Assign Label value to HiddenField using JavaScript in ASP.Net

hi

there is TxtPhone and LblTshE in LblTshE will display count of number that users will typed into Txtphone below is code:

    <script type="text/javascript">
        $(function () {
            $('[id*=TxtPhone]').on("keyup", function () {
                var numbers = $(this).val().split(/\n/g);
                var count = 0;
                for (var i = 0; i < numbers.length; i++) {
                    if (numbers[i].trim() != '') {
                        count++;
                    }
                }
 
                $('[Id*=LblTshE]').html(count);
            });
        });
    </script>

  <script type="text/javascript">
        $(function () {
            $('[id*=TxtPhone]').on("keyup", function () {
                var numbers = $(this).val().split(/\n/g);
                var count = 0;
                for (var i = 0; i < numbers.length; i++) {
                    if (numbers[i].trim() != '') {
                        count++;
                    }
                }
 
                $('[Id*=LblTshE]').html(count);
                $('[id*=hfCount]').html($('[Id*=LblTshE]').html(count));
            });
        });
    </script>

but it doesn't work
