Properties

属性继承其父级Event.

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