Javascript - 从对象开始维护关键顺序 - >排列 [英] Javascript - maintain key order when going from object -> array

问题描述

我知道JS对象不保证密钥顺序，但是，我的数据结构来自我无法控制的后端。从以下地方我可以做些什么来保存关键顺序：

I know key order isn't guaranteed in JS objects, however, my data structure comes from a backend for which I have no control over. Is there anything I can do to preserve the key order when going from:

var obj = {
   foo: 'bar',
   bar: 'foo' 
};

to：

Object.keys(obj); // hoping for ['foo', 'bar']

我保持最重要的不幸的是关键顺序......

It's of the utmost importance that I keep the key order unfortunately...

推荐答案

没有。正如您所写：

我知道JS对象中无法保证关键顺序

I know key order isn't guaranteed in JS objects

如果您需要订单，则需要使用数组。如果您有一个对象，则该属性没有已定义的顺序。

If you want the order you need to use an array. If you have an object, then there is no defined order to the properties.
