|
---|
| 523 | *
|
---|
| 524 | * @description
|
---|
| 525 | * The `$animateCss` service is a useful utility to trigger customized CSS-based transitions/keyframes
|
---|
| 526 | * from a JavaScript-based animation or directly from a directive. The purpose of `$animateCss` is NOT
|
---|
| 527 | * to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or
|
---|
| 528 | * directives to create more complex animations that can be purely driven using CSS code.
|
---|
| 529 | *
|
---|
| 530 | * Note that only browsers that support CSS transitions and/or keyframe animations are capable of
|
---|
| 531 | * rendering animations triggered via `$animateCss` (bad news for IE9 and lower).
|
---|
| 532 | *
|
---|
| 533 | * ## General Use
|
---|
| 534 | * Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that
|
---|
| 535 | * is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however,
|
---|
| 536 | * any automatic control over cancelling animations and/or preventing animations from being run on
|
---|
| 537 | * child elements will not be handled by AngularJS. For this to work as expected, please use `$animate` to
|
---|
| 538 | * trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger
|
---|
| 539 | * the CSS animation.
|
---|
| 540 | *
|
---|
| 541 | * The example below shows how we can create a folding animation on an element using `ng-if`:
|
---|
| 542 | *
|
---|
| 543 | * ```html
|
---|
| 544 | * <!-- notice the `fold-animation` CSS class -->
|
---|
| 545 | * <div ng-if="onOff" class="fold-animation">
|
---|
| 546 | * This element will go BOOM
|
---|
| 547 | * </div>
|
---|
| 548 | * <button ng-click="onOff=true">Fold In</button>
|
---|
| 549 | * ```
|
---|
| 550 | *
|
---|
| 551 | * Now we create the **JavaScript animation** that will trigger the CSS transition:
|
---|
| 552 | *
|
---|
| 553 | * ```js
|
---|
| 554 | * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
|
---|
| 555 | * return {
|
---|
| 556 | * enter: function(element, doneFn) {
|
---|
| 557 | * var height = element[0].offsetHeight;
|
---|
| 558 | * return $animateCss(element, {
|
---|
| 559 | * from: { height:'0px' },
|
---|
| 560 | * to: { height:height + 'px' },
|
---|
| 561 | * duration: 1 // one second
|
---|
| 562 | * });
|
---|
| 563 | * }
|
---|
| 564 | * }
|
---|
| 565 | * }]);
|
---|
| 566 | * ```
|
---|
| 567 | *
|
---|
| 568 | * ## More Advanced Uses
|
---|
| 569 | *
|
---|
| 570 | * `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks
|
---|
| 571 | * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code.
|
---|
| 572 | *
|
---|
| 573 | * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation,
|
---|
| 574 | * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with
|
---|
| 575 | * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order
|
---|
| 576 | * to provide a working animation that will run in CSS.
|
---|
| 577 | *
|
---|
| 578 | * The example below showcases a more advanced version of the `.fold-animation` from the example above:
|
---|
| 579 | *
|
---|
| 580 | * ```js
|
---|
| 581 | * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
|
---|
| 582 | * return {
|
---|
| 583 | * enter: function(element, doneFn) {
|
---|
| 584 | * var height = element[0].offsetHeight;
|
---|
| 585 | * return $animateCss(element, {
|
---|
| 586 | * addClass: 'red large-text pulse-twice',
|
---|
| 587 | * easing: 'ease-out',
|
---|
| 588 | * from: { height:'0px' },
|
---|
| 589 | * to: { height:height + 'px' },
|
---|
| 590 | * duration: 1 // one second
|
---|
| 591 | * });
|
---|
| 592 | * }
|
---|
| 593 | * }
|
---|
| 594 | * }]);
|
---|
| 595 | * ```
|
---|
| 596 | *
|
---|
| 597 | * Since we're adding/removing CSS classes then the CSS transition will also pick those up:
|
---|
| 598 | *
|
---|
| 599 | * ```css
|
---|
| 600 | * /* since a hardcoded duration value of 1 was provided in the JavaScript animation code,
|
---|
| 601 | * the CSS classes below will be transitioned despite them being defined as regular CSS classes */
|
---|
| 602 | * .red { background:red; }
|
---|
| 603 | * .large-text { font-size:20px; }
|
---|
| 604 | *
|
---|
| 605 | * /* we can also use a keyframe animation and $animateCss will make it work alongside the transition */
|
---|
| 606 | * .pulse-twice {
|
---|
| 607 | * animation: 0.5s pulse linear 2;
|
---|
| 608 | * -webkit-animation: 0.5s pulse linear 2;
|
---|
| 609 | * }
|
---|
| 610 | *
|
---|
| 611 | * @keyframes pulse {
|
---|
| 612 | * from { transform: scale(0.5); }
|
---|
| 613 | * to { transform: scale(1.5); }
|
---|
| 614 | * }
|
---|
| 615 | *
|
---|
| 616 | * @-webkit-keyframes pulse {
|
---|
| 617 | * from { -webkit-transform: scale(0.5); }
|
---|
| 618 | * to { -webkit-transform: scale(1.5); }
|
---|
| 619 | * }
|
---|
| 620 | * ```
|
---|
| 621 | *
|
---|
| 622 | * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen.
|
---|
| 623 | *
|
---|
| 624 | * ## How the Options are handled
|
---|
| 625 | *
|
---|
| 626 | * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation
|
---|
| 627 | * 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
|
---|
| 628 | * styles using the `from` and `to` properties.
