Angularjs 工厂无法将数据传送到另一个控制器

我正在建造一个有棱角和纤细框架的水疗中心。根据下面提到的代码，我试图做的是，登录页面控制器将在成功提交用户/psw后将数据传递给登录页面控制器。当我将工厂放在http调用/登录函数之外时，它会获取数据，但在登录页上工厂不会传递数据。当我把它放进去的时候，它就停止工作了。请帮帮我

此工厂用于在控制器之间共享数据

appDls.factory('sharedFactory', function () {
    var dataTobeShared = {};
    var interface = {};
    interface.add = function (d) {
        dataTobeShared = d;
    }
    interface.put = function () {
        return dataTobeShared;
    }
    return interface;
});

此控制器用于主门户用户重定向和门户呈现

appDls.controller('DlsappController', ['$scope', '$state', 'multipartForm', 'sharedFactory', '$window', function ($scope, $state, multipartForm, sharedFactory, $window) {
    $scope.Userdata = [];
    $scope.login = function () {
        var url = "../scripts/routes.php/authen";
        multipartForm.post(url, $scope.login).then(function (d) {
            $scope.Userdata.push(d.data[0]);
            sharedFactory.add($scope.Userdata);
            $window.location.href = '../portal/landing.php';
        });
    }
}]);

appDls.controller('landingController', ['$scope', '$state', 'multipartForm', 'sharedFactory', function ($scope, $state, multipartForm, sharedFactory) {
    $scope.UserInfo = sharedFactory.put();
    $scope.$watch('UserInfo', function (newValue, oldValue) {
        /*here we can use the user data from login page*/
        if (newValue.length == 1) {
            alert(newValue[0].fullname);
            $state.go(newValue[0].proftype);
        } else {
            alert("user not logged in successfully!");
            $state.go('default');
        }

    }, true);

}]);

此控制器用于登录页路由

appDls.controller('DlsappController', ['$scope', '$state', 'multipartForm', 'sharedFactory', '$window', function ($scope, $state, multipartForm, sharedFactory, $window) {
    $scope.Userdata = [];
    $scope.login = function () {
        var url = "../scripts/routes.php/authen";
        multipartForm.post(url, $scope.login).then(function (d) {
            $scope.Userdata.push(d.data[0]);
            sharedFactory.add($scope.Userdata);
            $window.location.href = '../portal/landing.php';
        });
    }
}]);

appDls.controller('landingController', ['$scope', '$state', 'multipartForm', 'sharedFactory', function ($scope, $state, multipartForm, sharedFactory) {
    $scope.UserInfo = sharedFactory.put();
    $scope.$watch('UserInfo', function (newValue, oldValue) {
        /*here we can use the user data from login page*/
        if (newValue.length == 1) {
            alert(newValue[0].fullname);
            $state.go(newValue[0].proftype);
        } else {
            alert("user not logged in successfully!");
            $state.go('default');
        }

    }, true);

}]);

当您执行

sharedFactory.add（$scope.Userdata）时

您的

$scope.Userdata

是另一个对象，它不被

landingController

监视。通过在

sharedFactory.add

函数中重新分配

dataToBeShared

，您将丢失对原始对象的引用，因此无法再从代码访问该对象

要使

landingController

查看您需要的更改，或者重新实现

sharedFactory。添加
函数以推送
sharedFactory.dataTobeShared
数组中的值，或者使用一些基于事件的通知，而不是$watch

下面是我的示例。
观察者需要在每个摘要周期从工厂获取值，并更新$scope变量

appDls.factory('sharedFactory', function () {
    var dataTobeShared = {};
return 
  {
    add: function (d) {
        dataTobeShared = d;
    }
    put: function () {
        return dataTobeShared;
    }
  }

});


appDls.controller('DlsappController', ['$scope', '$state', 'multipartForm', 'sharedFactory', '$window', function ($scope, $state, multipartForm, sharedFactory, $window) {
    $scope.Userdata = [];
    $scope.$watch('login',function () {
        var url = "../scripts/routes.php/authen";
        multipartForm.post(url, $scope.login).then(function (d) {
            $scope.Userdata.push(d.data[0]);
            sharedFactory.add($scope.Userdata);
            $window.location.href = '../portal/landing.php';
        });
    }
}]);


appDls.controller('landingController', ['$scope', '$state', 'multipartForm', 'sharedFactory', function ($scope, $state, multipartForm, sharedFactory) {
    $scope.UserInfo = sharedFactory.put();
    $scope.$watch('UserInfo', function (newValue, oldValue) {
        /*here we can use the user data from login page*/
        if (newValue.length == 1) {
            alert(newValue[0].fullname);
            $state.go(newValue[0].proftype);
        } else {
            alert("user not logged in successfully!");
            $state.go('default');
        }

    }, true);

}]);

appDls.controller('landingController', ['$scope', '$state', 'multipartForm', 'sharedFactory', function ($scope, $state, multipartForm, sharedFactory) {
    //$scope.UserInfo = sharedFactory.put();
    //$scope.$watch('UserInfo', function (newValue, oldValue) {
    $scope.$watch(sharedFactory.put, function (newValue, oldValue) {
        //UPDATE scope variable
        $scope.UserInfo = newValue;
           /*here we can use the user data from login page*/
        if (newValue.length == 1) {
            alert(newValue[0].fullname);
            $state.go(newValue[0].proftype);
        } else {
            alert("user not logged in successfully!");
            $state.go('default');
        }

    }, true);

}]);

原始代码仅在控制器初始化时设置范围变量一次。它需要在每个摘要周期从工厂获取值。
请编辑您的帖子以停止叫喊-在任何地方使用这样的大写都是不礼貌的。谢谢您的评论…我已经编辑了问题。。。。
