     try it, but it only worked in IE:

    <html>
    <head>
    <body  onBeforeUnLoad="clean_exit(this)"  >
    something else........

    <script language="JavaScript">  
    var changes=false;
    var problems=false;
     
    function clean_exit( src ){
          verify();  
          if (problems){
                alert ("problems: " + problems);
                // the verify routine reports problems, don't allow an exit or reloading of the page
          }else{
                // no problems, so continue
                if(changes){        
                      if (!confirm("You have made changes.  Click OK to save, or cancel to continue without saving")){
                            return false;  
                      }else{
                            //do something  
                            return true;
                      }  // end of confirm
                } // end of changes
          }// end of verify
    }

    function changed(){    
          changes=true;
    }
     
    function verify(){    
          var problems=false;
          with (Entry) {
                if (LastName.value == "") {  
                      problems=true;
                      return false;
                }
          }
          changes=false;
          return true;
    }  
    </script>
    </body>
    </html>
