I have the electronic version (pdf) of this book and can say that it is an excellent introduction to jQuery and Javascript. Having the pdf means that all the code is structured with colour as well as logical formating which makes it a pleasure to read.I particularly like the authors style and approach, in beginning with simple examples and explaining the sometimes complex syntax as he goes along. I learnt so much from just a few chapters of this book than all the other trawling on the web, and I was applying the material to a web site within a few minutes.Nice to haves? If I had a wish list it would have been more detailed discussion of the various plugins, especially jQuery-UI. Whilst the treatment given was good, indeed I like the way he provided a custom style sheet for developing dialogues, it was introductory, and if I had any influence over the publishers it would be to take each section to the next level. For example dynamic loading of html etc. Lastly, I wonder when Wrox is going to change their branding? Having some of their books from over 10 years ago, I naturally associate the current branding with these old books, which if unchanged, in comparsion with today's books, leaves a great deal to be desired.
