My jQuery Mobile app consists of a single index.html page and contains only one page with a link on startup:

    I had some time to mess around with this and I've found a solution that works (tested).

    SOME NOTES:

    1. the javascript encapsulated in $(document).ready(); is for dynamically creating a page if the user navigates to your index.html file with a hash mark already appended (i.e. index.html#some_hash_mark).
    2. The function, create_page(page_id) is for creating a page from a link (or programatically if you like).
    3. Note that the jquery core script and the jquery mobile css are loaded before the $(document).ready() statement but that the jquery mobile script is loaded after.
    4. See that the body tag has been given an id that is refrenced when appending pages to it.

    //refresh the home screen so new link is given proper css
    $('#page_0 div[data-role="content"]').page();

    Here is my method for dynamically adding content to my Jquery Mobile websites:

    1. First I create a "wrapper" data-role=page div like so:

      <div data-role="page" id="my_page_id">
<div data-role="content">
    <script>
    $('#my_page_id').live('pageshow', function() {
        my_data_loading_function('my_page_id');
    });
    </script>
<div id="my_page_id-content"></div>
</div><!--/content-->
</div><!--/page-->

    2. Next I load data from an external source into a div tag located in my "wrapper" page: 

      function my_data_loading_function(page) {
    if ($('#' + page + '-content').is(':empty')) {
        $.mobile.pageLoading();
        $('#' + page + '-content').load("my_external_script.php", function() {
            $.mobile.pageLoading(true);
            $('#' + page + '-content ul').listview();
            $('#' + page + '-content ul').page();
        });
    }
}

    Some Notes:

    • $.mobile.pageLoading(); and $.mobile.pageLoading(true); show and hide (respectively) the Jquery Mobile loading spinner.

    • if ($('#' + page + '-content').is(':empty')) { allows the user to navaigate away from the dynamically created page and then come back and not have to re-load the data until a full page refresh occurs.

    • My dynamically created page included mostly a list so listview() makes the jquery mobile framework refresh the list selected to add the proper css, page() does the same to other page elements; however you may only need to use one or the other depending on your content (or none at all if its just plain text).

    • I realize this isn't creating a whole page dynamically because the "wrapper" page is already hard-coded but if you want to add a whole new page you can probably use something like: (untested)

      $(document).append('<div data-role="page" id="my_page_id"><div data-role="content">FOO BAR</div></div>');
$('#my_page_id').page();

    If you really want to make it all dynamically created you can check for window.location.hash and create your data-role=page div with the id set as the window.location.hash.

    Also I am using Jquery 1.6 and Jquery Mobile 1.0a4.1

    I hope something in there can help someone out there :)

    Have you looked at jquery's ajax load method? Seems like you could just have it load the page you want and replace the body each time you have a request come back.

    In this example on JSFiddle, I take an API call from Flickr and run the results through the jquery tmpl engine to append the new page to the to the document and then call $.mobile.changePage() to the newly inserted page. I think you'll see how useful the pairing of jquery tmpl + apis + jquery mobile is.
