The HTMLElement.oncut
property of the HTMLElement
interface is an event handler that processes cut
events.
The cut
event fires when the user attempts to cut text.
target.oncut = functionRef;
functionRef
is a function name or a function expression. The function receives a ClipboardEvent
object as its sole argument.
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.
<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>
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;
