如何在另一个函数之后运行第二个函数，后者等待从前者返回变量

Question

是否有可能或者有更好的方法在$ scope.found返回后，在ng-click事件启动导引头功能的情况下运行执行函数。

 $scope.adder = {
            seeker:function(){
                $scope.found = null;
                $scope.found = $scope.services.find(function(service){
                    return service;
                });
                Loader.showLoading('Added to cart');
                return $scope.found;
            },
            execute:function($scope,found){
                if($scope.found != null){
                    $scope.cart.addItem(found.title, found.pricing, found.qty);
                    Loader.hideLoading();
                }
            }
        }
