On OSX, navigator.onLine always returns true, except if I check the 'Work offline' option within the File menu. If there are no active connections navigator.onLine shoulds returns false as Chrome does.
(I *think* this is a dup and done on purpose, but could be wrong.)
http://www.whatwg.org/specs/web-apps/current-work/#dfnReturnLink-0 "The navigator.onLine attribute must return false if the user agent will not contact the network when the user follows links or when a script requests a remote page (or knows that such an attempt would fail), and must return true otherwise."
Yes. What if you're with dial-up connection? You don't have connection open, but clicking a link might open it, no?
Yes they are case where opening a link works without having a 'proper' Internet access. But I would say the most common case is probably the one to take into account. If the system network API (such as networkmanager on Linux) says there a no connection opened, maybe navigator.onLine should returns false. Or maybe the solution is for the Web App to 'ping' a URL.
Again, IIRC, this is a dup, and this has been discussed elsewhere. I don't recall all the details.
(but I agree that it would be good if .online would be actually more useful than what it is now.)
Note bug 620472, which seems to be where the current behavior was implemented.
Looks like a dupe of bug 654579 to me.
Agreed on duping after some bugzilla investigation today; I'm duping into bug 654579 and will update its subject to also include this subject, for clarity.
