transitionend

The 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 is set to "none", then the event will not be generated.

Example

This example sets up an event handler to detect the transitionend event, in order to change the text displayed inside the element once the transition is complete.

let element = document.getElementById("slidingMenu");
element.addEventListener("transitionend", function(event) {
  element.innerHTML = "Done!";
}, false);
