I want to update an item in my application so I need an id that Firebase creates:
我想更新应用中的项目，因此我需要Firebase创建的ID：
https://db.firebaseio.com/userid/books/-L6_e2KsseGzwM8a0YUv
https://db.firebaseio.com/userid/books/-L6_e2KsseGzwM8a0YUv
The problem is that Firebase returns an object of objects, so I returned Object.values(data) and now I don't have that id which I could maybe access if Firebase returns classic array..
问题是Firebase返回一个对象对象，所以我返回了Object.values（数据），现在我没有那个我可以访问的id，如果Firebase返回经典数组的话。

you will get the key of the object by object.key. and for value you can do object.val() For multiple object you can try Object.keys() and Object.values() Is this you wanted? I can be more specific if you can post the block of code.
您将通过object.key获取对象的键。对于值，您可以执行object.val（）对于多个对象，您可以尝试Object.keys（）和Object.values（）这是您想要的吗？如果您可以发布代码块，我可以更具体。
