determine number of columns in table data

[cylly]

How can I find out the number of columns in my table? The information is loaded dynamically. The number of columns will vary depending on what information was selected from a previous page.

Any help would be greatly appreciated.

Hi,

This might work for you. First, if it doesn't already have one, give your table a header row. If you don't want it to show up, use "display:none" to hide it from view. Then, for every element in your header row, give it an ID (in this example, "me&quot. Then the following JavaScript code will count the number of cells with the ID "me":

var x = document.getElementsByTagName("TD");
var i=0;
var cols = 0;
while(i<x.length) {
  if (x.item(i).id == 'me') { cols++; }
  i++;
}

I think you can do something simpler with getElementByID (check out

http://developer.apple.com/internet/javascript/dom2ii.html),

but I couldn't get that working in the last fifteen minutes of work.

Hope that helps,

Misty
