Learning JavaScript
Where can I can learn to write this type of program?

I'm pleased with the current result, but, sometime in the future, when I'll clean up the JavaScript code, generalize it, and make it easier to use. This will allow others, such as yourself, to use it to define their own animations with their own dancer icons.

In any case, there are several books on JavaScript available. I have the following 4 books:

1. Designing with JavaScript - Creating Dynamic Web Pages; by Nick Heinle; Sept. 1997; O'Reilly. ($29.95)
2. Dynamic HTML - by Danny Goodman; July 1998; O'Reilly. ($39.95)
3. Javascript Application Cookbook; by Jerry Bradenbaugh; Oct 1999; O'Reilly. ($34.95)
4. Javascript - The Definitive Guide; by David Flanagan; Jan. 1997; O'Reilly ($32.95)

Book #1 is a good introduction to JavaScript book, easy to understand, and has many examples.

Book #2 is a wonderful reference book. I use it all the time to look up HTML tags, CSS information, DOM, and Javascript commands. For me, it's indispensible.

Book #3 is somewhat boring (for me, anyway --probably because it was too easy). It might be an appropriate book for a beginner.

Book #4 is a reference guide, which I use as I need it. It has about 30 yellow sticky tabs on it right now, which means there's still a lot of useful information I need to learn.

BTW, I try to minimize the use of JavaScript on my site. I use JavaScript only when absolutely necessary. Almost all of my web script programming is done in PHP.
