DOM Scripting

Simon P. Chappell writes "This is an unusual book in a good way. It covers a subject normally the preserve of geeks while being targeted at designers. Not a common approach, but one that Jeremy Keith pulls off rather handily. Mr. Keith is an active member of the Web Standards Project's Scripting Task Force; he not only knows how to script web pages, but he knows how to use that scripting to enhance the page's conformance to standards and even increase a site's accessibility. If you are like me, and have put off working with JavaScript because of the standards issues, then this book is our notification that those days are behind us. If you are a web designer who is interested in using dynamic techniques to enhance your site, but had feared the wrath of the standards police, this book is for you."

summary	A tour de force that is destined to be called a classic.

I think that it's important to note that this is not a book about Ajax. For those of us feeling overly bombarded with Ajax this and Ajax that, this book is a delightful and refreshing read. Mr. Keith goes beyond the hype and brings us a strong explanation on one of the fundamental pillars of Ajax: working with the Document Object Model (the DOM of the title) using JavaScript. Without DOM Scripting there could be no Ajax, so this is an important addition to the library of any Web Developer who plans to create dynamic Web Applications. Who's it for?

According to the introduction: "This book deals with a programming language, but it isn't intended for programmers. This is a book for web designers. Specifically, this book is intended for standards-aware designers who are comfortable using CSS and XHTML." Mr. Keith is good to his word and his book is wholly targeted at web designers. That being said, I also found that the book was very suitable for programmers, myself included, who have been putting off using JavaScript in any depth. The Structure

The book's structure is fairly standard (no pun intended) and each chapter builds upon the proceeding one. The exceptions to this are the first and last chapters where the history of JavaScript and the future of DOM scripting are discussed, respectively.

Chapter two introduces JavaScript syntax and does a pretty good job considering that it is only 26 pages long. Chapter three then covers the Document Object Model. With the basic concepts of JavaScript and the DOM covered, the rest of the book proceeds to show us how to use them together.

Chapter four works through a basic JavaScript driven image gallery. This gallery is then revisited in chapter six where the JavaScript is upgraded to allow it to degrade gracefully according to the level of JavaScript functionality available in the browser and to ensure that the JavaScript is as unobtrusive as possible. Our final visit to the gallery example is in chapter seven where we learn to create markup on the fly and see how it can be usefully applied to enhance the gallery even further.

Chapter five looks at best practices for web design and how JavaScript and DOM scripting fit into that. Chapter eight takes a break from image galleries and looks at how DOM Scripting can help enhance our existing text content. Enhancement is also the focus of chapter nine, where the intersection and interaction of CSS and the DOM is explored.

Chapter ten is a little bit of fun, taking a look at animation through DOM Scripting. Chapter eleven, called "Putting It All Together" is a case study where a website is created for an imaginary band called "Jay Skript and the Domsters". The name may be corny, but the example is a wonderful display of starting with plain content and enhancing it using only standard compatible techniques. The book wraps up with an appendix of reference information of the JavaScript used in the book. What's to Like?

For a book that is not aimed at programmers, it is a great introduction to programming in JavaScript. Every concept is introduced clearly and the reasoning behind each approach is explained and the justification for it provided.

The book is very comfortable to read. The physical size, the typography, the design and the layout are all excellent. This is not surprising considering the target audience; excellent design is the minimum price of admission to the library of those in the design industry. What's to Consider?

There is very little that I did not like in this book. Although, I think that that it would be useful to point out again, that this isn't specifically written for programmers. If you know JavaScript well, this may not be the book for you. If you have extensive browser scripting experience this may also not be for you. And lastly, if you have no need, desire or interest in standards based scripting, this is absolutely not the book for you.

This is not a reference book. It will teach you a solid core of JavaScript suitable for working with the DOM, but do not think that it will teach you everything that there is to know about JavaScript. While the back of the book does have a small reference section, it is only for the concepts taught in the book. Website

Of course, the book has a website, available at domscripting.com. The site has an active blog and the finished version of the example site for "Jay Skript and the Domsters". Conclusion

This book deserves to be promoted to classic status immediately. It is written clearly, it uses only good principles of programming and adheres strictly to the appropriate standards. What a combination."
