I've been delighted with Eclipse PDT's context-sensitive lookup capabilities for PHP. I'm hoping for the same functionality for a Javascript-heavy project I'm working on but I've been unable to get Eclipse to do it for me.
I created a new Project and imported my existing Javascript and PHP code but when I try to use F3 within a Javascript file, it will look up vars locally defined but does not offer any code hinting or visibility to functions or classes defined in other Javascript files.
Can anyone recommend a means by which I can set up a true context-sensitive Javascript editor?
