Javascript 基于相似对象值匹配json对象时出错

在我的react应用程序中，我有两个包含用户测验结果的JSON对象。我的目标是使用循环中的某种循环生成roomSurveys中每个测验的答案与userSurvey答案相同的百分比值

  const [userSurvey, setUserSurvey] = useState({ "Q1":"A",
                                                 "Q2":"B, C, A",
                                                 "Q3":"C" });

  const [roomSurveys, setRoomSurveys] = useState({
                                         "user2":{ "Q1":"A",
                                                   "Q2":"B, C, C",
                                                   "Q3":"B" },
                                         "user3":{ "Q1":"C",
                                                   "Q2":"B",
                                                   "Q3":"B" },
                                               });

然后，计算公共答案的函数将更新如下状态：

const [roomMatches, setRoomMatches] = useState({
                                         "user2":{ "percentMatch":"1.0"},
                                         "user3":{ "percentMatch": ".30"}
                                               })

以下是我到目前为止得到的信息：

      //loop through each user survey in the roomSurvey object
      for (var key of Object.keys(roomSurveys)) {
        var countSame;
        var countTotal;
      //loop through each user survey within the roomSurvey object
        for (var key of Object.keys(roomSurveys[key])) {
          //if answer matches userSurvey answer for the same key,
          //add to count same and count total else, add to count total
          if(roomSurveys[key] == userSurvey[key]){
            countSame++;
            countTotal++;
          }else{
            countTotal++;
          }

          console.log(key + " -> " + roomSurveys[key])
          console.log(key + " -> " + userSurvey[key])
        }
        var percentMatched = countSame/countTotal;
        setRoomMatches([...roomMatches, {key:{['percentMatch']: percentMatched}}]);
      }

以下是我得到的错误：

• 在第二个for循环中，roomSurveys[key]值始终未定义
• roomMatches不可编辑（尝试将新匹配百分比添加到roomMatches状态时）

---

您已经在第二个for循环中写入了关键变量。您需要将它们命名为key1和key2（或更详细的名称）
如果对

key

变量使用相同的名称，请重命名它们并根据需要使用它们

。。。v
用于（对象键的var测量（房间测量））{
var计数相同；
var countTotal；
v
对于（Object.keys的变量室（roomSurveys[survey]））{
...

这些只是对象，不是json。
