　　创建一个简单的脚本，实现对网络连接性的检测。如下代码：

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
    checkConnection();
}
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]); //检测当前是哪种网络
}
