HTMLDialogElement: cancel event
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2022.
The cancel
event fires on a <dialog>
element when the user instructs the browser that they wish to dismiss the current open dialog. The browser fires this event when the user presses the Esc key.
This event is cancelable but can not bubble.
When a <dialog>
is dismissed with the Esc key, both the cancel
and close
events are fired.
Syntax
Use the event name in methods like addEventListener()
, or set an event handler property.
js
addEventListener("cancel", (event) => {});
oncancel = (event) => {};
Event type
