Professional Ajax (Programmer to Programmer) (Taschenbuch)

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).

Connection Manager, Prototype, and jQuery; Request Management with Priority Queues and the RequestManager Object; and, Comet push-based web systems and HTTP streaming.It also covers: Maps and Mashups with Geocoding, Google Maps API and Yahoo! Maps API; and, Ajax Debugging with FireBug and Microsoft Fiddler ASP.NET AJAX Extensions (formerly code-named "Atlas").
