why does the test message shows twice on:

<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
    <script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
    <script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
</head>
<body>
    <script type="text/javascript">
        alert("Test");
    </script>
</body>
</html>

I copied the headers from from http://jquerymobile.com/demos/1.2.0/docs/about/getting-started.html and as I started doing some examples I noticed that my javascript methods where being called twice.

Here is the code in JsFiddle:

    As Explosion Pills perfectly stated you have to play by jQM rules. At least:

    <div data-role="page" id="page1">
    <div data-role="header">
        <h1>Page Title</h1>
    </div><!-- /header -->
    <div data-role="content">    
        <p>Page content goes here.</p>        
    </div><!-- /content -->
    <div data-role="footer">
        <h4>Page Footer</h4>
    </div><!-- /footer -->
</div><!-- /page -->

    $(function() {   
    alert("Test");
});

    use

    $(document).on("pageinit", "#page1", function(){
    alert("Test");
});
