AngularJS：從工廠

Question

返回數據的「子集」我有這樣的工廠：

(function(){ 

    var requestsFactory = function(){ 

     var requests = [ 
      {id: 1, title: 'First Request', status: 'In Progress'}, 
      {id: 2, title: 'Second Request', status: 'Closed'}, 
      {id: 3, title: 'Third Request', status: 'Waiting'}, 
      {id: 4, title: 'Fourth Request', status: 'Closed'}, 
      {id: 5, title: 'Fifth Request', status, 'In Progress'} 
     ]; 

     var factory = {}; 

     factory.getAllRequests = function(){ return requests; }; 
     /* THIS IS NEW */ 
     factory.getOpenRequests = function(){ 
      var open_requests = filter(requests.status, function(status){ 
      return status !== 'Closed'; 
      }); 
      return open_requests; 
     }; 
     /* END NEW */ 

     return factory; 
}; // end requestsFactory 

     return factory; 
    }; 

    angular.module('appITI').factory('requestsFactory', requestsFactory); 
}()); 

而這個控制器：

(function(){ 

    var UsersController = function($scope, usersFactory, requestsFactory){ 
     $scope.current_user = []; 
     $scope.requests = []; 
     $scope.open_requests = []; // NEW 

     $scope.prefs = 'false'; 

     function init(){ 
      $scope.current_user = usersFactory.getCurrentUser(); 
      $scope.requests = requestsFactory.getAllRequests(); 
      $scope.open_requests = requestsFactory.getOpenRequests(); //NEW 
     } 

     init(); 

    }; // end UsersController 

    UsersController.$inject = ['$scope', 'usersFactory', 'requestsFactory']; 

    angular.module('appITI').controller('UsersController', UsersController); 

}()); 

我需要一個方法添加到廠裏讓我能調用這樣的事情在控制器：

$scope.open_requests = requestsFactory.requestsByStatus('In Progress'); 

我一直這樣學習AngularJs這個週末我似乎不能圖吸收輸出我敢打賭的是簡單的JavaScript。

新 我在模板中有這個，現在頁面是白色的和破碎的。

<tr class="landing_data_row" data-ng-repeat="request in open_requests | filter:techFilter | orderBy:sortBy:reverse">

向您的工廠添加新功能，並使用filter功能。

factory.getOpenRequests = function(){ 
    return requests.filter(function(el){ 
    return el.status !== 'Closed'; 
    }); 
};
