Need to find actual location of line/char in Internet Explorer Script errors?

Question

I\'m receiving a script error in IE:

Line: 59 Char: 71 Error: Expected identifier, string, or number Code: 0

Line 59, character 71 don\'t seem to actually corres

I've found IE Line # / Char #'s to be useless or more hassle then it's worth.

If you're including multiple javascript files and all it gives you is a line # and char # it's alot of work to concatenate all the scripts together to figure it out where the error is.

If I can find the error in firefox using firebug then that's the easiest way. If it's an IE only problem what I do is enable script debugging in Internet Options,

1. Go to Tools->Internet Options…->Advanced->Disable Script Debugging (Internet Explorer)

2. Go to Tools->Internet Options…->Advanced->Disable Script Debugging (Other)

   then attach Visual Studio Debugger when an error occurs.

If you're using IE 8, install the developer toolbar because it has a built in debugger.

If you are really keen on not using a debugger and just viewing the source and getting the line # you can try View -> Original Source in the IE Developper toolbar.

In your case you gotta watch out for trailing comma's in object literals

var obj = { 
a: 1, 
b: 2,
}

Or naming a variable with a reserved keyword like "class", that has burned me many times. Here is a list of reserved keywords
