title: jQuery datepicker set selected date, on the fly
body: <p>How can I change the selected date of jquery Date picker dynamically on the fly?
  I have say created a inline date picker.
  Then after some time, I want to reflect a different date there without recreating the datepicker from the scratch.</p>
  
  <p>I tried the setDate method, but did not work, and there is not much documentation in the <a href="http://docs.jquery.com/UI/Datepicker" rel="noreferrer">doc</a>.</p>
  
  <p>There is another (extended?) plugin <a href="http://www.kelvinluck.com/assets/jquery/datePicker/" rel="noreferrer">here</a>, but I want to use the plugin which is shipped with jquery.ui.all.js.</p>
