Is there a way to troubleshoot my Rails javascript application.js in IE 8?

Question

I have an application that works famously in Firefox, Safari, and Opera, but fails in IE 8. It give a really stupid error message:

Message: Object doesn't support this property or method
Line: 350
Char: 3
Code: 0
URI: http://evokat.localhost.com/javascripts/application.js?1343661671

All that does is point to the first letter of this line (which is indented 2 spaces):

partslist = $("#partslist").dataTable({
              "bPaginate": false,
              "bLengthChange": false,
              "bFilter": false,
              "bSort": false,
              "bInfo": false });

Naturally, my 2 largest customers use Internet Explorer 8. That error message tells me absolutely nothing, and I am unable to locate a Firebug-like debugging environment for IE. What is the next step I should take please?
