replace json key with another json value using node js / javascript-CodePudding

testDetails.map(function(data){
 
let JsonData={
 title: data["title"],
 url: data["url"],
 firstName: data["username"],

 work:[{workid:data["workid"].slice(","), workname: "tester"}],
 employee: [{employee_id: data["employee_id"].slice(","), employee_desk:"custom"}]
}
})

so my above json output look like this

{
 "title":"01"
 "url":"[email protected]",
 "firstName":"employee name",
 "work":[{"workid":"9371", "workname": "tester"}],
 "employee":[{"employee_id":"weh34",employee_desk:"custom"}]
}

and another JSON object where data look like this

let data={
  "031w":"ewid3728e",
  "9371":"emp_01",
   "weh34":"work_place01"
}

The workid and employee id with the JsonData I want to replace with the value which is present inside the data json so my data which is look like this

 "work":[{"workid":"9371", "workname": "tester"}],
 "employee":[{"employee_id":"weh34",employee_desk:"custom"}]

needed to be look like this

 "work":[{"workid":"work_place01", "workname": "tester"}],
 "employee":[{"employee_id":"emp_01",employee_desk:"custom"}]

I am trying to replace the code manually like this

 work:[{workid:data.weh34, workname: "tester"}],
 employee: [{employee_id: data.9371, employee_desk:"custom"}]

but data["workid"].slice(",") and data["employee_id"].slice(",") always get changed so I want to match both the json and fetch the value and place it in my JsonData

CodePudding user response：

Just use the value you got from testDetails as the index in the data object to get the corresponding value.

You need to use a different variable from data as the parameter to the mapping function so you can refer to the external variable data. I changed it to d below.

testDetails.map(d => ({
  title: d["title"],
  url: d["url"],
  firstName: d["username"],
  work: [{
    workid: data[d["workid"].slice(",")],
    workname: "tester"
  }],
  employee: [{
    employee_id: data[d["employee_id"].slice(",")],
    employee_desk: "custom"
  }]
}));
