You don't need if else part
$(document).ready(function () {
  $("#textbox").keyup(function () {
    var box = $(this).val();
    var main = box.length * 100;
    var value = (main / 140);
    var count = 140 - box.length;
    $('#count').html(count);
  });
});

Hmmm...ok

  $(document).ready(function () {
                                            $("#textbox").keyup(function () {
                                                var box = $(this).val();
                                                var count = 140 - box.length;
                                                if (box.length <= 140) {
                                                    $('#count').html(count);
                                                }
                                                else {
                                                $(this).attr("readonly","readonly");
                                                }
                                            });
