onBlur is usually used for field validation, or updating dependent fields. Imagine a form with three text fields and a total. While you are editing one of the fields, you don't want the total to change, but you don't want to have to press a button to update it either. So set the onBlur() handler of each of the input fields to a method which updates the total. Now whenever you move out of a field, th etotal will be updated.
Hi, The onBlur event is executed when the object loses its focus, ie., when the cursor is moved from the current object to any other object in the form. This is normally used for validation or object value updation. Bye, Prabhu.V.C ------------------
