Element: animationcancel event

The animationcancel event is fired when a CSS Animation unexpectedly aborts. In other words, any time it stops running without sending an animationend event. This might happen when the animation-name is changed such that the animation is removed, or when the animating node is hidden using CSS. Therefore, either directly or because any of its containing nodes are hidden.

An event handler for this event can be added by setting the onanimationcancel property, or using addEventListener().


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

addEventListener("animationcancel", (event) => {});

onanimationcancel = (event) => {};

Event type

Event properties

Also inherits properties from its parent Event.

AnimationEvent.animationName Read only

A string containing the value of the animation-name that generated the animation.

AnimationEvent.elapsedTime Read only

A float giving the amount of time the animation has been running, in seconds, when this event fired, excluding any time the animation was paused. For an animationstart event, elapsedTime is 0.0 unless there was a negative value for animation-delay, in which case the event will be fired with elapsedTime containing (-1 * delay).

AnimationEvent.pseudoElement Read only

A string, starting with '::', containing the name of the pseudo-element the animation runs on. If the animation doesn't run on a pseudo-element but on the element, an empty string: ''.


This code gets an element that's currently being animated and adds a listener to the animationcancel event. It then sets the element's display property to none, which will trigger the animationcancel event.

const animated = document.querySelector(".animated");

animated.addEventListener("animationcancel", () => {
  console.log("Animation canceled");

animated.style.display = "none";

The same, but using the onanimationcancel property instead of addEventListener():

const animated = document.querySelector(".animated");
animated.onanimationcancel = () => {
  console.log("Animation canceled");

animated.style.display = "none";

animation.addEventListener("animationcancel", () => {

applyAnimation.addEventListener("click", () => {
  animationEventLog.textContent = "";
  iterationCount = 0;
  const active = animation.classList.contains("active");
  applyAnimation.textContent = active
    ? "Cancel animation"
    : "Activate animation";
