This event fires when an application goes online, and the device becomes connected to the Internet.
document.addEventListener("online", yourCallbackFunction, false);
The online event fires when a previously unconnected device receives a network connection to allow an application access to the Internet. It relies on the same information as the Connection API, and fires when the value of connection.type becomes NONE.
Applications typically should use document.addEventListener to attach an event listener once the deviceready event fires.
document.addEventListener("online", onOnline, false);
function onOnline() {
// Handle the online event
}

During initial startup, the first online event (if applicable) takes at least a second to fire, prior to which connection.type is UNKNOWN.
When running in the Emulator, the connection.status is always unknown, so this event will not fire.
The Emulator reports the connection type as Cellular, which does not change, so events will not fire.
