title: In jquery mobile 1.3.1 how do you set selected value in a selectmenu?
body: <p>I have tried numerous things.  Nothing seems to work.</p>
  
  <p>for example:</p>
  
  <pre><code>$('#select').val(myval).selectmenu('refresh');
  $('#select').val(myval).attr('selected', 'selected');
  $('#select').val(myval).prop('selected',true);
  </code></pre>
