SVGAnimationElement: endEvent event - Web APIs 编辑

The endEvent event of the SVGAnimationElement interface is fired when at the active end of the animation is reached.

Note: This event is not raised at the simple end of each animation repeat. This event may be raised both in the course of normal (i.e. scheduled or interactive) timeline play, as well as in the case that the element was ended with a DOM method.

Examples

Animated circle

<svg xmlns="http://www.w3.org/2000/svg" width="300px" height="100px">
  <title>SVG SMIL Animate with Path</title>
  <circle cx="0" cy="50" r="50" fill="blue" stroke="black" stroke-width="1">
    <animateMotion
       path="M 0 0 H 300 Z"
       dur="5s" repeatCount="indefinite" />
  </circle>
</svg>

<hr>

<button>Stop animation</button>

<ul>

</ul>

ul {
  height: 100px;
  border: 1px solid #ddd;
  overflow-y: scroll;
  padding: 10px 30px;
}

let svgElem = document.querySelector('svg');
let animateElem = document.querySelector('animateMotion');
let list = document.querySelector('ul');
let btn = document.querySelector('button');

animateElem.addEventListener('beginEvent', () => {
  let listItem = document.createElement('li');
  listItem.textContent = 'beginEvent fired';
  list.appendChild(listItem);
})

animateElem.addEventListener('endEvent', () => {
  let listItem = document.createElement('li');
  listItem.textContent = 'endEvent fired';
  list.appendChild(listItem);
})

animateElem.addEventListener('repeatEvent', (e) => {
  let listItem = document.createElement('li');
  let msg = 'repeatEvent fired';
  if(e.detail) {
    msg += '; repeat number: ' + e.detail;
  }
  listItem.textContent = msg;
  list.appendChild(listItem);
})

btn.addEventListener('click', () => {
  btn.disabled = true;
  animateElem.setAttribute('repeatCount', '1');
})

Event handler property equivalent

Note that you can also create an event listener for the end event using the onend event handler property:

animateElem.onend = () => {
  console.log('endEvent fired');
}
