convert an input value in array

I have this data in an input: [16,57.35], [23,56.26], [34,54.57]

and I want to turn it into an array

var data =$('#data').val();
var array = JSON.parse ("["+data+"]");

I'm having this error

Uncaught SyntaxError: Unexpected token.

How I can fix it or I can convert the input value in array?

Your code is working check it here, you may need to include required jQuery library or check some thing else in the code causing it.

data = $('#txt1').val();
arr = JSON.parse ("["+data+"]");
console.log(arr);

Try using the eval function:

var data = "123, 456, 789";
var array = eval("[" + data + "]");

You'll need to make sure that whatever you're inputting is valid JSON, but the above code will output an array for you. Hope it helps.
