oncopy
|
The event's default action is to copy the selection (if any) to the clipboard.
A handler for this event can
修改
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.
