javascript - 通过比较对象值动态数组中的对象键生成新的对象数组

问题描述

const payload = [
  {
    ControlType: 'Label',
    Property: 'FirstName'
  },
  {
    ControlType: 'DateTime',
    Property: 'CreatedOn'
  },
  {
    ControlType: 'Label',
    Property: 'Price'
  },
  {
    ControlType: 'Label',
    Property: 'SubTotal'
  },
  {
    ControlType: 'Label',
    Property: 'Total'
  }
];

const object1 = {
  ContactId: null,
  ContactName: null,
  CreatedOn: '05-06-2020 12:37 PM',
  CustId: '4069241-BR02',
  CustName: 'ABC',
  FirstName: 'Test',
  LastName: 'Test',
  SurName : 'Test',
  Total:500,
  Price: 200,
  SubTotal:400,
  Tax:100,
  Qty : 2
};

// 我需要下面的结果

const newResult = [
  {
    FirstName: 'Test',
    ControlType: 'Label'
  },
  {
    CreatedOn: '05-06-2020 12:37 PM',
    ControlType: 'DateTime'
  },
  {
    Price: 200,
    ControlType: 'Label'
  },
  {
    SubTotal: 400,
    ControlType: 'Label'
  },
  {
    Total: 500,
    ControlType: 'Label'
  }
];

解决方案

你可以map：

var payload = [ { ControlType: 'Label', Property: 'FirstName' }, { ControlType: 'DateTime', Property: 'CreatedOn' }, { ControlType: 'Label', Property: 'Price' }, { ControlType: 'Label', Property: 'SubTotal' }, { ControlType: 'Label', Property: 'Total' }];

var object1 = { ContactId: null, ContactName: null, CreatedOn: '05-06-2020 12:37 PM', CustId: '4069241-BR02', CustName: 'ABC', FirstName: 'Test', LastName: 'Test', SurName : 'Test', Total:500, Price: 200, SubTotal:400, Tax:100, Qty : 2};

var result = payload.map(({Property, ...rest})=>({[Property]:object1[Property], ...rest}));

console.log(result);
