The copy event fires when the user initiates a copy action through the browser's user interface.

The original target for this event is the Element that was the intended target of the copy action. You can listen for this event on the Document interface to handle it in the capture or bubbling phases. For full details on this event please see the page on the Element: copy event.

Use the event name in methods like addEventListener(), or set an event handler property.

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

oncopy = (event) => {};

A ClipboardEvent. Inherits from Event.

To be informed when a user copies data from the webpage to their clipboard, you can add a handler to your Document instance using addEventListener(), like this:

document.addEventListener("copy", (event) => {
  /* the session has shut down */
});

Alternatively, you can use the Document.oncopy event handler property to establish a handler for the copy event:

document.oncopy = (event) => {
  /* the session has shut down */
};
