The book is a detailed reference guide, and an invaluable resource for answers to all your queries about jQuery. It is intended to be a quick reference to help at times when you need to quickly confirm a feature of the library. This book is for you if you are a web developer who wants a broad, organized view of all that jQuery library has to offer or a quick reference on their desk to refer to for particular details. Basic knowledge of HTML and CSS is required. You should be comfortable with the syntax of JavaScript,but no knowledge of jQuery is assumed. This is a reference guide, not an introductory title and if you are looking to get started with jQuery 1.3 (or JavaScript libraries in general) then you are looking for the companion title Learning jQuery 1.3.
