将 json 键名添加到 json 值并更改键名

Question

I have a json string that is in the format:

[
  {
   clientIDs:
         "WELL #6",
   analyteIDs:
         [
          "7440-62-2",
          "7440-28-0"
         ]
  }
]

I need to convert this to:

[
  {
   header:
         "WELL #6",
   items:
         [
          header: "7440-62-2",
          header: "7440-28-0"
         ]
  }
]

The values without a key name are throwing me off.

Answer 1

Unfortunately js cannot store a key value arrays, instead you have to use an object storing key and value. So the closes result you can achieve is following:

 [ { header: "WELL #6", items: [ { header: "7440-62-2" }, { header: "7440-28-0" } ] } ]

For that your steps will be following:

• Assuming you have an array of objects.
• Assuming the keys you want to change are static and will always exist in the objects

 const myObjects = [ { clientIDs: "WELL #6", analyteIDs: [ "7440-62-2", "7440-28-0" ] } ] myObjects.map((myObj) => { myObj['header'] = myObj.clientIDs; myObj['items'] = myObj.analyteIDs.map((item) => { return { header: item } }); // Keep in mind, if keys are dynamic and does not exist in some objects then this will fail delete myObj['clientIDs']; delete myObj['analyteIDs']; }); console.log(myObjects);
