AngularJS

Question

我正在尝试根据给定的数组结构更改显示结果。我以为我可以用ng-switch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"}

事情是这样的。如果声明 'huesped' 职位，我需要一个场景。如果 stay.booking > 0，场景 B。如果没有声明停留，场景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>

我知道出事了。不知道代码中是否有某些细节，或者 ng-switch 是否无法执行我需要的操作。希望你能帮助我。

Answer 1

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

Be aware that the attribute values to match against cannot be expressions. They are interpreted as literal string values to match against. For example, ng-switch-when="someVal" will match against the string "someVal" not against the value of the expression $scope.someVal.

您的问题很容易通过 ng-if 解决。
