结合两个 arrays 创建 arrays 的 object

Question

https://stackblitz.com/edit/angular-enctgg-dvagm3 Problem statement: Am trying to patch the hours from arr2 to arr1 and then build the whole expected o/p as given below.

I was trying with map. But not sure how to traverse through nested array. Note: Array1 has nested array and need to map those into arrar2 code:

var result = this.responseValue.map((person, index) => ({ ppmInfoId: { locationCode: person.locationCode, yearMonth: person.locationType, changeOrderId: 20 },  hours: index}));

Expected output:

"ppmInfo": [
  {
    "ppmInfoId": {
      "changeOrderId": 0,
      "locationCode": 1,
      "yearMonth": "May/2021"
    },
    "hours": "10"
  },
  {
    "ppmInfoId": {
      "changeOrderId": 0,
      "locationCode": 1,
      "yearMonth": "June/2021"
    },
    "hours": "20"
  },      {
    "ppmInfoId": {
      "changeOrderId": 0,
      "locationCode": 2,
      "yearMonth": "May/2021"
    },
    "hours": "10"
  },
  {
    "ppmInfoId": {
      "changeOrderId": 0,
      "locationCode": 3,
      "yearMonth": "May/2021"
    },
    "hours": "10"
  }
]

Input Array 1:

 this.responseValue = [
          {
            locationCode: '1',
            locationType: 'Onsite',
            ppmDetailsToList: [
              {
                hours: 0,
                changeOrderId: null,
                yearMonth: 'May/2021',                
              },
              {
                hours: 0,
                changeOrderId: null,
                yearMonth: 'June/2021',                
              },
            ]
          },
          {
            locationCode: '2',
            locationType: 'Offshore',
            ppmDetailsToList: [
              {
                hours: 0,
                changeOrderId: null,
                yearMonth: 'May/2021',                
              },
            ]
          },
          {
            locationCode: '3',
            locationType: 'offsite',
            ppmDetailsToList: [
              {
                hours:0,
                changeOrderId: null,
                yearMonth: 'May/2021',
                locationCode: 0
              },
            ]
          }
        ];

Input array 2:

[{ "Onsite": [ 10, 20 ], "Offshore": [ 10 ], "offsite": [ 10 ] }]

Answer 1

 const array1 = [{ locationCode: '1', locationType: 'Onsite', ppmDetailsToList: [{ hours: 0, changeOrderId: null, yearMonth: 'May/2021', }, ] }, { locationCode: '2', locationType: 'Offshore', ppmDetailsToList: [{ hours: 0, changeOrderId: null, yearMonth: 'May/2021', }, ] }, { locationCode: '3', locationType: 'offsite', ppmDetailsToList: [{ hours: 0, changeOrderId: null, yearMonth: 'May/2021', locationCode: 0 }, ] } ]; const array2 = [{ "Onsite": [10], "Offshore": [10], "offsite": [10] }] const result = { ppmInfo: array1.map(({ locationCode, locationType, ppmDetailsToList: [{ hours, changeOrderId, yearMonth }] }) =>({ hours: array2[0][locationType][0], ppmInfoId: { changeOrderId: changeOrderId || 0, locationCode, yearMonth } })) } console.log(result)

Answer 2

Used foreach itself to get the desired output. Closing this
