Validator causes improper behavior for double click check

Question

I have following script to prevent a button from submitting twice by double clicking. It works fine.

But the scenario gets clumsy when I added a R

Answer 1

I think somthin like this:

 $('.myButton').click(function (e) {
        if(Page_IsValid){
        if (isActionInProgress == 'No') {
            isActionInProgress = 'Yes';
        }
        else {
            e.preventDefault();
            //alert('STOP');
        }
      }

    });
