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.

Example

This example shows how to display the name of the object that has lost focus, that is, the object that fires the onblur event.
