如何使用单个删除从对象删除多个属性? [英] How to delete multiple properties from an Object using a single delete?

问题描述

我有以下对象:

var myArr = {one:'1',two:'2',three:'3',four:'4',five:'5'};

我想一次从该对象中删除三个属性:

I want to delete three properties from that object at once like:

delete myArr[one, three, five];

，并且失败.我是否必须为每个属性执行独立删除，如:

and it is failing. Do I have to perform an independent delete for each property like so:

delete myArr[one]; delete myArr[three]; delete myArr[five];

谢谢.

推荐答案

您可以使用数组作为键，并迭代删除.

You could use an array for the keys and iterate for deleting.

var object = { one: '1', two: '2', three: '3', four: '4', five: '5' };

['one', 'three', 'five'].forEach(function (k) {
    delete object[k];
});

console.log(object);

使用 Reflect.deleteProperty

var object = { one: '1', two: '2', three: '3', four: '4', five: '5' };

['one', 'three', 'five'].forEach(Reflect.deleteProperty.bind(null, object));

console.log(object);
