How to prevent “Are you sure you want to navigate away from this page?” alert on form submission?

Question

I have a simple html form with few fields in it.

I wanted to make sure that user gets an alert message when he is trying to leave the page. So I added the script on

Try this: http://cfsilence.com/blog/client/index.cfm/2009/10/12/jQuery-Method-To-Prompt-A-User-To-Save-Changes-Before-Leaving-Page

I added another bit to the function:

 $('#submitButton').click(function () {
        isDirty = false;
});

Just so the form doesn't ask for validation when you want to submit it :)

I hope this helps

Note: You could also do something like $("input[type=submit]") if you don't like to depend on a common naming (else your submit button needs to be called submitButton)
