into the View. |
| * * Controller — The `ngController` directive specifies a Controller class; the class has |
| * methods that typically express the business logic behind the application. |
| * |
| * Note that an alternative way to define controllers is via the `{@link ng.$route}` |
| * service. |
| * |
| * @element ANY |
| * @scope |
| * @param {expression} ngController Name of a globally accessible constructor function or an |
| * {@link guide/expression expression} that on the current scope evaluates to a |
| * constructor function. |
| * |
| * @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. Notice that the scope becomes the `this` for the |
| * controller's instance. This allows for easy access to the view data from the controller. Also |
| * notice that any changes to the data are automatically reflected in the View without the need |
| * for a manual update. |

| /** |
| * @ngdoc directive |
| * @name ng.directive:ngPluralize |
| * @restrict EA |
| * |
| * @description |
| * # Overview |
| * `ngPluralize` is a directive that displays messages according to en-US localization rules. |
| * These rules are bundled with angular.js and the rules can be overridden |
| * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive |
| * by specifying the mappings between |
| * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html |
| * plural categories} and the strings to be displayed. |
| * |
| * # Plural categories and explicit number rules |
| * There are two |
| * {@link http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html |
| * plural categories} in Angular's default en-US locale: "one" and "other". |
| * |
| * While a pural 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. You will see the use of plural categories |
| * and explicit number rules throughout later parts 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 so that Angular |
| * can interpret it correctly. |
| * |
| * The following example shows how to configure ngPluralize: |
| * |
| * <pre> |
| * <ng-pluralize count="personCount" |
| when="{'0': 'Nobody is viewing.', |
| * 'one': '1 person is viewing.', |
| * 'other': '{} people are viewing.'}"> |
| * </ng-pluralize> |
| *</pre> |
| * |
| * 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: |
| * |
| * <pre> |
| * <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> |
| * </pre> |
| * |
| * 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, Marry 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 bounded to. |
| * @param {string} when The mapping between plural category to its correspoding strings. |
| * @param {number=} offset Offset to deduct from the total number. |
| * |
| * @example |
| <doc:example> |
| <doc:source> |
| <script> |
| function Ctrl($scope) { |
| $scope.person1 = 'Igor'; |

| Person 2:<input type="text" ng-model="person2" value="Misko" /><br/> |
| Number of People:<input type="text" ng-model="personCount" value="1" /><br/> |
| |
| <!--- Example with simple pluralization rules for en locale ---> |
| Without Offset: |

| * # `ngOptions` |
| * |
| * Optionally `ngOptions` attribute can be used to dynamically generate a list of `<option>` |
| * elements for a `<select>` element using an array or an object obtained by evaluating the |
| * `ngOptions` expression. |
| *˝˝ |
| * When an item in the select menu is select, the value of array element or object property |
| * represented by the selected option will be bound to the model identified by the `ngModel` |
| * directive of the parent select element. |
| * |
| * 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 `null` or "not selected" |
| * option. See example below for demonstration. |
| * |
| * Note: `ngOptions` provides iterator facility for `<option>` element which should be used instead |
| * of {@link ng.directive:ngRepeat ngRepeat} when you want the |
| * `select` model to be bound to a non-string value. This is because an option element can currently |
| * be bound to string values only. |
| * |
| * @param {string} name assignable expression to data-bind to. |
| * @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` |
| * * `select` **`as`** `label` **`group by`** `group` **`for`** `value` **`in`** `array` |
| * * 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. |
