属性.记录.数据更新.草稿的值

{"FirstName": "This is my firstname","MiddleName": "This is my middlename","LastName": "this is my lastname"}

让新数据= JSON解析（属性记录数据更新草稿）
控制台日志（新数据）

{
  "FirstName": "This is my firstname",
  "MiddleName": "This is my middlename",
  "LastName": "this is my lastname"
}

这是我的数据库

id: {
    type: Sequelize.INTEGER,
    primaryKey: true,
    autoIncrement: true,
  },
  tableNameToBeUpdated: {
    type: Sequelize.STRING,
  },
  tableIdToBeUpdated: {
    type: Sequelize.STRING,
  },
  draft: {
    type: Sequelize.JSON,
  },
  CreatedDate: {
    type: Sequelize.DATE,
  },
  LastUpdateDate: {
    type: Sequelize.DATE,
  },
  status: {
    type: Sequelize.STRING,
  },

这里我想要的是得到标签（名字，姓氏，中间名）和透视值，

注 * 标签可以更改，这取决于保存在草稿列上的字符串

如何做到这一点？

node.js

大概是这样：

const jsonString = {"FirstName": "This is my firstname","MiddleName": "This is my middlename","LastName": "this is my lastname"}

for (var key in jsonString) {
       console.log(key + " -> " + jsonString[key]);
}

这将给出输出：

'FirstName -> This is my firstname'
'MiddleName -> This is my middlename'
'LastName -> this is my lastname'

编辑：好的，我从你的帖子中取了这个例子（没有单引号）。然后按照你的帖子做，然后使用for循环：

const jsonString = '{"FirstName": "This is my firstname","MiddleName": "This is my middlename","LastName": "this is my lastname"}'

const jsonObject = JSON.parse(jsonString)

for (var key in jsonObject) {
  console.log(key + " -> " + jsonObject[key]);
}
