     if ((datestr = $(this).val()).length > 0) { 
      year = datestr.substring(datestr.length-4, datestr.length); 
      month = jQuery.inArray(datestr.substring(0, datestr.length-5), $(this).datepicker('option', 'monthNames')); 
      $(this).datepicker('option', 'defaultDate', new Date(year, month, 1)); 
      $(this).datepicker('setDate', new Date(year, month, 1));
