        }

        $scope.childmethod = function() {
            // Here i want to call parentmethod of One controller
        }
    }
]);

推荐答案

控制器之间的通信通过 $ emit + $ on / $ broadcast + $

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

因此，在你的情况下，你想在ControllerTwo里面调用ControllerOne的方法，正确的方法是这是：

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", {});
        }
    }
]);

而 $ rootScope。$ emit ，您可以发送任何数据作为第二个参数。

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