title: jQuery UI datepicker will not display - full code included
body: <p>I am having trouble displaying the jQuery datepicker as shown here:
  <a href="http://jqueryui.com/demos/datepicker/" rel="noreferrer">http://jqueryui.com/demos/datepicker/</a></p>
  
  <p>I believe I downloaded all of the proper files, but to be certain, I started from scratch and ripped the demo site.  Not all of it, but what I believed to be the important parts.  The result is no datepicker to be shown and no javascript errors.  Here is my full code sample:</p>
  
  <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt;
  &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt;
  &lt;head&gt;
   &lt;link rel="stylesheet" href="http://static.jquery.com/ui/css/base2.css" type="text/css" media="all" /&gt;
   &lt;link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/themes/base/jquery-ui.css" type="text/css" media="all" /&gt;
   &lt;link rel="stylesheet" href="http://static.jquery.com/ui/css/demo-docs-theme/ui.theme.css" type="text/css" media="all" /&gt;
  
  
  &lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" charset="utf-8" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/jquery-ui.min.js"&gt;&lt;/script&gt;
  
  &lt;script type="text/javascript" charset="utf-8"&gt;
   jQuery(function(){
    jQuery("#datepicker").datepicker();
   });
  &lt;/script&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;input type="text" id="datepicker" class="hasDatepicker" /&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>Any help would be very much appreciated.  Thanks!</p>
