|
|
* The `$animateCss` service is a useful utility to trigger customized CSS-based transitions/keyframes
|
||
|
|
* from a JavaScript-based animation or directly from a directive. The purpose of `$animateCss` is NOT
|
||
|
|
* to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or
|
||
|
|
* directives to create more complex animations that can be purely driven using CSS code.
|
||
|
|
*
|
||
|
|
* Note that only browsers that support CSS transitions and/or keyframe animations are capable of
|
||
|
|
* rendering animations triggered via `$animateCss` (bad news for IE9 and lower).
|
||
|
|
*
|
||
|
|
* ## Usage
|
||
|
|
* Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that
|
||
|
|
* is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however,
|
||
|
|
* any automatic control over cancelling animations and/or preventing animations from being run on
|
||
|
|
* child elements will not be handled by Angular. For this to work as expected, please use `$animate` to
|
||
|
|
* trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger
|
||
|
|
* the CSS animation.
|
||
|
|
*
|
||
|
|
* The example below shows how we can create a folding animation on an element using `ng-if`:
|
||
|
|
*
|
||
|
|
* ```html
|
||
|
|
* <!-- notice the `fold-animation` CSS class -->
|
||
|
|
* <div ng-if="onOff" class="fold-animation">
|
||
|
|
* This element will go BOOM
|
||
|
|
* </div>
|
||
|
|
* <button ng-click="onOff=true">Fold In</button>
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Now we create the **JavaScript animation** that will trigger the CSS transition:
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
|
||
|
|
* return {
|
||
|
|
* enter: function(element, doneFn) {
|
||
|
|
* var height = element[0].offsetHeight;
|
||
|
|
* return $animateCss(element, {
|
||
|
|
* from: { height:'0px' },
|
||
|
|
* to: { height:height + 'px' },
|
||
|
|
* duration: 1 // one second
|
||
|
|
* });
|
||
|
|
* }
|
||
|
|
* }
|
||
|
|
* }]);
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* ## More Advanced Uses
|
||
|
|
*
|
||
|
|
* `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks
|
||
|
|
* like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code.
|
||
|
|
*
|
||
|
|
* This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation,
|
||
|
|
* applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with
|
||
|
|
* `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order
|
||
|
|
* to provide a working animation that will run in CSS.
|
||
|
|
*
|
||
|
|
* The example below showcases a more advanced version of the `.fold-animation` from the example above:
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
|
||
|
|
* return {
|
||
|
|
* enter: function(element, doneFn) {
|
||
|
|
* var height = element[0].offsetHeight;
|
||
|
|
* return $animateCss(element, {
|
||
|
|
* addClass: 'red large-text pulse-twice',
|
||
|
|
* easing: 'ease-out',
|
||
|
|
* from: { height:'0px' },
|
||
|
|
* to: { height:height + 'px' },
|
||
|
|
* duration: 1 // one second
|
||
|
|
* });
|
||
|
|
* }
|
||
|
|
* }
|
||
|
|
* }]);
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Since we're adding/removing CSS classes then the CSS transition will also pick those up:
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* /* since a hardcoded duration value of 1 was provided in the JavaScript animation code,
|
||
|
|
* the CSS classes below will be transitioned despite them being defined as regular CSS classes */
|
||
|
|
* .red { background:red; }
|
||
|
|
* .large-text { font-size:20px; }
|
||
|
|
*
|
||
|
|
* /* we can also use a keyframe animation and $animateCss will make it work alongside the transition */
|
||
|
|
* .pulse-twice {
|
||
|
|
* animation: 0.5s pulse linear 2;
|
||
|
|
* -webkit-animation: 0.5s pulse linear 2;
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* @keyframes pulse {
|
||
|
|
* from { transform: scale(0.5); }
|
||
|
|
* to { transform: scale(1.5); }
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* @-webkit-keyframes pulse {
|
||
|
|
* from { -webkit-transform: scale(0.5); }
|
||
|
|
* to { -webkit-transform: scale(1.5); }
|
||
|
|
* }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen.
|
||
|
|
*
|
||
|
|
* ## How the Options are handled
|
||
|
|
*
|
||
|
|
* `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation
|
||
|
|
* works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline
|
||
|
|
* styles using the `from` and `to` properties.
