Question

我试图根据给定的数组结构更改显示结果。我认为我可以用ng-switch这样做，但无法找到解决问题的方法。

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"}

事情是这样的。如果＆＃39; huesped＆＃39;位置被宣布，我需要一个场景。如果stay.booking＆gt; 0，方案B. 如果没有宣布停留，则方案C。

我试过这段代码：（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>

我知道一些错误。不知道代码中是否有一些细节，或者ng-switch是否能够满足我的需要。希望你能帮帮我。

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，ng-switch-when =“someVal”将匹配字符串“someVal”，而不是表达式$ scope.someVal的值。

使用ng-if可以轻松解决您的问题。
