By leveraging a number of existing and popular technologies, Ajax allows Web applications to make quick updates to the user interface without reloading the entire browser page. It is an ideal resource for developers who want to get started with Ajax-oriented Web developments using current technologies, in particular, Atlas.
This is the first book to show how PHP and Javascript technologies can work together to create next generation applications. Covering many of the most commonplace topics developers encounter in daily web application development tasks, The author guides readers through topics like enhanced forms validation, data display and manipulation, JavaScript debugging, and security considerations. The result is a book that not only discusses how two of the world's most talked about technologies can come together to create amazing applications, but is also based upon a real-world context, enabling developers to immediately begin applying what they've learned to their own situation.
Using proven examples and explaining concepts step by step, this book shows you how building Ajax-enabled sites and applications allows more interactive user interfaces than ever before. You’ll learn about the differences in capabilities between client-side and server-side development techniques, as well as how Ajax crosses this boundary. You’ll also discover how Ajax techniques can be summed up by patterns (which are development models that you’ll use repeatedly). With a mastery of these techniques, you’ll be able to breathe new life into your Web sites.
This is the most up-to-date book on JavaScript available, covering current standards, techniques, and practices. It provides all you need to know to hit the ground running, without making you trawl through hundreds of pages of syntax. The book contains multiple chapters on Ajax and DOM Scripting, which are two of the hottest web development and design tools available today. Using a pragmatic and thorough approach, the book ensures that even the most novice JavaScript programmers will become familiar and comfortable using the tools presented.
There has been a huge surge in interest in ‘Web 2.0’ technologies over the last couple of years. Microsoft’s contribution to this area has been the ASP.NET AJAX and Silverlight technologies, coupled to a supporting framework of ancillary tools. This book aims to be a no nonsense introduction to these technologies for the rapidly growing number of people who are realizing that they need Microsoft-based ‘Web 2.0’ skills on their CV. It gives people a grounding in the core concepts of the technologies and shows how they can be used together to produce the results that people need. The author has unparalleled experience of introducing people to these technologies.
The Google Maps API remains one of the showcase examples of the Web 2.0 development paradigm. In fact, interest in the Google service is so strong that it arguably sparked the mashup phenomenon. This is the first book to comprehensively introduce the service from a developer perspective, showing readers how they can integrate mapping features into their Web applications. Proceeding far beyond creating a simplistic map display, readers are shown how to draw upon a variety of data sources such as geocode.us and the U.S. Census Bureau’s TIGER/Line data to build comprehensive geocoding services for mapping any location in North America.
Reusable components and patterns for Ajax-driven applications Ajax is one of the latest and greatest ways to improve users’ online experience and create new and innovative web functionality. By allowing specific parts of a web page to be displayed without refreshing the entire page, Ajax significantly enhances the experience of web applications. It also lets web developers create intuitive and innovative interaction processes. Ajax for Web Application Developers provides the in-depth working knowledge of Ajax that web developers need to take their web applications to the next level. The book shows how to create an Ajax-driven web application from an object-oriented perspective, and it includes discussion of several useful Ajax design patterns. This detailed guide covers the creation of connections to a MySQL database with PHP 5 via a custom Ajax engine and shows how to gracefully format the response with CSS, JavaScript, and XHTML while keeping the data tightly secure. It also covers the use of four custom Ajax-enabled components in an application and how to create each of them from scratch. The final section of the book combines the individual code examples and techniques from earlier chapters of the book into one larger, Ajax-driven application—an internal web mail application that can be used in any user-based application, such as a community-based web application. Readers will learn not only how to create and use their own reusable Ajax components in this application but also how to connect their components to any future Ajax applications that they might build.

Step-by-step guide reveals best practices for enhancing Web sites with Ajax A step-by-step guide to enhancing Web sites with Ajax. Uses progressive enhancement techniques to ensure graceful degradation (which makes sites usable in all browsers). Shows readers how to write their own Ajax scripts instead of relying on third-party libraries. Web site designers love the idea of Ajax--of creating Web pages in which information can be updated without refreshing the entire page. But for those who aren't hard-core programmers, enhancing pages using Ajax can be a challenge. Even more of a challenge is making sure those pages work for all users. In Bulletproof Ajax, author Jeremy Keith demonstrates how developers comfortable with CSS and (X)HTML can build Ajax functionality without frameworks, using the ideas of graceful degradation and progressive enhancement to ensure that the pages work for all users. Throughout this step-by-step guide, his emphasis is on best practices with an approach to building Ajax pages called Hijax, which improves flexibility and avoids worst-case scenarios.
