Suitable for learning basic programming for Web browsers, Beginning JavaScript is a patient, introductory tutorial on writing scripts successfully. It teaches you how to create client-side scripts (including full coverage of fundamentals like variables and flow control, plus plenty of screen shots.)

JavaScript is a good way to learn programming. It's powerful, of course, but the book takes small steps, using scripts that work with string and time data first, and then moving to manipulating browser objects like forms and windows. A running case study for a trivia game helps anchor the steps with a practical (and fun) example. There are plenty of tips on debugging your scripts (including how to use the Microsoft Script Debugger tool), and each section includes sample questions. (The book also offers extensive answers in over 80 pages at the end of the book.)



There's plenty of material on the differences between Internet Explorer and Netscape, especially when it comes to Dynamic HTML (DHTML). Coverage of the Document Object Model (DOM) for browsers helps bring the text up to date on some of the latest standards in Web browsers (including the new Netscape 6).



While the focus of Beginning JavaScript clearly is on the client, later sections turn to server-side ASP development (in which the sample trivia game is enhanced with ASPs written in JavaScript using ADO and Microsoft Access.) Reference sections on JavaScript and the browser object model for Internet Explorer and Netscape (through version 4.x) round out the material.



In all, with its approachable style and clearly rendered code examples, Beginning JavaScript makes for a worthwhile first book of programming for today's browsers. Even if you haven't programmed before, this text can give you the tools you need to bring your static Web pages to life. --Richard Dragan

Book Description

What is this book about?

JavaScript is the preferred programming language for Web page applications, letting you enhance your sites with interactive, dynamic, and personalized pages. This fully updated guide shows you how to take advantage of JavaScript's client-side scripting techniques for the newest versions of Netscape and Internet Explorer, even if you've never programmed before.



You begin with basic syntax and learn about data types and how to structure code for decision-making. Then you learn to use dates, strings, and other basic objects of JavaScript. Next, you see how to use JavaScript to manipulate objects provided by the browser, such as forms and windows. From there, you move into advanced topics like using cookies and dynamic HTML.



After you have a solid foundation, you explore dynamic generation of Web content using server-side scripting and back-end databases. And you practice what you learn by building a sample application as you go.
