Ich als Diplom-Informatiker lese die Bücher aus der Heads-First-Reihe gerne, um mir einen ersten Überblick zu verschaffen. Man lernt schnell genug, um etwas selber anwenden zu können. Das war auch bei diesem Buch der Fall.
In jedem Kapitel wird ein neuer Auftrag eines Kunden vorgestellt, den der Leser dann unter Anleitung der Autoren selber erfüllen muss. Das gelernte Wissen wird also unmittelbar angewendet und auch in vielen Übungsaufgaben abgefragt.
Das ist an den meisten Stellen gelungen und interessant.
Ich gebe aus den folgenden Gründen nur 4 Sterne:
1. Im Buch werden ganz elementare Programmierkonzepte, wie Variablen und for-Schleifen ausführlich erklärt. Die Autoren haben als Zielgruppe wohl Leser ohne Programmiererfahrungen gehabt. Das ist meiner Meinung nach sinnlos und Platzverschwendung, denn es ist niemandem zu raten, mit jQuery Programmieren zu lernen.
2. Manche Stellen waren auch ein wenig langweilig (z. B. die Animationen und die Timer)
3. jQuery ist ein Teil der Präsentationsschicht. Diese soll nur zur Anzeige dienen und Geschäftsprozesse (Business-Logik) sollten nicht hier modelliert werden. Im Buch wird an vielen Stellen aus didaktischen Gründen hiergegen verstoßen, ohne das der Leser darüber aufgeklärt wird, das er hier ein "Don't" bzw. eine "Bad practice" lernt.
Alles in allem aber ein toller Einstieg in jQuery.
I haven't used jQuery before, and I wanted to see what it is all about. First of all, I like to learn by examples ' and you got them here. All in one piece ' zipped ' directly on your hard drive from the Head First Lab web page (each example contains corresponding jQuery library). This is nice. You simply don't have to copy-paste everything you see in the book into your text editor. When it comes to the content. Well, this is always hard thing to judge. I know people who hate Head First series. They say it is not sophisticated enough. I am, on the contrary, a great fan of Head First. jQuery, like any other Head First series book, gives you simple, straight overview of the topic. OK, it will not provide you with as much text as other books, but hey, 'A picture is worth a thousand words'. And you will find lots of them here. However, if you consider yourself a hacker, don't buy it. It's rather for beginners. If you are a beginner ' I'd consider buying it.
Auch jQuery überzeugt durch die einzigartige Vorgehensweise
in die Thematik einzufürhen.

For me, personally, there were a bit too many images, games, and repetition. I found it difficult to get in any kind of reading rhythm with the non-standard flow of text and information. It was kind of cute at first and overall I found the images and games appealing and useful, but it was a bit too much and too distracting for me. At times it felt more like a chore to learn the material.
Again, a great book for beginners that teaches a lot of breadth as opposed to depth. Lots of images for those that learn best visually. Prepare yourself for a different writing/learning style if you are not familiar with the Head First Series.

The tone is conversational and easy to read overall. The scenarios are contrived but do a decent job of highlighting the principles each chapter intends to cover. Presenting blocks of code with annotations in a handwritten style explaining what each piece of code does was very helpful, and I think this was the most successful aspect of this book. I could see some of the illustrated analogies (e.g. comparing variables to test tubes and arrays to test-tube holders) helpful for people who were less familiar with programming concepts. However, a lot of the other visuals that are supposed to make it more "fun" seemed unnecessary and childish.
Throughout the book there are many "fill in the blank" and "drop this line into a block of code" sort of exercises. Some are okay, but many of them don't really seem to test the right stuff especially in the later chapters. Often, the authors don't provide enough context for you to really understand what you're being asked to write, so it becomes a matter of guessing at where to put the lines of code based on the syntax (e.g. this CSS style must go here, this jQuery selector must go here, this must go here because it has an end brace, etc.) and not what the code is supposed to do. Other times, the blank that is being filled has nothing to do with the concept covered by the chapter or are so obvious as to be trivial. This was probably my biggest complaint about the teaching style. It made a lot of the exercises feel like busy work rather than truly educational.
Instead, I would have liked to see much more of "translate this logic from English to code" sorts of exercises. I felt like there was more of this in the first few chapters, but especially towards the end the book kind of cheats on the tougher topics by providing a block of code to just paste in when it would have been much more helpful to be guided through writing the code from scratch. This seemed lazy on the part of the authors and was disappointing.
There are a surprising number of typos which can make following along confusing if you're not paying attention. Since syntax is such a sensitive thing for programming, I considered this inexcusable and questioned whether the publishers should have spent more energy on quality-control rather than making the book "fun".
One of the first things that stands out about this book (and the Head First series in general) is the bright, colorful, and plentiful images used to help illustrate concepts and how jQuery works. They also provide illustrations on how to walk through the specific problem at hand, which is often nice to see in a visual format...even if it is just notes on a pad of paper. The other highlight of the Head First series (and this book is no exception) is that it's written in a clear easy to understand language, it's written for the novice programmer--one that's still learning how programming works and for someone that's looking for an overview of the language. In this book the authors give you a specific situation--a client wants work done on their website-- walk you through how to solve the problem step by step, and with illustrations to help you solve the problem. This method can be a very helpful way to introduce aspects of jQuery as it walks through problems that you might encounter when building/developing your website and ways that jQuery can over come that problem.
But like every "Head First" title the illustrations won't work for everyone. I find it helps if you're coming from a nontraditional background or from a more creative bent (left brain.) And even then sometimes the images and graphics can be overwhelming, which is a problem that I find sometimes in this book. I found that thT images, while helpful in the beginning, often start to become overwhelming as you get more and more into the problem being solved and make it a bit difficult at times to concentrate on following the step by step instructions.
Overall this is a fairly good introduction book and easy to read if you're coming from a nontraditional programming background (and are left brain) then this might just be the book for you to learn more about scripting languages. If you're more right brain then you might want to look for a more traditional book on jQuery, such as "Learning jQuery, Third Edition" from Pact.
