This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The AnimationEvent interface represents events providing information related to animations.

Constructor

AnimationEvent()
Creates an AnimationEvent event with the given parameters.

Properties

AnimationEvent.animationName Read only
Is a DOMString containing the value of the animation-name CSS property associated with the transition.
AnimationEvent.elapsedTime Read only
Is 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
Is a DOMString, 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: ''.