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* var animator = $animateCss(element, {
|
||
|
|
* from: { background:'red' },
|
||
|
|
* to: { background:'blue' }
|
||
|
|
* });
|
||
|
|
* animator.start();
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* .rotating-animation {
|
||
|
|
* animation:0.5s rotate linear;
|
||
|
|
* -webkit-animation:0.5s rotate linear;
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* @keyframes rotate {
|
||
|
|
* from { transform: rotate(0deg); }
|
||
|
|
* to { transform: rotate(360deg); }
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* @-webkit-keyframes rotate {
|
||
|
|
* from { -webkit-transform: rotate(0deg); }
|
||
|
|
* to { -webkit-transform: rotate(360deg); }
|
||
|
|
* }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is
|
||
|
|
* going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition
|
||
|
|
* style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition
|
||
|
|
* and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied
|
||
|
|
* and spread across the transition and keyframe animation.
|
||
|
|
*
|
||
|
|
* ## What is returned
|
||
|
|
*
|
||
|
|
* `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually
|
||
|
|
* start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are
|
||
|
|
* added and removed on the element). Once `$animateCss` is called it will return an object with the following properties:
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* var animator = $animateCss(element, { ... });
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Now what do the contents of our `animator` variable look like:
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* {
|
||
|
|
* // starts the animation
|
||
|
|
* start: Function,
|
||
|
|
*
|
||
|
|
* // ends (aborts) the animation
|
||
|
|
* end: Function
|
||
|
|
* }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends.
|
||
|
|
* If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and stlyes may have been
|
||
|
|
* applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties
|
||
|
|
* and that changing them will not reconfigure the parameters of the animation.
|
||
|
|
*
|
||
|
|
* ### runner.done() vs runner.then()
|
||
|
|
* It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the
|
||
|
|
* runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**.
|
||
|
|
* Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()`
|
||
|
|
* unless you really need a digest to kick off afterwards.
|
||
|
|
*
|
||
|
|
* Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss
|
||
|
|
* (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code).
|
||
|
|
* Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works.
|
||
|
|
*
|
||
|
|
* @param {DOMElement} element the element that will be animated
|
||
|
|
* @param {object} options the animation-related options that will be applied during the animation
|
||
|
|
*
|
||
|
|
* * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied
|
||
|
|
* to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.)
|
||
|
|
* * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both).
|
||
|
|
* * `transition` - The raw CSS transition style that will be used (e.g. `1s linear all`).
|
||
|
|
* * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`).
|
||
|
|
* * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation.
|
||
|
|
* * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition.
|
||
|
|
* * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation.
|
||
|
|
* * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation.
|
||
|
|
* * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0`
|
||
|
|
* is provided then the animation will be skipped entirely.
|
||
|
|
* * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is
|
||
|
|
* used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value
|
||
|
|
* of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same
|
||
|
|
* CSS delay value.
|
||
|
|
* * `stagger` - A numeric time value representing the delay between successively animated elements
|
||
|
|
* ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.})
|
||
|
|
* * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a
|
||
|
|
* * `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`)
|
||
|
|
* * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occuring on the classes being added and removed.)
|
||
|
|
*
|
||
|
|
* @return {object} an object with start and end methods and details about the animation.
|
||
|
|
*
|
||
|
|
* * `start` - The method to start the animation. This will return a `Promise` when called.
|
||
|
|
* * `end` - This method will cancel the animation and remove all applied CSS classes and styles.

