输入无法读取| Angularfire + Firebase

所以,我在一个有角度的重复项目中有一个选择输入。我想用一个按钮为一个人分配房间。除了维持一个人选择了房间外,它还会显示它已在选择输入中分配。

这是我的Firebase数据:

{
  "-JLtuRmYiTDLTnZPj" : {
    "last_name" : "NameOne",
    "person_id" : 1,
    "is_in" : false
  },
  "-JLtuRBlyWhHV28zd" : {
    "last_name" : "NameTwo",
    "person_id" : 2,
    "is_in" : false
  },
  "-JLtuQxlMn25APuKT" : {
    "last_name" : "NameThree",
    "person_id" : 3,
    "is_in" : false
  }
}

这是我的代码:

<table>
    <tbody>
      <tr ng-repeat="(name, person) in people | orderBy: 'doctor_id'" ng-model="person">
        <td>{{person.person_id}}</td>
        <td>{{person.last_name}}</td>
        <td><strong>{{person.is_in}}</strong></td>
        <td>Assign Rooms: <select multiple class="form-control" ng-model="person.room_id" ng-options="r.room_id as r.name for (key, r) in rooms"></select></td>
        <td><button type="button" href="" class="btn btn-primary" ng-click="assignRooms(name)">Assign Rooms</button></td>
      </tr>
    </tbody>
</table>

最后我的JS:

angular.module('app', ['ngRoute', 'firebase']);

$scope.people = $firebase(new Firebase("https://<FB-NAME>.firebaseio.com/dev/0/people"));
$scope.rooms = $firebase(new Firebase("https://<FB-NAME>.firebaseio.com/dev/0/rooms"));

//Assigns Rooms to each doctor.
$scope.assignRooms = function(name) {

    $scope.people.$child(name).$update({
        "room_id": $scope.person.room_id,
        "is_in": true
        });     
}

正确调用该应用。当我使用Angular JS Batarang时,我可以看到范围。当我单击Assign Rooms按钮时,我收到错误:

无法阅读属性&#39; room_id&#39;未定义的

来自:$ scope.person.room_id。

我确信这是我想念的事情。但是非常感谢任何帮助。

谢谢!

您需要使用person。您无法访问函数中的ng-repeat范围。

<td>
    <button type="button" 
            href="" 
            class="btn btn-primary" 
            ng-click="assignRooms(name,person)">Assign Rooms</button>
</td>

$scope.assignRooms = function(name, person) {$scope.assignRooms = function(name) {

    $scope.people.$child(name).$update({
    "room_id": person.room_id,
    "is_in": true
    });     
}
