Menu
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:
The HTML on each page:
<div data-role="footer" data-position="fixed" data-id="header">
<img src="images/bgheader.png" />
</div>
The JavaScript:
$('div.ui-footer').css('top', '0px');
$('div.ui-footer-fixed').css('top', '0px');
$('div.fade').css('top', '0px');
$('div.ui-fixed-overlay').css('top', '0px');
$('div.ui-bar-a').css('top', '0px');
The HTML on each page:
<div data-role="header" data-position="fixed" data-id="header" id="header" data-backbtn="false">
<img src="images/bgheader.png" />
</div>

A little bit of jquery will do the trick
<script type="text/javascript">
$(document).ready(function() {
$('#lpage1:first').addClass('ui-btn-active'); //set the first tab as active
firstContent=$('#content1'); //defining selectors
secondContent=$('#content2');
secondContent.hide(); //hide the second content division
});
// show only the first content div
function showContent1() {
firstContent.show();
secondContent.hide();
}
function showContent2() {
firstContent.hide();
secondContent.show();
}
//clicking on tab 2
$('#lpage2').live('tap',function(event){
//alert("click");
showContent2();
});
</script>
<body>
<!-- Start of first page -->
<div data-role="page" id="page1">
<div data-role="header" data-position="fixed">
<h1>Foo</h1>
<div data-role="navbar">
<ul>
<li><a href="#" id="lpage1" data-transition="pop">Home<br/> </a></li>
<li><a href="#" id="lpage2" data-transition="pop">My<br/>Profile</a></li>
</ul>
</div><!-- /navbar -->
</div><!-- /header -->
<!-- page1 -->
<div data-role="content" id="content1">
<p>I'm first in the source order so I'm shown as the page.</p>
<p>View internal page called <a href="#bar">bar</a></p>
</div><!-- /content -->
<!-- page2 -->
<div data-role="content" id="content2">
<p>I'm second in the source order so I'm shown as the page.</p>
<p>View internal page called <a href="#bar">bar</a></p>
</div><!-- /content -->
<div data-role="footer">
<h4>Page Footer</h4>
</div><!-- /footer -->
</div><!-- /page -->
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.

Add the following css to your page or to the bottom of the css file
Please note I have not tested this code on mobile devices..
<style type="text/css">
.ui-header {
position: fixed !important;
top: 0 !important;
z-index: 99;
}
.ui-content {
margin-top: 35px;
}
</style>
