SVGAnimationElement: repeatEvent event

The repeatEvent event of the SVGAnimationElement interface is fired when the element's local timeline repeats. It will be fired each time the element repeats, after the first iteration.

Note: Associated with the repeatEvent event is an integer that indicates which repeat iteration is beginning; this can be found in the detail property of the event object. The value is a 0-based integer, but the repeat event is not raised for the first iteration and so the observed values will be >= 1. This is supported in Firefox, but not in Chrome.

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>

<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');

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

Event handler property equivalent

Note that you can also create an event listener for the repeat event using the onrepeat event handler property:

animateElem.onrepeat = () => {
  console.log('repeatEvent fired');
}
