KeyframeEffect.target - Web APIs 编辑

Experimental

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The target property of a KeyframeEffect interface represents the element or pseudo-element being animated. It may be null for animations that do not target a specific element. It performs as both a getter and a setter, except with animations and transitions generated by CSS.

Syntax

var targetElement = document.getElementById("elementToAnimate");

var keyframes = new KeyframeEffect( targetElement, keyframeBlock, timingOptions );

// returns #elementToAnimate
keyframes.target;

// assigns keyframes a new target
keyframes.target = newTargetElement;

Value

An Element, CSSPseudoElement, or null.

Examples

In the Follow the White Rabbit example, whiteRabbit sets the target element to be animated:

var whiteRabbit = document.getElementById("rabbit");

var rabbitDownKeyframes = new KeyframeEffect(
  whiteRabbit,
  [
    { transform: 'translateY(0%)' },
    { transform: 'translateY(100%)' }
  ],
  { duration: 3000, fill: 'forwards' }
);

// returns <div id="rabbit">Click the rabbit's ears!</div>
rabbitDownKeyframes.target;