* @ngdoc module
|
||
|
|
* @name ngAnimate
|
||
|
|
* @description
|
||
|
|
*
|
||
|
|
* The `ngAnimate` module provides support for CSS-based animations (keyframes and transitions) as well as JavaScript-based animations via
|
||
|
|
* callback hooks. Animations are not enabled by default, however, by including `ngAnimate` then the animation hooks are enabled for an Angular app.
|
||
|
|
*
|
||
|
|
* <div doc-module-components="ngAnimate"></div>
|
||
|
|
*
|
||
|
|
* # Usage
|
||
|
|
* Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based
|
||
|
|
* using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For
|
||
|
|
* both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within
|
||
|
|
* the HTML element that the animation will be triggered on.
|
||
|
|
*
|
||
|
|
* ## Directive Support
|
||
|
|
* The following directives are "animation aware":
|
||
|
|
*
|
||
|
|
* | Directive | Supported Animations |
|
||
|
|
* |----------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------|
|
||
|
|
* | {@link ng.directive:ngRepeat#animations ngRepeat} | enter, leave and move |
|
||
|
|
* | {@link ngRoute.directive:ngView#animations ngView} | enter and leave |
|
||
|
|
* | {@link ng.directive:ngInclude#animations ngInclude} | enter and leave |
|
||
|
|
* | {@link ng.directive:ngSwitch#animations ngSwitch} | enter and leave |
|
||
|
|
* | {@link ng.directive:ngIf#animations ngIf} | enter and leave |
|
||
|
|
* | {@link ng.directive:ngClass#animations ngClass} | add and remove (the CSS class(es) present) |
|
||
|
|
* | {@link ng.directive:ngShow#animations ngShow} & {@link ng.directive:ngHide#animations ngHide} | add and remove (the ng-hide class value) |
|
||
|
|
* | {@link ng.directive:form#animation-hooks form} & {@link ng.directive:ngModel#animation-hooks ngModel} | add and remove (dirty, pristine, valid, invalid & all other validations) |
|
||
|
|
* | {@link module:ngMessages#animations ngMessages} | add and remove (ng-active & ng-inactive) |
|
||
|
|
* | {@link module:ngMessages#animations ngMessage} | enter and leave |
|
||
|
|
*
|
||
|
|
* (More information can be found by visiting each the documentation associated with each directive.)
|
||
|
|
*
|
||
|
|
* ## CSS-based Animations
|
||
|
|
*
|
||
|
|
* CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML
|
||
|
|
* and CSS code we can create an animation that will be picked up by Angular when an the underlying directive performs an operation.
|
||
|
|
*
|
||
|
|
* The example below shows how an `enter` animation can be made possible on a element using `ng-if`:
|
||
|
|
*
|
||
|
|
* ```html
|
||
|
|
* <div ng-if="bool" class="fade">
|
||
|
|
* Fade me in out
|
||
|
|
* </div>
|
||
|
|
* <button ng-click="bool=true">Fade In!</button>
|
||
|
|
* <button ng-click="bool=false">Fade Out!</button>
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Notice the CSS class **fade**? We can now create the CSS transition code that references this class:
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* /* The starting CSS styles for the enter animation */
|
||
|
|
* .fade.ng-enter {
|
||
|
|
* transition:0.5s linear all;
|
||
|
|
* opacity:0;
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* /* The finishing CSS styles for the enter animation */
|
||
|
|
* .fade.ng-enter.ng-enter-active {
|
||
|
|
* opacity:1;
|
||
|
|
* }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two
|
||
|
|
* generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition
|
||
|
|
* code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards.
