How to call a function from another controller in angularjs? [duplicate]

Question

I need to call a function in another controller in AngularJS. How can I do this?

Code:

app.controller('One', ['$scope',     function($scope) {         $scope.parentmethod = function() {             // task         }     } ]);  app.controller('two', ['$scope',     function($scope) {         $scope.childmethod = function() {             // Here i want to call parentmethod of One controller         }     } ]);

Communication between controllers is done though $emit + $on / $broadcast + $on methods.

So in your case you want to call a method of Controller "One" inside Controller "Two", the correct way to do this is:

app.controller('One', ['$scope', '$rootScope'     function($scope) {         $rootScope.$on("CallParentMethod", function(){            $scope.parentmethod();         });          $scope.parentmethod = function() {             // task         }     } ]); app.controller('two', ['$scope', '$rootScope'     function($scope) {         $scope.childmethod = function() {             $rootScope.$emit("CallParentMethod", {});         }     } ]); 

While $rootScope.$emit is called, you can send any data as second parameter.
