What is a good place to start playing with jQuery, besides the jQuery website. I'm having trouble with the way the site is set up - I dislike it.
this is a very good book jQuery in Action After reading the book, read jQuery source code.
One of the best ways to learn it is go through the tutorials and actually write the code from scratch, don't just read them. Also look at some problems you want to solve using jQuery and try a few different approaches to solving them to find all the different ways it allows you to work. jQuery is very rich and there's more than one way to skin your site...I mean cat.
Official document is not always that easy to grasp. I found this to be extremely useful resource for learning jquery:
Yet another site, dedicated to jQuery, I found very useful for me - visualjquery.com. One of the creators of this site is also author of the great book "jQuery in Action"(Yehuda Katz).
As for me, resource is well orginized and extremely handy.
