SVGGraphicsElement: copy 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 2017.
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.
addEventListener("copy", (event) => {});
oncopy = (event) => {};
Event type
A ClipboardEvent
. Inherits from Event
.
