[Javascript] RE: Undefined is Undefined in IE 5

[Dan Costea]

undefined - is a reserved key word, so you should use it without ". If you say: "undefined" - this is just a string. I used undefined in IE5 and IE6 and it worked fine... But in your case, I think is better to use:

var AverageStudentsObj = document.getElementById("AverageStudents"); 
  if (AverageStudentsObj)
    alert (AverageStudentsObj);
  else
    alert ('object not found');

  HI Everyone, 

  The following code works in IE 6 but falls over with the error "Undefined is Undefined" 
  in IE 5.  Does anyone know what the actual problem is and is there  a workaround? 

  var AverageStudentsObj = document.getElementById("AverageStudents"); 
    if ( AverageStudentsObj != undefined ) 

  thanks
