HTMLElement.oncut

Experimental

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

The HTMLElement.oncut property of the HTMLElement interface is an EventHandler that processes cut events.

The cut event fires when the user attempts to cut text.

Syntax

target.oncut = functionRef;

Value

functionRef is a function name or a function expression. The function receives a ClipboardEvent object as its sole argument.

Example

This example allows text to be copied from the <textarea>, but doesn't allow text to be cut. It also logs each copy and cut attempt.

HTML

<h3>Play with this text area:</h3>
<textarea id="editor" rows="3">Try copying and cutting the text in this field!</textarea>

<h3>Log:</h3>
<p id="log"></p>

JavaScript

function logCopy(event) {
  log.innerText = 'Copied!\n' + log.innerText;
}

function preventCut(event) {
  event.preventDefault();
  log.innerText = 'Cut blocked!\n' + log.innerText;
}

const editor = document.getElementById('editor');
const log = document.getElementById('log');

editor.oncopy = logCopy;
editor.oncut = preventCut;
