As I say, prerequisites are: general programming skills, HTML, CSS and JavaScript, general understanding of Web applications. If all of the above is good, the following will be more than enough:
http://en.wikipedia.org/wiki/JQuery[
^],
http://docs.jquery.com/Tutorials[
^],
http://docs.jquery.com/Main_Page[
^] (documentation and reference is on this page).
For alternative tutorial, you can use this:
http://www.w3schools.com/jquery/[
^].
Everything else you can just find on the Web as you do your development and need more expressive power.
