    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.CELL]     = 'Cell generic connection';
    states[Connection.NONE]     = 'No network connection';
    alert('Connection type: ' + states[networkState]);
}
checkConnection();

states[Connection.CELL_4G]  = 'Cell 4G connection';
states[Connection.CELL]     = 'Cell generic connection';
states[Connection.NONE]     = 'No network connection';
alert('Connection type: ' + states[networkState]);
}

API Change

Until Cordova 2.3.0, the Connection object was accessed via
navigator.network.connection, after which it was changed to
navigator.connection to match the W3C specification. It’s still
available at its original location, but is deprecated and will
eventually be removed.

iOS Quirks

  • iOS cannot detect the type of cellular network connection.
    • navigator.connection.type is set to Connection.CELL_2G for all cellular data. This is deprecated as of 2.6.0 and will be changed to return Connection.CELL in a future release.

Windows Phone Quirks

  • When running in the emulator, always detects navigator.connection.type as Connection.UNKNOWN.
  • Windows Phone cannot detect the type of cellular network connection.
    • navigator.connection.type is set to Connection.CELL for all cellular data.

Tizen Quirks

  • Tizen can only detect a WiFi or cellular connection.
    • navigator.connection.type is set to Connection.CELL_2G for all cellular data.
