Chapter 8: Dynamic Forms

The JavaScript & DHTML Cookbook is all about adding value to the content of a web page. The book focuses on practical and sensible applications of scripting, rather than flying images and gratuitous color changes. For every problem Goodman addresses, there's a solution or "recipe"--a focused piece of code that web developers can insert directly into their applications. Yet, rather than just cut-and-paste code, you also get explanations of how and why the code works, so you can learn to adapt the problem-solving techniques to your designs.
