Animation: finish event

The finish event of the Animation interface is fired when the animation finishes playing, either when the animation completes naturally, or when the Animation.finish() method is called to immediately cause the animation to finish up.

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener('finish', event => { })
onfinish = event => { }

An AnimationPlaybackEvent. Inherits from Event.

In addition to the properties listed below, properties from the parent interface, Event, are available.

AnimationPlaybackEvent.currentTime Read only

The current time of the animation that generated the event.

AnimationPlaybackEvent.timelineTime Read only

The time value of the timeline of the animation that generated the event.

Animation.onfinish is used several times in the Alice in Web Animations API Land Growing/Shrinking Alice Game. Here is one instance where we add pointer events back to an element after its opacity animation has faded it in:

// Add an animation to the game's ending credits
var endingUI = document.getElementById("ending-ui");
var bringUI = endingUI.animate(keysFade, timingFade);

// Pause said animation's credits
bringUI.pause();

// This function removes pointer events on the credits.
hide(endingUI);

// When the credits are later faded in,
// we re-add the pointer events when they're done
bringUI.onfinish = event => {endingUI.style.pointerEvents = 'auto';};
