You don't need the book to use the site since the authors have a great collection of scripts each with its own demonstration page. WebMonkey One of the best sites for learning about all parts of web site development, they also have a small but good collection of scripts and some excellent tutorials. I guess strange minds think alike. A good site to find Java script tutorials and some free scripts to use in your page. ZDNet DevHead JavaScript Also part of a larger site aimed at web developers.
Same caution applies.
In keeping with the Visual QuickStart Guide, this is a good reference book for those who want the basics fast with lots of step by step examples. The authors maintain a companion web site which is also excellent. A separate package called Actions Plus, add even more. Other products in the same catagory such as Dreamweaver, Fusion and FrontPage will do the same. Both of these programs are designed for creating web graphics but they will also build roll overs and other JavaScript effects dealing with images for you.
