Angular Typeerror无法读取未定义的属性get

Question

我正在阅读其他stackoverflow文章和更改代码，但我似乎无法理解这个

angular.module('app')
          .controller('DefaultCtrl', ['$scope', function ($scope) { }])

工厂是问题

.factory('autoCompleteDataService', [function ($scope, $http) {
    return {
        getSource: function($scope) {
            $http.get("GetPersonInfoFromRegister/T")
                .success(function(data) {
                    $scope.countries = data;
                });
        }

这个指令很好，我试图修改工厂从静态返回的ajax调用返回数据

.directive('autoComplete', function (autoCompleteDataService) {
return {
    restrict: 'A',
    link: function (scope, elem, attr, ctrl) {
        // elem is a jquery lite object if jquery is not present,
        // but with jquery and jquery ui, it will be a full jquery object.
        debugger;
        elem.autocomplete({
            source: autoCompleteDataService.getSource(), //from your service
            minLength: 1
        });
    }
};
});

    }

}])

当我使用示例并返回

时工厂正在工作

return ["john", "bill", "charlie", "robert", "alban", "oscar", "marie", "celine", "brad", "drew", "rebecca", "michel", "francis", "jean", "paul", "pierre", "nicolas", "alfred", "gerard", "louis", "albert", "edouard", "benoit", "guillaume", "nicolas", "joseph"];
