My mobile website dynamically adds the header bar to reduce code redundancy.
However, I'm stuck with styling header section of a jquery mobile page.
When I see the generated HTML tags, it looks okay,
but its element is not decorated by jQuery Mobile.
After adding the content, I invoked
$(pageId).trigger('create');
Do you have any ideas?
This worked for me : http://jsfiddle.net/emBxx/2/
HTML:
<script type="text/javascript" src="js/main.js"></script>
...
<div data-role="page" data-theme="b">
<header></header>
<div data-role="content">
<div class="content-primary">
<br />
<ul data-role="listview" data-filter="true">
<li>Some</li>
<li>random</li>
<li>searchable</li>
<li>content</li>
<li>(list!)</li>
</ul>
</div><!--/content-primary -->
</div>
<footer></footer>
</div><!-- page end-->
<script>
appendJQMHeader('Injected header !');
appendJQMFooter('—Injected ftr!', 'JQM 1.3.1Beta');
</script>
JS, in js/main.js:
function appendJQMHeader(pageTitle) {
$('header').replaceWith(
'<header data-role="header" data-theme="f">'+
'<h1>'+pageTitle+'</h1>'+
'Home'+
'</header><!-- /header -->');
}
function appendJQMFooter(left, right) {
$('footer').replaceWith('<footer data-role="footer" data-theme="f" class="jqm-footer"><p>©'+left+'!</p><p class="jqm-version">—'+right+'</p></footer>');
}
Note: for JSfiddle, it require 'Framework & extension > No wrap - in <head>'
For stand alone version, it worked fine with html head calling js/main.js containing the JS. Then html body with appendJQMHeader() & appendJQMFooter(). See the fiddle :)
Instead of invoking the trigger method, I executed the below command, and it works well.
$('#pageHome').closest(":jqmData(role='page')").trigger('pagecreate');

I am new to jquery mobile.
I need help understanding the equivalent of document.ready() for jquery mobile.
I have 2 jsp pages as follow:
page1.jsp
<head>
<script type="text/javascript">
$(document).on('pagebeforeshow', '#page1', function(event){
alert("page 1");
});
</script>
</head>
<body>
<div data-role="page" id="page1">
<header data-role="header">
</header>
<article data-role="content">
page 1
</article>
<footer data-role="footer" data-position="fixed">
<nav data-role="navbar">
<ul>
<li>Page 2</li>
</ul>
</div>
</body>
page2.jsp
<head>
<script type="text/javascript">
$(document).on('pagebeforeshow', '#page2', function(event){
alert("page 2");
});
</script>
</head>
<body>
<div data-role="page" id="page2">
<header data-role="header">
</header>
<article data-role="content">
page 2
</article>
<footer data-role="footer" data-position="fixed">
<nav data-role="navbar">
<ul>
<li>Page 1</li>
</ul>
</div>
</body>
So when I initially load page 1, I will get an alert "page 1". But when I navigate to page 2, I do not get the alert "page 2"
But on page 2, I navigate back to page 1, I get an alert "page 1"
So why don't I get "page 2" alert when I load page 2 via navigation?
I am trying to learn jquery mobile so please an explanation and any code example would help to me understand it a lot.
I tried to read through jquery mobile documentation but not understanding it.
Thank you!
Your script isn't running because it technically isn't being loaded. jQuery Mobile follows links by intercepting their normal functionality (which is to navigate to a new page) and instead loads the page's content via an AJAX request. If successful, it then takes the [data-role=page] element and adds it to your existing page. The result is that the new page is loaded, but you never really leave the page that you started from.
Anything not within a [data-type=page] element is not loaded during this, including your scripts. You can fix this by by moving your <script> tag inside of page2's [data-role=page] element. If you do this, keep in mind that any code loaded this will will remain as other pages are loaded, and you might have things start interacting in ways you never intended.
Another option is to simply force jQuery Mobile to actually navigate to new pages when links are clicked. Check out their documentation for how to do that.
