JavaScript - How to split a string in two dimensional array?

Question

I need to split the string :

"[true,'3/5', 5],[true, '4/5', 5],[true, '5/5', 5],[true, '6/5', 5],[true, '7/5', 5],[true, '8/5', 5]"

In a bi-dimensional array:

[[true, '3/5', 5], [true, '4/5', 5], [true, '5/5', 5], [true, '6/5', 5], [true, '7/5', 5], [true, '8/5', 5]]

I have tried with:

var months = '[2010,1,2],[2010,3,2],[2011,4,2],[2011,3,2]';
var monthArray2d = [];
months.replace(/(\d+)_(\d+)/g, function(0,ドル 1,ドル 2,ドル 3ドル) {
 monthArray2d.push([parseInt(1ドル), parseInt(2ドル), parseInt(3ドル)]);
});
console.log(monthArray2d);

but without success

• Nina Scholz: your data does not match the one in the code.
• Luca Ruggeri: yes sorry a copy paste mistake
• Scott Sauyet: You can edit your question to show which is correct, the [true, '3/5', 5] format or the [2010, 1, 2] one.

Answer 1

So use JSON.parse, since your string has '' around the strings, it needs to be changed to "" so a replace statement can handle it. This assumes your data will not have extra quotes in it.

var str = "[true,'3/5',5],[true,'4/5',5],[true,'5/5',5],[true,'6/5',5],[true,'7/5',5],[true,'8/5',5]"
var arr = JSON.parse("[" + str.replace(/'/g, '"') + "]")
console.log(arr)

Answer 2

Since your string is almost valid JSON, I would just change all the single quotes into double quotes, wrap it into an array, then parse the entire structure:

const source_string = "[true,'3/5',5],[true,'4/5',5],[true,'5/5',5],[true,'6/5',5],[true,'7/5',5],[true,'8/5',5]";
const valid_json = source_string.replace( /'/g, '"' );
const array_wrapped = '[' + valid_json + ']';
const output = JSON.parse( array_wrapped );
console.log( output );
