angular 多个 $mdDialog

Question

我使用模式选项卡，我有通知弹出窗口 window 当用户登录我的应用程序时，它总是显示给用户。它包含用户离线时发生的所有事件。问题是当我单击列表中的任何对象时，它会关闭我的弹出窗口 window 并显示新的模式选项卡。

我想实现这个功能。当用户登录时，将向用户显示通知弹出窗口 window，如果他单击任何对象，它将打开另一个 window 而不会关闭我的通知弹出窗口 window（新事件).我想要下面我制作的图片上的类似内容。

我检查了 angular material 文档，但根本没有演示，甚至没有很好地解释如何使用 multiple: true 选项，我不知道如何让它像我想要的那样工作。

这是我用于显示通知弹出窗口的代码 window。

//show new notifications when user log in
    NotificationService.getUnreadedNotifications(function (data) {
        //initialization
        $scope.notification = [];
        $scope.OverAllCount = 0;
        $scope.messageNotification = [];
        $scope.OverAllMessageCount = 0;

        if (data.ProjectNotifications != null) {
            angular.forEach(data.ProjectNotifications, function (key, value) {
                $scope.notification.push(key);
                $scope.OverAllCount = $scope.OverAllCount + 1;
            });
        }

        if (data.TasksNotifications != null) {
            angular.forEach(data.TasksNotifications, function (key, value) {
                $scope.notification.push(key);
                $scope.OverAllCount = $scope.OverAllCount + 1;
            });
        }

        if (data.MessageNotifications != null) {
            angular.forEach(data.MessageNotifications, function (key, value) {
                $scope.OverAllMessageCount = $scope.OverAllMessageCount + 1;
                $scope.messageNotification.push(key);
            });
        }

        popUpNotification();

        $scope.hide = function () {
            $mdDialog.hide();
        };

        $scope.cancel = function () {
            $mdDialog.cancel();
        };

        $scope.answer = function (answer) {
            $mdDialog.hide(answer);
        };

        //mark notifications as readed when user click on notification
        function popUpNotification() {
            $mdDialog.show({
                controller: NotificationController,
                templateUrl: 'app/components/templates/PopUpNotification.html',
                parent: angular.element(document.body),
                //targetEvent: ev,
                clickOutsideToClose: true,
                fullscreen: false,
                scope: $scope,
                multiple:true,
                preserveScope: true,
                onComplete: function () {
                    $scope.notificationPopUp = $scope.notification;
                }
            })
            .then(function () {

            }, function () {
                //fail
            });
        }
    });

这是用于显示用户在新的覆盖模式选项卡中单击的对象的详细信息的代码

        //mark notifications as readed when user click on notification
    $scope.popUpDetail = function (notification, index, ev) {
        $mdDialog.show({
            controller: NotificationController,
            templateUrl: 'app/components/templates/TaskDetailsDialog.html',
            parent: angular.element(document.body),
            targetEvent: ev,
            clickOutsideToClose: true,
            fullscreen: false,
            scope: $scope,
            multiple: true,
            preserveScope: true,
            onComplete: function () {
                //was readed => update database
                NotificationResourceService.update({ id: notification.Id }, notification);
                $scope.OverAllCount -= 1;
                $scope.notification.splice(index, 1);

                TaskService.get({ id: notification.EntityId })
                    .$promise.then(function (task) {
                        $scope.task = task;
                    });
            }
        })
        .then(function () {

        }, function () {
            //fail
        });
    }

不知何故，我找到了解决问题的方法。它可能会在将来帮助某人。

工作代码：

 function popUpNotification() {
            $mdDialog.show({
                templateUrl: 'app/components/templates/PopUpNotification.html',
                clickOutsideToClose: true,
                bindToController: true,
                scope: $scope,  
                preserveScope: true,
                controller: function ($scope, $mdDialog) {
                    $scope.notificationPopUp = $scope.notification;
                    $scope.popUpDetail = function (notification, index, ev) {
                        $mdDialog.show({
                            controller: function ($mdDialog) {
                                this.click = function () {
                                    $mdDialog.hide();
                                }
                            },
                            targetEvent: ev,
                            clickOutsideToClose: true,
                            preserveScope: true,
                            autoWrap: true,
                            skipHide: true,
                            scope: $scope,
                            preserveScope: true,
                            templateUrl: 'app/components/templates/TaskDetailsDialog.html',
                            onComplete: function () {
                                TaskService.get({ id: notification.EntityId })
                                    .$promise.then(function (task) {
                                        $scope.task = task;
                                    });
                            }
                        })
                    }
                },
                autoWrap: false,
            })
        }
        });

添加'multiple: true'作为参数：

// From plain options
$mdDialog.show({
  multiple: true
});

// From a dialog preset
$mdDialog.show(
  $mdDialog
    .alert()
    .multiple(true)
);

Answer 3

关键是使用 skipHide: true 作为我们传递给 $mdDialog.show() 的对象的参数。我在没有 multiple: true 的情况下尝试过，它仍然有效。此参数必须传递 到第二个 （或第 n 个）对话框中。所以它看起来像这样：

// second dialog 
$mdDialog.show({
  // some fields
  skipHide: true,
  //some fields
});
