function rolldice() {

    var x = Math.floor(Math.random() * ((6 - 1) + 1) + 1);

    var y = Math.floor(Math.random() * ((6 - 1) + 1) + 1);

    var dicetotal = x + y;

    var double = 0;

    $('.dice1').attr('id', dice + x);

    $('.dice2').attr('id', dice + y);

    if (x == y) { //<----checking if there is a double

        var double = double++; //<---increment double count

        //Now reroll the dice, but if you hit 3 doubles in a row, you get message go to jail.

    }

};

I want to know if I am going to need some loop...Please help me. This is part of a monopoly game. What do i have to add in the code, to make it loop if there is a double.
