This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.


The oncut property returns the onCut event handler code on the current element.


element.oncut = functionRef;

where functionRef is a function - often a name of a function declared elsewhere or a function expression. See Core JavaScript 1.5 Reference:Functions for details.


<title>oncut event example</title>

function log(txt) {
    document.getElementById("log").appendChild(document.createTextNode(txt + "\n"));

<h3>Play with this editor!</h3>
<textarea rows="3" cols="80" oncopy="log('Copied!');" oncut="log('Cut blocked!'); return false;">
  Try copying and cutting the text in this area!
<textarea rows="15" cols="80" id="log" readonly="true"></textarea>

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.


This event is sent when the user attempts to cut text.

Since Firefox 13, the preference dom.event.clipboardevents.enabled controls this feature. It defaults to true but can be disabled.
