Dedication

To Jesse James Garrett:

For recognizing that "something special was in the air" in web applications development; for coining the term "Ajax" (Asynchronous JavaScript and XML) to name that

phenomenon; and for your tireless efforts in promoting Ajax

—a key set of technologies defining Web 2.0.

Perhaps most important, the book presents hundreds of

The early chapters present a carefully paced introduction to

"client-side" web programming, using the popular JavaScriptlanguage and the closely related technologies of XHTML

(Extensible HyperText Markup Language), CSS (Cascading StyleSheets) and the DOM (Document Object Model) The material inthe JavaScript chapters presents a solid foundation for the

deeper treatment of scripting in the Adobe Flash, Adobe Flex,PHP and Ruby on Rails chapters later in the book Experiencedprogrammers will read the early chapters quickly and find thetreatment of scripting in the later chapters to be rigorous andchallenging

Today's users are accustomed to desktop applications with richgraphical user interfaces (GUIs), such as those used on Apple'sMac OS X systems, Microsoft Windows systems, various Linuxsystems and more Users want applications that employ themultimedia capabilities of graphics, images, animation, audioand video They want applications that can run on the Internetand the web and communicate with other applications Userswant to apply database technologies for storing and

development If you are a serious web developer, you'll want totest your web applications across many browsers and platforms.The examples for the book execute correctly on both Microsoft'sInternet Explorer 7 (IE7) and Mozilla's Firefox 2 (FF2) browsers.Most of the examples will also work in other browsers such as

easily build Ajax-based applications that operate across a widevariety of browsers and browser versions without your having to

be concerned with the low-level details

The third part of the book, Chapters 13–24, focuses on both theclient and server sides of the GUI and the graphical part of RIAdevelopment Here we cover client-side technologies such asAdobe Flash and Adobe Flex that use, or can be combined with,Ajax or Ajax-like capabilities to develop RIAs Each of these

technologies also can consume web services Next, we presentthe server side of web application development with discussions

of web servers (IIS and Apache), databases, server-side

scripting languages such as PHP and Ruby on Rails, and severalserver-side frameworks such as ASP.NET 2.0 and Java-ServerFaces We complete our server-side discussion with a chapter

on building both SOAP-based and REST-based web services.You may have noticed that Chapter 13, Ajax-Enabled Rich

Internet Applications, overlaps the second and third parts of thebook Chapter 13 serves as a bridge from "raw" Ajax

development to "encapsulated" Ajax development with the Dojolibraries

Teaching Approach

AJAX, Rich Internet Applications and Web Development for Programmers contains a rich collection of examples The book

Objectives Each chapter begins with a statement of

objectives This lets you know what to expect and gives you anopportunity to determine if you have met the objectives afterreading the chapter

Quotations The learning objectives are followed by

quotations Some are humorous; some are philosophical; othersoffer interesting insights We hope that you enjoy relating thequotations to the chapter material

Outline The chapter outline helps you approach the material in

a top-down fashion, so you can anticipate what is to come andset a comfortable learning pace

Illustrations/Figures Abundant charts, tables, line drawings,

programs and program output are included

Programming Tips We include programming tips to help you

focus on important aspects of program development These tipsand practices represent the best we have gleaned from a

combined six decades of programming and teaching experience.One of our readers told us that she feels this approach is likethe highlighting of axioms, theorems and corollaries in

mathematics books—it provides a basis on which to build good

Good Programming Practices

Good Programming Practices call attention

to techniques that will help you produce programs that are clearer, more

understandable and more maintainable.

Common Programming Errors

Programmers tend to make certain kinds of errors frequently Pointing out these

Common Programming Errors reduces the likelihood that you'll make the same

mistakes.

Error-Prevention Tip

These tips contain suggestions for exposing bugs and removing them from your

programs; many describe aspects of programming that prevent bugs from getting into programs in the first place.

Performance Tip

These tips highlight opportunities for making your programs run faster or minimizing the amount of memory that they occupy.

Portability Tip

We include Portability Tips to help you write code that will run on a variety of platforms and to explain how to achieve a high

degree of portability.

Software Engineering Observation

The Software Engineering Observations highlight architectural and design issues that affect the construction of software systems, especially large-scale systems.

Thousands of Index Entries We have included an extensive

index which is especially useful when you use the book as areference

"Double Indexing" of Live-Code Examples For every

source-code program in the book, we index the figure captionboth alphabetically and as a subindex item under "Examples."This makes it easier to find examples using particular features
