The pause() method of the Web Animations API's Animation interface suspends playback of the animation.
pause()None.
None.
InvalidStateError DOMExceptionThrown if the animation's currentTime is unresolved (perhaps it hasn't started playing yet), and the end time of the animation is positive infinity.
Animation.pause() is used many times in the Alice in Web Animations API Land Growing/Shrinking Alice Game, largely because animations created with the Element.animate() method immediately start playing and must be paused manually if you want to avoid that:
// animation of the cupcake slowly getting eaten up
const nommingCake = document
.getElementById("eat-me_sprite")
.animate(
[{ transform: "translateY(0)" }, { transform: "translateY(-80%)" }],
{
fill: "forwards",
easing: "steps(4, end)",
duration: aliceChange.effect.timing.duration / 2,
},
);
// doesn't actually need to be eaten until a click event, so pause it initially:
nommingCake.pause();Additionally, when resetting:
// An all-purpose function to pause the animations on Alice, the cupcake, and the bottle that reads "drink me."
const stopPlayingAlice = () => {
aliceChange.pause();
nommingCake.pause();
drinking.pause();
};
// When the user releases the cupcake or the bottle, pause the animations.
cake.addEventListener("mouseup", stopPlayingAlice);
bottle.addEventListener("mouseup", stopPlayingAlice);Animation for other methods and properties you can use to control web page animation.Animation.reverse() to play an animation backwards.Animation.finish() to finish an animation.Animation.cancel() to cancel an animation.
