Question

我想使用加载的firebaseArray从ng-repeat中获取所选值，检索profile.name

的值

上传.json

profile: {
  name: 'default',
  description: 'default',
  permissions: {
    regUser: false,
    regProfile: false,
    regCustomer: false
  }
}

html的

<select class="form-control">
                <option ng-repeat="profile in vm.profiles" ng-model="vm.firebaseUser.profile">{{profile.name}}</option>
            </select>

的.js

vm.createApplicationUser = function() {
            var profilesRef = firebase.database().ref('application/profiles/name/');
            vm.profiles = $firebaseArray(profilesRef);
            var usersRef = firebase.database().ref('application/users/').push().set({
                displayName: vm.firebaseUser.displayName,
                email: vm.firebaseUser.email,
                role: vm.firebaseUser.role,
                profile: vm.firebaseUser.profile
            });
        };

错误

Answer 1

ng-model应该在<select>标记中，而不在<option>。

如何使用firebaseArray从ng-repeat获取子属性值？
