SVGGraphicsElement: copy event

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

The event's default action is to copy the selection (if any) to the clipboard.

A handler for this event can modify the clipboard contents by calling setData(format, data) on the event's ClipboardEvent.clipboardData property, and cancelling the event's default action using event.preventDefault().

However, the handler cannot read the clipboard data.

It's possible to construct and dispatch a synthetic copy event, but this will not affect the system clipboard.

Syntax

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

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

oncopy = (event) => {};

Event type

A ClipboardEvent. Inherits from Event.
