Question

我正在建造一个带有棱角和纤细框架的水疗中心。根据下面提到的代码，我想要做的是，登录页面控制器将成功提交user / psw后将数据传递给登陆页面控制器。当我将工厂放在http呼叫/登录功能之外时，它会获取数据，但在登陆页面工厂不提供数据。当我把它放在里面停止工作。请帮帮我......

此工厂用于跨控制器共享数据

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网站用户重定向和门户网站呈现

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';
        });
    }
}]);

此控制器用于着陆页路由

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);

}]);

Answer 1

当您执行sharedFactory.add($scope.Userdata); $scope.Userdata时，landingController是另一个dataToBeShared未观看的对象。通过在sharedFactory.add函数中重新分配landingController，您将丢失对原始对象的引用，因此无法再从代码中访问它。

要使sharedFactory.add看到更改，您需要重新实现sharedFactory.dataTobeShared功能以推送lapply(1:length(markers), function(i) { newNames[i] <<- input[[paste0("marker", i)]] }) printf(newNames) 数组中的值或使用某些基于事件的通知，而不是$手表。

以下jsfiddle来说明我的话。

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);

}]);

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.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中从工厂获取值。

工厂无法将数据传送到另一个控制器
