使用变量作为对象键

Question

我希望将变量插入对象键结构中，但我只获取变量名称而不是变量值。

var winnerId = 10;
var loserId = 11;        

newMessage.setMessageData({
  winnerId : {
    "status" : "win",
    "choice" : playerData[winnerId]["currentChoice"],
    "newScore" : playerData[winnerId]["score"]
  },
  loserId : {
    "status" : "lost",
    "choice" : playerData[loserId]["currentChoice"],
    "newScore" : playerData[loserId]["score"]
  }           
});

Answer 1

您应该使用计算属性名称：

newMessage.setMessageData({
    [winnerId]: {
        "status": "win",
        "choice": playerData[winnerId]["currentChoice"],
        "newScore": playerData[winnerId]["score"]
    },
    [loserId]: {
        "status": "lost",
        "choice": playerData[loserId]["currentChoice"],
        "newScore": playerData[loserId]["score"]
    }
});
