Not sure if I am in the right section for this. I am currently designing a web page using javascript, html and css. The page is a seat booking seat which allows the user to select and unselect seats. I have managed to get the page to display id of the seat when the user have selected a seat, but I am having problems trying to remove id from the display if user unselects the seat.

Below is the javascript code

$('.available, .unavailable, .selected').click(function(){
        var ID = $(this).attr('class');
        if (ID == 'n unavailable' || ID == 'p unavailable') {
            alert ('Seat is already booked. Please select another seat.');
        }
        else if (ID == 'n selected' || ID == 'p selected') {
            alert ('You have now unselected this seat.');
            $(this).html('<img src = "free.gif"/>');
            $(this).removeClass('selected').addClass('available');
            y--;
            $("#seats").html("Number of seats selected: " + y);
            $("#list").remove($(this).attr('id'));
        }
        else {
            alert ('You have now reserved this seat. You can unselect it by clicking the seat again.');
            $(this).html('<img src = "selected.gif"/>');
            $(this).removeClass('available').addClass('selected');
            y++;
            $("#seats").html("Number of seats selected: " + y);
            $("#list").append($(this).attr('id') + "</br>");
        }
    });
