将字符串格式的矩阵转换为Javascript数组

Question

I have an array containing arrays in HTML as a string

<div id='foo'>['A', 'B', [['C', 1, 2]]]</div>

What I want

var myArray = ['A', 'B', [['C', 1, 2]]];

I've been trying to grab it with something like $("#foo").text(); then convert it to a Javascript variable. Normally I'd just use data.split(',') , however with the sub array, things get messed up. I'd like to not use eval() . How can I convert this string into a js array?

Answer 1

Replace the single quotes to double quotes, and use JSON.parse() on the string to convert to an array:

 const result = JSON.parse(document.querySelector('#foo') .innerText .replace(/'/g, '"')); console.log(result)

 <div id='foo'>['A', 'B', [['C', 1, 2]]]</div>

Answer 2

var myArray = $('#foo').textContent

will get the values as a string and put in your variable. Do realize this does not convert it to Array. Do you really need it as array or as string?
