Chapter 6

HTML Forms, Data, and Ajax

WHAT’S IN THIS CHAPTER?

• jQuery Data Appreciation
• Validating Forms With jQuery
• Using jQuery’s Ajax Methods

The three main topics of this chapter are closely related cousins. HTML forms contain and process data, an everyday operation of the Web. More often than not, form data is processed and posted to a server somewhere asynchronously, rather than the old-fashioned post-process-reload technique. Here, you explore one of the biggest revolutions in web development of the past 10 years — Ajax. You also learn how insanely easy jQuery makes it, simplifying asynchronous communication with the server side.
