Multiple submit Button click problem?

Question

Answer 1

Do not disable the button, just prevent the second submit.

this little script does the job but it assumes there is a postback at a certain moment.

var formhandler = function() {
   var submit, isSubmit = false;
   submit = function(){
                // flop and return false once by the use of operator order.
    return isSubmit != (isSubmit = true);
    };
    return {
       submit: submit
    };
}(); // <-- use direct invcation to keep the internal variables "static"

attach it by :

   document.forms[0].onsubmit = formhandler.submit;    

or

   OnClientClick = "formhandler.submit()";