|
||
|
|
*
|
||
|
|
* If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions:
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* /* now the element will fade out before it is removed from the DOM */
|
||
|
|
* .fade.ng-leave {
|
||
|
|
* transition:0.5s linear all;
|
||
|
|
* opacity:1;
|
||
|
|
* }
|
||
|
|
* .fade.ng-leave.ng-leave-active {
|
||
|
|
* opacity:0;
|
||
|
|
* }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class:
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* /* there is no need to define anything inside of the destination
|
||
|
|
* CSS class since the keyframe will take charge of the animation */
|
||
|
|
* .fade.ng-leave {
|
||
|
|
* animation: my_fade_animation 0.5s linear;
|
||
|
|
* -webkit-animation: my_fade_animation 0.5s linear;
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* @keyframes my_fade_animation {
|
||
|
|
* from { opacity:1; }
|
||
|
|
* to { opacity:0; }
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* @-webkit-keyframes my_fade_animation {
|
||
|
|
* from { opacity:1; }
|
||
|
|
* to { opacity:0; }
|
||
|
|
* }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element.
|
||
|
|
*
|
||
|
|
* ### CSS Class-based Animations
|
||
|
|
*
|
||
|
|
* Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different
|
||
|
|
* naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added
|
||
|
|
* and removed.
|
||
|
|
*
|
||
|
|
* For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class:
|
||
|
|
*
|
||
|
|
* ```html
|
||
|
|
* <div ng-show="bool" class="fade">
|
||
|
|
* Show and hide me
|
||
|
|
* </div>
|
||
|
|
* <button ng-click="bool=true">Toggle</button>
|
||
|
|
*
|
||
|
|
* <style>
|
||
|
|
* .fade.ng-hide {
|
||
|
|
* transition:0.5s linear all;
|
||
|
|
* opacity:0;
|
||
|
|
* }
|
||
|
|
* </style>
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since
|
||
|
|
* ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest.
|
||
|
|
*
|
||
|
|
* In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation
|
||
|
|
* with CSS styles.
|
||
|
|
*
|
||
|
|
* ```html
|
||
|
|
* <div ng-class="{on:onOff}" class="highlight">
|
||
|
|
* Highlight this box
|
||
|
|
* </div>
|
||
|
|
* <button ng-click="onOff=!onOff">Toggle</button>
|
||
|
|
*
|
||
|
|
* <style>
|
||
|
|
* .highlight {
|
||
|
|
* transition:0.5s linear all;
|
||
|
|
* }
|
||
|
|
* .highlight.on-add {
|
||
|
|
* background:white;
|
||
|
|
* }
|
||
|
|
* .highlight.on {
|
||
|
|
* background:yellow;
|
||
|
|
* }
|
||
|
|
* .highlight.on-remove {
|
||
|
|
* background:black;
|
||
|
|
* }
|
||
|
|
* </style>
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* We can also make use of CSS keyframes by placing them within the CSS classes.
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* ### CSS Staggering Animations
|
||
|
|
* 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 (versions >=1.2) 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).
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* .my-animation.ng-enter {
|
||
|
|
* /* standard transition code */
|
||
|
|
* transition: 1s linear all;
|
||
|
|
* opacity:0;
|
||
|
|
* }
|
||
|
|
* .my-animation.ng-enter-stagger {
|
||
|
|
* /* this will have a 100ms delay between each successive leave animation */
|
||
|
|
* transition-delay: 0.1s;
|
||
|
|
*
|
||
|
|
* /* in case the stagger doesn't work then the duration value
|
||
|
|
* must be set to 0 to avoid an accidental CSS inheritance */
|
||
|
|
* transition-duration: 0s;
|
||
|
|
* }
|
||
|
|
* .my-animation.ng-enter.ng-enter-active {
|
||
|
|
* /* standard transition styles */
|
||
|
|
* opacity:1;
|
||
|
|
* }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* 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 $animate. However, the restrictions surrounding this
|
||
|
|
* are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
|
||
|
|
* will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired.
|
||
|
|
*
|
||
|
|
* The following code will issue the **ng-leave-stagger** event on the element provided:
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* 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
|
||
|
|
*
|
||
|
|
* window.requestAnimationFrame(function() {
|
||
|
|
* //stagger has reset itself
|
||
|
|
* $animate.leave(kids[5]); //stagger index=0
|
||
|
|
* $animate.leave(kids[6]); //stagger index=1
|
||
|
|
*
|
||
|
|
* $scope.$digest();
|
||
|
|
* });
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Stagger animations are currently only supported within CSS-defined animations.
|
||
|
|
*
|
||
|
|
* ### The `ng-animate` CSS class
|
||
|
|
*
|
||
|
|
* When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation.
|
||
|
|
* This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations).
|
||
|
|
*
|
||
|
|
* Therefore, animations can be applied to an element using this temporary class directly via CSS.
