transitionend
event is fired when a
CSS transition
has completed. In the case where a transition is removed before completion, such as if the
transition-property
is removed or
display
被设为
none
, then the event will not be generated.

transitionend
event is fired in both directions - as it finishes transitioning to the transitioned state, and when it fully reverts to the default or non-transitioned state. 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.
This code gets an element that has a transition defined and adds a listener to the
transitionend
event:
const transition = document.querySelector('.transition');
transition.addEventListener('transitionend', () => {
console.log('Transition ended');
});
一样,但使用
ontransitionend
:
const transition = document.querySelector('.transition');
transition.ontransitionend = () => {
console.log('Transition ended');
};
In the following example, we have a simple
<div>
element, styled with a transition that includes a delay:
<div class="transition">Hover over me</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: 1s;
}
.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';
});
transitionend
event is fired in both directions: when the box finishes turning and the opacity hits 0 or 1, depending on the direction.
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.
若
transitioncancel
event is fired, the
transitionend
event will not fire.
