This is my .ctags file for editing JavaScript and Coffeescript. This, combined with Exuberant CTags (etags) will generate pretty good tags for use with auto-complete-mode and -. (find-tag) and other tag- queries from the command buffer in Emacs. You can find the latest auto-complete-mode at http://cx4a.org/software/auto-complete/

I highly recommend using these to edit JS/CS, as they are the closest to in-browser debug console autocompletion that you'll find anywhere. Much thanks to @mads379 for his gist on coffeescript ctags regexes (https://gist.github.com/907245) and George V. Reilly for his post on JS ctags (http://weblogs.asp.net/george_v_reilly/archive/2009/03/24/exuberant-ctags-and-javascript.aspx). As you can see, I merely combined the two and added the class definition line to the coffeescript stuff. Fork away!
