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

all

我想像这样转换一个对象：

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

变成这样的键值对数组：

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

如何在 JavaScript 中将对象转换为键值对数组？

您可以使用Object.keys()并map()执行此操作

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);
