问题描述

我在JavaScript中有一个一维整数数组，我想从逗号分隔的字符串中添加数据，有没有简单的方法呢?

I have a one-dimensional array of integer in JavaScript that I'd like to add data from comma separated string, Is there a simple way to do this?

例如:var strVale ="130,235,342,124";

e.g : var strVale = "130,235,342,124 ";

推荐答案

您可以拆分然后使用 parseInt 将其转换为整数数组.

You can split and then use parseInt to convert it into integer array.

//get this from localStorage
var strValue = "130,235,342,124"; 
var res = strValue.split(',').map(x=>{return parseInt(x)});
console.log(res);
