a very simple way... 

$('select.sllist').change(function(){
   $('#my_hidden_field').val($('option:selected[value="1"]').length);
}).change();

$(".sllist").change(function() {
   var len = $(".sllist").filter(function() {
        return $(this).val() === "1";
    }).length;
    $("input").val(len);
}).change();

Demo.
