javascript - 省略数组中具有空字符串的对象键

Question

如何简化下面的数组

[ { uuid: '',
    quantity: 3,
    procurement_detail_uuid: '',
    distribution_officer_uuid: '',
    substore_uuid: '2343423443423' },
  { uuid: '',
    quantity: 3,
    procurement_detail_uuid: '',
    distribution_officer_uuid: '',
    substore_uuid: '676767' } ]

至

[ { quantity: 3,
    substore_uuid: '2343423443423' },
  { quantity: 3,
    substore_uuid: '676767' } ]

减少和过滤这些键的最快方法是什么？

Answer 1

Map数组，reduce每个对象的 keys ，并且只取非空值:

const data = [{"uuid":"","quantity":3,"procurement_detail_uuid":"","distribution_officer_uuid":"","substore_uuid":"2343423443423"},{"uuid":"","quantity":3,"procurement_detail_uuid":"","distribution_officer_uuid":"","substore_uuid":"676767"}];

const result = data.map((o) => Object.keys(o)
  .reduce((r, k) => o[k] !== '' ? Object.assign(r, { [k]: o[k] }) : r, {})
);

console.log(result);
