When to use Ajax
This is just the first of three chapters on Ajax. The next chapter deals with how to use XML to share information between a web browser and a webserver. Chapter 16 gets you started with writing programs that run on webservers and communicate with the Ajax you learned in this chapter and that you'll learn in Chapter 15.
