I often like to have all my resources as pdf files but in some cases a reference book can come in handy. Easy to pick up without the need for extra screens (They are full with applications anyway)
The book has the basics of setting up the JQuery framework and start using it to creating Dom nodes, setting css styles,classes. Adding animations to elements and also a little section on how to use JQuery mobile.
And the great part is that the book has quick explanations and then a code snippet that you can test, So you will get a great reference guide and also learn to use jQuery more when you develop new applications.
The books developer audience is developers that isn’t experienced JQuery Developers but what to get started or just started to use JQuery.
