Detect the Internet connection is offline?

Question

How to detect the Internet connection is offline in JavaScript?

Answer 1

Here is a snippet of a helper utility I have. This is namespaced javascript:

network: function() {
    var state = navigator.onLine ? "online" : "offline";
    return state;
}

You should use this with method detection else fire off an 'alternative' way of doing this. The time is fast approaching when this will be all that is needed. The other methods are hacks.
