544 Part III . Document Objects Reference Because the form.submit()method does not trigger the form s onSubmitevent handler, you must perform any presubmission processing and forms validation in the same script that ends with the form.submit()statement. You also do not want to interrupt the submission process after the script invokes the form.submit() method. Script statements inserted after one that invokes form.submit() espe cially those that navigate to other pages or attempt a second submission cause the first submission to cancel itself.

Immediately before a Reset button returns a form to its default settings, JavaScript sends a resetevent to the form. By including an onResetevent handler in the form definition, you can trap that event before the reset takes place. A friendly way of using this feature is to provide a safety net for a user who accidentally clicks the Reset button after filling out a form. The event handler can run a function that asks the user to confirm the action. The onReset event handler employs a technique that surfaced with Navigator 3: The event handler must evaluate to return truefor the event to continue to the browser. This may remind you of the way onMouseOver and onMouseOutevent handlers work for links and image areas. This requirement is far more useful here because your function can control whether the reset operation ultimately proceeds to conclusion.
