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.

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');
}
