javascript - 在对象javascript数组中插入对象

Question

我有两个对象数组:

{
"records": [
  {
      "lead_id": 97195,
      "user_id": 613,
      "segment_id": 0,
      "email_address": "asdf@lkasd.asd",
      "full_name": "asdf asdf",
  },
  {
      "lead_id": 97197,
      "user_id": 613,
      "segment_id": 0,
      "email_address": "asdfasdfasdf@asdasdasd.com",
      "full_name": "asdf asdf",
  }
  ]  
}

第二个对象数组:

  {
       "userTags": [
        {
          "lead_id": 97195,
          "user_tag_id": 93,
          "tag_name": "Julien",
        },
        {
          "lead_id": 97195,
          "user_tag_id": 93,
          "tag_name": "test123"
        },
        {
          "lead_id": 97197,
          "user_tag_id": 93,
          "tag_name": "General Business"
        },
        {
          "lead_id": 97197,
          "user_tag_id": 93,
          "tag_name": "PAREB CLRB"
        }
      ]
    }

我想在特定的 lead_id 对象上插入标记名，例如在记录中有 "lead_id": 97195 和 userTags "lead_id": 97195，这是我的捕捉器或提示，应该连接到该对象数组，但我不知道如何将 tag_name 对象插入 records 列表

示例输出

"records": [
  {
      "lead_id": 97195,
      "user_id": 613,
      "segment_id": 0,
      "email_address": "asdf@lkasd.asd",
      "full_name": "asdf asdf",.
      "tag_name": "Julien",
  }]

Answer 1

您可以使用 map 和 find 遍历您的记录并添加您在 中找到的 tag_name 字段userTags 对象。

但是，对于同一个 lead_id，您似乎有多个 tag_name。我添加了两个示例，一个采用第一个匹配的 lead_id 的 tag_name，另一个收集所有匹配的 lead_id 的所有 tag_name :

const records = {
  "records": [
    { "lead_id": 97195, "user_id": 613, "segment_id": 0, "email_address": "asdf@lkasd.asd", "full_name": "asdf asdf" },
    { "lead_id": 97197, "user_id": 613, "segment_id": 0, "email_address": "asdfasdfasdf@asdasdasd.com", "full_name": "asdf asdf" }
  ]  
};

const userTags = {
  "userTags": [
    { "lead_id": 97195, "user_tag_id": 93, "tag_name": "Julien" },
    { "lead_id": 97195, "user_tag_id": 93, "tag_name": "test123" },
    { "lead_id": 97197, "user_tag_id": 93, "tag_name": "General Business" },
    { "lead_id": 97197, "user_tag_id": 93, "tag_name": "PAREB CLRB" }
  ]
};

const newRecords = {
  records: records.records.map(record => {
    const lead_id = record.lead_id;
    const tag = userTags.userTags.find(tag => tag.lead_id === lead_id);
    return { ...record, tag_name: tag.tag_name };
  })
};

const newRecordsMult = {
  records: records.records.map(record => {
    const lead_id = record.lead_id;
    const tags = userTags.userTags
      .filter(tag => tag.lead_id === lead_id)
      .map(tag => tag.tag_name);
    return { ...record, tag_name: tags };
  })
}

console.log(newRecords, newRecordsMult);
