 Part I: Getting StartedChapters 1 and 2 get you started on your tour of Ajax. Here, you get an overview of how Ajax is used today, and what it has to offer. There are many applications available that use Ajax, and you see a good sampling in this part. Then you get a solid grounding in JavaScript, the programming language Ajax is built on. (If you’re already a JavaScript Meister, feel free to skip this material.) To use Ajax, you have to use JavaScript, and in this part, you build the foundation that the rest of the book is based on. Part II: Programming in Ajax In Chapters 3 and 4, you delve into Ajax programming for real. Here, you see how to grab data from the server — whether that data is plain text or XML — and how to put that data to work. To illustrate how these techniques work, you see plenty of examples using Ajax, Dynamic HTML to update Web pages without needing a page refresh, and even advanced techniques like connecting to Google behind the scenes for real-time same-page Web searches. Part III: Ajax Frameworks Ajax can involve a lot of programming involved, and Part III takes a look at some of the many shortcuts that are available. Rather than reinventing the wheel yourself, you can use the Ajax frameworks. These frameworks are free and do most of the programming for you, so you’ll definitely want to check out this part. You can find all kinds of Ajax techniques, such as using Ajax for drag-and-drop operations, pop-up menus, downloading images behind the scenes, and more. Part IV: In-Depth Ajax Power Chapters 8 to 10 give you even more of the Ajax story. Chapter 8 is all about working with XML in JavaScript, and that’s what you often do in Ajax. In this chapter, you discover how to deal with XML documents that can get pretty complex, extracting the data you want, when you want it. Chapter 9 gives you the story on Cascading Style Sheets (CSS), which offer all kinds of options to display the data you fetch from the server using Ajax techniques. Because using Ajax means displaying data in a Web page without a page reload, using CSS is a big part of Ajax programming. Chapter 10 is about another big part of Ajax programming — writing code for the server so that you can send data back from the server to the browser. Like most Ajax books and Ajax samples you can find on the Internet, this book uses PHP on the server. You won’t need to know PHP to read this book, but it’ll help when you start using Ajax yourself, so Chapter 10 gives you a foundation in writing and working with PHP. Part V: The Part of Tens No For Dummies is complete without a Part of Tens. Chapter 11 is all about ten Ajax design issues you’re going to run into — and what to do about them. For example, working with web pages interactively, as Ajax does, means that the browser’s Back button isn’t going to work if the user wants to undo a recent update. You’ll find some of the solutions that have been attempted discussed in Chapter 11. Chapter 12 introduces you to ten essential Ajax resources. Knowing where to find these resources, and the Google groups and Ajax discussions on the Internet, will let you join the worldwide Ajax community. Download ebook on javascript: Ajax For Dummies
