AngularJS工厂中可以有多个功能吗？

这样的一个例子是： 演示链接

angular.module('services', []).factory('factoryName', ["$filter",  function($filter) {    var method1Logic = function(args) {      //pre    };    var method2Logic = function(args) {     //pre    };    return {      method1: method1Logic,      method2: method1Logic    };  }]).controller('MainController', ["$scope", "$rootScope", "$filter", "factoryName", function ($scope, $rootScope, $filter,factoryName) {     $scope.testMethod1 = function(arg){       $scope.val1 = factoryName.method1(arg);     };     $scope.testMethod2 = function(arg){       $scope.val2 = factoryName.method2(arg);     };}]);

甚至有这样一个更好的版本固执己见版

function AnotherService () {  var AnotherService = {};  AnotherService.somevalue = '';  AnotherService.someMethod = function () {  };  return AnotherService;}angular  .module('app')  .factory('AnotherService', AnotherService);
