onbeforecut event | beforecut event

Browser support:

Occurs before the selection is cut from the document and provides a possibility to enable the Cut menu item.

The onbeforecut event is useful if you want to enable the Cut menu item for texts that are not in an editable element (textarea, input:text, input:file and input:password) and not in an editable region (see the contentEditable and designMode properties). To enable the Cut menu item for an element, return false from an event handler for the onbeforecut event on it.

In Internet Explorer, if the user selects the Cut menu item for a non-editable content, the oncut event is fired and the selected content is cut.
In Google Chrome and Safari, the oncut event is fired but the selected content is left untouched.

If you want to implement the functionality of the Cut operation in Google Chrome and Safari, see the page for the clipboardData object. It contains a cross-browser example that shows how to access the clipboard. To remove the contents of the selection from the document, use the deleteFromDocument method.

In Internet Explorer, the onbeforecut event occurs on the deepest element in the DOM hierarchy that contains the entire selection.
In Google Chrome and Safari, the onbeforecut event occurs on the deepest element in the DOM hierarchy that contains the start point of the selection.
