¿Qué aprendes en este curso?
This first lesson begins with a summary of what you need to get started. What you'll need to begin includes an understanding of HTML and, of course, a Web site that you can work with and are interested in making more responsive and dynamic. Then I'll give you an overview of Ajax so that you'll know exactly what it's capable of. In each lesson, we'll develop a computer game to help illustrate the topic of the day. The game for this lesson is the Joke of the Day application, which will give you a good, basic idea of how powerful Ajax can be.

Digging Deeper into Ajax
Working With XML
I'll begin Lesson 9 by introducing you to extensible markup language (XML), a standard for storing and transporting data in a platform-independent manner. I'll explain how to develop Ajax applications that can work with data stored in XML files. You'll learn how to create XML files and how to access their contents using Ajax. I'll also be showing you the basics of XML element syntax and how to formulate XML tags that include text content and optional attribute data. As usual, we have a cool application to create: Who Am I? This nifty application will retrieve data stored in different XML files located on the application's Web server.
Cascading Style Sheets
Cascading style sheets (CSS) isn't a formal Ajax component, but Ajax programmers have come to depend on it for all sorts of things. In this lesson, we'll talk about all the things CSS lets you do, including changing foreground and background colors; specifying font type, size, and color; turning things visible and invisible; and even moving things around the screen. We'll also cover how to work with inline, embedded, and external styles, and we'll wrap things up with the Fortune Telling Game application.
Ajax and PHP
PHP is a server-based scripting language designed to support the development of server-based programs, and that's what this lesson is devoted to. You'll learn how PHP scripts are capable of reading and writing files stored on Web servers and also how they can work with database-management systems. Learning how to create PHP scripts will give you the ability to develop server-based programs that support the needs and requirements of your Ajax applications. Our project application for this lesson, the Word-Guessing Game, makes good use of PHP.
Important Ajax Design Issues
We'll spend this last lesson addressing some design issues to help you avoid certain problems as you begin designing your own Ajax applications. As with any application-development framework, Ajax applications have a number of issues that you must be aware of. In some cases, solutions already exist, but in other cases, the jury is still out on the best way to handle things. I'll go over a number of Ajax development issues, and wherever possible, I'll suggest solutions or alternative ways of getting things done. We also have one last application project: the Login application. It'll incorporate much of what you've learned throughout the course.
