AngularJS-ngSwitch具有多维数组

Question

我正试图根据给定的数组结构更改显示结果。我以为我可以用ng开关做到这一点，但找不到解决它的方法。

我有这个json:

0: {size: 1, room: 1, id: 1, name: "",…}
huesped: {id: 1, name: "Pablo", lastname: "Bertran", passport: "33025915N", birth: "1987-04-14", country: 10,…}
id: 1
name: ""
room: 1
size: 1
stay: {id: 1, booking: 0, room: 1, bed: 1, guest: 1, indate: "2015-11-02", outdate: "2015-12-02", hotel: 1,…}
1: {size: 1, room: 1, id: 2, name: ""}
2: {size: 1, room: 1, id: 3, name: ""}
3: {size: 1, room: 1, id: 4, name: ""}
4: {size: 1, room: 1, id: 5, name: ""}
5: {size: 1, room: 1, id: 6, name: ""}
6: {size: 2, room: 2, id: 7, name: "1"}

问题是，如果声明了"huesped"位置，我需要一个场景。如果住宿预订>0，场景B。如果没有宣布停留，情况C.

我尝试过这个代码：（假设json在$scope.beds中）

                    <div ng-switch on="bed">
                        <div ng-switch-when="bed.huesped">
                            <div class="md-list-item-text" ng-click="accion(bed.guest.id, 2)" style="background-color: rgba(0,0,255,0.7);">
                                <h3>Cama - {{::bed.id}}</h3>
                                <h4>{{ bed.huesped.name }} {{ bed.huesped.lastname }}</h4>
                            </div>
                        </div>
                        <div ng-switch-when="bed.stay.booking">
                            <div class="md-list-item-text" ng-click="accion(bed.booking.id, 3)" style="background-color: rgba(255,0,0,0.7);">
                                <h3>Cama - {{::bed.id}}</h3>
                                <h4>{{ bed.booking.name }}</h4>
                            </div>
                        </div>
                        <div ng-switch-default>
                            <div class="md-list-item-text" ng-click="accion(bed.id, 1)" style="background-color: rgba(0,255,0,0.7);">
                                <h3>Cama - {{::bed.id}}</h3>
                                <h4>{{::bed.size}} Plaza(s)</h4>
                            </div>
                        </div>
                    </div>

我知道出了问题。不知道代码中是否有一些细节，或者ng switch是否无法完成我需要的操作。希望你能帮助我。

https://docs.angularjs.org/api/ng/directive/ngSwitch说：

请注意，要匹配的属性值不能是表达式。它们被解释为要匹配的文字字符串值。例如，当="someVal"时，ng开关将与字符串"some瓦尔"匹配，而不是与表达式$scope.someVal.的值匹配

使用ng-if可以轻松解决您的问题。
