As a person that used jQuery as a "golden hammer" for a long time, my advise would be to use the appropiate tool for each task. In this case, I'd use the shuffle() method in underscore.js for the task.

var new_array=_.shuffle([1, 2, 3, 4, 5, 6]);

var arr = [1,2,3,4,5,6];
arr = shuffle(arr);

function shuffle(arr) {
    for(var j, x, i = arr.length; i; j = parseInt(Math.random() * i), x = arr[--i], arr[i] = arr[j], arr[j] = x);
    return arr;
}
