The getAnimations() method of the Element interface (specified on the Animatable mixin) returns an array of all Animation objects affecting this element or which are scheduled to do so in future. It can optionally return Animation objects for descendant elements too.

options Optional

An options object containing the following property:

subtree

A boolean value which, if true, causes animations that target descendants of Element to be returned as well. This includes animations that target any CSS pseudo-elements attached to Element or one of its descendants. Defaults to false.

An Array of Animation objects, each representing an animation currently targeting the Element on which this method is called, or one of its descendant elements if { subtree: true } is specified.

The following code snippet will wait for all animations on elem and its descendants to finish before removing the element from the document.

Promise.all(
  elem.getAnimations({ subtree: true }).map((animation) => animation.finished),
).then(() => elem.remove());
