如何获得一个firebaseArray对象的关键 [英] How to get the key of a firebaseArray object

问题描述

我试图获取返回的firebaseArray记录的关键字，但没有运气。

我有一个服务运行以下内容来返回一个商店

  getStore：function（uid，id）{
 var ref = firebase.database（）。ref（'u /'+ UID + '/商店/' + ID + '/ I /'）; 
 //在数据加载后采取行动，使用$ loaded（）promise 
 return $ firebaseArray（ref）; 
 
 $ / code> 

我通过调用服务来获取eeach记录

  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）; 
 }）; 
 
 
 
 $ b $ p 
 $ b 
在我的html中我可以访问数组中的各种属性
 < 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> 
  
但是我似乎无法从ng-repeat中得到每个商店记录的id 
解决方案
获取id只需调用项目上的$ id即可。  
 
 
 < 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>

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

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);
}
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);
    });
}
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>
But I cannot seem to get the id for each store record from within the ng-repeat
解决方案
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>
