    Here is one way that I hope is easy to understand:

    http://jsfiddle.net/tft4t/

    $(document).ready(function() {
 $("#chkdwn2").click(function() {
   if ($(this).is(":checked")) {
      $("#dropdown").prop("disabled", true);
   } else {
      $("#dropdown").prop("disabled", false);  
   }
 });
});

    A better solution without if-else:

    $(document).ready(function() {
    $("#chkdwn2").click(function() {
        $("#dropdown").prop("disabled", this.checked);  
    });
});

    try this

     <script type="text/javascript">
        $(document).ready(function () {
            $("#chkdwn2").click(function () {
                if (this.checked)
                    $('#dropdown').attr('disabled', 'disabled');
                else
                    $('#dropdown').removeAttr('disabled');
            });
        });
    </script>
