javascript - 从 Angular Factory 调用 JSON 文件不起作用

Question

我是 AngularJS 的新手。我试图从工厂函数调用 json 文件，但它显示我的 varcustomers = []; 数组未更新。请帮忙。

下面是我的代码。

var demoApp = angular.module("myApp", []);

demoApp.factory('simpleFactory', ['$http', function($http){

    return {

        getCustomer: function(){
            var customers = [];
            return $http.get("http://www.w3schools.com/website/Customers_JSON.php")
            .success(
                function(data){

                    customers = data;
                },
                function(error){
                    console.log(error);
                });
            console.log(customers)
        }

    }

}]);

demoApp.controller("emplyCtrl", function($scope, simpleFactory){
    $scope.customers = simpleFactory.getCustomer();
});

尝试这样的事情:

demoApp.factory('simpleFactory', ['$http', function($http){

    return {

        getCustomer: function(){

            return $http.get("json/customers.json").then(
                function(response){
                    var customers = [];
                    customers = response.data;
                },
                function(error){
                    console.log(error);
                });

        }

    }
}]);
