Instead of drowning you in theoretical possbilities
and lengthy explanations, this Visual QuickProject Guide uses big illustrations
coupled with clear, concise step-by-step instructions to show you how to
complete a specifi c project in a matter of hours.
This particular book in the Visual QuickProject series teaches you how to
???roll your own??? Ajax-enabled application. The specifi c example will involve
managing employees in a company, organized by departments into a type of
address book. But the actual example is secondary to the technologies and
ideas being taught. By the end of this book, you??™ll have a nice, working
example; tons of usable code; and an education in Ajax that you can apply
to your own projects.

how Ajax works
Normally, when
a client??”the
user and their
Web browser??”
requests a Web
page, the server
handles the
request, sending
the data back to
the client. The
client loads the
data, redrawing
the browser with
the requested page. For each request, this process is repeated.
Ajax is one way to create Rich Internet Applications (RIAs): Web sites that
behave more like desktop applications.
