                    </select>
                     <input type="hidden"  class="datepicker1" id="datepck1"/>
      </label>

  <script language="javascript">
       $(document).ready(function(){
         alert($("#datepck1").prev("select[name=date]").attr("name"));
  })

  </script>

prev() only matches the immediately previous sibling. You’re looking for prevAll():

alert($("#datepck1").prevAll("select[name=date]").attr("name"));
