title: Enable/Disable using Radio is not working
body: <p>I am trying to disable/enable dropdown box based on user selection of radio buttons. I have the following JSFiddle: <a href="http://jsfiddle.net/QekRS/" rel="nofollow"><strong>JSFiddle</strong></a> which works fine on it's own.</p>
  
  <pre><code>$('input[type=radio]').click(function() {
      var r_id = $("input[@name=sc]:checked").attr('id');
      alert(r_id);
  
      if (r_id == "bName") {
          //enable By Name drop down
          $(".dName").prop('disabled', false);
          //disable By Specialty drop down
          $(".dSpecialty").prop('disabled', true);
      }
      if (r_id == "bSpecialty") {
          //enable By Specialty drop down
          $(".dSpecialty").prop('disabled', false);
          //disable By Name drop down
          $(".dName").prop('disabled', true);
      }
  });
  </code></pre>