|
---|
| 629 | *
|
---|
| 630 | * ```js
|
---|
| 631 | * var animator = $animateCss(element, {
|
---|
| 632 | * from: { background:'red' },
|
---|
| 633 | * to: { background:'blue' }
|
---|
| 634 | * });
|
---|
| 635 | * animator.start();
|
---|
| 636 | * ```
|
---|
| 637 | *
|
---|
| 638 | * ```css
|
---|
| 639 | * .rotating-animation {
|
---|
| 640 | * animation:0.5s rotate linear;
|
---|
| 641 | * -webkit-animation:0.5s rotate linear;
|
---|
| 642 | * }
|
---|
| 643 | *
|
---|
| 644 | * @keyframes rotate {
|
---|
| 645 | * from { transform: rotate(0deg); }
|
---|
| 646 | * to { transform: rotate(360deg); }
|
---|
| 647 | * }
|
---|
| 648 | *
|
---|
| 649 | * @-webkit-keyframes rotate {
|
---|
| 650 | * from { -webkit-transform: rotate(0deg); }
|
---|
| 651 | * to { -webkit-transform: rotate(360deg); }
|
---|
| 652 | * }
|
---|
| 653 | * ```
|
---|
| 654 | *
|
---|
| 655 | * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is
|
---|
| 656 | * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition
|
---|
| 657 | * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition
|
---|
| 658 | * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied
|
---|
| 659 | * and spread across the transition and keyframe animation.
|
---|
| 660 | *
|
---|
| 661 | * ## What is returned
|
---|
| 662 | *
|
---|
| 663 | * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually
|
---|
| 664 | * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are
|
---|
| 665 | * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties:
|
---|
| 666 | *
|
---|
| 667 | * ```js
|
---|
| 668 | * var animator = $animateCss(element, { ... });
|
---|
| 669 | * ```
|
---|
| 670 | *
|
---|
| 671 | * Now what do the contents of our `animator` variable look like:
|
---|
| 672 | *
|
---|
| 673 | * ```js
|
---|
| 674 | * {
|
---|
| 675 | * // starts the animation
|
---|
| 676 | * start: Function,
|
---|
| 677 | *
|
---|
| 678 | * // ends (aborts) the animation
|
---|
| 679 | * end: Function
|
---|
| 680 | * }
|
---|
| 681 | * ```
|
---|
| 682 | *
|
---|
| 683 | * 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.
|
---|
| 684 | * 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 styles may have been
|
---|
| 685 | * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties
|
---|
| 686 | * and that changing them will not reconfigure the parameters of the animation.
|
---|
| 687 | *
|
---|
| 688 | * ### runner.done() vs runner.then()
|
---|
| 689 | * 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
|
---|
| 690 | * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**.
|
---|
| 691 | * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()`
|
---|
| 692 | * unless you really need a digest to kick off afterwards.
|
---|
| 693 | *
|
---|
| 694 | * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss
|
---|
| 695 | * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code).
|
---|
| 696 | * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works.
|
---|
| 697 | *
|
---|
| 698 | * @param {DOMElement} element the element that will be animated
|
---|
| 699 | * @param {object} options the animation-related options that will be applied during the animation
|
---|
| 700 | *
|
---|
| 701 | * * `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
|
---|
| 702 | * 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.)
|
---|
| 703 | * * `structural` - Indicates that the `ng-` prefix will be added to the event class. Setting to `false` or omitting will turn `ng-EVENT` and
|
---|
| 704 | * `ng-EVENT-active` in `EVENT` and `EVENT-active`. Unused if `event` is omitted.
|
---|
| 705 | * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both).
|
---|
| 706 | * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`).
|
---|
| 707 | * * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`).
|
---|
| 708 | * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation.
|
---|
| 709 | * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition.
|
---|
| 710 | * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation.
|
---|
| 711 | * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation.
|
---|
| 712 | * * `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`
|
---|
| 713 | * is provided then the animation will be skipped entirely.
|
---|
| 714 | * * `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
|
---|
| 715 | * 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
|
---|
| 716 | * 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
|
---|
| 717 | * CSS delay value.
|
---|
| 718 | * * `stagger` - A numeric time value representing the delay between successively animated elements
|
---|
| 719 | * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.})
|
---|
| 720 | * * `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
|
---|
| 721 | * `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`)
|
---|
| 722 | * * `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 occurring on the classes being added and removed.)
|
---|
| 723 | * * `cleanupStyles` - Whether or not the provided `from` and `to` styles will be removed once
|
---|
| 724 | * the animation is closed. This is useful for when the styles are used purely for the sake of
|
---|
| 725 | * the animation and do not have a lasting visual effect on the element (e.g. a collapse and open animation).
|
---|
| 726 | * By default this value is set to `false`.
|
---|
| 727 | *
|
---|
| 728 | * @return {object} an object with start and end methods and details about the animation.
|
---|
| 729 | *
|
---|
| 730 | * * `start` - The method to start the animation. This will return a `Promise` when called.
|
---|
| 731 | * * `end` - This method will cancel the animation and remove all applied CSS classes and styles.

