Element: transitioncancel event

{{APIRef}}

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

Syntax

Use the event name in methods like {{domxref("EventTarget.addEventListener", "addEventListener()")}} , or set an event handler property.

addEventListener("transitioncancel", (event) => { })

ontransitioncancel = (event) => { }

Event type

A {{domxref("TransitionEvent")}} . Inherits from {{domxref("Event")}} .

{{InheritanceDiagram("TransitionEvent")}}

Event properties

Also inherits properties from its parent {{domxref("Event")}} .

{{domxref("TransitionEvent.propertyName")}} {{ReadOnlyInline}}
- : A string containing the name CSS property associated with the transition.
{{domxref("TransitionEvent.elapsedTime")}} {{ReadOnlyInline}}
- : A float giving the amount of time the transition has been running, in seconds, when this event fired. This value is not affected by the {{cssxref("transition-delay")}} property.
{{domxref("TransitionEvent.pseudoElement")}} {{ReadOnlyInline}}
- : A string, starting with ::, containing the name of the pseudo-element the animation runs on. If the transition doesn’t run on a pseudo-element but on the element, an empty string: ''.

Examples

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 {{htmlelement("div")}} element, styled with a transition that includes a delay:

<div class="transition"></div>
<div class="message"></div>

.transition {
  width: 100px;
  height: 100px;
  background: red;
  transition-property: transform, background;
  transition-duration: 2s;
  transition-delay: 2s;
}

.transition:hover {
  transform: rotate(90deg);
  background: transparent;
}

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", () => {
  message.textContent = "transitionrun fired";
});

el.addEventListener("transitionstart", () => {
  message.textContent = "transitionstart fired";
});

el.addEventListener("transitioncancel", () => {
  message.textContent = "transitioncancel fired";
});

el.addEventListener("transitionend", () => {
  message.textContent = "transitionend fired";
});

{{ EmbedLiveSample('Live_example', '100%', '150px') }}

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.
