如何将带有数组的字符串转换为数组 [英] How to convert a string with arrays to an array

问题描述

如何将此响应转换为有效数组？

我想执行 Object.map 关于数据：

How do I convert this piece of response into a valid array?
I want to perform an Object.map on the data:

var user_roles = "['store_owner', 'super_admin']";

这不是有效的JSON所以我不能使用 JSON.parse

This is not a valid JSON so I can't use JSON.parse

推荐答案

对，这里发布的大多数答案建议使用 JSON.parse 然后在被删除之前被投票3次。人们忽略了缺少符合JSON标准的报价。但是字符串IS是有效的JavaScript。您可以执行以下操作：

Right, most answers posted here suggest using JSON.parse and then get downvoted 3 times before getting deleted. What people overlook here is the lack of JSON-compliant quotation. The string IS, however, valid JavaScript. You can do the following:

const obj = {
  thing: "['store_owner', 'super_admin']",
  otherThing: "['apple', 'cookies']"
}

for (const key in obj) {
  const value = obj[key];
  obj[key] = eval(value);
}

console.log(obj);

输出将是一个有效的javascript对象：

Output will be a valid javascript object:

{"thing":["store_owner","super_admin"],"otherThing":["apple","cookies"]} 

小心<$但是，c $ c> eval（）！ javascript eval（）and security
