This will work for you..May be your'e ui jquery is not including properly.Use below code

External Links

<link rel="stylesheet" href="//code.jquery.com/ui/1.10.4/themes/smoothness/jquery-ui.css">
   <script src="//code.jquery.com/jquery-1.9.1.js"></script>
   <script src="//code.jquery.com/ui/1.10.4/jquery-ui.js"></script>

Script Here

 <script>
      $(function() {
        $( "#datepicker" ).datepicker();
      });
      </script>

HTML

<p>Date:<input type="text" id="datepicker"></p>
