The getAnimations()
method of the ShadowRoot
interface returns an array of all Animation
objects currently in effect whose target elements are descendants of the shadow tree. This array includes CSS Animations, CSS Transitions, and Web Animations.
An Array
of Animation
objects, each representing one animation currently associated with elements which are descendants of the ShadowRoot
on which it's called.
The following code snippet will slow down all animations in a shadow tree by halving their Animation.playbackRate
.
let customElem = document.querySelector("my-shadow-dom-element");
let shadow = customElem.shadowRoot;
shadow.getAnimations().forEach((animation) => {
animation.playbackRate *= 0.5;
});
