The animationend
event is fired when a CSS Animation has completed. If the animation aborts before reaching completion, such as if the element is removed from the DOM or the animation is removed from the element, the animationend
event is not fired.
Use the event name in methods like addEventListener()
, or set an event handler property.
addEventListener("animationend", (event) => { })
onanimationend = (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 example gets an element that's being animated and listens for the animationend
event:
const animated = document.querySelector(".animated");
animated.addEventListener("animationend", () => {
console.log("Animation ended");
});
The same, but using the onanimationend
event handler property:
const animated = document.querySelector(".animated");
animated.onanimationend = () => {
console.log("Animation ended");
};
