另一种使用数组的解决方案。在允许的键上减少方法:

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

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

const filtered = allowed.reduce((obj, key) => { 
  obj[key] = raw[key]; 
  return obj 
}, {})

console.log(filtered);

特别是对于较大的源对象(在本例中为原始对象)，这是有意义的。迭代不会使用源的所有条目执行，而只使用您想要过滤的键，因此更短/更快…

演示在这小提琴…

但我必须说，我也喜欢这个答案中的解决方案使用object。fromentries数组。filter和Array.includes:

const object = object . fromentries ( Object.entries(生)。Filter (([key, value]) => allowed.includes(key)) ）;

演示在这小提琴…

另一条捷径

函数filterByKey (v键){ const newObj ={}; keys.forEach(关键= > {v(例子)? newObj(例子)= v(例子):"}); 返回newObj; ｝ / /给定 让obj ={foo: "bar"， baz: 42,baz2:"blabla"， "spider":"man"， monkey:true}; / /当 let outtobj =filterByKey(obj，["bar"，"baz2"，"monkey"]); / /然后 console.log (outObj); / / { // "baz2": "blabla"， // "monkey": true / /}

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

下面的方法获取要过滤的对象和任何属性。

函数removeObjectKeys(obj，…keysToRemove) { let mObject ={…obj} for (let key of keysToRemove) { const{[字符串(键)]:_，…rest} = mObject mObject ={…休息} ｝ 返回mObject ｝ Const obj = {123: "hello"， 345: "world"， 567: "and kitty"}; const filtered = removeObjectKeys(obj, 123); console.log(过滤); const twoFiltered = removeObjectKeys(obj, 345,567); console.log (twoFiltered);

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]})));

一个不使用过滤器的更简单的解决方案可以通过Object.entries()而不是Object.keys()实现。

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

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

const filtered = Object.entries(raw).reduce((acc,elm)=>{
  const [k,v] = elm
  if (allowed.includes(k)) {
    acc[k] = v 
  }
  return acc
},{})
