I've just figured out how to enable jQuery code assist in Eclipse (Kepler), partly thanks to this post. So yeah I've got code assist on some of the API, but not on things like $.ajax(), or $.parseJSON(). Code assist for $('#id') does provide the expected functions like bind() and on(). $. just provide apply() and call(), which are only some of the JS function methods. It also seems to matter where in code I call on $, yielding different results in different places.
What could be the reason for this? I'd love to have code assist for the $ methods.