I'm facing an issue with the latest beta release of jQuery Mobile. I'm trying to implement a fixed persistent footer navbar, the persistent part is working but whenever I click a link and navigate to another page the ui-btn-active class is lost and no link appears selected.
Here's a demo fiddle that reproduces the issue: http://jsfiddle.net/koala_dev/DgdMg/2/
And here's the complete markup:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.4.0-beta.1/jquery.mobile.structure-1.4.0-beta.1.min.css" />
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.4.0-beta.1/jquery.mobile-1.4.0-beta.1.min.js"></script>
<script>
$(function() {
$("[data-role='header'],[data-role='footer']").toolbar();
$.mobile.window.triggerHandler("throttledresize");
});
</script>
</head>
<body>
<div data-role="header" data-position="fixed" data-id="header">
<h1>My fixed header</h1>
</div>
<div data-role="page" id="page-1">
<div data-role="content">
<p>Page 1 content goes here.</p>
</div>
</div>
<!-- /page -->
<div data-role="page" id="page-2">
<div data-role="content">
<p>Page 2 content goes here.</p>
</div>
</div>
<!-- /page -->
<div data-role="footer" data-position="fixed" data-id="footer">
<div data-role="navbar">
<ul>
<li>Page 1
</li>
<li>Page 2
</li>
</ul>
</div>
</div>
</body>
</html>
I followed the instruction from the demos in the docs (which don't seem to be complete) and placed the footer outside the page container. I tried adding .ui-state-persist to the first link and to both links but it didn't produce any effect and since even the demos are not working correctly I'm not sure how to proceed.
I would appreciate any insight on how to keep the ui-btn-active class for the clicked link.
Well, I found this on jQM updated demo page. Adding .ui-btn-active for external fixed toolbars depends on data-role=page's data-title attribute.
<div data-role="page" id="page-1" data-title="Page 1">
Navbar buttons text, should match data-title in order to determine which button should be updated with .ui-btn-active, as well as updating data-role=header title.
Demo
$(document).on("pageinit", function () {
$("[data-role='navbar']").navbar();
$("[data-role='header'], [data-role='footer']").toolbar();
});
// Update the contents of the toolbars
$(document).on("pageshow", "[data-role='page']", function () {
// Each of the four pages in this demo has a data-title attribute
// which value is equal to the text of the nav button
// For example, on first page: <div data-role="page" data-title="Info">
var current = $(this).jqmData("title");
// Change the heading
$("[data-role='header'] h1").text(current);
// Remove active class from nav buttons
$("[data-role='navbar'] a.ui-btn-active").removeClass("ui-btn-active");
// Add active class to current nav button
$("[data-role='navbar'] a").each(function () {
if ($(this).text() === current) {
$(this).addClass("ui-btn-active");
}
});
});

I had this same issue for links in the navbar. It was very frustrating. I fired up firebug and debugged jqm. I ended up patching the jquery mobile code like so:
In jquery.mobile-1.4.0.js
From:
$navbtns.removeClass( $.mobile.activeBtnClass );
activeBtn.addClass( $.mobile.activeBtnClass );
To:
if ( !($navbtns.filter( ".ui-state-persist" ) ) ) {
$navbtns.removeClass( $.mobile.activeBtnClass );
activeBtn.addClass( $.mobile.activeBtnClass );
}
I minified jqm here: http://jscompress.com/
A new thing in version 1.4.0 alpha 2 of jQuery-Mobile is that panels no longer have to be inside the page that uses them. Instead, external panels can be siblings to the pages.