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* .zipper.ng-animate {
|
||
|
|
* transition:0.5s linear all;
|
||
|
|
* }
|
||
|
|
* .zipper.ng-enter {
|
||
|
|
* opacity:0;
|
||
|
|
* }
|
||
|
|
* .zipper.ng-enter.ng-enter-active {
|
||
|
|
* opacity:1;
|
||
|
|
* }
|
||
|
|
* .zipper.ng-leave {
|
||
|
|
* opacity:1;
|
||
|
|
* }
|
||
|
|
* .zipper.ng-leave.ng-leave-active {
|
||
|
|
* opacity:0;
|
||
|
|
* }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove
|
||
|
|
* the CSS class once an animation has completed.)
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* ## JavaScript-based Animations
|
||
|
|
*
|
||
|
|
* ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared
|
||
|
|
* CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the
|
||
|
|
* `module.animation()` module function we can register the ainmation.
|
||
|
|
*
|
||
|
|
* Let's see an example of a enter/leave animation using `ngRepeat`:
|
||
|
|
*
|
||
|
|
* ```html
|
||
|
|
* <div ng-repeat="item in items" class="slide">
|
||
|
|
* {{ item }}
|
||
|
|
* </div>
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`:
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* myModule.animation('.slide', [function() {
|
||
|
|
* return {
|
||
|
|
* // make note that other events (like addClass/removeClass)
|
||
|
|
* // have different function input parameters
|
||
|
|
* enter: function(element, doneFn) {
|
||
|
|
* jQuery(element).fadeIn(1000, doneFn);
|
||
|
|
*
|
||
|
|
* // remember to call doneFn so that angular
|
||
|
|
* // knows that the animation has concluded
|
||
|
|
* },
|
||
|
|
*
|
||
|
|
* move: function(element, doneFn) {
|
||
|
|
* jQuery(element).fadeIn(1000, doneFn);
|
||
|
|
* },
|
||
|
|
*
|
||
|
|
* leave: function(element, doneFn) {
|
||
|
|
* jQuery(element).fadeOut(1000, doneFn);
|
||
|
|
* }
|
||
|
|
* }
|
||
|
|
* }]
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as
|
||
|
|
* greensock.js and velocity.js.
