Animation.pause()

The Animation.pause() method of the Animation interface suspends playback of the animation. 

Syntax

animation.pause(); 

Parameters

None.

Return Value

None.

Exceptions

Throws an InvalidStateError if the animation's currentTime is unresolved (perhaps it hasn't started playing yet) and the end time of the animation is positive infinity.

Example

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
var 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."
var stopPlayingAlice = function() {
  aliceChange.pause();
  nommingCake.pause();
  drinking.pause();
};

// When the user releases the cupcake or the bottle, pause the animations.
cake.addEventListener("mouseup", stopPlayingAlice, false);
bottle.addEventListener("mouseup", stopPlayingAlice, false);
