Introduction What Does This Book Cover? This book is divided into 13 chapters as follows: ❑ ❑ ❑ ❑ ❑ ❑ ❑ ❑ ❑ ❑ ❑ ❑ ❑ Chapter 1, “Introduction to Ajax on ASP.NET,” introduces the topic of Ajax with .NET. The chapter provides some background on development trends. We look at the parallels between PC development trends and web-based development trends. Chapter 2, “Introduction to DHTML,” introduces the concept of Dynamic HTML. The ability to dynamically change the HTML within a page is a core piece of making Ajax work. Chapter 3, “JavaScript and the Document Object Model,” talks about the role of JavaScript and the DOM. Chapter 4, “The XMLHttpRequest Object,” discusses the XmlHttpRequest object and how it is used to communicate between the client web browser and the server. The XmlHttpRequest object is the object that makes Ajax really go. Chapter 5, “Data Communication: XML, XSLT, and JSON,” presents an overview of XML, XSLT, and other ways to send data between the client and the server. Chapter 6, “What Is Built into ASP.NET,” discusses the various Ajax-type features that are built into the ASP.NET 2.0 release. Chapter 7, “Ajax.NET Professional Library,” introduces the Ajax.NET Pro library. This is an open source library that has garnered significant interest in the ASP.NET community. Chapter 8, “Anatomy of Ajax.NET Pro Library,” takes a deep dive into the Ajax.NET Pro library and looks into how the library performs all of its magic. Chapter 9, “Other Ajax Libraries for .NET,” introduces the reader to several other ASP.NEToriented libraries. Chapter 10, “Atlas Client Script,” introduces and discusses the client scripting environment in Microsoft’s Atlas. Chapter 11, “Atlas Controls,” discusses the building and using of controls in Microsoft’s Atlas environment. Chapter 12, “Atlas Integration with ASP.NET Services,” shows how to integrate Microsoft’s Atlas with many of the services available in ASP.NET 2.0 Debugging with Ajax can be problematic. That’s why Chapter 13, “Debugging,” discusses the options for debugging client-side Ajax applications. Conventions To help you get the most from the text and keep track of what’s happening, we’ve used a number of conventions throughout the book. Boxes like this one hold important, not-to-be forgotten information that is directly relevant to the surrounding text. xx