|
||
|
|
*
|
||
|
|
* If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define
|
||
|
|
* our animations inside of the same registered animation, however, the function input arguments are a bit different:
|
||
|
|
*
|
||
|
|
* ```html
|
||
|
|
* <div ng-class="color" class="colorful">
|
||
|
|
* this box is moody
|
||
|
|
* </div>
|
||
|
|
* <button ng-click="color='red'">Change to red</button>
|
||
|
|
* <button ng-click="color='blue'">Change to blue</button>
|
||
|
|
* <button ng-click="color='green'">Change to green</button>
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* myModule.animation('.colorful', [function() {
|
||
|
|
* return {
|
||
|
|
* addClass: function(element, className, doneFn) {
|
||
|
|
* // do some cool animation and call the doneFn
|
||
|
|
* },
|
||
|
|
* removeClass: function(element, className, doneFn) {
|
||
|
|
* // do some cool animation and call the doneFn
|
||
|
|
* },
|
||
|
|
* setClass: function(element, addedClass, removedClass, doneFn) {
|
||
|
|
* // do some cool animation and call the doneFn
|
||
|
|
* }
|
||
|
|
* }
|
||
|
|
* }]
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* ## CSS + JS Animations Together
|
||
|
|
*
|
||
|
|
* AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of Angular,
|
||
|
|
* defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking
|
||
|
|
* charge of the animation**:
|
||
|
|
*
|
||
|
|
* ```html
|
||
|
|
* <div ng-if="bool" class="slide">
|
||
|
|
* Slide in and out
|
||
|
|
* </div>
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* myModule.animation('.slide', [function() {
|
||
|
|
* return {
|
||
|
|
* enter: function(element, doneFn) {
|
||
|
|
* jQuery(element).slideIn(1000, doneFn);
|
||
|
|
* }
|
||
|
|
* }
|
||
|
|
* }]
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* .slide.ng-enter {
|
||
|
|
* transition:0.5s linear all;
|
||
|
|
* transform:translateY(-100px);
|
||
|
|
* }
|
||
|
|
* .slide.ng-enter.ng-enter-active {
|
||
|
|
* transform:translateY(0);
|
||
|
|
* }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the
|
||
|
|
* lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from
|
||
|
|
* our own JS-based animation code:
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* myModule.animation('.slide', ['$animateCss', function($animateCss) {
|
||
|
|
* return {
|
||
|
|
* enter: function(element, doneFn) {
|
||
|
|
* // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`.
|
||
|
|
* var runner = $animateCss(element, {
|
||
|
|
* event: 'enter',
|
||
|
|
* structural: true
|
||
|
|
* }).start();
|
||
|
|
* runner.done(doneFn);
|
||
|
|
* }
|
||
|
|
* }
|
||
|
|
* }]
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework.
|
||
|
|
*
|
||
|
|
* The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or
|
||
|
|
* keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that
|
||
|
|
* data into `$animateCss` directly:
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* myModule.animation('.slide', ['$animateCss', function($animateCss) {
|
||
|
|
* return {
|
||
|
|
* enter: function(element, doneFn) {
|
||
|
|
* var runner = $animateCss(element, {
|
||
|
|
* event: 'enter',
|
||
|
|
* structural: true,
|
||
|
|
* addClass: 'maroon-setting',
|
||
|
|
* from: { height:0 },
|
||
|
|
* to: { height: 200 }
|
||
|
|
* }).start();
|
||
|
|
*
|
||
|
|
* runner.done(doneFn);
|
||
|
|
* }
|
||
|
|
* }
|
||
|
|
* }]
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Now we can fill in the rest via our transition CSS code:
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* /* the transition tells ngAnimate to make the animation happen */
|
||
|
|
* .slide.ng-enter { transition:0.5s linear all; }
|
||
|
|
*
|
||
|
|
* /* this extra CSS class will be absorbed into the transition
|
||
|
|
* since the $animateCss code is adding the class */
|
||
|
|
* .maroon-setting { background:red; }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over.
|
||
|
|
*
|
||
|
|
* To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}.

||
|
|
*
|
||
|
|
* ## Animation Anchoring (via `ng-animate-ref`)
|
||
|
|
*
|
||
|
|
* ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between
|
||
|
|
* structural areas of an application (like views) by pairing up elements using an attribute
|
||
|
|
* called `ng-animate-ref`.
|
||
|
|
*
|
||
|
|
* Let's say for example we have two views that are managed by `ng-view` and we want to show
|
||
|
|
* that there is a relationship between two components situated in within these views. By using the
|
||
|
|
* `ng-animate-ref` attribute we can identify that the two components are paired together and we
|
||
|
|
* can then attach an animation, which is triggered when the view changes.
