Javascript code hinting, lookup via F3 [message #809304]

I've been delighted with 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?

Did you make it a JavaScript project from the project's Configure menu?

I did make it a Javascript project. As it turns out, the issue was that Eclipse had not yet scanned all the Javascript files.

At the moment, I'm finding myself wanting Eclipse to provide code hinting and autocompletion. Does it do this for Javascript? I got it autocomplete/hint working in Eclipse for PHP by adding Javadoc comments. Wondering if there's any sort of documentation or best practices for Javascript dev in Eclipse?

Now Eclipse will not look up class definitions when I hit F3. It was doing it fine for awhile then something changed. I was wondering if I was out of memory or something but that does not seem to be the case. I think Eclipse might have some kind of bug.

OK I'm getting infuriated by the inconsistent behavior of Eclipse here. One day it works and F3 is my reliable buddy and I can look up almost anything. Today, it's "Current text selection does not resolve to a Javascript element." WTF??!!1

Is there some way to reset the code hinting or force a rescan on a given Javascript project? I need this functionality NOW.
