<p>L'événement <strong><code>transitionend</code></strong> est déclenché lorsqu'une <a href="/en-US/docs/CSS/Using_CSS_transitions">transition CSS</a> est terminée. <span class="tlid-translation translation" lang="fr"><span title="">Dans le cas où une transition est supprimée avant la fin, par exemple si {{cssxref ("transition-property")}} est supprimé ou {{cssxref ("display")}} est défini sur</span></span> <code>none</code>, alors l'événement ne pourra pas être généré.</p>

<p>L'événement <code>transitionend</code> est déclenché dans les deux sens - à la fin de la transition vers l'état de transition et lorsqu'il revient complètement à l'état par défaut ou sans transition. S'il n'y a pas de délai ou de durée de transition, si les deux sont 0 ou qu'aucun n'est déclaré, il n'y a pas de transition et aucun des événements de transition n'est déclenché. Si l'événement <code>transitioncancel</code> est déclenché, l'événement <code>transitionend</code> ne se déclenchera pas.</p>

<h2 id="Examples">Examples</h2>
<p>This code gets an element that has a transition defined and adds a listener to the <code>transitionend</code> event:</p>
<pre class="brush: js notranslate">const transition = document.querySelector('.transition');
transition.addEventListener('transitionend', () => {
console.log('Transition ended');
});</pre>
<p>The same, but using the {{domxref("GlobalEventHandlers/ontransitionend", "ontransitionend")}}:</p>
<pre class="brush: js notranslate">const transition = document.querySelector('.transition');
transition.ontransitionend = () => {
console.log('Transition ended');
};</pre>
<h3 id="Live_example">Live example</h3>
<p>In the following example, we have a simple {{htmlelement("div")}} element, styled with a transition that includes a delay:</p>
<pre class="brush: html notranslate"><div class="transition">Hover over me</div>
<div class="message"></div></pre>
<pre class="brush: css notranslate">.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);
}</pre>
<p>To this, we'll add some JavaScript to indicate that the <code><a href="/en-US/docs/Web/API/HTMLElement/transitionstart_event">transitionstart</a></code>, <code><a href="/en-US/docs/Web/API/HTMLElement/transitionrun_event">transitionrun</a></code>, <code><a href="/en-US/docs/Web/API/Window/transitioncancel_event">transitioncancel</a></code> and <code>transitionend</code> 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.</p>
<pre class="brush: js notranslate">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';
});
</pre>
<p>{{ EmbedLiveSample('Live_example', '100%', '150px') }}</p>
<p>The <code>transitionend</code> event is fired in both directions: when the box finishes turning and the opacity hits 0 or 1, depending on the direction.</p>
<p>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.</p>
<p>If the <code>transitioncancel</code> event is fired, the <code>transitionend</code> event will not fire.</p>
