我实际上$rootScope在模块运行时提供了一个可用的模块，它可以从视图中完全访问，但我想在另一个控制器中访问该值，不幸的是我无法访问它。请提出一些方法。

  1. 我之前曾尝试通过服务使这些日期选择器弹出选项可用，但未能做到这一点，因为我不知道服务/工厂如何使用它们。更重要的是，我在视图中获得了更新的值，但我想要在我的控制器中获得相同的更新值，因此它可以分配给不同的范围变量。如果有人可以在服务中为我制作以下代码，那么至少我会明白并开始创建其他可注入服务。

angular.module("TestApp", ["ui.bootstrap"])
.run(['$rootScope', function ($rootScope) {

        $rootScope.clear = function () {
            $rootScope.Date1 = null;
            $rootScope.Date2 = null;
            $rootScope.Date1();
        };


        $rootScope.inlineOptions1 = {
            customClass: getDayClass,
            minDate: new Date(),
            //    showWeeks: true

        };

        $rootScope.inlineOptions2 = {
            customClass: getDayClass,
            minDate: new Date(),
            //    showWeeks: true
        };

        $rootScope.dateOptions1 = {
            //dateDisabled: disabled,
            formatYear: 'yyyy',
            maxDate: new Date(2050, 7, 22),
            minDate: new Date(),

            startingDay: 1
        };

        $rootScope.dateOptions2 = {
            //dateDisabled: disabled,
            formatYear: 'yyyy',
            maxDate: new Date(2050, 5, 22),
            minDate: new Date(),

            //minDate: new Date($$rootScope.changeMin()),
            startingDay: 1
        };


        $rootScope.toggleMin = function () {

            $rootScope.inlineOptions1.minDate = $rootScope.inlineOptions1.minDate ? null : new Date();
            $rootScope.dateOptions1.minDate = $rootScope.inlineOptions1.minDate;

            var min2 = new Date();

            $rootScope.$watch('Date1', function () {
                min2 = $rootScope.Date1;
                $rootScope.dateOptions2.minDate = min2;

                if ($rootScope.Date1 > $rootScope.Date2) {
                  
                    $rootScope.Date2 = $rootScope.Date1;
                  
                }
                

            }, true);


            $rootScope.$watch('Date2', function () {

                if ($rootScope.Date2 < $rootScope.Date1) {
                  
                    $rootScope.Date1 = $rootScope.Date2;
                  
                }
                

            }, true);
        };

        $rootScope.toggleMin();
        $rootScope.open1 = function () {
            $rootScope.popup1.opened = true;
        };

        $rootScope.open2 = function () {
            $rootScope.popup2.opened = true;
        };

        $rootScope.popup1 = {
            opened: false

        };

        $rootScope.popup2 = {
            opened: false
        };

        $rootScope.setDate = function (year, month, day) {
            $rootScope.Date1 = new Date(year, month, day);
            $rootScope.Date2 = new Date(year, month, day);

        };

        $rootScope.formats = ['dd-MMMM-yyyy', 'yyyy/MM/dd', 'dd-MM-yyyy', 'shortDate'];
        $rootScope.format = $rootScope.formats[2];
        $rootScope.altInputFormats = ['M!/d!/yyyy'];

        function getDayClass(data) {
            var date = data.date,
              mode = data.mode;
            if (mode === 'day') {
                var dayToCheck = new Date(date).setHours(0, 0, 0, 0);

                for (var i = 0; i < $rootScope.events.length; i++) {
                    var currentDay = new Date($rootScope.events[i].date).setHours(0, 0, 0, 0);

                    if (dayToCheck === currentDay) {
                        return $rootScope.events[i].status;
                    }
                }
            }

            return '';
        }

    }]);

使用服务非常简单。看看下面的例子。

var testModule = angular.module('testmodule', []);

testModule
   .controller('QuestionsStatusController1',['$rootScope', '$scope', 'myservice', function ($rootScope, $scope, myservice) {
       $scope.myservice = myservice;
   }]);

testModule
   .controller('QuestionsStatusController2',['$rootScope', '$scope', 'myservice',function ($rootScope, $scope, myservice) {
       $scope.myservice = myservice;
   }]);

testModule
    .service('myservice', function() {
       this.xxx = "yyy";
    });
