Turn a string formatted as an array into an array using javascript/ jQuery

Question

I am trying to turn a string like:

"[["firstVal","secondVal"],["firstVal","secondVal"]]"

Into a javascript array (It is a 2D array)

Is there a way that I can do this using javascript or jQuery?

Many Thanks!

you could also use eval, even though you shouldn't. jsfiddle.net/nLzkne3r — I wrestled a bear once.

You can use JSON.parse to achieve what you require:

var str = '[["firstVal","secondVal"],["firstVal","secondVal"]]';
var arr = JSON.parse(str);
console.log(arr);

Note that I had to amend the outer quotes to ' as your example string is malformed.

Use JSON.parse() method to do that :

JSON.parse('[["firstVal","secondVal"],["firstVal","secondVal"]]');
