I have been making forms in Acrobat since version 3.0, and have a background in Dbase III, Foxpro, Visual Basic .NET, and SQL 2000. However, I never learned Javascript formally or in-depth.
This book was an excellent springboard to a good working knowledge of JavaScript, especially relating to Acrobat. The chapters are broken down by functionality and increase in complexity, and each has at least one project that the author will guide you step-by-step (you can download the PDF's from the author's website). The book was edited very well, I found only one mistake (a typo) after reading the book almost page for page. What makes this an outstanding book is the clarity of the examples and explanations the author has so obviously spent much time on to help us "poor newbies".
My focus was how to get started interacting with databases (SQL or Access), and while the first Chapter (16) was review for people familiar with databases, Chapter 17 really got me started. The project in the book gives the basics -- to go beyond, you need the following resources: the Acrobat JavaScript Scripting Reference and the Scripting Guide (...).
Developers know that the devil is in the detail, so once I got past the database interface hurdle, the other chapters were just as useful to put the necessary finishing touches on my project.
Here's the bottom line: If you are already advanced in your knowledge of JavaScript, this isn't your book! You know enough to pick up the Acrobat JavaScript Reference and figure it out. If you're just starting out or need to know, in detail, what capabilities Acrobat and JavaScript can give you for an IT solution, this book is an excellent resource.
One last thing that makes the author of the book outstanding: He has a free newsletter for those looking for better ways of utilizing Acrobat (...)
