Produktbeschreibungen

Amazon.de

JavaScript is great, but at best it is a complementary language for Web development. JavaScript for the World Wide Web offers a productive, how-to style that lets you solve a problem or pick up a trick and then move on with the rest of your work.

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 an apple, not an orange, so don't call it an orange. It's not a comprehensive guide to the esoteric ins and outs of JavaScript. That's what O'Reilly's JavaScript: the Definitive Guide is for. This book --- like all the books in the excellent Visual QuickStart Guide series --- is aimed at getting you into the topic and doing stuff with it quickly. The other books like the O'Reilly book (which would leave a beginner pulling her hair out) are for later.
The examples in this book show you the most common uses of JS and provide sample scripts (which are available for download on the companion web site). The newer, 3d. ed. of the book adds a significant amount of additional information, and is worth the price of admission (I also owned the 2d. ed.). It gets you doing cool stuff with Javascript quickly. That simplicity is its strength and also one of my complaints about it.
The examples are not often very flexible. They do one thing well (which is described quickly and in a manner in which you can easily understand), but its not always easy to modify the script to similar uses. And, because it's how it is, it doesn't teach you enough to understand the theory of the JS you're using, so you rarely understand how to modify those scripts. BUT, as I said above, that's beyond the scope of this book.
One example: in the doing things with windows chapter, there are scripts for opening and closing a second window from within the main window. Great scripts and they work well. But, if you want to open the new window from the main window, then close the new window from the new window (not the main window), too bad, because it doesn't show you how to do that.
But, on that point, I'm starting to lean in the direction of calling this book an orange.

The JavaScript Visual Quickstart Guide has generated split reviews. Some people loved it and some others absolutely hate it. I'm about done with it, and here's what I have to say:
As far as learning the basics and the theory of JavaScript goes, this book is a disappointment. You won't be ready to generate your own codes from scratch unless your project is similar to the examples given in the book and require minor revisions. The style of the book is:
To achieve task A, type in code A.
To achieve task B, type in code B, etc..
If you're lucky, what you want to do matches one of the countless example codes in the book. The codes are explained very vaguely. For example in one of the codes, a 'return true' statement appears out of nowhere. The return concept has not been explained in the book, and the authors do not make clear where 'true' is being returned to and what consequences it will have. The explanation they have is: You need the 'return true' statement here to make sure the code will work. So, the book has a cut and paste approach, which rightfully upset some readers. But if you read the 'further reading' section at the end of the book, the authors admit that their book is intended for people who just want a code to work quick, and don't care why it works. I wish they made this clear in the foreword, so readers like me who actually want to learn JavaScript could look elsewhere.
As far as the 'copy this code, and it'll work' approach goes, the book is great. The authors claim that their upcoming book:'JavaScript Advanced Visual Quickstart Guide' will focus on the background of the language. That book may be worth a shot.

One of the most important aspects of any new language, be it spoken, written, or software-based, is the syntax and usage rules. This book, while advertised for the beginner and intermediate, skips over this most crucial aspect of learning javascript and delves immediately into example programming. I was on my third chapter, still waiting for the detailed discussion of javascript syntax before I realized that the two or so odd pages in chapter one was all I was going to get. I have spent hours trying to decipher their example code because I do not understand the fundamental constructs of the objects, methods, and event handlers. I am learning javascript, but mostly due to my existing knowledge of C and C++, not because of any teaching from this book. Short of copying the example code verbatim, I think most beginner and intermediate users will find that they do not have the understanding of javascript in which to solve unique problems on their web pages. If an exact example is not in the book, they will be unable to use their knowledge of javascript to deduce a solution. I found this book very disappointing, especially after really enjoying this "visual" approach in Elizabeth Castro's HTML for the World Wide Web. Advanced javascript users will undoubtedly pick up clever programming ideas from this book, but if you are actually trying to LEARN this language, you will be disappointed.

I was very disappointed. This is little more than another source of scripts to be copied. That is about all you can do with it because the authors do not take the time to explain or deconstruct the script into its component parts. Therefore, it is very difficult to customize any of the scripts for your own use. Don't even think about learning to write your own.
The "descriptive" text associated with each script, simply explains what each component does but does nothing to teach why it does it. For instance, the author writes: "The rest of the rollover gets handled in the link tag. When the user puts the mouse over the blue arrow graphic (onmouseover), the script swaps the blue arrow for the graphic with the red arrow." Besides the fact that most people at this stage are already familiar with what a "rollover" is, this has already been explained on the previous page. How about explaining why I get the error "document.listing is not an object" when I copied your script verbatim.
The fact is most of the scripts I attempted to implement resulted in errors and the authors give little or no assistance to help resolve them. There are much better resources for learning JavaScript. I was up and running from free Web based resources faster than you can say WOFTAM (Waste OF Time And Money).
