module.controller('MyCtrl', function($rootScope, $cordovaNetwork,$ionicLoading) {
  document.addEventListener("deviceready", function () {
    //var type = $cordovaNetwork.getNetwork()
    var isOnline = $cordovaNetwork.isOnline()
    var isOffline = $cordovaNetwork.isOffline()

    // listen for Online event
    $rootScope.$on('$cordovaNetwork:online', function(event, networkState){
	  var type = $cordovaNetwork.getNetwork()
      var onlineState = networkState;
	  if (type == Connection.WIFI) {
		//TODO something
	  }else if (type == Connection.CELL_4G || type == Connection.CELL_3G){
	  	//TODO something
	  }
    })

    // listen for Offline event
    $rootScope.$on('$cordovaNetwork:offline', function(event, networkState){
      var offlineState = networkState;
	  $ionicLoading.show({
          template: '网络异常，不能连接到服务器！'
      });
    })
