If you want to detect through WebKit or Safari. You can use
|navigator.onLine|
Which will indicate online or offline
I think I remember reading that onLine can give false positives (i.e.
that it can say you are online when you really aren't)
So you might want to double-check that navigator.onLine is reliable
enough for your application. I decided it was not reliable enough for
'reachability testing' as required by Apple for acceptance into the app
store.
I started a reachability plugin for iUI that uses ajax calls to make
sure a server can actually be reached. It is a "sandbox" extension and
I have only tested it briefly, but it might be helpful to someone.
The code is in Mercurial (source control) here:
http://code.google.com/p/iui/source/browse/#hg/web-app/iui/ext-sandbox/reachability
There is a live demo here:
http://iui-js.appspot.com/iui/ext-sandbox/reachability/reachability-demo.html
It requires that you pull an unreleased version of iUI from source
control in order to use it. (or wait for iUI 0.40-dev3)
