I gave a talk, recently, at @Media Ajax on jQuery (and a similar one at the Ajax Experience in Boston). I covered a broad amount of information (all the way from the absolute basics up to building and using plugins).
Here are the files mentioned in the talk:
- Accordion Menu (Apple.com) (Completed)
- Ajax Todo List (Completed)
- Ajax Social Networking Site (Completed)
I plan on turning the Ajax Social Networking Site demo into a screencast at some point, as some tend to find it rather compelling and useful.
Please let me know if you have any questions concerning the talk.
