[Javascript] How implement drop-down list box values in asp with javascript-reg

[shawn.milo at gmail.com (Shawn Milo)]

The way I do this is to create Javascript arrays with ASP during the
page load. Then, in the 'onclick' event of the first two drop-down
boxes, I have code to fill or clear the boxes.

I will e-mail a more complete example once I get to work, where most
of my code is, but here's something to get you started. I did this off
of the top of my head, so it may not my 100% accurate as far as
syntax.

Example:

<script type="text/javascript">
   //note -- this Javascript is written by the ASP

   var aColleges = new Array();
   var aDepts = new Array();
   var aEvents = new Array();

   aColleges[aColleges.length] = new Array('1', 'School One');
   aColleges[aColleges.length] = new Array('2', 'University X');
   aColleges[aColleges.length] = new Array('3', 'State College');
   aColleges[aColleges.length] = new Array('4', 'Bigtown College');

   //Note that here, the '1' refers to 'School One, and the
   // 14 refers to the department code
   aDepts[aDepts.length] = new Array('1', '14','Science');
   aDepts[aDepts.length] = new Array('1', '15','Art');
   aDepts[aDepts.length] = new Array('1', '16','History');
   aDepts[aDepts.length] = new Array('2', '17','Computer Science');
   aDepts[aDepts.length] = new Array('2', '19','Biology');
   aDepts[aDepts.length] = new Array('2', '25','Philosophy');
   aDepts[aDepts.length] = new Array('2', '33','Engineering');

   aEvents[aEvents.length] = new Array('17', 'Linux Install-Fest');
   aEvents[aEvents.length] = new Array('15', 'Student Art Exhibit');
   aEvents[aEvents.length] = new Array('25', 'Taoism Lecture);


</script>
