Checks the active network connection that is being used.
This property is a fast way to determine the device's network connection state, and type of connection.
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'; alert('Connection type: ' + states[networkState]); } checkConnection();
