Consistent with other members of Peachpit's Visual QuickStart Guide series, this title makes wise use of side-by-side explanations and screen shots, as well as code snippets and their analysis. This approach gives readers the feeling that the authors are sitting by their side and showing them how to code scripts. Most subjects are handled with numbered steps, such as "Validating Zip Codes," and useful tips punctuate the text.
The book introduces the whole concept of JavaScript in a fast-moving but readable chapter and then moves into solving real-world challenges. The authors do a good job of covering JavaScript's capabilities, from eye-catching graphics tricks to data-entry form processing and cookie management. Particularly enjoyable is the way the book spells out many of the differences between Netscape and Microsoft dynamic HTML approaches.
The JavaScript object model is laid out in an appendix, along with object compatibility between various browser flavors. To complement the book, the publisher offers a Web site that makes all of the example code easily downloadable for your use. This is a great little guide for both busy coders and JavaScript novices. --Stephen W. Plain

This book is for beginners and intermediates who are comfortable with HTML and lack the time to learn how to implement JavaScript from scratch or without resources. Negrino and Smith set up the book by the "things" you want your Web site to do rather than walk you through all the definitions, objects, operators, syntax, and all that stuff that would make the non-programmer's eyes glaze over. There are other books that serve that purpose.
Open the book and go to the table of contents, find what you need, and start adding it to your Web pages. Screenshots and lines of code are on every page of the book with step-by-step guidelines of how to use and implement the script. You don't even have to type the code from scratch. Instead, go to the book's companion Web site to get the code and fix it up to meet your needs - a great time saver.
If you own an earlier edition of the book, this one has 100 more pages of new material including new chapters on 7 - Forms and Regular Expressions, 11 - CSS, 13 - User Interface Design with JavaScript, 14 - Applied JavaScript, and 15 - Bookmarklets. Furthermore, the scripts in the older editions have been revised to ensure compliance with current Web standards.
Chapter 7 - Forms and Regular Expressions show how to validate email addresses, file names, and URLs. It gives you a gentle introduction to regexes (regular expressions). Don't panic at the thought of them especially with the handy table of expressions and associated characters. Once you try them out, you'll wonder what you ever did without them.
Chapter 13 - User Interface Design with JavaScript gives you the opportunity to create pull-down and sliding menus. Chapter 14 - Applied JavaScript has directions for creating a slideshow with captions and generating bar graphs.
Colorful additions to the book are the Object Flowchart and Object Table printed in color to show you which objects are compatible with which browsers. The flowchart may be a challenge for beginners, but the table makes up for it by listing the object along with its properties, methods and event handlers.
If you're looking to get cooking with JavaScript, look no further than this cookbook with easily modifiable recipes. It belongs on the Web designer's reference shelf.
