I am using following JavaScript code to warn a user if he tries to redirect to another page without submitting the form.

window.onbeforeunload = function() {
   return 'Are you sure that you want to leave this page?';
};

This is working fine.But my problem is when user trying to submit the form using submit button confirm box will be appear. I don't want to ask the confirm if user submitting the form,otherwise I want to ask confirm. How is it possible?

javascript jquery confirm
