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;