|
---|
| 3479 | * @description
|
---|
| 3480 | *
|
---|
| 3481 | * The `ngAnimate` module provides support for CSS-based animations (keyframes and transitions) as well as JavaScript-based animations via
|
---|
| 3482 | * callback hooks. Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an AngularJS app.
|
---|
| 3483 | *
|
---|
| 3484 | * ## Usage
|
---|
| 3485 | * 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
|
---|
| 3486 | * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For
|
---|
| 3487 | * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within
|
---|
| 3488 | * the HTML element that the animation will be triggered on.
|
---|
| 3489 | *
|
---|
| 3490 | * ## Directive Support
|
---|
| 3491 | * The following directives are "animation aware":
|
---|
| 3492 | *
|
---|
| 3493 | * | Directive | Supported Animations |
|
---|
| 3494 | * |-------------------------------------------------------------------------------|---------------------------------------------------------------------------|
|
---|
| 3495 | * | {@link ng.directive:form#animations form / ngForm} | add and remove ({@link ng.directive:form#css-classes various classes}) |
|
---|
| 3496 | * | {@link ngAnimate.directive:ngAnimateSwap#animations ngAnimateSwap} | enter and leave |
|
---|
| 3497 | * | {@link ng.directive:ngClass#animations ngClass / {{class}​}} | add and remove |

|
---|
| 3500 | * | {@link ng.directive:ngHide#animations ngHide} | add and remove (the `ng-hide` class) |
|
---|

|
---|
| 3502 | * | {@link ng.directive:ngInclude#animations ngInclude} | enter and leave |
|
---|
| 3503 | * | {@link module:ngMessages#animations ngMessage / ngMessageExp} | enter and leave |
|
---|
| 3504 | * | {@link module:ngMessages#animations ngMessages} | add and remove (the `ng-active`/`ng-inactive` classes) |
|
---|
| 3505 | * | {@link ng.directive:ngModel#animations ngModel} | add and remove ({@link ng.directive:ngModel#css-classes various classes}) |
|
---|
| 3506 | * | {@link ng.directive:ngRepeat#animations ngRepeat} | enter, leave, and move |
|
---|
| 3507 | * | {@link ng.directive:ngShow#animations ngShow} | add and remove (the `ng-hide` class) |
|
---|
| 3508 | * | {@link ng.directive:ngSwitch#animations ngSwitch} | enter and leave |
|
---|
| 3509 | * | {@link ngRoute.directive:ngView#animations ngView} | enter and leave |
|
---|
| 3510 | *
|
---|
| 3511 | * (More information can be found by visiting the documentation associated with each directive.)
|
---|
| 3512 | *
|
---|
| 3513 | * For a full breakdown of the steps involved during each animation event, refer to the
|
---|
| 3514 | * {@link ng.$animate `$animate` API docs}.
|
---|
| 3515 | *
|
---|
| 3516 | * ## CSS-based Animations
|
---|
| 3517 | *
|
---|
| 3518 | * 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
|
---|
| 3519 | * and CSS code we can create an animation that will be picked up by AngularJS when an underlying directive performs an operation.
|
---|
| 3520 | *
|
---|
| 3521 | * The example below shows how an `enter` animation can be made possible on an element using `ng-if`:
|
---|
| 3522 | *
|
---|
| 3523 | * ```html
|
---|
| 3524 | * <div ng-if="bool" class="fade">
|
---|
| 3525 | * Fade me in out
|
---|
| 3526 | * </div>
|
---|
| 3527 | * <button ng-click="bool=true">Fade In!</button>
|
---|
| 3528 | * <button ng-click="bool=false">Fade Out!</button>
|
---|
| 3529 | * ```
|
---|
| 3530 | *
|
---|
| 3531 | * Notice the CSS class **fade**? We can now create the CSS transition code that references this class:
|
---|
| 3532 | *
|
---|
| 3533 | * ```css
|
---|
| 3534 | * /* The starting CSS styles for the enter animation */
|
---|
| 3535 | * .fade.ng-enter {
|
---|
| 3536 | * transition:0.5s linear all;
|
---|
| 3537 | * opacity:0;
|
---|
| 3538 | * }
|
---|
| 3539 | *
|
---|
| 3540 | * /* The finishing CSS styles for the enter animation */
|
---|
| 3541 | * .fade.ng-enter.ng-enter-active {
|
---|
| 3542 | * opacity:1;
|
---|
| 3543 | * }
|
---|
| 3544 | * ```
|
---|
| 3545 | *
|
---|
| 3546 | * 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
|
---|
| 3547 | * 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
|
---|
| 3548 | * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards.
|
---|
| 3549 | *
|
---|
| 3550 | * 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:
|
---|
| 3551 | *
|
---|
| 3552 | * ```css
|
---|
| 3553 | * /* now the element will fade out before it is removed from the DOM */
|
---|
| 3554 | * .fade.ng-leave {
|
---|
| 3555 | * transition:0.5s linear all;
|
---|
| 3556 | * opacity:1;
|
---|
| 3557 | * }
|
---|
| 3558 | * .fade.ng-leave.ng-leave-active {
|
---|
| 3559 | * opacity:0;
|
---|
| 3560 | * }
|
---|
| 3561 | * ```
|
---|
| 3562 | *
|
---|
| 3563 | * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class:
|
---|
| 3564 | *
|
---|
| 3565 | * ```css
|
---|
| 3566 | * /* there is no need to define anything inside of the destination
|
---|
| 3567 | * CSS class since the keyframe will take charge of the animation */
|
---|
| 3568 | * .fade.ng-leave {
|
---|
| 3569 | * animation: my_fade_animation 0.5s linear;
|
---|
| 3570 | * -webkit-animation: my_fade_animation 0.5s linear;
|
---|
| 3571 | * }
|
---|
| 3572 | *
|
---|
| 3573 | * @keyframes my_fade_animation {
|
---|
| 3574 | * from { opacity:1; }
|
---|
| 3575 | * to { opacity:0; }
|
---|
| 3576 | * }
|
---|
| 3577 | *
|
---|
| 3578 | * @-webkit-keyframes my_fade_animation {
|
---|
| 3579 | * from { opacity:1; }
|
---|
| 3580 | * to { opacity:0; }
|
---|
| 3581 | * }
|
---|
| 3582 | * ```
|
---|
| 3583 | *
|
---|
| 3584 | * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element.
