onfinish
property (from the
Web 动画 API
) is the event handler for the
finish
event. This event is sent when the animation finishes playing.
finish
event occurs when the animation completes naturally, as well as when the
Animation.finish()
method is called to immediately cause the animation to finish up.
"paused"
play state supersedes the
"finished"
play state; if the animation is both paused and finished, the
"paused"
state is the one that will be reported. You can force the animation into the
"finished"
state by setting its
startTime
to
document.timeline.currentTime - (
动画
.currentTime *
动画
.playbackRate)
.
var finishHandler = Animation.onfinish; Animation.onfinish = finishHandler;
A function to be called to handle the
finish
event, or
null
if no
finish
event handler is set.
Animation.onfinish
is used several times in the Alice in Web Animations API Land
Growing/Shrinking Alice Game
. Here is one instance where we add pointer events back to an element after its opacity animation has faded it in:
// Add an animation to the game's ending credits
var endingUI = document.getElementById("ending-ui");
var bringUI = endingUI.animate(keysFade, timingFade);
// Pause said animation's credits
bringUI.pause();
// This function removes pointer events on the credits.
hide(endingUI);
// When the credits are later faded in,
// we re-add the pointer events when they're done
bringUI.onfinish = function() {
endingUI.style.pointerEvents = 'auto';
};
