将JSON字符串解析为数组 [英] Parse JSON string into an array

问题描述

我正在尝试从JSON解析字符串并将这些元素转换为Javascript中的数组。这是代码。

I'm trying to parse a string from JSON and turn those elements into an array in Javascript. Here's the code.

      var data = "{"fname":"Todd","lname":"James","cascade":"tjames","loc":"res","place":"home", "day0":"0,1,2,3,"}";
      var getDay = data.day0;
      var getDayArray = getDay.split(",");

基本上，我正在尝试获取day0，即0,1,2,3，以及把它变成一个结构为

Essentially, I'm trying to get day0, which is 0,1,2,3, and turn it into an array with a structure of

[0] = 0
[1] = 1
[2] = 2
[3] = 3

什么是最好的方法要做这个吗？

What is the best way to go about doing this?

推荐答案

这样的事情。这个尾随逗号有意吗？

Something like this. Is that trailing comma intentional?

var getDayArray = JSON.parse(data).day0.split(",")
