Animation.finished - Web APIs 编辑

Experimental

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The Animation.finished read-only property of the Web Animations API returns a Promise which resolves once the animation has finished playing.

Every time the animation leaves the finished play state (that is, when it starts playing again), a new Promise is created for this property. The new Promise will resolve once the new animation sequence has completed.

Syntax

var animationsPromise = Animation.finished;

Value

A Promise object which will resolve once the animation has finished running.

Examples

The following code waits until all animations running on the element elem have finished, then deletes the element from the DOM tree:

Promise.all(
  elem.getAnimations().map(
    function(animation) {
      return animation.finished
    }
  )
).then(
  function() {
    return elem.remove();
  }
);
