我最近是这样做的:

const dummyObj = Object.assign({}, obj);
delete dummyObj[key];
const target = Object.assign({}, {...dummyObj});

您可以删除对象上的特定属性

items={
  item1: { key: 'sdfd', value:'sdfd' },
  item2: { key: 'sdfd', value:'sdfd' },
  item3: { key: 'sdfd', value:'sdfd' }
}

// Example 1
var key = "item2";
delete items[key]; 

// Example 2
delete items["item2"];

// Example 3
delete items.item2;

你能找到的最干净的方法是使用Lodash#pick

const _ = require('lodash');

const allowed = ['item1', 'item3'];

const obj = {
  item1: { key: 'sdfd', value:'sdfd' },
  item2: { key: 'sdfd', value:'sdfd' },
  item3: { key: 'sdfd', value:'sdfd' }
}

const filteredObj = _.pick(obj, allowed)

没有什么之前没有说过的，但是把一些答案结合到ES6的一般答案中:

Const raw = { Item1: {key: 'sdfd'， value: 'sdfd'}， Item2: {key: 'sdfd'， value: 'sdfd'}， Item3:{键:'sdfd'，值:'sdfd'} }; const filteredKeys = ['item1'， 'item3']; const filtered = filteredKeys .reduce((obj, key) =>({…Obj， [key]: raw[key]})， {}); console.log(过滤);

使用PropPick包

pick('item1 item3', obj);
// {
//   item1: { key: 'sdfd', value:'sdfd' },
//   item3: { key: 'sdfd', value:'sdfd' }
// }

好吧，这一行怎么样

    const raw = {
      item1: { key: 'sdfd', value: 'sdfd' },
      item2: { key: 'sdfd', value: 'sdfd' },
      item3: { key: 'sdfd', value: 'sdfd' }
    };

    const filteredKeys = ['item1', 'item3'];

    const filtered = Object.assign({}, ...filteredKeys.map(key=> ({[key]:raw[key]})));