|
||
|
|
*
|
||
|
|
* Say for example we have the following template code:
|
||
|
|
*
|
||
|
|
* ```html
|
||
|
|
* <!-- index.html -->
|
||
|
|
* <div ng-view class="view-animation">
|
||
|
|
* </div>
|
||
|
|
*
|
||
|
|
* <!-- home.html -->
|
||
|
|
* <a href="#/banner-page">
|
||
|
|
* <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
|
||
|
|
* </a>
|
||
|
|
*
|
||
|
|
* <!-- banner-page.html -->
|
||
|
|
* <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Now, when the view changes (once the link is clicked), ngAnimate will examine the
|
||
|
|
* HTML contents to see if there is a match reference between any components in the view
|
||
|
|
* that is leaving and the view that is entering. It will scan both the view which is being
|
||
|
|
* removed (leave) and inserted (enter) to see if there are any paired DOM elements that
|
||
|
|
* contain a matching ref value.
|
||
|
|
*
|
||
|
|
* The two images match since they share the same ref value. ngAnimate will now create a
|
||
|
|
* transport element (which is a clone of the first image element) and it will then attempt
|
||
|
|
* to animate to the position of the second image element in the next view. For the animation to
|
||
|
|
* work a special CSS class called `ng-anchor` will be added to the transported element.
|
||
|
|
*
|
||
|
|
* We can now attach a transition onto the `.banner.ng-anchor` CSS class and then
|
||
|
|
* ngAnimate will handle the entire transition for us as well as the addition and removal of
|
||
|
|
* any changes of CSS classes between the elements:
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* .banner.ng-anchor {
|
||
|
|
* /* this animation will last for 1 second since there are
|
||
|
|
* two phases to the animation (an `in` and an `out` phase) */
|
||
|
|
* transition:0.5s linear all;
|
||
|
|
* }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* We also **must** include animations for the views that are being entered and removed
|
||
|
|
* (otherwise anchoring wouldn't be possible since the new view would be inserted right away).
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* .view-animation.ng-enter, .view-animation.ng-leave {
|
||
|
|
* transition:0.5s linear all;
|
||
|
|
* position:fixed;
|
||
|
|
* left:0;
|
||
|
|
* top:0;
|
||
|
|
* width:100%;
|
||
|
|
* }
|
||
|
|
* .view-animation.ng-enter {
|
||
|
|
* transform:translateX(100%);
|
||
|
|
* }
|
||
|
|
* .view-animation.ng-leave,
|
||
|
|
* .view-animation.ng-enter.ng-enter-active {
|
||
|
|
* transform:translateX(0%);
|
||
|
|
* }
|
||
|
|
* .view-animation.ng-leave.ng-leave-active {
|
||
|
|
* transform:translateX(-100%);
|
||
|
|
* }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur:
|
||
|
|
* an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away
|
||
|
|
* from its origin. Once that animation is over then the `in` stage occurs which animates the
|
||
|
|
* element to its destination. The reason why there are two animations is to give enough time
|
||
|
|
* for the enter animation on the new element to be ready.
|
||
|
|
*
|
||
|
|
* The example above sets up a transition for both the in and out phases, but we can also target the out or
|
||
|
|
* in phases directly via `ng-anchor-out` and `ng-anchor-in`.
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* .banner.ng-anchor-out {
|
||
|
|
* transition: 0.5s linear all;
|
||
|
|
*
|
||
|
|
* /* the scale will be applied during the out animation,
|
||
|
|
* but will be animated away when the in animation runs */
|
||
|
|
* transform: scale(1.2);
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* .banner.ng-anchor-in {
|
||
|
|
* transition: 1s linear all;
|
||
|
|
* }
|
||
|
|
* ```

|
|
* ### How is the element transported?
|
||
|
|
*
|
||
|
|
* When an anchor animation occurs, ngAnimate will clone the starting element and position it exactly where the starting
|
||
|
|
* element is located on screen via absolute positioning. The cloned element will be placed inside of the root element
|
||
|
|
* of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The
|
||
|
|
* element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match
|
||
|
|
* the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied
|
||
|
|
* to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class
|
||
|
|
* is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element
|
||
|
|
* will become visible since the shim class will be removed.