|
---|
| 3585 | *
|
---|
| 3586 | * ### CSS Class-based Animations
|
---|
| 3587 | *
|
---|
| 3588 | * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different
|
---|
| 3589 | * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added
|
---|
| 3590 | * and removed.
|
---|
| 3591 | *
|
---|
| 3592 | * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class:
|
---|
| 3593 | *
|
---|
| 3594 | * ```html
|
---|
| 3595 | * <div ng-show="bool" class="fade">
|
---|
| 3596 | * Show and hide me
|
---|
| 3597 | * </div>
|
---|
| 3598 | * <button ng-click="bool=!bool">Toggle</button>
|
---|
| 3599 | *
|
---|
| 3600 | * <style>
|
---|
| 3601 | * .fade.ng-hide {
|
---|
| 3602 | * transition:0.5s linear all;
|
---|
| 3603 | * opacity:0;
|
---|
| 3604 | * }
|
---|
| 3605 | * </style>
|
---|
| 3606 | * ```
|
---|
| 3607 | *
|
---|
| 3608 | * 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
|
---|
| 3609 | * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest.
|
---|
| 3610 | *
|
---|
| 3611 | * 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
|
---|
| 3612 | * with CSS styles.
|
---|
| 3613 | *
|
---|
| 3614 | * ```html
|
---|
| 3615 | * <div ng-class="{on:onOff}" class="highlight">
|
---|
| 3616 | * Highlight this box
|
---|
| 3617 | * </div>
|
---|
| 3618 | * <button ng-click="onOff=!onOff">Toggle</button>
|
---|
| 3619 | *
|
---|
| 3620 | * <style>
|
---|
| 3621 | * .highlight {
|
---|
| 3622 | * transition:0.5s linear all;
|
---|
| 3623 | * }
|
---|
| 3624 | * .highlight.on-add {
|
---|
| 3625 | * background:white;
|
---|
| 3626 | * }
|
---|
| 3627 | * .highlight.on {
|
---|
| 3628 | * background:yellow;
|
---|
| 3629 | * }
|
---|
| 3630 | * .highlight.on-remove {
|
---|
| 3631 | * background:black;
|
---|
| 3632 | * }
|
---|
| 3633 | * </style>
|
---|
| 3634 | * ```
|
---|
| 3635 | *
|
---|
| 3636 | * We can also make use of CSS keyframes by placing them within the CSS classes.
|
---|
| 3637 | *
|
---|
| 3638 | *
|
---|
| 3639 | * ### CSS Staggering Animations
|
---|
| 3640 | * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a
|
---|
| 3641 | * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be
|
---|
| 3642 | * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for
|
---|
| 3643 | * the animation. The style property expected within the stagger class can either be a **transition-delay** or an
|
---|
| 3644 | * **animation-delay** property (or both if your animation contains both transitions and keyframe animations).
|
---|
| 3645 | *
|
---|
| 3646 | * ```css
|
---|
| 3647 | * .my-animation.ng-enter {
|
---|
| 3648 | * /* standard transition code */
|
---|
| 3649 | * transition: 1s linear all;
|
---|
| 3650 | * opacity:0;
|
---|
| 3651 | * }
|
---|
| 3652 | * .my-animation.ng-enter-stagger {
|
---|
| 3653 | * /* this will have a 100ms delay between each successive leave animation */
|
---|
| 3654 | * transition-delay: 0.1s;
|
---|
| 3655 | *
|
---|
| 3656 | * /* As of 1.4.4, this must always be set: it signals ngAnimate
|
---|
| 3657 | * to not accidentally inherit a delay property from another CSS class */
|
---|
| 3658 | * transition-duration: 0s;
|
---|
| 3659 | *
|
---|
| 3660 | * /* if you are using animations instead of transitions you should configure as follows:
|
---|
| 3661 | * animation-delay: 0.1s;
|
---|
| 3662 | * animation-duration: 0s; */
|
---|
| 3663 | * }
|
---|
| 3664 | * .my-animation.ng-enter.ng-enter-active {
|
---|
| 3665 | * /* standard transition styles */
|
---|
| 3666 | * opacity:1;
|
---|
| 3667 | * }
|
---|
| 3668 | * ```
|
---|
| 3669 | *
|
---|
| 3670 | * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations
|
---|
| 3671 | * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this
|
---|
| 3672 | * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
|
---|
| 3673 | * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired.
|
---|
| 3674 | *
|
---|
| 3675 | * The following code will issue the **ng-leave-stagger** event on the element provided:
|
---|
| 3676 | *
|
---|
| 3677 | * ```js
|
---|
| 3678 | * var kids = parent.children();
|
---|
| 3679 | *
|
---|
| 3680 | * $animate.leave(kids[0]); //stagger index=0
|
---|
| 3681 | * $animate.leave(kids[1]); //stagger index=1
|
---|
| 3682 | * $animate.leave(kids[2]); //stagger index=2
|
---|
| 3683 | * $animate.leave(kids[3]); //stagger index=3
|
---|
| 3684 | * $animate.leave(kids[4]); //stagger index=4
|
---|
| 3685 | *
|
---|
| 3686 | * window.requestAnimationFrame(function() {
|
---|
| 3687 | * //stagger has reset itself
|
---|
| 3688 | * $animate.leave(kids[5]); //stagger index=0
|
---|
| 3689 | * $animate.leave(kids[6]); //stagger index=1
|
---|
| 3690 | *
|
---|
| 3691 | * $scope.$digest();
|
---|
| 3692 | * });
|
---|
| 3693 | * ```
|
---|
| 3694 | *
|
---|
| 3695 | * Stagger animations are currently only supported within CSS-defined animations.
