| * # ngAnimate |
| * |
| * The `ngAnimate` module provides support for JavaScript, CSS3 transition and CSS3 keyframe animation hooks within existing core and custom directives. |
| * |
| * {@installModule animate} |
| * |
| * <div doc-module-components="ngAnimate"></div> |
| * |
| * # Usage |
| * |
| * To see animations in action, all that is required is to define the appropriate CSS classes |
| * or to register a JavaScript animation via the myModule.animation() function. The directives that support animation automatically are: |
| * `ngRepeat`, `ngInclude`, `ngIf`, `ngSwitch`, `ngShow`, `ngHide`, `ngView` and `ngClass`. Custom directives can take advantage of animation |
| * by using the `$animate` service. |
| * |
| * Below is a more detailed breakdown of the supported animation events provided by pre-existing ng directives: |
| * |
| * | Directive | Supported Animations | |
| * |---------------------------------------------------------- |----------------------------------------------------| |
| * | {@link ng.directive:ngRepeat#usage_animations ngRepeat} | enter, leave and move | |
| * | {@link ngRoute.directive:ngView#usage_animations ngView} | enter and leave | |
| * | {@link ng.directive:ngInclude#usage_animations ngInclude} | enter and leave | |
| * | {@link ng.directive:ngSwitch#usage_animations ngSwitch} | enter and leave | |
| * | {@link ng.directive:ngIf#usage_animations ngIf} | enter and leave | |
| * | {@link ng.directive:ngClass#usage_animations ngClass} | add and remove | |
| * | {@link ng.directive:ngShow#usage_animations ngShow & ngHide} | add and remove (the ng-hide class value) | |
| * |
| * You can find out more information about animations upon visiting each directive page. |
| * |
| * Below is an example of how to apply animations to a directive that supports animation hooks: |
| * |
| * <pre> |
| * <style type="text/css"> |
| * .slide.ng-enter, .slide.ng-leave { |
| * -webkit-transition:0.5s linear all; |
| * transition:0.5s linear all; |
| * } |
| * |
| * .slide.ng-enter { } /* starting animations for enter */ |
| * .slide.ng-enter-active { } /* terminal animations for enter */ |
| * .slide.ng-leave { } /* starting animations for leave */ |
| * .slide.ng-leave-active { } /* terminal animations for leave */ |
| * </style> |
| * |
| * <!-- |
| * the animate service will automatically add .ng-enter and .ng-leave to the element |
| * to trigger the CSS transition/animations |
| * --> |
| * <ANY class="slide" ng-include="..."></ANY> |
| * </pre> |
| * |
| * Keep in mind that if an animation is running, any child elements cannot be animated until the parent element's |
| * animation has completed. |
| * |
| * <h2>CSS-defined Animations</h2> |
| * The animate service will automatically apply two CSS classes to the animated element and these two CSS classes |
| * are designed to contain the start and end CSS styling. Both CSS transitions and keyframe animations are supported |
| * and can be used to play along with this naming structure. |
| * |
| * The following code below demonstrates how to perform animations using **CSS transitions** with Angular: |
| * |
| * <pre> |
| * <style type="text/css"> |
| * /* |
| * The animate class is apart of the element and the ng-enter class |
| * is attached to the element once the enter animation event is triggered |
| * */ |
| * .reveal-animation.ng-enter { |
| * -webkit-transition: 1s linear all; /* Safari/Chrome */ |
| * transition: 1s linear all; /* All other modern browsers and IE10+ */ |
| * |
| * /* The animation preparation code */ |
| * opacity: 0; |
| * } |
| * |
| * /* |
| * Keep in mind that you want to combine both CSS |
| * classes together to avoid any CSS-specificity |
| * conflicts |
| * */ |
| * .reveal-animation.ng-enter.ng-enter-active { |
| * /* The animation code itself */ |
| * opacity: 1; |
| * } |
| * </style> |
| * |
| * <div class="view-container"> |
| * <div ng-view class="reveal-animation"></div> |
| * </div> |
| * </pre> |
| * |
| * The following code below demonstrates how to perform animations using **CSS animations** with Angular: |
| * |
| * <pre> |
| * <style type="text/css"> |
| * .reveal-animation.ng-enter { |
| * -webkit-animation: enter_sequence 1s linear; /* Safari/Chrome */ |
| * animation: enter_sequence 1s linear; /* IE10+ and Future Browsers */ |
| * } |
| * @-webkit-keyframes enter_sequence { |
| * from { opacity:0; } |
| * to { opacity:1; } |
| * } |
| * @keyframes enter_sequence { |
| * from { opacity:0; } |
| * to { opacity:1; } |
| * } |
| * </style> |
| * |
| * <div class="view-container"> |
| * <div ng-view class="reveal-animation"></div> |
| * </div> |
| * </pre> |
| * |
| * Both CSS3 animations and transitions can be used together and the animate service will figure out the correct duration and delay timing. |
| * |
| * Upon DOM mutation, the event class is added first (something like `ng-enter`), then the browser prepares itself to add |
| * the active class (in this case `ng-enter-active`) which then triggers the animation. The animation module will automatically |
| * detect the CSS code to determine when the animation ends. Once the animation is over then both CSS classes will be |
