Written for experienced web developers, Professional Ajax shows how to combine tried-and-true CSS, XML, and JavaScript technologies into Ajax. This provides web developers with the ability to create more sophisticated and responsive user interfaces and break free from the “click-and-wait” standard that has dominated the web since its introduction. Professional Ajax discusses the range of request brokers (including the hidden frame technique, iframes, and XMLHttp) and explains when one should be used over another. You will also learn different Ajax techniques and patterns for executing client-server communication on your web site and in web applications. By the end of the book, you will have gained the practical knowledge necessary to implement your own Ajax solutions. In addition to a full chapter case study showing how to combine the book’s Ajax techniques into an AjaxMail application, Professional Ajax uses many other examples to build hands-on Ajax experience. Professional Ajax readers should be familiar with CSS, XML, JavaScript, and HTML so you can jump right in with the book and begin learning Ajax patterns, XPath and XSLT support in browsers, syndication, web services, JSON, and the Ajax Frameworks, JPSpan, DWR, and Ajax.NET

This practical guide shows you how to make your Java web applications more responsive and dynamic by incorporating new Ajaxian features, including suggestion lists, drag-and-drop, and more. Java developers can choose between many different ways of incorporating Ajax, from building JavaScript into your applications “by hand” to using the new Google Web Toolkit (GWT). Ajax on Java starts with an introduction to Ajax, showing you how to write some basic applications that use client-side JavaScript to request information from a Java servlet and display it without doing a full page reload. It also presents several strategies for communicating between the client and the server, including sending raw data, and using XML or JSON (JavaScript Object Notation) for sending more complex collections of data.

Ajax and REST Recipes: A Problem-Solution Approach will serve all of your Ajax needs, by providing adaptable solutions for common tasks you’ll want to implement on web sites using the next generation of Ajax and REST techniques. As a JavaScript developer, your time is precious, so you’ll want to solve problems that present themselves in your work as quickly as possible. You can pick up the code provided in this book, adapt it, or plug it straight into your own applications. The book mainly focuses on illustrating and explaining how to build applications that use JavaScript, Ajax, and REST Web Services, along with some user interface issues. Specifically, the following topics are covered: implementing JavaScript unit tests; explaining the intent of Dynamic Languages, Web Services and SOA; defining and implementing contracts using REST; understanding why JavaScript Functions have state; implementing JavaScript “Generics”, which are a mixture between real Generics and a replacement algorithm; using code blocks; using functions to make decisions; understanding the difference of JavaScript code that behaves like a value type or a reference type; implementing proxies, delegates, mixins, and overloaded functions; implementing a complete Ajax and Web Service architecture; defining a Web Service using REST; handling large or slow or real-time data sets; implementing shopping cart type architectures; and solving the back button problem using Ajax.

Ajax, or Asynchronous JavaScript and XML, exploded onto the scene in the spring of 2005 and remains the hottest story among web developers. With its rich combination of technologies, Ajax provides a strong foundation for creating interactive web applications with XML or JSON-based web services by using JavaScript in the browser to process the web server response. Ajax Design Patterns shows you best practices that can dramatically improve your web development projects. It investigates how others have successfully dealt with conflicting design principles in the past and then relays that information directly to you. Ajax Design Patterns will also get you up to speed with core Ajax technologies, such as XMLHttpRequest, the DOM, and JSON. Technical discussions are followed by code examples so you can see for yourself just what is-and isn’t-possible with Ajax. This handy reference will help you to produce high-quality Ajax architectures, streamline web application performance, and improve the user experience.

Ajax, the popular term for Asynchronous JavaScript and XML, is one of the most important combinations of technologies for web developers to know these days. With its rich grouping of technologies, Ajax developers can create interactive web applications with XML-based web services, using JavaScript in the browser to process the web server response. Taking complete advantage of Ajax, however, requires something more than your typical “how-to” book. What it calls for is Ajax Hacks from O’Reilly. This valuable guide provides direct, hands-on solutions that take the mystery out of Ajax’s many capabilities. Each hack represents a clever way to accomplish a specific task, saving you countless hours of searching for the right answer.

Ajax is short for “Asynchronous JavaScript+CSS+DOM+XMLHttpRequest.” Even if you weren’t intimidated before, that tidbit is probably enough to make you reach for the Excedrin. Just reach for Ajax For Dummies instead. With screen shots, actual code and explanations, and live Web sites where you can see Ajax applications doing their thing, it will have you using Ajax to create Web applications that look an act like desktop applications in no time. With Ajax, you can speed up and clean up your Web applications. Shoppers at your online store can fill their carts without waiting for multiple page refreshes. Searchers on your sites can get instant results on the same page. This guide takes you on a tour of how Ajax is used today, complete with examples of Ajax applications in action, such as an Ajax-enabled Yahoo! search or an Ajax-based chat application. Then it gives you basics on using JavaScript.

Ajax burst onto the Web development scene by offering highly interactive, desktop-like Web applications that can be deployed through any modern Web browser without the need for special plug-ins. Ajax is built on existing Web technologies such as JavaScript, HTML, and CSS, and it is used in conjunction with your favorite server-side language. Foundations of Ajax explains how to combine these technologies effectively to implement Ajax into your new or existing Web applications. Like you, we are developers who are “in the trenches,” tasked with building Web-enabled applications that provide real value to our customers. As the Web continues to grow, the demand for more expressive and engaging interfaces will continue to increase. Much of the early hype surrounding Ajax centered on its use by Internet powerhouses such as Google and Amazon. However, just because the initial forays into Ajax were pioneered by leading software development firms doesnt mean your application wouldnt also benefit from these techniques. You already know how to develop Web applications, so this book uses specific, focused examples to teach the Ajax tools and techniques youll need to bring your applications to life. Armed with this book and your existing development expertise, you too will be able to apply Ajax techniques to your application to enrich the end users experience. When we first saw the potential of Ajax, we knew we had to start leveraging it for our own applications. Along the way weve learned some hard-earned knowledge that we thought needed to be shared with the rest of the development community. With this book youll be able to easily extend your own applications with Ajax and have fun while doing it. We hope that someday well be reading about your great Ajax-enabled application!

Web users are getting tired of the traditional web experience. They get frustrated losing their scroll position; they get annoyed waiting for refresh; they struggle to reorient themselves on every new page. And the list goes on. With asynchronous JavaScript and XML, known as “Ajax,” you can give them a better experience. Once users have experienced an Ajax interface, they hate to go back. Ajax is new way of thinking that can result in a flowing and intuitive interaction with the user. Ajax in Action helps you implement that thinking–it explains how to distribute the application between the client and the server (hint: use a “nested MVC” design) while retaining the integrity of the system. You will learn how to ensure your app is flexible and maintainable, and how good, structured design can help avoid problems like browser incompatibilities. Along the way it helps you unlearn many old coding habits. Above all, it opens your mind to the many advantages gained by placing much of the processing in the browser. If you are a web developer who has prior experience with web technologies, this book is for you.
