根据指定的数组过滤对象道具 [英] Filter object props based on the specified array

问题描述

我有一个具有以下结构的对象

I have an object with the following structure

{ cardControlItem: 'Tidak',
  cardDirectUseItem: 'Tidak',
  kbUnspscUuid: '6a564b8e-2976-4fde-8759-7951970d7500',
  substoreUuid: '2f2b04bb-8b80-4b1f-b827-bf20311e31ee',
  cardDetailMin: 654,
  cardDetailMax: 65,
  cardDetailIncrement: 754,
  cardDetailPriceOverall: 4534,
  cardDetailPriceUnit: 0,
  ltMeasurementMinUuid: 'fddca37a-d0a3-40a4-8537-e84375b01601',
  ltMeasurementMaxUuid: '2bc6d7d2-5167-4459-9910-a65839008afd' }

我在数组中有一个键列表

and I have a list of keys in an array

['cardControlItem', 'cardDirectUseItem', 'kbUnspscUuid', 'substoreUuid', 'stockCardGroupUuid', 'stockCardBatchUuid']

如何根据指定的数组减少它

How do I reduce it according to the array specified

预期输出:

{ cardControlItem: 'Tidak',
  cardDirectUseItem: 'Tidak',
  kbUnspscUuid: '6a564b8e-2976-4fde-8759-7951970d7500',
  substoreUuid: '2f2b04bb-8b80-4b1f-b827-bf20311e31ee' }

推荐答案

尝试此解决方案.我正在过滤obj(filter部分)中的属性，然后遍历存在的属性(reduce部分)，然后将属性的值分配给新对象(acc).

Try this solution. I am filter the properties which are in the obj (filter part) and then iterate over the properties which exist (reduce part) and assign values of the properties into new object (acc).

const obj = { 
   cardControlItem: 'Tidak',
   cardDirectUseItem: 'Tidak',
   kbUnspscUuid: '6a564b8e-2976-4fde-8759-7951970d7500',
   substoreUuid: '2f2b04bb-8b80-4b1f-b827-bf20311e31ee',
   cardDetailMin: 654,
   cardDetailMax: 65,
   cardDetailIncrement: 754,
   cardDetailPriceOverall: 4534,
   cardDetailPriceUnit: 0,
   ltMeasurementMinUuid: 'fddca37a-d0a3-40a4-8537-e84375b01601',
   ltMeasurementMaxUuid: '2bc6d7d2-5167-4459-9910-a65839008afd' 
};

const keys = ['cardControlItem', 'cardDirectUseItem', 'kbUnspscUuid', 'substoreUuid', 'stockCardGroupUuid', 'stockCardBatchUuid'];

const mapped = keys.filter(key => obj.hasOwnProperty(key))
                   .reduce((acc, key) => { acc[key] = obj[key]; return acc }, {});

console.log(mapped);
