HTMLElement: transitioncancel event

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The transitioncancel event is fired when a CSS transition is canceled.

See GlobalEventHandlers.ontransitioncancel for more information.

Bubbles Yes
Cancelable No
Interface TransitionEvent
Event handler property GlobalEventHandlers.ontransitioncancel


This code gets an element that has a transition defined and adds a listener to the transitioncancel event:

const transition = document.querySelector('.transition');

transition.addEventListener('transitioncancel', () => {
  console.log('Transition canceled');

The same, but using the ontransitioncancel property instead of addEventListener():

const transition = document.querySelector('.transition');

transition.ontransitioncancel = () => {
  console.log('Transition canceled');

Live example

In the following example, we have a simple <div> element, styled with a transition that includes a delay:

<div class="transition"></div>
<div class="message"></div>
.transition {
  width: 100px;
  height: 100px;
  background: rgba(255,0,0,1);
  transition-property: transform background;
  transition-duration: 2s;
  transition-delay: 2s;

.transition:hover {
  transform: rotate(90deg);
  background: rgba(255,0,0,0);

To this, we'll add some JavaScript to indicate that the transitionstart, transitionrun, transitioncancel and transitionend events fire. In this example, to cancel the transition, stop hovering over the transitioning box before the transition ends. For the transition end event to fire, stay hovered over the transition until the transition ends.

const message = document.querySelector('.message');
const el = document.querySelector('.transition');

el.addEventListener('transitionrun', function() {
  message.textContent = 'transitionrun fired';

el.addEventListener('transitionstart', function() {
  message.textContent = 'transitionstart fired';

el.addEventListener('transitioncancel', function() {
  message.textContent = 'transitioncancel fired';

el.addEventListener('transitionend', function() {
  message.textContent = 'transitionend fired';

The transitioncancel event is fired if the transition is cancelled in either direction after the transitionrun event occurs and before the transitionend is fired.

If there is no transition delay or duration, if both are 0s or neither is declared, there is no transition, and none of the transition events are fired.

If the transitioncancel event is fired, the transitionend event will not fire.
