onbeforeeditfocus event | beforeeditfocus event

Browser support:

Occurs before an input:file, input:password, input:text or textarea element or an element in an editable region becomes a UI-activated.

To specify an editable region, set the contentEditable property of an element to 'true' or the designMode property of the document to 'on'.

The UI-activated state differs from the activated state. For example, if you cancel the onbeforeeditfocus event on a input:text element, the element gets the focus but the caret will not be visible.

How to register:

In HTML:

In JavaScript:

object.onbeforeeditfocus = handler;

object.attachEvent ("onbeforeeditfocus", handler);
