Pragmatic Ajax: A Web 2.0 Primer

Pragmatic Ajax: A Web 2.0 Primer

by JustinGehtland (Author), Ben Galbraith (Author), Dion Almaer (Author)


It's not just another book on Ajax. It's Pragmatic Ajax : a concise, complete look at a new way of envisioning and implementing browser-based applications. Ajax turns static web pages into interactive applications. Now you can deploy rich-client applications to clients without sacrificing the easy deployment of web applications. But to many folks, Ajax seems difficult. That's why we produced this book. As a Pragmatic guide, it strips away the mystery and shows you the easy way to make Ajax work for you. We cover the basics of DHTML, JavaScript, and the infamous XmlHttpRequest call. You'll see how to add Ajax to existing programs, and design new applications to exploit the power of Web 2.0. Learn the three layers of Ajax framework, and when (and how) to use each. See how to create rich clients, use visual effects, add client-side validation, and handle forms. Write applications that degrade gracefully if clients don't support JavaScript. And see how to integrate your Ajaxified clients into Java, .NET, and Ruby on Rails server frameworks. With Pragmatic Ajax , you'll: understand the breadth of the Ajax/Web 2.0 landscape, and go-indepth on how Ajax works; learn how JavaScript works with your server-side framework; see how to easily apply Ajax techniques to an existing application - and when not to; and know what's coming by looking at new features and frameworks currently in active development. Writing dynamic applications isn't that hard. Folks are awed by Google Maps, but it isn't rocket science (apart from the satellite pictures). As a special bonus, see how to implement your own Google Maps-like application using DHTML.
