如何从角度调用app.js中的控制器方法

Question

我想调用app.js文件中的控制器方法[getFacility（）]。 但是当我用下面的代码段，我得到了错误，如

Error: [$injector:unpr] Unknown provider:

这里我控制器文件和服务文件

app.js

... 
...  
.state('facilityHome.editFacility', 
{ 
    url: '/editFacility/:facilityId', 
    templateUrl: '/views/facility/newFacility.html', 
    controller: 
     function($scope, $stateParams, facilityController) { 
       facilityController.getFacility($stateParams.facilityId); 
     } 
} 

.... 
... 

facilityControlelr.js

app.controller('facilityController', 
['$scope', '$rootScope','$location','$filter', 'facilityService', 
    function ($scope, $rootScope,$location,$filter, facilityService){ 

     /* Assign Object */ 
     var facilityScope = this; 

     /* Initialize DTO Object */ 
     facilityScope.facilityDTO={ 
      id:null, 
      version:null, 
      facilityName:"", 
      description:"" 
     }; 


     /* Initialize Object Array */ 
     facilityScope.facilityList = []; 


     facilityScope.getFacility=function(id){ 
      facilityService.fetchFacility(id) 
       .then(
       function(successRespond) { 
        $scope.facilityDTO = successRespond; 
       }, 
       function(errResponse){ 
        console.error('Error while fetching'); 
        console.error(errResponse); 
       } 
      ); 

     }; 

    } 
]); 

这里我得到了我的控制台。

Answer 1

为了注射控制器到另一个控制器，使用$controller服务。

.state('facilityHome.editFacility', 
{ 
    url: '/editFacility/:facilityId', 
    templateUrl: '/views/facility/newFacility.html', 
    controller: 
     function($scope, $stateParams, $controller) { 
      var facCtrl = $controller("facilityController", {'$scope': $scope}); 
      facCtrl.getFacility($stateParams.facilityId); 
     } 
} 

因为facilityController manipuates $scope，$scope需要被注入的本地。请参阅AngularJS $controller Service API Reference。

Answer 2

您不能在另一个控制器中注入控制器。你需要一个工厂/服务。

看到一些文档：https://docs.angularjs.org/guide/services
