Question

我正在尝试基于this article在AngularJS中创建一个工厂。但我得到一个错误说＆＃34; dataFactory＆＃34;在我的控制器中未定义。我的代码如下所示：

MyApp.factory('dataFactory', ['$http', function($http)
    {
        var urlBase='/someurl/roles/';
        var dataFactory={};

        dataFactory.getRoles=function()
        {
            return $http.get(urlBase+'getlist');
        };

        dataFactory.addRole=function(roleName, roleCss)
        {
            return $http.get(urlBase+'add&name='+roleName+'&css='+roleCss);
        };

        dataFactory.updateRole=function(role)
        {
          return $http.get(urlBase+edit&id='+role.id+'&name='+role.name+'&css='+role.css');
        };

        dataFactory.deleteRole=function(role)
        {
            return $http.get(urlBase+'remove&id='+role.id);
        };

        return dataFactory;
    }]);

MyApp.controller('RoleCtrl',['$scope','$http','dataFactory', function($scope,$http,$rootScope,dataFactory) {
     dataFactory.getRoles().then(function(res){
        $scope.roles = res.data.result;   
      });
 }]);

我做错了什么？

你错过了'$ rootScope'的字符串版本

所以而不是

MyApp.controller('RoleCtrl',['$scope','$http','dataFactory', function($scope,$http,$rootScope,dataFactory) {

使用（注意添加'$rootScope'）：

MyApp.controller('RoleCtrl',['$scope','$http','$rootScope','dataFactory', function($scope,$http,$rootScope,dataFactory) {

由于你的参数不对齐，

dataFactory进入$ rootscope。然后没有什么可以发送到dataFactory。因此你的错误。

工厂在angularjs中未定义
