Question

我已经创建了angularJs工厂服务来处理REST调用。服务工作正常。我有一些情况需要将值设置为$ scope.variable并在资源服务外部访问它们。但我得到了未定义。我将它们包裹在angularJs $q里面，但似乎我犯了一些错误。请帮助我解决这个问题。

AngularJs Factory

myApp.factory('MyService',function($resource) {

    return{
       GetMYData:$resource(my rest service URL, {});
      }

    });

在控制器中

$scope.myMap={};
$scope.promises=[];
$scope.myData = MyService.GetMYData.query();
            $scope.myData.$promise.then(function (result) {

            result.forEach(function(e, i) {
             //Do something
              var deferred = $q.defer();
              $scope.myMap[e.key]=e; //Put elements into map and i tried to access map from outside service by giving key

              deferred.resolve(result);
              $scope.promises.push(deferred.promise);
              $scope.myMap[$location.search()['dataID']] //This display the actual value
            })
    ...
}

如果URL中存在URL参数，我会执行以下操作。

if($location.search()['dataID']){

   $q.all($scope.promises).then(
   function(data) {
          console.log($scope.myMap[$location.search()['dataID']]) // throws      undefined
    },function(response) {
         //Handle if promises are rejected
        })
}

请告诉我如何从服务外部访问angularJs资源服务设置的地图值。

我将尝试做的是：

     myApp.factory('MyService',function($resource) {




 var _resource = $resource(my rest service URL, {},{
             query:{method:"GET",IsArray:true}
       })


            return{
               GetMYData:function(){
                       return _resource.query();
                      }
              }

            });

然后：

$scope.myMap={};
$scope.promises=[];
 MyService.GetMYData.$promise.then(function (result) {

            result.forEach(function(e, i) {
             //Do something

              $scope.myMap[e.key]=e; //Put elements into map and i tried to access map from outside service by giving key



              $scope.myMap[$location.search()['dataID']] //This display the actual value
            })
    ...
}

然后只访问您的

if($location.search()['dataID']){

  console.log($scope.myMap[$location.search()['dataID']]) );

}

范围变量值在angularjs中的资源服务之外未定义
