【分享经验】判断APP是否连接上网络

废话不多说，直接上代码

function isNetWork() {  
    var NetStateStr = '未知';  
    var types = {};  
    types[plus.networkinfo.CONNECTION_UNKNOW] = "未知";  
    types[plus.networkinfo.CONNECTION_NONE] = "未连接网络";  
    types[plus.networkinfo.CONNECTION_ETHERNET] = "有线网络";  
    types[plus.networkinfo.CONNECTION_WIFI] = "WiFi网络";  
    types[plus.networkinfo.CONNECTION_CELL2G] = "2G蜂窝网络";  
    types[plus.networkinfo.CONNECTION_CELL3G] = "3G蜂窝网络";  
    types[plus.networkinfo.CONNECTION_CELL4G] = "4G蜂窝网络";  
    NetStateStr = types[plus.networkinfo.getCurrentType()];  
    return (NetStateStr === "未知") || (NetStateStr === "未连接网络") ? false : true;  
}  
mui.plusReady(function () {  
        if(!isNetWork()){  
            mui.toast('没有网络~');  
        }  
});
