HTMLDialogElement: cancel event

The cancel event fires on a <dialog> 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 does 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.

addEventListener("cancel", (event) => {});

oncancel = (event) => {};

Event type

A generic Event.
