我在firestore中有一个数据库字段,其中有一个这样的地图:
坐标:{_ 01:“铜”,_02:“金”,_03:“铁”}
我在Firestore管理面板中看到此数据库,如下所示: pic
当我尝试使用以下代码列出项目
data.cordinates.map((item,i)=>
console.log(i+" - "+item)
);
我收到:
Unhandled Rejection (TypeError): data.cordinates.map is not a function
读/写这种地图的正确方法是什么?
btw console.log(data.cordinates)给我这样的输出:
{_01: "copper",_02: "gold",_03: "iron",_04: "",_05: "", …}
_01: "copper"
_02: "gold"
_03: "iron"
