Beginning JavaScript with DOM Scripting and Ajax, 2nd Edition: This book will teach you about JavaScript and how to use it in a practical manner. After you read it, you’ll be able to Understand JavaScript syntax and structures. • Create scripts that are easy to understand and maintain. • Write scripts that do not interfere with others. • Write scripts that make web sites easier to use without blocking out non-JavaScript users. • Write scripts that are independent of the browser or user agent trying to understand • them—which means that in some years they will still be usable and won’t rely on obsolete technology. Enhance a web site with JavaScript, and allow developers without any scripting knowledge to • change the look and feel. Enhance a web document with JavaScript, and allow HTML developers to use your • functionality by simply adding a CSS class to an element. Use progressive enhancement to make a web document nicer only when and if the user agent • allows for it. Use Ajax to bridge the gap between the back end and client side, thus creating sites that are • easier to maintain and appear much slicker to the user. Use JavaScript as part of a web methodology that enables you to maintain it independently • without interfering with the other development streams.
