The target
property of a KeyframeEffectReadOnly
or 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.
Note: For KeyframeEffect
, this property is both a getter and a setter. For KeyframeEffectReadOnly
, it is read-only.
var targetElement = document.getElementById("elementToAnimate"); var keyframes = new KeyframeEffect( targetElement, keyframeBlock, timingOptions ); // returns #elementToAnimate keyframes.target; // assigns keyframes a new target keyframes.target = newTargetElement;
An Element
or null
.
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;
