Accelerated DOM Scripting with Ajax, APIs, and Libraries
From the Back Cover
In this book, you'll learn:
*Where CSS, HTML, and the DOM fit into modern scripting, and how to use them together effectively*OOP techniques for more efficient JavaScript coding
*How to use JavaScript libraries such as Prototype in your work
*How to build effective form validation into your applications using Ajax
*How to create mashups using APIs
*How to build dynamic user interfaces
JavaScript has seen a resurgence in popularity over the past few years, and with it has come an exploration of the power of the language as well as what it can do within the browser. This book will explain techniques new and old—such as closures, encapsulation, and inheritance—that many are using and how you can best apply them to your own projects.
This book is about JavaScript and using the document object model—the conduit to the HTML document. This book is not about learning how to program JavaScript from scratch. It starts with the assumption that you have done some JavaScript development before and understand the JavaScript syntax. This book builds on top of that knowledge to give you a deeper understanding of DOM Scripting and how to apply that to your projects. It uses this new understanding to describe what JavaScript libraries are and show you how they can be applied to your project. The book will also explain Ajax and how best to plan and apply it to your projects. It explains how to build simple animation objects for adding movement to elements on the page. There are straightforward examples that demonstrate the techniques used throughout the book.
By reading this book, you should have a greater understanding of how
JavaScript works and be able to use advanced concepts such as closures
and event delegation to build more flexible applications for the Web.
You'll walk away with a greater appreciation for JavaScript libraries
and how they can simplify and speed up your development. You'll also be
able to implement Ajax effectively into your site, create special
effects, use JavaScript libraries, and know how best to apply these
libraries to your projects.

Who is this book for?
This book is intended for beginners to intermediate web developers who already have a previous JavaScript and DOM scripting experience.Conclusion
The
book is a lightweight 250 pages and is written in a pretty enjoyable
and understandable way to read. The content is well-structured, set out
in a successive, grading in the topic manner.
The book starts reviewing the state of JavaScript within the industry. Then it goes on focusing on methodology and technologies for rapid development with JavaScript, including OOP and events, but also Ajax frameworks and JavaScript libraries. Three complete projects for you to learn from: form validation, mashups, and UI design complete its content. All the example code in the book is built around the modern scripting principles of progressive enhancement and unobtrusive scripting, with usability and accessibility always in mind.
Overall, the book takes a positive and pragmatic view at the use of DOM scripting. It embraces and delves into the most common topics such as working with the DOM, Ajax, and visual effects.
We recommend this book for beginning or intermediate users who want to learn all about the DOM, AJAX and related technologies.