|
---|
| 3696 | *
|
---|
| 3697 | * ### The `ng-animate` CSS class
|
---|
| 3698 | *
|
---|
| 3699 | * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation.
|
---|
| 3700 | * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations).
|
---|
| 3701 | *
|
---|
| 3702 | * Therefore, animations can be applied to an element using this temporary class directly via CSS.
|
---|
| 3703 | *
|
---|
| 3704 | * ```css
|
---|
| 3705 | * .zipper.ng-animate {
|
---|
| 3706 | * transition:0.5s linear all;
|
---|
| 3707 | * }
|
---|
| 3708 | * .zipper.ng-enter {
|
---|
| 3709 | * opacity:0;
|
---|
| 3710 | * }
|
---|
| 3711 | * .zipper.ng-enter.ng-enter-active {
|
---|
| 3712 | * opacity:1;
|
---|
| 3713 | * }
|
---|
| 3714 | * .zipper.ng-leave {
|
---|
| 3715 | * opacity:1;
|
---|
| 3716 | * }
|
---|
| 3717 | * .zipper.ng-leave.ng-leave-active {
|
---|
| 3718 | * opacity:0;
|
---|
| 3719 | * }
|
---|
| 3720 | * ```
|
---|
| 3721 | *
|
---|
| 3722 | * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove
|
---|
| 3723 | * the CSS class once an animation has completed.)
|
---|
| 3724 | *
|
---|
| 3725 | *
|
---|
| 3726 | * ### The `ng-[event]-prepare` class
|
---|
| 3727 | *
|
---|
| 3728 | * This is a special class that can be used to prevent unwanted flickering / flash of content before
|
---|
| 3729 | * the actual animation starts. The class is added as soon as an animation is initialized, but removed
|
---|
| 3730 | * before the actual animation starts (after waiting for a $digest).
|
---|
| 3731 | * It is also only added for *structural* animations (`enter`, `move`, and `leave`).
|
---|
| 3732 | *
|
---|
| 3733 | * In practice, flickering can appear when nesting elements with structural animations such as `ngIf`
|
---|
| 3734 | * into elements that have class-based animations such as `ngClass`.
|
---|
| 3735 | *
|
---|
| 3736 | * ```html
|
---|
| 3737 | * <div ng-class="{red: myProp}">
|
---|
| 3738 | * <div ng-class="{blue: myProp}">
|
---|
| 3739 | * <div class="message" ng-if="myProp"></div>
|
---|
| 3740 | * </div>
|
---|
| 3741 | * </div>
|
---|
| 3742 | * ```
|
---|
| 3743 | *
|
---|
| 3744 | * It is possible that during the `enter` animation, the `.message` div will be briefly visible before it starts animating.
|
---|
| 3745 | * In that case, you can add styles to the CSS that make sure the element stays hidden before the animation starts:
|
---|
| 3746 | *
|
---|
| 3747 | * ```css
|
---|
| 3748 | * .message.ng-enter-prepare {
|
---|
| 3749 | * opacity: 0;
|
---|
| 3750 | * }
|
---|
| 3751 | * ```
|
---|
| 3752 | *
|
---|
| 3753 | * ### Animating between value changes
|
---|
| 3754 | *
|
---|
| 3755 | * Sometimes you need to animate between different expression states, whose values
|
---|
| 3756 | * don't necessary need to be known or referenced in CSS styles.
|
---|
| 3757 | * Unless possible with another {@link ngAnimate#directive-support "animation aware" directive},
|
---|
| 3758 | * that specific use case can always be covered with {@link ngAnimate.directive:ngAnimateSwap} as
|
---|
| 3759 | * can be seen in {@link ngAnimate.directive:ngAnimateSwap#examples this example}.
|
---|
| 3760 | *
|
---|
| 3761 | * Note that {@link ngAnimate.directive:ngAnimateSwap} is a *structural directive*, which means it
|
---|
| 3762 | * creates a new instance of the element (including any other/child directives it may have) and
|
---|
| 3763 | * links it to a new scope every time *swap* happens. In some cases this might not be desirable
|
---|
| 3764 | * (e.g. for performance reasons, or when you wish to retain internal state on the original
|
---|
| 3765 | * element instance).
|
---|
| 3766 | *
|
---|
| 3767 | * ## JavaScript-based Animations
|
---|
| 3768 | *
|
---|
| 3769 | * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared
|
---|
| 3770 | * 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
|
---|
| 3771 | * `module.animation()` module function we can register the animation.
