phonegap得到wifi狀態 (phonegap get wifi status)

參考:
http://docs.phonegap.com/en/1.7.0/cordova_connection_connection.md.html#connection.type_full_example

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();

但是在C:\my-app\plugins
phonegap plugin add org.apache.cordova.network-information
不然會沒有反應 , 但是在官方文件沒提到這件事
但是再另一份卻有找到 http://docs.phonegap.com/en/edge/cordova_connection_connection.md.html#Connection
關鍵字 navigator.network 搜尋看看 , 文件目前寫的似乎不夠仔細.