|
||
|
|
*
|
||
|
|
* ### How is the morphing handled?
|
||
|
|
*
|
||
|
|
* CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out
|
||
|
|
* what CSS classes differ between the starting element and the destination element. These different CSS classes
|
||
|
|
* will be added/removed on the anchor element and a transition will be applied (the transition that is provided
|
||
|
|
* in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will
|
||
|
|
* make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that
|
||
|
|
* do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since
|
||
|
|
* the cloned element is placed inside of root element which is likely close to the body element).
|
||
|
|
*
|
||
|
|
* Note that if the root element is on the `<html>` element then the cloned node will be placed inside of body.
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* ## Using $animate in your directive code
|
||
|
|
*
|
||
|
|
* So far we've explored how to feed in animations into an Angular application, but how do we trigger animations within our own directives in our application?
|
||
|
|
* By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's
|
||
|
|
* imagine we have a greeting box that shows and hides itself when the data changes
|
||
|
|
*
|
||
|
|
* ```html
|
||
|
|
* <greeting-box active="onOrOff">Hi there</greeting-box>
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* ngModule.directive('greetingBox', ['$animate', function($animate) {
|
||
|
|
* return function(scope, element, attrs) {
|
||
|
|
* attrs.$observe('active', function(value) {
|
||
|
|
* value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on');
|
||
|
|
* });
|
||
|
|
* });
|
||
|
|
* }]);
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element
|
||
|
|
* in our HTML code then we can trigger a CSS or JS animation to happen.
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* /* normally we would create a CSS class to reference on the element */
|
||
|
|
* greeting-box.on { transition:0.5s linear all; background:green; color:white; }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's
|
||
|
|
* possible be sure to visit the {@link ng.$animate $animate service API page}.
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* ### Preventing Collisions With Third Party Libraries
|
||
|
|
*
|
||
|
|
* Some third-party frameworks place animation duration defaults across many element or className
|
||
|
|
* selectors in order to make their code small and reuseable. This can lead to issues with ngAnimate, which
|
||
|
|
* is expecting actual animations on these elements and has to wait for their completion.
|
||
|
|
*
|
||
|
|
* You can prevent this unwanted behavior by using a prefix on all your animation classes:
|
||
|
|
*
|
||
|
|
* ```css
|
||
|
|
* /* prefixed with animate- */
|
||
|
|
* .animate-fade-add.animate-fade-add-active {
|
||
|
|
* transition:1s linear all;
|
||
|
|
* opacity:0;
|
||
|
|
* }
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* You then configure `$animate` to enforce this prefix:
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* $animateProvider.classNameFilter(/animate-/);
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* This also may provide your application with a speed boost since only specific elements containing CSS class prefix
|
||
|
|
* will be evaluated for animation when any DOM changes occur in the application.
|
||
|
|
*
|
||
|
|
* ## Callbacks and Promises
|
||
|
|
*
|
||
|
|
* When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger
|
||
|
|
* an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has
|
||
|
|
* ended by chaining onto the returned promise that animation method returns.
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* // somewhere within the depths of the directive
|
||
|
|
* $animate.enter(element, parent).then(function() {
|
||
|
|
* //the animation has completed
|
||
|
|
* });
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* (Note that earlier versions of Angular prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case
|
||
|
|
* anymore.)
|
||
|
|
*
|
||
|
|
* In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering
|
||
|
|
* an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view
|
||
|
|
* routing controller to hook into that:
|
||
|
|
*
|
||
|
|
* ```js
|
||
|
|
* ngModule.controller('HomePageController', ['$animate', function($animate) {
|
||
|
|
* $animate.on('enter', ngViewElement, function(element) {
|
||
|
|
* // the animation for this route has completed
|
||
|
|
* }]);
|
||
|
|
* }])
|
||
|
|
* ```
|
||
|
|
*
|
||
|
|
* (Note that you will need to trigger a digest within the callback to get angular to notice any scope-related changes.)
