Answer 1

In $(document).ready(), your syntax is wrong,

you forgot to write function() in .ready(function (){ .... });

$(document).ready(function() {
   if(load_flag == 2) {
     $("#validate").css({'display':'block'});
     $("#start").css({'display':'none'});
     $("#confirm").css({'display':'none'});
     window.onbeforeunload = confirmExit ;
   }
});
