title: Not finding defaultDate in jQuery UI datepicker
body: <p>I have a form text field that pulls a date from a database (in the format yyyy-mm-dd).</p>
  
  <pre><code>&lt;input class="" type="text" name="closingDate" id="closingDate" value="&lt;?php echo $closingdate;?&gt;" /&gt;@ Midday
  </code></pre>
  
  <p>I then have a jQuery datepicker that will grab its 'defaultDate' value as the value attribute of the input shown above.</p>
  
  <pre><code>$(document).ready(function(){
   $("#datepicker").datepicker({defaultDate: 'input#closingDate.attr('value')' , altField: 'input#closingDate' , altFormat: 'yy-mm-dd'});
  });
  </code></pre>
  
  <p>(plz note: yy-mm-dd is correct to format as yyyy-mm-dd, also $closingdate correctly echo's out as yyyy-mm-dd as i have checked it elsewhere in the page).</p>
  
  <p>However the datepicker will not grab the date from the input field, it simply defaults to its 'today' value.</p>
