    var networkState = navigator.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.CELL]     = 'Cell generic connection';

Cambio de API

Hasta Cordova 2.3.0, el objeto de conexión era acceder a través de navigator.network.connection, tras lo cual fue cambiada a navigator.connection para que coincida con la especificación del W3C. Sigue estando disponible en su ubicación original, pero es obsoleto y eventualmente desaparecerá.

iOS rarezas

  • iOS no puede detectar el tipo de conexión de red celular.
    • navigator.connection.type is set to Connection.CELL for all cellular data.

Windows Phone rarezas

  • When running in the emulator, always detects navigator.connection.type as Connection.UNKNOWN.

  • Windows Phone no puede detectar el tipo de conexión de red celular.

    • navigator.connection.type is set to Connection.CELL for all cellular data.

Rarezas Tizen

  • Tizen sólo puede detectar un Wi-Fi o conexión celular.
    • navigator.connection.type is set to Connection.CELL_2G for all cellular data.
