JavaScript applications. This book will guide you past the pitfalls

associated with AJAX, events, effects, and advanced JavaScript language

features, as well as provide you with a reference to the jQuery library

to return to again and again. This book begins with a tutorial to

jQuery, followed by an examination of common, real-world client-side

problems, and solutions for each of them.A detailed reference rounds off

jQuery questions. Who this book is written for This book is for web

designers who want to create interactive elements for their designs, and

jQuery is assumed, nor is experience with any other JavaScript libraries

required.
