There's no cross-browser JS debugger that I know of (because most browsers use different JS engines).
For firefox, I'd definitely recommend firebug (http://www.getfirebug.com)
For IE, the best I've found is Microsoft Script Debugger (http://www.microsoft.com/downloads/details.aspx?familyid=2f465be0-94fd-4569-b3c4... |
1. You can use Visual Studio and enable debugging in browser
2. You can install FireBug plugin for Firefox, it's really good!
3. You can try to install IE8 beta 2 and use it in compatibility mode with built-in debugger.
Also in any line of your JS code you can write

Best Practice for Creating Data Tables Without Controls in ASP.net |

So, I am kinda new to ASP.net development still, and I already don't like the stock ASP.net controls for displaying my database query results in table format. (I.e. I would much rather handle the HTML myself and so would the designer!)

If you only need read-only access to the mirrored repository, you can use [svnsync](http://svn.collab.net/repos/svn/trunk/notes/svnsync.txt) which was added in SVN 1.4 for mirroring. We use a secondary repository on our build server to run CruiseControl.Net against. But the mirrored repository is read-only. |
I think Patrick nailed this one -- my only suggestion is to remember that named regex groups exist, too, so you don't *have* to use array index numbers.
