Re: [wtp-dev] jquery javascript code completion is not supported.

Jim,
The first hurdle would be bug 298577*, since using undefined in that 
manner isn't currently supported.  There are also parts of jQuery itself 
that confuse our parser, mostly having to do with regular expressions. 
After that, it falls down to the same 3 areas as does supporting any 
library: 
1) Using the org.eclipse.wst.jsdt.core.inferrenceSupport extension point 
to add an engine to help infer Types and type information; possibly not 
useful in this case because jQuery doesn't document types in its source. 
The main use case for this is when a library documents its type 
information in a format other than JSDoc.
2) Using the /org.eclipse.wst.jsdt.ui.documentationProvider extension 
point to help find and render documentation for the JavaScript types, 
methods, and fields; probably not needed since jQuery doesn't have its own 
custom documentation format.  Again, JSDoc is supported, and to a certain 
extent, simple line comments in the style jQuery uses.
3) Adding the necessary support for an IncludePath container, which is 
only useful if you're interested in providing jQuery for JavaScript 
development from within Eclipse plug-ins--and anyone could just as easily 
download it themselves and add it to their JS project.

While I don't think there's much preventing it from working, the parser 
changes themselves will have to wait for WTP 3.3.
