如何在node.js中将字符串等数组转换为数组? [英] How to convert an array like string to array in node.js?

问题描述

实际上我是从node.js中的android设备获取arraylist的.但是因为它是字符串形式，所以我想将其转换为array.为此，我在SO中提到了很多类似的问题，但是它们都没有帮助.我也尝试使用JSON.parse()，但是它没有帮助.

Actually I'm getting the arraylist from android device in node.js . But as it's in string form so I wanna convert it into an array . For that I've referred a lot of similar questions in SO but none of them were helpful . I also tried to use JSON.parse() but it was not helpful.

我正在以'[[艺术，摄影，写作]'"的形式获取SocietyList.那么如何将这种格式转换为数组?

I'm getting societyList in form '[Art, Photography, Writing]'.Thus how to convert this format to an array?

代码:

var soc_arr=JSON.parse(data.societyList)
            console.log(soc_arr.length)

推荐答案

使用类似

var array = arrayList.replace(/^\[|\]$/g, "").split(", ");

更新:

在使用@drinchev建议后使用正则表达式.

UPDATE:

After @drinchev suggestion regex used.

regex匹配char以'['开始，以']'

regex matches char starts with '[' and ends with ']'
