将数组数组的字符串转换为数组的Javascript数组的优雅方法? [英] Elegant way to convert string of Array of Arrays into a Javascript array of arrays?

问题描述

我有一个ajax请求，它返回这样的值列表:

I have an ajax request that returns a list of values like this:

"[-5, 5, 5], [-6, 15, 15], [7, 13, 12]"

我需要它是一个带有数字的javascript数组:

I need it to be a javascript array with numbers:

[[-5, 5, 5], [-6, 15, 15], [7, 13, 12]]

我试图用'|'替换'['和']'然后除以"|"并将foreach项除以'，'并将它们添加到数组中，但这完全不优雅.

I tried to replace the '[' and ']' for a '|' and then split by '|' and foreach item split by ',' and add them to an array, but this is not elegant at all.

你们有什么建议吗?

推荐答案

您可以使用

You can use JSON.parse() to convert that string into an array, as long as you wrap it in some brackets manually first:

var value = "[-5, 5, 5], [-6, 15, 15], [7, 13, 12]";
var json = JSON.parse("[" + value + "]");

console.log(json);

我建议，如果可能，请更正服务器上的输出.

I would suggest correcting the output at the server if possible, though.
