推荐答案

您不能调用从控制器内的控制器的方法。您将需要提取出来的方法，创建一个服务并调用它。这也将彼此分离的code，并使其更容易测试

You can't call a method from a controller within a controller. You will need to extract the method out, create a service and call it. This will also decouple the code from each other and make it more testable

(function() {
    angular.module('app', [])
        .service('svc', function() {
            var svc = {};

            svc.method = function() {
                alert(1);
            }

            return svc;
        })
        .controller('ctrl', [
            '$scope', 'svc', function($scope, svc) {
                svc.method();
            }
        ]);
})();
