Hello
i try to detect if phone is connected to internet
i try this script from phonegap but he don’t work

function checkConnection()
   {       
    var networkState = navigator.network.connection.type;        
    var states = {};        states[Connection.UNKNOWN]  = 'Unknown connection';
    states[Connection.ETHERNET] = '1';        
    states[Connection.WIFI]     = '1';        
    states[Connection.CELL_2G]  = '1';        
    states[Connection.CELL_3G]  = '1';        
    states[Connection.CELL_4G]  = '1';        
    states[Connection.NONE]     = '0';
    if (states[networkState]=='0')
    {
    alert(No connection.');
    }

phoneui.documentReadyHandler = function() {
  
  checkConnection();
}
}

can you help me
of course i generated an ipa file to test on my phone.
thanks

Hi,

the phoneui.documentReadyHandler = function() is inside of your checkConnection() function. So it is never called.

Try:

phoneui.documentReadyHandler = function() {

checkConnection();
}

function checkConnection()
{
var networkState = navigator.network.connection.type;
var states = {}; states[Connection.UNKNOWN] = ‘Unknown connection’;
states[Connection.ETHERNET] = ‘1’;
states[Connection.WIFI] = ‘1’;
states[Connection.CELL_2G] = ‘1’;
states[Connection.CELL_3G] = ‘1’;
states[Connection.CELL_4G] = ‘1’;
states[Connection.NONE] = ‘0’;
if (states[networkState]==’0′)
{
alert(No connection.’);
}
}

Didn´t check, hope it works.

Hello Kale
thanks for your answer but it’s an error of copy/paste
in my script my function is outside phoneui.documentReadyHandler = function
Thanks

Hi,

the problem could be, that a phonegap function is called, before the phonegap framework is fully loaded.

Try this:

phoneui.documentReadyHandler = function() {
document.addEventListener(“deviceready”, onDeviceReady, false);
}
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’;

if (states[Connection.NONE]){
alert(‘No Connection!’);
}

alert(states[networkState]);
}

Should work now.

Hello Kale
thanks again, now i’ve an alert with “no connection” even though I am connected 🙁
so i test another way by testing a response.statut with xmlHttpRequest with success but i would like use

if (req.readyState == 4) {
       // only if "OK"
         if (req.status == 200 || req.status == 304) {
           results = req.responseText;
           document.getElementById(target).innerHTML = results;
       } else {
        
                     noInternet();
       }

function noInternet() 
   {    
       navigator.notification.vibrate(2500);
       navigator.notification.confirm(
            'Aucune connexion internet trouvée.',  // message
            onConfirm,              // callback to invoke with index of button pressed
            'Erreur',            // title
            'Close'          // buttonLabels
        ); 

but nothing happen, an idea?
thanks
Yann
