Where can I get a working js lib object to query string?

Question

JavaScript

Good afternoon!
Please throw in a working library so that it correctly transforms the constructions:

{
    a1 : [
        {b1 : 'value', s2 : 'value'},
        [
            {d3 : '1'},
            [1,2,3,4]
        ]
    ]
}

To a normal query string (example: ?a[0][a]=d&s[0][f]=g&s[1][s]=a&d[1][d]=f&d=).
Thank you!
