javascript – 如何使用单个删除从Object中删除多个属性？

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,如：

delete myArr[one,three,five];

它失败了.我是否必须为每个属性执行独立删除,如下所示：

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

谢谢.

解决方法

您可以使用数组作为键并迭代进行删除.

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

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

console.log(object);

随着Reflect.deleteProperty

var object = { one: '1','five'].forEach(Reflect.deleteProperty.bind(null,object));

console.log(object);
