how can check internet connection in cordova 3.0 build? because tried

but returns 0.

i heard jquery mobile don't know how use because tried

 function checkconnection(){   alert(navigator.online);} 

with jquery mobile library loaded returns true.

this happening on smartphone , on avd too.

can me?

you can check connection this:

function checkconnection() {      if( !navigator.network )      {          // set parent windows navigator network object child window          navigator.network = window.top.navigator.network;      }      // return type of connection found    return ( (navigator.network.connection.type === "none" || navigator.network.connection.type === null ||            navigator.network.connection.type === "unknown" ) ? false : true ); } 

returns true connection , false no connectivity.

in android manifest, use following permission:

<uses-permission android:name="android.permission.access_network_state" /> <uses-permission android:name="android.permission.internet" /> 

edit: handles windows in iframes well. added permission.
