Loading page in 1.3.0

Loading page in 1.3.0

Hi.

How do I modify this code or where to add (example taken from starting guide) to show a loading page:

I just added a link to page2.php in content section.

Thanks

<!DOCTYPE html> <html> <head> <title>Page Title</title> <meta name="viewport" content="width=device-width, initial-scale=1"> 

<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.0-rc.1/jquery.mobile-1.3.0-rc.1.min.css" />

 <script src="http://code.jquery.com/jquery-1.8.3.min.js"></script> <script src="http://code.jquery.com/mobile/1.3.0-rc.1/jquery.mobile-1.3.0-rc.1.min.js"></script>

</head>
 <body>
<div data-role="page">
<div data-role="header">
<h1>Page Title</h1> </div><!-- /header -->
<div data-role="content">
<ul data-role="listview" data-inset="true">
<li>
<a href="page2.php" rel="external">Senderos</a>
</li>

</ul>
</div><!-- /content --> </div><!-- /page -->
