At the present time, when a button which is an ajax submit is clicked,
control is transferred to the JavaScript that checks for correctly
populated required fields. If there is a required field that is not
correctly populated, an alert box is displayed. When the alert box is
closed, the ajax request proceeds with incorrect data. I want the ajax
http request aborted if the JavaScript finds a problem with the data.
