[jdev] Simple JavaScript XMPP client example

Ok, so I have experimented a bit more, and as Steven said, if I host the
code on a server, the code works, but if I just access it locally, the code
does not work. I still don't quite understand why. If I access the code
locally from my machine, and then try to connect to a server on the web,
the domain where the code is hosted (my local machine) and the server
domain are different, but this is also the case if I host the code on a
server and try to connect to a server in another domain, which does work.
So I don't quite understand what is the problem then when I access the code
locally
