KeyframeEffectReadOnly.target

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

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.

Syntax

JavaScript
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 or null.

Examples

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

JavaScript
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;
