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
