I need to call function in another controller in angular js.How it is possible way please help me thanks in advance

代码:

    function($scope) {
        $scope.parentmethod = function() {
            // task
        }

        $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 + $on 方法.

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

因此，在您的情况下，您想在控制器二"中调用控制器一"的方法，正确的方法是:

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", {});
        }
    }
]);

在调用 $rootScope.$emit 时，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.
