A beginners guide to OpenLayers, but also to programming,
Verified Purchase(What is this?)
This review is from: OpenLayers 2.10 Beginner's Guide (Paperback)
I bought this books as a programmer needing to learn OpenLayers. It did the job, but at a painfully slow pace. The bulk of it seems to focus on teaching the basics of programming and explaining the obvious in relation to what is going on, which caused me to end up skim-reading and possibly missing out on some important points.
Code examples in the book can get a bit repetitive at times as each time you create a new map, you're seeing the same boilerplate code and instructions re-pasted into the book. In my opinion it also does not promote very good style. Use of global variables seem to be encouraged and there is even an exercise about how to move variables into the global scope - for those who don't know what globals are. There also was at least one example of an object literal with a comma trailing the final key:value pair. This works in Firefox, the browser of choice for this book, but can fail in others.
On a positive note I found the book easy to follow and it covers quite a wide range of features. It is certainly accessible. Use of firebug to demonstrate what's going on is nice too. I would have preferred a little more information about projections, but other than that not bad.
