code for calculate cgpa

Posted 01 April 2009 - 05:54 AM

<script language="Javascript" type="text/javascript">
function DisplayGred (GredPair) 
  var Gred = GredPair.split('|');
  var jam_kredit = document.getElementById('jam_kredit').value; // (user input pay amount student pay for course)
  document.getElementById('pointer').value = Gred[1]; //(display course fee when item is selected)

function CalculateCGPA ()
  var numberOfcourses = 10
  var totalpoints = 0
  var totalcredithours = 0
  for (var coursenumber = 1; coursenumber <= numberOfcourses;

  var Gred = document.getElementById('pointer').value;
  var jam_kredit = document.getElementById('jam_kredit').value; // (user input pay amount)
  var pointer = document.getElementById('pointer').value;
  var sumPointer = (pointer*1)*(jam_kredit*1);
  var gpa= sumPointer/jam_kredit;
  document.getElementById('sumPointer').value = sumPointer; //automatic display when calculate button is pressed
  document.getElementById('gpa').value = gpa; //automatic display when calculate button is pressed



This is the interface look alike, the code subject, subject name and credit hours are retrive from the database, so how to calculate it?
