HTMLElement.onpaste

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The HTMLElement.onpaste property of the HTMLElement interface is an event handler 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;