|
---|
| 3772 | *
|
---|
| 3773 | * Let's see an example of a enter/leave animation using `ngRepeat`:
|
---|
| 3774 | *
|
---|
| 3775 | * ```html
|
---|
| 3776 | * <div ng-repeat="item in items" class="slide">
|
---|
| 3777 | * {{ item }}
|
---|
| 3778 | * </div>
|
---|
| 3779 | * ```
|
---|
| 3780 | *
|
---|
| 3781 | * 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`:
|
---|
| 3782 | *
|
---|
| 3783 | * ```js
|
---|
| 3784 | * myModule.animation('.slide', [function() {
|
---|
| 3785 | * return {
|
---|
| 3786 | * // make note that other events (like addClass/removeClass)
|
---|
| 3787 | * // have different function input parameters
|
---|
| 3788 | * enter: function(element, doneFn) {
|
---|
| 3789 | * jQuery(element).fadeIn(1000, doneFn);
|
---|
| 3790 | *
|
---|
| 3791 | * // remember to call doneFn so that AngularJS
|
---|
| 3792 | * // knows that the animation has concluded
|
---|
| 3793 | * },
|
---|
| 3794 | *
|
---|
| 3795 | * move: function(element, doneFn) {
|
---|
| 3796 | * jQuery(element).fadeIn(1000, doneFn);
|
---|
| 3797 | * },
|
---|
| 3798 | *
|
---|
| 3799 | * leave: function(element, doneFn) {
|
---|
| 3800 | * jQuery(element).fadeOut(1000, doneFn);
|
---|
| 3801 | * }
|
---|
| 3802 | * }
|
---|
| 3803 | * }]);
|
---|
| 3804 | * ```
|
---|
| 3805 | *
|
---|
| 3806 | * The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as
|
---|
| 3807 | * greensock.js and velocity.js.
|
---|
| 3808 | *
|
---|
| 3809 | * If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define
|
---|
| 3810 | * our animations inside of the same registered animation, however, the function input arguments are a bit different:
|
---|
| 3811 | *
|
---|
| 3812 | * ```html
|
---|
| 3813 | * <div ng-class="color" class="colorful">
|
---|
| 3814 | * this box is moody
|
---|
| 3815 | * </div>
|
---|
| 3816 | * <button ng-click="color='red'">Change to red</button>
|
---|
| 3817 | * <button ng-click="color='blue'">Change to blue</button>
|
---|
| 3818 | * <button ng-click="color='green'">Change to green</button>
|
---|
| 3819 | * ```
|
---|
| 3820 | *
|
---|
| 3821 | * ```js
|
---|
| 3822 | * myModule.animation('.colorful', [function() {
|
---|
| 3823 | * return {
|
---|
| 3824 | * addClass: function(element, className, doneFn) {
|
---|
| 3825 | * // do some cool animation and call the doneFn
|
---|
| 3826 | * },
|
---|
| 3827 | * removeClass: function(element, className, doneFn) {
|
---|
| 3828 | * // do some cool animation and call the doneFn
|
---|
| 3829 | * },
|
---|
| 3830 | * setClass: function(element, addedClass, removedClass, doneFn) {
|
---|
| 3831 | * // do some cool animation and call the doneFn
|
---|
| 3832 | * }
|
---|
| 3833 | * }
|
---|
| 3834 | * }]);
|
---|
| 3835 | * ```
|
---|
| 3836 | *
|
---|
| 3837 | * ## CSS + JS Animations Together
|
---|
| 3838 | *
|
---|
| 3839 | * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of AngularJS,
|
---|
| 3840 | * 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
|
---|
| 3841 | * charge of the animation**:
|
---|
| 3842 | *
|
---|
| 3843 | * ```html
|
---|
| 3844 | * <div ng-if="bool" class="slide">
|
---|
| 3845 | * Slide in and out
|
---|
| 3846 | * </div>
|
---|
| 3847 | * ```
|
---|
| 3848 | *
|
---|
| 3849 | * ```js
|
---|
| 3850 | * myModule.animation('.slide', [function() {
|
---|
| 3851 | * return {
|
---|
| 3852 | * enter: function(element, doneFn) {
|
---|
| 3853 | * jQuery(element).slideIn(1000, doneFn);
|
---|
| 3854 | * }
|
---|
| 3855 | * }
|
---|
| 3856 | * }]);
|
---|
| 3857 | * ```
|
---|
| 3858 | *
|
---|
| 3859 | * ```css
|
---|
| 3860 | * .slide.ng-enter {
|
---|
| 3861 | * transition:0.5s linear all;
|
---|
| 3862 | * transform:translateY(-100px);
|
---|
| 3863 | * }
|
---|
| 3864 | * .slide.ng-enter.ng-enter-active {
|
---|
| 3865 | * transform:translateY(0);
|
---|
| 3866 | * }
|
---|
| 3867 | * ```
|
---|
| 3868 | *
|
---|
| 3869 | * 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
|
---|
| 3870 | * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from
|
---|
| 3871 | * our own JS-based animation code:
|
---|
| 3872 | *
|
---|
| 3873 | * ```js
|
---|
| 3874 | * myModule.animation('.slide', ['$animateCss', function($animateCss) {
|
---|
| 3875 | * return {
|
---|
| 3876 | * enter: function(element) {
|
---|
| 3877 | * // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`.
|
---|
| 3878 | * return $animateCss(element, {
|
---|
| 3879 | * event: 'enter',
|
---|
| 3880 | * structural: true
|
---|
| 3881 | * });
|
---|
| 3882 | * }
|
---|
| 3883 | * }
|
---|
| 3884 | * }]);
|
---|
| 3885 | * ```
|
---|
| 3886 | *
|
---|
| 3887 | * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework.
