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!

Answer 1

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.

使用JSON.parse（）方法来做到这一点：

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