Check connection with WinJS

Background 

Checking the state of the network can have very different results: wired connected with or without internet, GSM, an so on. If you only want to know if the user is connected to the internet there isn't any short way, so I made this litle check to have as a snippet of code to our apps.

Using the code

Just copy-paste and use this code: 

var cx = new Windows.Networking.Connectivity.NetworkInformation.getInternetConnectionProfile();

if ((!('getNetworkConnectivityLevel' in cx)) || ((cx.getNetworkConnectivityLevel()) < 3)) {
   alert('Debes estar conectado a internet para ver el contenido. Revisa tu conexión y vuelve a intentar.', 'Atención');
   return false;
}
