Event handler parameters

Remarks

The onblur event fires on the original object before the onfocus or onclick event fires on the object that is receiving focus. Where applicable, the onblur event fires after the onchange event.

Use the focus events to determine when to prepare an object to receive or validate input from the user.

As of Microsoft Internet Explorer 5, you must set the tabIndex attribute of elements that expose the onblur event.

For Internet Explorer 5 and later, the onblur event is asynchronous.

Switches focus away from the object on which the event is fired.

To invoke this event, do one of the following:

  • Click the mouse on the document background or another control.
  • Use the keyboard to navigate from one object to the next.
  • Invoke the blur method when an object has focus.
  • Switch focus to a different application or open a second window.

The pEvtObj parameter is required for the following interfaces:
