How to call controller's method in module (AngularJS)

Question

How to get some specific controller's $scope variable?

    myApp.factory('Comment', ['$http', function ($http) {
        var comment = {};

        comment.add = function (shortName, taskNum, message) {
            // how to call controller's method
            // the following line dosen't work
            myApp.ListPanelController.showTaskDetail(shortName, taskNum);

        }

        return comment;
    }



    myApp.controller('ListPanelController', ['$scope', 'Comment',
        function ($scope, Comment) {
            $scope.showTaskDetail = function (shortName, taskNum) {
                Tasks.get(shortName, taskNum).success(function (data) {
                    // do something
                });
            }
        }]
    );

You need to explain your scenario. Services are shared code\functionality and controllers are view specific. There should be no reason to call into a controller functionality from service. — Chandermani

You can't inject $scope into services, there is nothing like a singleton $scope.

But you can pass variables to your service or use $rootScope if you interesting to use $apply.

 myApp.factory('Comment', ['$http', '$rootScope', function ($rootScope,$http){/*..*/}

But I would return promise and call showTaskDetail into controller.

myApp.factory('Comment', ['$http', '$rootScope', function ($rootScope,$http){/*..*/}
