Javascript 如何遍历数组并在json中添加字段

我想知道是否有人可以帮助我遍历这个数组，以便将cardNumber包含在deviceListJson中.

所以现在我有两个json文件，我把它们读出来了.

const deviceListData = await readJSON(deviceFilePath);
const playerListData = await readJSON(playersFilePath);

DeviceFilePath包含如下所有设备:

{
    "deviceId": "9331d5fwwd77",
    "slot": 1,
    "deviceType": "GAME"
},
{
    "deviceId": "9221d5fwwd77",
    "slot": 3,
    "deviceType": "GAME"
},
{
    "deviceId": "9001d5fwwd77",
    "slot": 10,
    "deviceType": "GAME"
},
{
    "deviceId": "9331d5fww007",
    "slot": 11,
    "deviceType": "GAME"
},
{
    "deviceId": "9331d5f00077",
    "slot": 19,
    "deviceType": "GAME"
}

PlayerListData包含所有的播放器信息json，如下所示:

{
    "cardNumber": "199",
    "firstName": "TIM",
    "middleName": "P",
},
{
    "cardNumber": "110",
    "firstName": "JACK",
    "middleName": "Z",
},
{
    "cardNumber": "111",
    "firstName": "MICKEY",
    "middleName": "A",
}

我想做的只是将一个随机的卡号从playerListData Json添加到deviceListData Json中.

例如，deviceListData json将如下所示:

{
    "deviceId": "9331d5fwwd77",
    "slot": 1,
    "deviceType": "GAME",
    "cardNumber": "111"
},
{
    "deviceId": "9221d5fwwd77",
    "slot": 3,
    "deviceType": "GAME",
     "cardNumber": "110"
},
{
    "deviceId": "9001d5fwwd77",
    "slot": 10,
    "deviceType": "GAME",
     "cardNumber": "199"
},
{
    "deviceId": "9331d5fww007",
    "slot": 11,
    "deviceType": "GAME",
    "cardNumber": "199"
},
{
    "deviceId": "9331d5f00077",
    "slot": 19,
    "deviceType": "GAME",
    "cardNumber": "111"
}

所以我做了一张这样的 map :

const cardNumber = playerListData.map((item) => item.cardNumber);
console.log(cardNumber);

它输出这个数组(我注意到它没有包括密钥，只包括卡号数组中的值)

[ '199', '110', '111' ]

当我将整个代码拼凑在一起时，发生的情况是它将playerListJson中的所有字段添加到DeviceListJson中，如下所示:

{
    "deviceId": "9331d5fwwd77",
    "slot": 1,
    "deviceType": "GAME",
    "cardNumber": "111",
    "firstName": "MICKEY",
    "middleName": "A"
},
{
    "deviceId": "9221d5fwwd77",
    "slot": 3,
    "deviceType": "GAME",
    "cardNumber": "110",
    "firstName": "JACK",
    "middleName": "Z"
},
{
    "deviceId": "9001d5fwwd77",
    "slot": 10,
    "deviceType": "GAME",
    "cardNumber": "199",
    "firstName": "TIM",
    "middleName": "P"
},
{
    "deviceId": "9331d5fww007",
    "slot": 11,
    "deviceType": "GAME",
    "cardNumber": "199",
    "firstName": "TIM",
    "middleName": "P"
},
{
    "deviceId": "9331d5f00077",
    "slot": 19,
    "deviceType": "GAME",
    "cardNumber": "111",
    "firstName": "MICKEY",
    "middleName": "A"
}

代码是这样的:

export async function assignPlayerCards() {
  try {
    const deviceListData = await readJSON(deviceFilePath);
    const playerListData = await readJSON(playersFilePath);
    const cardNumber = playerListData.map((item) => item.cardNumber);
    

    // Function to get a random card number from player list json
    function getRandomJson1Element() {
      const randomIndex = Math.floor(Math.random() * cardNumber.length);
      // console.log(cardNumber[randomIndex]);
      return playerListData[randomIndex];
    }

    // Update each element in device JSON with a random card number from player list JSON
    deviceListData.forEach((element) => {
      const randomElement = getRandomJson1Element();
      Object.assign(element, randomElement);
    });

   
    await writeJSON(deviceFilePath, deviceListData);
    console.log("Headers set for devices");
  } catch (error) {
    throw error;
  }
}

我做错了什么，我如何才能使它满足我的要求，即只需将cardNumber添加到deviceListJson中？
