如何获取 firebaseArray 对象的键 [英] How to get the key of a firebaseArray object

问题描述

我正在尝试获取返回的 firebaseArray 记录的密钥，但我没有运气.

I am trying to get the key for a returned firebaseArray record but am having no luck.

我有一个服务，它运行以下命令来返回一个商店

I have aservice that runs the following to return a store

getStore: function(uid, id){
    var ref = firebase.database().ref('u/'+uid+'/stores/'+id+'/i/');
     // to take an action after the data loads, use the $loaded() promise
     return $firebaseArray(ref);
}

我使用以下方法通过调用服务来获取每条记录

I use the following to get eeach record by calling the service

for(var i = 0; i < $scope.storesList.length; i++){
    var storeInfo = Stores.getStore($rootScope.user['uid'], $scope.storesList[i]['$id']);
    storeInfo.$loaded().then(function(data){
            $scope.stores.push(data);
            console.log($scope.stores);
    });
}

在我的 html 中，我可以访问数组中的各种属性

In my html I can access various properties within the array

<li ng-repeat="store in stores">
      <span class="store-address">{{store.$getRecord('name').$value}}</span>
      <span class="store-address">{{store.$getRecord('address1').$value}}</span>
</li>

但我似乎无法从 ng-repeat 中获取每个商店记录的 id

But I cannot seem to get the id for each store record from within the ng-repeat

推荐答案

要获取 id，只需调用项目上的 $id.

To get the id simply call the $id on the item.

<li ng-repeat="store in stores">
      <span class="store-address">{{store.$getRecord('name').$value}}</span>
      <span class="store-address">{{store.$getRecord('address1').$value}}</span>
      <span class="store-address">{{store.$id}}</span>
</li>
