Remarks

Bubbles No

Cancels Yes

To invoke Submit a form using the INPUT TYPE=submit, INPUT TYPE=image, or BUTTON TYPE=submit object.

Default action Causes a form to be sent to whatever location is stipulated in the ACTION attribute of the form object.

You can override this event by returning false in the event handler. Use this capability to validate data on the client side to prevent invalid data from being submitted to the server. If the event handler is called by the onsubmit attribute of the form object, the code must explicitly request the return value using the return function, and the event handler must provide an explicit return value for each possible code path in the event handler function.

The submit method does not invoke the onsubmit event handler.