| * removed from the DOM. If a browser does not support CSS transitions or CSS animations then the animation will start and end |
| * immediately resulting in a DOM element that is at its final state. This final state is when the DOM element |
| * has no CSS transition/animation classes applied to it. |
| * |
| * <h3>CSS Staggering Animations</h3> |
| * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a |
| * curtain-like effect. The ngAnimate module, as of 1.2.0, supports staggering animations and the stagger effect can be |
| * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for |
| * the animation. The style property expected within the stagger class can either be a **transition-delay** or an |
| * **animation-delay** property (or both if your animation contains both transitions and keyframe animations). |
| * |
| * <pre> |
| * .my-animation.ng-enter { |
| * /* standard transition code */ |
| * -webkit-transition: 1s linear all; |
| * transition: 1s linear all; |
| * opacity:0; |
| * } |
| * .my-animation.ng-enter-stagger { |
| * /* this will have a 100ms delay between each successive leave animation */ |
| * -webkit-transition-delay: 0.1s; |
| * transition-delay: 0.1s; |
| * |
| * /* in case the stagger doesn't work then these two values |
| * must be set to 0 to avoid an accidental CSS inheritance */ |
| * -webkit-transition-duration: 0s; |
| * transition-duration: 0s; |
| * } |
| * .my-animation.ng-enter.ng-enter-active { |
| * /* standard transition styles */ |
| * opacity:1; |
| * } |
| * </pre> |
| * |
| * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations |
| * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this |
| * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation |
| * will also be reset if more than 10ms has passed after the last animation has been fired. |
| * |
| * The following code will issue the **ng-leave-stagger** event on the element provided: |
| * |
| * <pre> |
| * var kids = parent.children(); |
| * |
| * $animate.leave(kids[0]); //stagger index=0 |
| * $animate.leave(kids[1]); //stagger index=1 |
| * $animate.leave(kids[2]); //stagger index=2 |
| * $animate.leave(kids[3]); //stagger index=3 |
| * $animate.leave(kids[4]); //stagger index=4 |
| * |
| * $timeout(function() { |
| * //stagger has reset itself |
| * $animate.leave(kids[5]); //stagger index=0 |
| * $animate.leave(kids[6]); //stagger index=1 |
| * }, 100, false); |
| * </pre> |
| * |
| * Stagger animations are currently only supported within CSS-defined animations. |
| * |
| * <h2>JavaScript-defined Animations</h2> |
| * In the event that you do not want to use CSS3 transitions or CSS3 animations or if you wish to offer animations on browsers that do not |
| * yet support CSS transitions/animations, then you can make use of JavaScript animations defined inside of your AngularJS module. |
| * |
| * <pre> |
| * //!annotate="YourApp" Your AngularJS Module|Replace this or ngModule with the module that you used to define your application. |
| * var ngModule = angular.module('YourApp', ['ngAnimate']); |
| * ngModule.animation('.my-crazy-animation', function() { |
| * return { |
| * enter: function(element, done) { |
| * //run the animation here and call done when the animation is complete |
| * return function(cancelled) { |
| * //this (optional) function will be called when the animation |
| * //completes or when the animation is cancelled (the cancelled |
| * //flag will be set to true if cancelled). |
| * }; |
| * }, |
| * leave: function(element, done) { }, |
| * move: function(element, done) { }, |
| * |
| * //animation that can be triggered before the class is added |
| * beforeAddClass: function(element, className, done) { }, |
| * |
| * //animation that can be triggered after the class is added |
| * addClass: function(element, className, done) { }, |
| * |
| * //animation that can be triggered before the class is removed |
| * beforeRemoveClass: function(element, className, done) { }, |
| * |
| * //animation that can be triggered after the class is removed |
| * removeClass: function(element, className, done) { } |
| * }; |
| * }); |
| * </pre> |
| * |
| * JavaScript-defined animations are created with a CSS-like class selector and a collection of events which are set to run |
| * a javascript callback function. When an animation is triggered, $animate will look for a matching animation which fits |
| * the element's CSS class attribute value and then run the matching animation event function (if found). |
| * In other words, if the CSS classes present on the animated element match any of the JavaScript animations then the callback function will |
| * be executed. It should be also noted that only simple, single class selectors are allowed (compound class selectors are not supported). |
| * |
| * Within a JavaScript animation, an object containing various event callback animation functions is expected to be returned. |
| * As explained above, these callbacks are triggered based on the animation event. Therefore if an enter animation is run, |
| * and the JavaScript animation is found, then the enter callback will handle that animation (in addition to the CSS keyframe animation |
| * or transition code that is defined via a stylesheet). |
