I am having an unusual problem. When I first use your examples (on a MacBook Pro, OSX Mountain Lion, latest edition, using MAMP Pro) in Dreamweaver, they work (Chapter 15, test.html and calculator.html). However, after I make a change to a file, following your ebook, the html files cannot seem to locate jQuery. So, I try the original example again, and it now does not work. I am puzzled!
I also use Textastic on my iPad (3rd generation) and your examples work fine. (However, it could be just due to the fact that the iPad does not support server-side access and programming.)
I checked on Adobe's website and the recommendation is to delete the personal MacFileCache ---.dat file (which I did, and the problem still continues), then to try deleting the entire personal Configuration folder (which I did, and the problem still continues).
HELP!!!
