By the time I was finished reading the book, I knew enough about jQuery to tackle any challenges related to client-side scripting that I needed to tackle for my project.
The book does a solid review of the core jQuery library covering anything I felt I needed to know about jQuery to be autonomous with the library and then some.
Everything is explained clearly and in enough details to get a firm grasp about the nuances of the covered APIs.
All the API functions are detailed using a full function specification with complete coverage of the function behavior, parameters and return values.
Note: The second part of the book (about jQuery UI) was of lesser interest to me so I only skimed through it, but it looked good too. This review pertain to the first part of the book covering the jQuery core library however.
I am not entirely convinced the author is a competent programmer. The explanations of code seem clear when reading the book, but the downloaded tutorials do not seem to work. When trying to run the tutorials the page hangs up on jQuery methods, which is really shoddy for a book looking to teach that language.
I read this book cover to cover - it's more than a reference, it takes the reader through the intricacies of the jQuery (and jQuery UI) libraries. The narration regarding the examples is excellent.. some of the other books I glanced at before choosing this title were full of examples that were not actually explained very well. I'm not sure this book is for beginners, or for those looking for 'cookie cutter' scripts to drop into their pages, but more for those who really want to understand what's happening, of course leading to innovative new functionality.
I'll add that jQuery itself is more powerful than I had first thought - hats off to the creator of jQuery! Thank you for creating such a fantastic tool. And to the jQuery UI Team - fantastic work as well.
