If you're a web developer with previous jаvascript and DOM scripting experience, Accelerated DOM Scripting with Ajax, APIs, and Libraries is perfect for you to take your knowledge to the next level.
This book is about jаvascript and using the document object model—the conduit to the HTML document. This book is not about learning how to program jаvascript from scratch. It starts with the assumption that you have done some jаvascript development before and understand the jаvascript syntax. This book builds on 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 jаvascript 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.
jаvascript 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.
By reading this book, you should have a greater understanding of how jаvascript 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 jаvascript 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 jаvascript libraries, and know how best to apply these libraries to your projects.
