The practicing programmer's DEITEL(R) guide to AJAX, Rich Internet Applications, and web-application development This book applies the Deitel signature live-code approach to teaching Web 2.0 application development. The book presents concepts in the context of more than 180 fully tested programs (18,000+ lines of code), complete with syntax shading, detailed descriptions, and sample outputs. It features hundreds of tips that will help you build robust applications. Start with a concise introduction to XHTML, CSS, and JavaScript before rapidly moving on to more advanced client-side development with DOM, XML, AJAX, JSON, and other RIA technologies. Then proceed to server-side development with web servers, databases, PHP, Ruby on Rails, ASP.NET, JavaServer Faces, and web services. When you're finished, you'll have everything you need to build Web 2.0 applications. The DEITEL Developer Series is designed for practicing programmers. The series presents focused treatments of emerging technologies, including .NET, JavaTM, web services, Internet and web development, and more.

" --Paul Vencill, MITRE, Inc. "Cements the browser as a first-class development platform." --Johnvey Hwang, Splunk, Inc. "Congratulations on this excellent work. The [Dive Into Web 2.0] chapter is simply astonishing! It's one of the better--if not the best--references on Web 2.0." --Jose Antonio Gonzalez Seco, Parlamento de Andalucia "The CSS chapter is compact, concise, and full of useful info!" --Billy B. L. Lim, Illinois State University "One of the best introductions to JavaScript." --Raymond Wisman, Indiana University Southeast "A good introduction to the DOM; doesn't trip over cross-browser incompatibilities." --Eric Lawrence, Microsoft "Exceptionally clear Ajax tutorial; best I've reviewed! Great solutions for the very cool type-ahead and edit-in-place AJAX features. 'Libraries to Help Eliminate Cross-Browser Compatibility Issues' is fantastic. This book and your web sites will be often-visited resources (if not best practices in themselves)." --John Peterson, Insync and V.I.O. Inc. "Great chapter [on building Flash games]." --Jennifer Powers, University of Albany "A solid introduction to Adobe Flex with some very cool applications." --Matt Chotin, Adobe "A solid introduction to the capabilities and flexibilities of PHP. Inspired me to tighten up my own code! Easy to follow JSF development with database, Virtual Forms, and Google Maps." --John Peterson, Insync and V.I.O. Inc. "Excellent coverage of developing ASP.NET applications, with plenty of sample code." --Peter Bromberg, VOIP, Inc. "The web services chapter concludes a comprehensive education on Web 2.0. The examples go a long way to support the Web 2.0 mission of this book." --George Semeczko, Independent Consultant
