Detect if phone is online/offline with PHONEGAP reachability API

Question

Hi and thanks in advance,

I'm aware Phonegap has a reachability API and I'd like to know how I can use it to detect if the phone is connected to the network or not.

What I found is here: http://github.com/phonegap/mobile-spec/blob/master/tests/network.tests.js

I just don't know how to use it or if it even suits my needs.

Thanks again.

With the newest update, the method for checking if the device is online has changed - check out the API documentation at http://docs.phonegap.com/phonegap_connection_connection.md.html#Connection.

Here is the code that they use as an example:

<script type="text/javascript" charset="utf-8" src="phonegap.js"></script>
<script type="text/javascript" charset="utf-8">

// Wait for PhoneGap to load
// 
document.addEventListener("deviceready", onDeviceReady, false);

// PhoneGap is loaded and it is now safe to make calls PhoneGap methods
//
function onDeviceReady() {
    checkConnection();
}

function checkConnection() {
    var networkState = navigator.network.connection.type;

    var states = {};
    states[Connection.UNKNOWN]  = 'Unknown connection';
    states[Connection.ETHERNET] = 'Ethernet connection';
    states[Connection.WIFI]     = 'WiFi connection';
    states[Connection.CELL_2G]  = 'Cell 2G connection';
    states[Connection.CELL_3G]  = 'Cell 3G connection';
    states[Connection.CELL_4G]  = 'Cell 4G connection';
    states[Connection.NONE]     = 'No network connection';

    alert('Connection type: ' + states[networkState]);
}

</script>
