Book Description:
Professional Ajax 2nd Edition provides a developer-level tutorial of Ajax techniques, patterns, and use cases. The book begins by exploring the roots of Ajax, covering how the evolution of the web and new technologies directly led to the development of Ajax techniques. A detailed discussion of how frames, JavaScript, cookies, XML, and XMLHttp requests (XHR) related to Ajax is included. After this introduction, the book moves on to cover the implementation of specific Ajax techniques. Request brokers such as hidden frames, dynamic iframes, and XHR are compared and contrasted, explaining when one method should be used over another. To make this discussion clearer, a brief overview of HTTP requests and responses is included.
Once a basic understanding of the various request types is discussed, the book moves on to provide in-depth examples of how and when to use Ajax in a web site or web application. Different data transmission formats, including plain text, HTML, XML, and JSON are discussed for their advantages and disadvantages. Also included is a discussion on web services and how they may be used to perform Ajax techniques. Next, more complex topics are covered. A chapter introducing a request management framework explores how to manage all of the requests inside of an Ajax application. Ajax debugging techniques are also discussed.
The last part of the book walks through the creation of two full-fledged Ajax web applications. The first, FooReader.NET, is an Ajax-powered RSS reader. The second, called AjaxMail, is an Ajax-enabled email system. Both of these applications incorporate many of the techniques discussed throughout the book.
Professional Ajax 2nd edition is written for Web application developers looking to enhance the usability of their web sites and web applications and intermediate JavaScript developers looking to further understand the language. Readers should have familiarity with XML, XSLT, Web Services, PHP or C#, HTML, CSS. This book is not aimed at beginners without a basic understanding of the aforementioned technologies. Also, a good understanding of JavaScript is vitally important to understanding this book. Those readers without such knowledge should instead refer to books such as Beginning JavaScript, Second Edition (Wrox, 2004, ISBN: 978-0-7645-5587-9) and Professional JavaScript for Web Developers (Wrox, 2005, ISBN: 978-0-7645-7908-0).
Professional Ajax 2nd edition adds nearly 200 pages of new and expanded coverage compared to the first edition. Some of the new topics covered here include:
Ajax Libraries including the Yahoo! Connection Manager, Prototype, and jQuery
Request Management with Priority Queues and the RequestManager Object
Comet push-based web systems and HTTP streaming
Maps and Mashups with Geocoding, Google Maps API and Yahoo! Maps API
Ajax Debugging with FireBug and Microsoft Fiddler
ASP.NET AJAX Extensions (formerly code-named "Atlas")
And of course the Second Edition retains and updates the core first edition content including:
the range of request brokers (including the hidden frame technique, iframes, and XMLHttp) and explains when one should be used over another
different Ajax techniques and patterns for executing client-server communication
Ajax patterns including predictive fetch, page preloading, submission throttling, incremental field and form validation, periodic refresh, multi-stage download and more
Syndication with RSS, Atom, and XParser
JSON and creating an autosuggest textbox example
web site widgets for a news ticker, weather information, web search, and site search
Ajax Frameworks JSpan, DWR, and Ajax.NET Professional
A Web-based RSS/Atom aggregator case study
An AjaxMail case study
Sick of creating web sites that reload every time a user moves the mouse? Tired of servers that wait around to respond to users' requests for movie tickets? It sounds like you need a little (or maybe a lot of) Ajax in your life. Asynchronous programming lets you turn your own web sites into smooth, slick, responsive applications that make your users feel like they're back on the information superhighway, not stuck on a dial-up backroad.
But who wants to take on next-generation web programming with the last generation's instruction book? You need a learning experience that's as compelling and cutting-edge as the sites you want to design. That's where we come in. With Head Rush Ajax, in no time you'll be writing JavaScript code that fires off asynchronous requests to web servers...and having fun doing it.

Ajax is no longer an experimental approach to website development, but the key to building browser-based applications that form the cornerstone of Web 2.0. Head First Ajax gives you an up-to-date perspective that lets you see exactly what you can do -- and has been done -- with Ajax. With it, you get a highly practical, in-depth, and mature view of what is now a mature development approach.
Using the unique and highly effective visual format that has turned Head First titles into runaway bestsellers, this book offers a big picture overview to introduce Ajax, and then explores the use of individual Ajax components -- including the JavaScript event model, DOM, XML, JSON, and more -- as it progresses. You'll find plenty of sample applications that illustrate the concepts, along with exercises, quizzes, and other interactive features to help you retain what you've learned.
Head First Ajax covers:
The JavaScript event model
Making Ajax requests with XMLHTTPREQUEST objects
The asynchronous application model
The Document Object Model (DOM)
Manipulating the DOM in JavaScript
Controlling the browser with the Browser Object Model
XHTML Forms
POST Requests
XML Syntax and the XML DOM tree
XML Requests&Responses
JSON -- an alternative to XML
Ajax architecture & patterns
The Prototype Library
The book also discusses the server-side implications of building Ajax applications, and uses a "black box" approach to server-side components.
Head First Ajax is the ideal guide for experienced web developers comfortable with scripting -- particularly those who have completed the exercises in Head First JavaScript -- and for experienced programmers in Java, PHP, and C# who want to learn client-side programming.
