mui determines the current network type
MUI judges the current network type and introduces the native api
mui.plusReady(function(){
// plus.networkinfo.CONNECTION_UNKNOW = "未知";状态码：0
// plus.networkinfo.CONNECTION_NONE = "无网络链接"; 状态码：1
// plus.networkinfo.CONNECTION_ETHERNET = "有线网络"; 状态码：2
// plus.networkinfo.CONNECTION_WIFI = "无线网络"; 状态码：3
// plus.networkinfo.CONNECTION_CELL2G = "蜂窝移动2G网络"; 状态码：4
// plus.networkinfo.CONNECTION_CELL3G = "蜂窝移动3G网络"; 状态码：5
// plus.networkinfo.CONNECTION_CELL4G = "蜂窝移动4G网络"; 状态码：6
if(plus.networkinfo.getCurrentType()!=3){
// 3为状态码，wifi状态码是3
//
mui.toast("正在使用蜂窝移动网络");
