Answer 1

Use JSON.parse:

var a = JSON.parse("[[1,2],[3,6],[8,10]]");

Edit

JSON.parse documentation on MDN

Answer 2

You can use the built-in JSON.parse() function:

flotdata = "[[1,2],[3,6],[8,10]]";
var my_obj = JSON.parse( flotdata );

// [ [Array[2],Array[2],Array[2]] ]

---

Reference - JSON.parse()

Parse a string as JSON, optionally transforming the value produced by parsing.

Answer 3

An alternative is:

flotdata = "[[1,2],[3,6],[8,10]]";
flotdata = eval(flotdata);