|
---|
| 3888 | *
|
---|
| 3889 | * The `$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
|
---|
| 3890 | * 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
|
---|
| 3891 | * data into `$animateCss` directly:
|
---|
| 3892 | *
|
---|
| 3893 | * ```js
|
---|
| 3894 | * myModule.animation('.slide', ['$animateCss', function($animateCss) {
|
---|
| 3895 | * return {
|
---|
| 3896 | * enter: function(element) {
|
---|
| 3897 | * return $animateCss(element, {
|
---|
| 3898 | * event: 'enter',
|
---|
| 3899 | * structural: true,
|
---|
| 3900 | * addClass: 'maroon-setting',
|
---|
| 3901 | * from: { height:0 },
|
---|
| 3902 | * to: { height: 200 }
|
---|
| 3903 | * });
|
---|
| 3904 | * }
|
---|
| 3905 | * }
|
---|
| 3906 | * }]);
|
---|
| 3907 | * ```
|
---|
| 3908 | *
|
---|
| 3909 | * Now we can fill in the rest via our transition CSS code:
|
---|
| 3910 | *
|
---|
| 3911 | * ```css
|
---|
| 3912 | * /* the transition tells ngAnimate to make the animation happen */
|
---|
| 3913 | * .slide.ng-enter { transition:0.5s linear all; }
|
---|
| 3914 | *
|
---|
| 3915 | * /* this extra CSS class will be absorbed into the transition
|
---|
| 3916 | * since the $animateCss code is adding the class */
|
---|
| 3917 | * .maroon-setting { background:red; }
|
---|
| 3918 | * ```
|
---|
| 3919 | *
|
---|
| 3920 | * And `$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.
|
---|

|
---|
| 3924 | * ## Animation Anchoring (via `ng-animate-ref`)
|
---|
| 3925 | *
|
---|
| 3926 | * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between
|
---|
| 3927 | * structural areas of an application (like views) by pairing up elements using an attribute
|
---|
| 3928 | * called `ng-animate-ref`.
|
---|
| 3929 | *
|
---|
| 3930 | * Let's say for example we have two views that are managed by `ng-view` and we want to show
|
---|
| 3931 | * that there is a relationship between two components situated in within these views. By using the
|
---|
| 3932 | * `ng-animate-ref` attribute we can identify that the two components are paired together and we
|
---|
| 3933 | * can then attach an animation, which is triggered when the view changes.
|
---|
| 3934 | *
|
---|
| 3935 | * Say for example we have the following template code:
|
---|
| 3936 | *
|
---|
| 3937 | * ```html
|
---|
| 3938 | * <!-- index.html -->
|
---|
| 3939 | * <div ng-view class="view-animation">
|
---|
| 3940 | * </div>
|
---|
| 3941 | *
|
---|
| 3942 | * <!-- home.html -->
|
---|
| 3943 | * <a href="#/banner-page">
|
---|
| 3944 | * <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
|
---|
| 3945 | * </a>
|
---|
| 3946 | *
|
---|
| 3947 | * <!-- banner-page.html -->
|
---|
| 3948 | * <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
|
---|
| 3949 | * ```
|
---|
| 3950 | *
|
---|
| 3951 | * Now, when the view changes (once the link is clicked), ngAnimate will examine the
|
---|
| 3952 | * HTML contents to see if there is a match reference between any components in the view
|
---|
| 3953 | * that is leaving and the view that is entering. It will scan both the view which is being
|
---|
| 3954 | * removed (leave) and inserted (enter) to see if there are any paired DOM elements that
|
---|
| 3955 | * contain a matching ref value.
|
---|
| 3956 | *
|
---|
| 3957 | * The two images match since they share the same ref value. ngAnimate will now create a
|
---|
| 3958 | * transport element (which is a clone of the first image element) and it will then attempt
|
---|
| 3959 | * to animate to the position of the second image element in the next view. For the animation to
|
---|
| 3960 | * work a special CSS class called `ng-anchor` will be added to the transported element.
|
---|
| 3961 | *
|
---|
| 3962 | * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then
|
---|
| 3963 | * ngAnimate will handle the entire transition for us as well as the addition and removal of
|
---|
| 3964 | * any changes of CSS classes between the elements:
|
---|
| 3965 | *
|
---|
| 3966 | * ```css
|
---|
| 3967 | * .banner.ng-anchor {
|
---|
| 3968 | * /* this animation will last for 1 second since there are
|
---|
| 3969 | * two phases to the animation (an `in` and an `out` phase) */
|
---|
| 3970 | * transition:0.5s linear all;
|
---|
| 3971 | * }
|
---|
| 3972 | * ```
|
---|
| 3973 | *
|
---|
| 3974 | * We also **must** include animations for the views that are being entered and removed
|
---|
| 3975 | * (otherwise anchoring wouldn't be possible since the new view would be inserted right away).
|
---|
| 3976 | *
|
---|
| 3977 | * ```css
|
---|
| 3978 | * .view-animation.ng-enter, .view-animation.ng-leave {
|
---|
| 3979 | * transition:0.5s linear all;
|
---|
| 3980 | * position:fixed;
|
---|
| 3981 | * left:0;
|
---|
| 3982 | * top:0;
|
---|
| 3983 | * width:100%;
|
---|
| 3984 | * }
|
---|
| 3985 | * .view-animation.ng-enter {
|
---|
| 3986 | * transform:translateX(100%);
|
---|
| 3987 | * }
|
---|
| 3988 | * .view-animation.ng-leave,
|
---|
| 3989 | * .view-animation.ng-enter.ng-enter-active {
|
---|
| 3990 | * transform:translateX(0%);
|
---|
| 3991 | * }
|
---|
| 3992 | * .view-animation.ng-leave.ng-leave-active {
|
---|
| 3993 | * transform:translateX(-100%);
|
---|
| 3994 | * }
|
---|
| 3995 | * ```
|
---|
| 3996 | *
|
---|
| 3997 | * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur:
|
---|
| 3998 | * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away
|
---|
| 3999 | * from its origin. Once that animation is over then the `in` stage occurs which animates the
|
---|
| 4000 | * element to its destination. The reason why there are two animations is to give enough time
|
---|
| 4001 | * for the enter animation on the new element to be ready.
