Generate a random array in Javascript/jquery for Sudoku puzzle

I want to fill the 9 x 9 grid from the array by taking care of following condition:

var sudoku_array = ['1','2','3','4','6','5','7','8','9'];
$('.smallbox input').each(function(index) {
    $(this).val(sudoku_array[Math.floor(Math.random()*sudoku_array.length)]);
});

1. A particular number should not be repeated across the same column.
2. A particular number should not be repeated across the same row. When I execute the above mentioned code it fills all the 9 X 9 grid with random values without the above mentioned condition.How can I add those two condition before inserting values into my 9 X 9 Grid.
