Remarks For the onbeforeeditfocus event to fire, document elements must be in edit mode. One way to invoke edit mode is to set the designmode property to on. as of microsoft® internet explorer 5.5, web authors can also set the contenteditable attribute to true on the body element, and if necessary, to specific elements in the body, to invoke edit mode. the onbeforeeditfocus event differs from the onfocus event. the onbeforeeditfocus event fires before an object enters a ui-activated state, whereas the onfocus event fires when an object has focus.
Note This event also fires when an input or textarea object gets the focus in browse mode.