|
---|
| 4002 | *
|
---|
| 4003 | * The example above sets up a transition for both the in and out phases, but we can also target the out or
|
---|
| 4004 | * in phases directly via `ng-anchor-out` and `ng-anchor-in`.
|
---|
| 4005 | *
|
---|
| 4006 | * ```css
|
---|
| 4007 | * .banner.ng-anchor-out {
|
---|
| 4008 | * transition: 0.5s linear all;
|
---|
| 4009 | *
|
---|
| 4010 | * /* the scale will be applied during the out animation,
|
---|
| 4011 | * but will be animated away when the in animation runs */
|
---|
| 4012 | * transform: scale(1.2);
|
---|
| 4013 | * }
|
---|
| 4014 | *
|
---|
| 4015 | * .banner.ng-anchor-in {
|
---|
| 4016 | * transition: 1s linear all;
|
---|
| 4017 | * }
|
---|
| 4018 | * ```
|
---|
| 4019 | *
|
---|
| 4020 | *
|
---|
| 4021 | *
|

|
---|
| 4129 | * ### How is the element transported?
|
---|
| 4130 | *
|
---|
| 4131 | * When an anchor animation occurs, ngAnimate will clone the starting element and position it exactly where the starting
|
---|
| 4132 | * element is located on screen via absolute positioning. The cloned element will be placed inside of the root element
|
---|
| 4133 | * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The
|
---|
| 4134 | * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match
|
---|
| 4135 | * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied
|
---|
| 4136 | * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class
|
---|
| 4137 | * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element
|
---|
| 4138 | * will become visible since the shim class will be removed.
|
---|
| 4139 | *
|
---|
| 4140 | * ### How is the morphing handled?
|
---|
| 4141 | *
|
---|
| 4142 | * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out
|
---|
| 4143 | * what CSS classes differ between the starting element and the destination element. These different CSS classes
|
---|
| 4144 | * will be added/removed on the anchor element and a transition will be applied (the transition that is provided
|
---|
| 4145 | * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will
|
---|
| 4146 | * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that
|
---|
| 4147 | * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since
|
---|
| 4148 | * the cloned element is placed inside of root element which is likely close to the body element).
|
---|
| 4149 | *
|
---|
| 4150 | * Note that if the root element is on the `<html>` element then the cloned node will be placed inside of body.
|
---|
| 4151 | *
|
---|
| 4152 | *
|
---|
| 4153 | * ## Using $animate in your directive code
|
---|
| 4154 | *
|
---|
| 4155 | * So far we've explored how to feed in animations into an AngularJS application, but how do we trigger animations within our own directives in our application?
|
---|
| 4156 | * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's
|
---|
| 4157 | * imagine we have a greeting box that shows and hides itself when the data changes
|
---|
| 4158 | *
|
---|
| 4159 | * ```html
|
---|
| 4160 | * <greeting-box active="onOrOff">Hi there</greeting-box>
|
---|
| 4161 | * ```
|
---|
| 4162 | *
|
---|
| 4163 | * ```js
|
---|
| 4164 | * ngModule.directive('greetingBox', ['$animate', function($animate) {
|
---|
| 4165 | * return function(scope, element, attrs) {
|
---|
| 4166 | * attrs.$observe('active', function(value) {
|
---|
| 4167 | * value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on');
|
---|
| 4168 | * });
|
---|
| 4169 | * });
|
---|
| 4170 | * }]);
|
---|
| 4171 | * ```
|
---|
| 4172 | *
|
---|
| 4173 | * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element
|
---|
| 4174 | * in our HTML code then we can trigger a CSS or JS animation to happen.
|
---|
| 4175 | *
|
---|
| 4176 | * ```css
|
---|
| 4177 | * /* normally we would create a CSS class to reference on the element */
|
---|
| 4178 | * greeting-box.on { transition:0.5s linear all; background:green; color:white; }
|
---|
| 4179 | * ```
|
---|
| 4180 | *
|
---|
| 4181 | * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's
|
---|
| 4182 | * possible be sure to visit the {@link ng.$animate $animate service API page}.
|
---|
| 4183 | *
|
---|
| 4184 | *
|
---|
| 4185 | * ## Callbacks and Promises
|
---|
| 4186 | *
|
---|
| 4187 | * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger
|
---|
| 4188 | * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has
|
---|
| 4189 | * ended by chaining onto the returned promise that animation method returns.
|
---|
| 4190 | *
|
---|
| 4191 | * ```js
|
---|
| 4192 | * // somewhere within the depths of the directive
|
---|
| 4193 | * $animate.enter(element, parent).then(function() {
|
---|
| 4194 | * //the animation has completed
|
---|
| 4195 | * });
|
---|
| 4196 | * ```
|
---|
| 4197 | *
|
---|
| 4198 | * (Note that earlier versions of AngularJS prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case
|
---|
| 4199 | * anymore.)
|
---|
| 4200 | *
|
---|
| 4201 | * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering
|
---|
| 4202 | * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view
|
---|
| 4203 | * routing controller to hook into that:
|
---|
| 4204 | *
|
---|
| 4205 | * ```js
|
---|
| 4206 | * ngModule.controller('HomePageController', ['$animate', function($animate) {
|
---|
| 4207 | * $animate.on('enter', ngViewElement, function(element) {
|
---|
| 4208 | * // the animation for this route has completed
|
---|
| 4209 | * }]);
|
---|
| 4210 | * }])
|
---|
| 4211 | * ```
|
---|
| 4212 | *
|
---|
| 4213 | * (Note that you will need to trigger a digest within the callback to get AngularJS to notice any scope-related changes.)
