Persistent header in jQuery Mobile

Asked 2011-06-06T22:44:34.647

Couldn't figure out a way to put a bounty on my old question, so I'm reposting it because maybe it was a bug.

Short version: I want a persistent header in a PhoneGap+JQM application that stays in-place (never moves) between page transitions like the footer can be designed to do.

Long version: First off, I'm totally new to jQuery and JQM, so please point out any newb mistakes I've made.

I'm trying to get a header that persists between different pages in the application. It would have to be like the persistent footer that stays in place whenever the user is transitioning between pages. The persistent footer was achieved using data-role="footer" data-id="(some consistent id)" data-position="fixed". It worked fairly well (random glitches with it getting misplaced then automatically fixing itself after a couple seconds). For more information on what I'm looking for, see "Persistent Footer" here: http://jquerymobile.com/test/docs/#/test/docs/toolbars/docs-footers.html

And see the example of the persistent footer at the link below. See how selecting an item in the footer transitions to a completely new page, yet the footer doesn't move: http://jquerymobile.com/test/docs/#/test/docs/toolbars/footer-persist-a.html

Now I'm trying to do the same thing, but I want it to be at the top of the application instead of the bottom. I've tried the following things:

Shifting the footer to the top of the page (don't know what tag to catch in jQuery. Tried div.(jQuery class) utilizing several jQuery classes, but none work. I used FireBug to determine it is the "top" CSS attribute that needs to be changed.

The HTML on each page:

<div data-role="footer" data-position="fixed" data-id="header"&g

                        I've been banging my head against this problem for several days, and for once Google was no help. I finally came up with the following solution. It copies the header HTML onto a new page before the transition begins, then removes the code from the previous page once the transition completes. The header and footer will still move with the page transition, but they will persist even while navigating nested lists.

// dynamically move the header and footer between pages on load events
$('div.ui-page').live('pagebeforeshow', function(event, ui) {
    // avoid duplicating the header on the first page load
    if (ui.prevPage.length == 0) return;

    // remove the jQuery Mobile-generated header
    $('.ui-header').addClass('to-remove-now');
    $('#header').removeClass('to-remove-now');
    $('.to-remove-now').remove();

    // grab the code from the current header and footer
    header = $('#header')[0].outerHTML;
    footer = $('#footer')[0].outerHTML;

    // mark the existing header and footer for deletion
    $('#header').addClass('to-remove');
    $('#footer').addClass('to-remove');

    // prepend the header and append the footer to the generated HTML
    event.currentTarget.innerHTML = header + event.currentTarget.innerHTML + footer;
});

// remove header from previous page 
$('div.ui-page').live('pagehide', function(event, ui) {
    $('.to-remove').remove();
});


Then just add id="header" to the header div and id="footer" to the footer, and place them as you normally would in your content.

                        Hi it might be late but this worked for me.

[data-role=page]
{
    min-height: 100%;
    height: auto !important;
    height: 100%;
    overflow: scroll;
    margin: 0 auto -40px;
}
.footerPlaceHolder
{
    height: 40px;
}
[data-role=footer]{height:40px; bottom:0; position:fixed !important; top: auto !important; width:100%; z-index: 9999;}


Your html

<div data-role="page">
    ....Your content....
    <div class="footerPlaceHolder"></div>
    <div data-role="footer"> 
        <a href="#" data-icon="arrow-l" class="ui-btn-left">Back</a>
        <a href="#" onclick="settingsClicked(this);" data-icon="gear" class="ui-btn-right">Settings</a> 
    </div>
</div>


P.S. Please note I am not good at this things especially css. All comments will be greatly appreciated.

Thanks.
