Check the Browser compatibility table carefully before using this in production.
The HTMLElement.onpaste
property of the
HTMLElement
interface is an EventHandler
that processes
paste
events.
The paste
event fires when the user attempts to paste text.
Note that there is currently no DOM-only way to obtain the text being pasted; you'll
have to use an nsIClipboard
to get that information.
Syntax
target.onpaste = functionRef;
Value
functionRef
is a function name or a function
expression. The function receives a ClipboardEvent
object as its
sole argument.
Example
This example logs every copy and paste attempt to the <textarea>
.
HTML
<h3>Play with this text area:</h3>
<textarea id="editor" rows="3">Try copying and pasting text into this field!</textarea>
<h3>Log:</h3>
<p id="log"></p>
JavaScript
function logCopy(event) {
log.innerText = 'Copied!\n' + log.innerText;
}
function logPaste(event) {
log.innerText = 'Pasted!\n' + log.innerText;
}
const editor = document.getElementById('editor');
const log = document.getElementById('log');
editor.oncopy = logCopy;
editor.onpaste = logPaste;

but can be disabled.
