Question

我正在尝试使用工厂服务在我的ionic / angular + phonegap应用程序项目中使用全局变量。

然而，添加一个简单的工厂服务，如下面的那个会以某种方式混淆应用程序＆amp;应用程序的所有屏幕都变成纯白色。

.factory('serviceName', function() {
    return {}
})

我有两个名为app.js＆amp;的js文件controller.js

app.js看起来像这样有更多的状态：

// Ionic Starter App
// angular.module is a global place for creating, registering and retrieving Angular modules
// 'starter' is the name of this angular module example (also set in a <body> attribute in index.html)
// the 2nd parameter is an array of 'requires'
// 'starter.controllers' is found in controllers.js
angular.module('starter', ['ionic', 'starter.controllers'])

//TRIED ADDING FACTORY HERE

.run(function($ionicPlatform) {
  $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.Keyboard) {
      cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
      cordova.plugins.Keyboard.disableScroll(true);

    }
    if (window.StatusBar) {
      // org.apache.cordova.statusbar required
      StatusBar.styleDefault();
    }
  });
})

.config(function($stateProvider, $urlRouterProvider) {
  $stateProvider
    .state('app', {
    url: '/app',
    abstract: true,
    templateUrl: 'templates/menu.html',
    controller: 'AppCtrl'
  });
$urlRouterProvider.otherwise('/app/playlists');
});

我的controller.js有点看起来像这样有更多的变量＆amp;功能：

angular.module('starter.controllers', [])


//ALSO TRIED ADDING FACTORY HERE

.controller('AppCtrl', function($scope, $ionicModal, $timeout,$http) {

  // With the new view caching in Ionic, Controllers are only called
  // when they are recreated or on app start, instead of every page change.
  // To listen for when this page is active (for example, to refresh data),
  // listen for the $ionicView.enter event:
  //$scope.$on('$ionicView.enter', function(e) {
  //});

  // Form data for the login modal
  $scope.loginData = {};
})


.controller('PlaylistsCtrl', function($scope) {
  $scope.playlists = [
    { title: 'Reggae', id: 1 },
    { title: 'Chill', id: 2 },
    { title: 'Dubstep', id: 3 },
    { title: 'Indie', id: 4 },
    { title: 'Rap', id: 5 },
    { title: 'Cowbell', id: 6 }
  ];
})

.controller('PlaylistCtrl', function($scope, $stateParams) {
})

我提到这个http://mcgivery.com/ionic-using-factories-and-web-services-for-dynamic-data/开始使用工厂。

我知道可以使用$ rootScope，但它有problems of global variables，所以请帮我使用工厂。另外，如果有人可以通过phonegap给我调试提示。我在android上使用phonegap开发应用程序，并在使用它时一直关注控制台。

您可以在应用中使用 factory ，如下所示：

.factory("serviceName", function() {
    var playlists = [{
        title: 'Reggae',
        id: 1
    }, {
        title: 'Chill',
        id: 2
    }, {
        title: 'Dubstep',
        id: 3
    }, {
        title: 'Indie',
        id: 4
    }, {
        title: 'Rap',
        id: 5
    }, {
        title: 'Cowbell',
        id: 6
    }];

    var _myVariableValue = 123;

    return {
        myPlayList: function() {
            return playlists;
        },
        getValue: function() {
            return _myVariableValue;
        }
    };
})

并拨打 controller

.controller('PlaylistsCtrl', function($scope, serviceName) { 
    $scope.playlists =  serviceName.myPlayList();
    $scope.myvariablevalue =  serviceName.getValue();    
})

如何使用Ionic / Angular JS和phonegap工厂？
