const filteredObject = Object.fromEntries(Object.entries(originalObject).filter(([key, value]) => key !== uuid))

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)

我很惊讶居然没有人提出这个建议。它非常干净，非常明确地告诉你想要保留哪些键。

const unfilteredObj = {a: ..., b:..., c:..., x:..., y:...}

const filterObject = ({a,b,c}) => ({a,b,c})
const filteredObject = filterObject(unfilteredObject)

或者如果你想要一个脏的眼线笔:

const unfilteredObj = {a: ..., b:..., c:..., x:..., y:...}

const filteredObject = (({a,b,c})=>({a,b,c}))(unfilteredObject);

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);

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;

你可以这样做:

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

const filtered = (
    source => { 
        with(source){ 
            return {item1, item3} 
        } 
    }
)(base);

// one line
const filtered = (source => { with(source){ return {item1, item3} } })(base);

这是可行的，但不是很清楚，加上with语句不推荐(https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/with)。
