Animation.onfinish

The Animation interface's onfinish property (from the Web Animations API) is the event handler for the finish event. This event is sent when the animation finishes playing.

The finish event occurs when the animation completes naturally, as well as when the Animation.finish() method is called to immediately cause the animation to finish up.

Syntax

var finishHandler = Animation.onfinish;

Animation.onfinish = finishHandler;

Value

A function to be called to handle the finish event, or null if no finish event handler is set.

Examples

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 = function() {
  endingUI.style.pointerEvents = 'auto';
};
