ionic app 监听网络功能

安装cordova插件：

cordova plugin add cordova-plugin-network-information

在app.js 的run()里面的function()注入$cordovaNetwork，然后就可以监听网络的链接状态和断开状态了，部分代码如下：

    .run(function($ionicPlatform,$state,$ionicPopup,$ionicLoading,$rootScope,$ionicHistory,$ionicViewSwitcher,$cordovaNetwork) {
        $ionicPlatform.ready(function() {
            // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
            // for form inputs)
            if (window.cordova && window.cordova.plugins && window.cordova.plugins.Keyboard) {
                cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
                // cordova.plugins.Keyboard.disableScroll(false);
            }
            if (window.StatusBar) {
                StatusBar.styleDefault();
            }  

            //监听网络
            $rootScope.$on('$cordovaNetwork:online', function (event, networkState) {
                var onlineState = networkState;
                $ionicLoading.show({
                    template: '网络已恢复',
                    noBackdrop :true,
                    duration: 2500
                });
            })
            $rootScope.$on('$cordovaNetwork:offline', function (event, networkState) {
                var offlineState = networkState;
                $ionicLoading.show({
                    template: '网络异常，不能连接到服务器！',
                    noBackdrop :true,
                    duration: 2500
                });
            }) 

        });

另外，顺带附上一个ionic ngCordova 的参考文档，非常有用，在此记录一下：http://www.ionic-china.com/doc/ngCordova/
