animationiteration event is fired when an iteration of a CSS Animation ends, and another one begins. This event does not occur at the same time as the animationend event, and therefore does not occur for animations with an animation-iteration-count of one.

冒泡	Yes

接口	`AnimationEvent`
事件处理程序特性	`onanimationiteration`

The original target for this event is the 元素 that had the animation applied. You can listen for this event on the Document interface to handle it in the capture or bubbling phases. For full details on this event please see the page on HTMLElement: animationiteration .

范例

This code uses animationiteration to keep track of the number of iterations an animation has completed:

let iterationCount = 0;
document.addEventListener('animationiteration', () => {
  iterationCount++;
  console.log(`Animation iteration count: ${iterationCount}`);
});

一样，但使用 onanimationiteration 事件处理程序特性：

let iterationCount = 0;
document.onanimationiteration = () => {
  iterationCount++;
  console.log(`Animation iteration count: ${iterationCount}`);
};

See a live example of this event.
