               if(submitflag=='0' && page==true)
                    var confm=confirm("Page status is changed,do you want create new user");
                    if(confm=='true')
                         alert("Click on save to save ur changes.");
                         document.form[0].focus();
                         return false;
               return false;
          function updatepage()
               page=true;
          function changedvalues()
               var totalele=document.emailaddressForm.elements.length;
