Phonegap 3.6.3连接

Question

我正在尝试运行phonegap连接代码。这是我的脚本，我已经安装了网络插件。

document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady()
 {
    checkConnection();
}

function onBodyLoad() {
  alert('body load');
    checkConnection();
}

function checkConnection() {
    networkState = navigator.connection.type;
    alert('checkConnection');
    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]);
}

但我得到Uncaught TypeError: Cannot read property 'type' of undefined。

任何人都可以建议我哪里出错了吗？
