如何在 JavaScript 中将 Object {} 转换为 Array [] 键值

问题描述

我想像这样转换一个对象:

I want to convert an object like this:

{"1":5,"2":7,"3":0,"4":0,"5":0,"6":0,"7":0,"8":0,"9":0,"10":0,"11":0,"12":0}

到这样的键值对数组中:

into an array of key-value pairs like this:

[[1,5],[2,7],[3,0],[4,0]...].

如何在 JavaScript 中将 Object 转换为键值对数组?

How can I convert an Object to an Array of key-value pairs in JavaScript?

推荐答案

你可以使用Object.keys() 和 map() 这样做

You can use Object.keys() and map() to do this

var obj = {"1":5,"2":7,"3":0,"4":0,"5":0,"6":0,"7":0,"8":0,"9":0,"10":0,"11":0,"12":0}
var result = Object.keys(obj).map((key) => [Number(key), obj[key]]);

console.log(result);
