我最近是这样做的:

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

在循环过程中，当遇到某些属性/键时，不返回任何内容，并继续执行其余的:

const loop = product =>
Object.keys(product).map(key => {
    if (key === "_id" || key === "__v") {
        return; 
    }
    return (
        <ul className="list-group">
            <li>
                {product[key]}
                <span>
                    {key}
                </span>
            </li>
        </ul>
    );
});

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)。

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);

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;
