jQuery mobile how to detect refresh

Question

Some background;

By default when you click a link to a separate HTML page JQM loads the first data-role=\"page\" on that page and attaches it to the DOM of the f

One way to alleviate some pain is to put your page-specific scripts inside data-role="page" element in the appropriate html files and keep scripts that are the same for every page outside that element (at the and of the body and/or head).

That way even if the user refreshes the page all necessary scripts will still be executed. One problem though, before binding any handlers you need to unbind them first. Otherwise you'll end up having multiple handlers attached.

To illustrate this:

in login.html (updated):

<div data-role="page" id="loginpage">
    <script>
        $(document).off('pageinit', '#loginpage').on('pageinit', '#loginpage', function() {
            $(document).off('click', '#btnaccount').on('click', '#btnaccount', function(){
                $.mobile.changePage("jqmaccount.html", {reloadPage: true});
            });
            console.log("paginit in loginpage");
        });
        $(document).off('pageshow', '#loginpage').on('pageshow', '#loginpage', function() {
            console.log("pageshow in loginpage");
        });
    </script>
    <div data-role="content">
        <a id="btnaccount" href="#" data-role="button">Account</a>
    </div>
</div>

in account.html (updated):

<div data-role="page" id="accountpage">
    <script>
    $(document).off('pageinit', '#accountpage').on('pageinit', '#accountpage', function() {
        $(document).off('click', '#btnlogout').on('click', '#btnlogout', function(){
            $.mobile.changePage("jqmlogin.html", {reloadPage: true});
        });
        console.log("pageinit in accountpage");
    });
    $(document).off('pageshow', '#accountpage').on('pageshow', '#accountpage', function() {
        console.log("pageshow in accountpage");
    });
    </script>
    <div data-role="content">
        <a id="btnlogout" href="#" data-role="button">Logout</a>
    </div>
</div>

In this setup if the user refreshes account.html the Logout button on that page will still work.
