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);