This works fine with static pages:
<div id="panel" data-role="panel" data-theme="b" data-position="left"
data-display="push">
<h3>This is a panel</h3>
</div>
<div data-role="page" id="staticPage">
<div data-role="header" data-position="fixed">
Panel
<h1>Static page</h1>
</div>
<div data-role="content">
<div class="content-primary">
Go to dynamic page
</div>
</div>
</div>
<script type="text/javascript">
$(document).ready(function () {
$('#panel').panel();
});
</script>
However, when I generate and inject a page dynamically, the link to the panel no longer works as it is supposed to:
<script type="text/x-template" id="dynamicPageTemplate">
<div data-role="page" id="staticPage">
<div data-role="header" data-position="fixed">
Panel
<h1>Dynamic page</h1>
</div>
<div data-role="content">
<div class="content-primary">
<a href="#staticPage" data-role="button" data-inline="true">
Go to static page
</a>
</div>
</div>
</div>
</script>
<script type="text/javascript">
$(document).bind("pagebeforechange", function (e, data) {
if (typeof data.toPage === "string") {
var url = $.mobile.path.parseUrl(data.toPage);
if (url.hash.search(/^#dynamicPage$/) !== -1) {
$('#dynamicPage').remove();
var template = $("#dynamicPageTemplate").html();
var $page = $(template);
$page.attr('id', 'dynamicPage');
$('body').append($page);
$page.page();
$.mobile.changePage($page, {changeHash: false});
e.preventDefault();
}
}
});
</script>
When I click the "Panel" button in header of the dynamic page, the URL changes to …#panel and nothing is shown. I suspect that jQuery-Mobile tries to show the panel as a page rather than a panel. Am I doing something wrong, or is this a bug?
Fiddle with complete example
jQuery Mobile 1.4 panel (and a lot of other widgets) implementation still don't work correctly. Several new components are not even implemented yet. Not to mention, demo site was not updated since they announced alpha version 1.
Let me get back to pane implementation. It is still under heavy development. Any panel inner content (except buttons) is not properly styled. Just add a listview and see a final result.
Only thing you can do is wait for RC1 versions, or maybe just maybe first beta version (but I wouldn't hold my breath for the beta release).
Given a basic jQuery Mobile Collapisible Set, how can I get AJAX content before the toggle event fires? I am using jQM to create the following:
<div id="test" data-role="collapsible-set" data-inset="false">
<div data-role="collapsible" data-collapsed="true" data-mini="true">
<h2>Title #1</h2>
<ul data-role="listview"></ul>
</div>
<div data-role="collapsible" data-collapsed="true" data-mini="true">
<h2>Title #2</h2>
<ul data-role="listview"></ul>
</div>
</div>
I want to be able to when a user clicks on the "toggle" fire of an AJAX call to get content from the server and place it in the correct ul. I can figure out how to do everything except intercept the "click". I have tried binding on both click and expand on the div's, h2's and even ul's.
I am looking for something like:
$('#test h2').live('click',function() {
// do my AJAX call here to get li's to put in correct ul (assuming none exist)
});
Surely I am missing something super simple.
Ok...Here is a working example (minus the AJAX). The biggest drawback is that this only "fires" on expand. But by then it has already expanded and thus currently shows a blank space. What is really needed is a "before expanding" or "click" event so that you can inject the content you want and then the default can happen (changing icons, showing, etc). Not sure how to go about proposing that...

</div>
$("#set div:jqmData(role='collapsible')").each(function () {
$(this).bind('expand', function() {
if($(this).find('li').length < 1) {
// do ajax call here to get data
$(this).find('ul').append(items).listview('refresh');
}
});
});
$('#page #set li').live('click',function () {
alert('Go to item');
});
i thought this would be a problem of jquery-mobile 1.1.0 RC.
But also in the final release i got this weird problem, that my header overlaps my content div:
When i now click somewhere in the content div, the page rerenders and the content div is at the correct position(directly beneath the header).
I'm using Backbone.js Views for representing content, and jquery-mobile-router. I tried almost everything but i counldn't find any solution for this problem.
Does anyone know a solution for that?
html:
<!-- newsoffers page -->
<div data-role="page" id="newsoffers">
<div data-role="header" data-theme="a" data-fullscreen="false" data-position="fixed">
</div>
<!-- /content -->
<div data-role="content" data-scroll="true" class="content-full">
</div>
<!-- /content -->
<div id="newsoffersFooter" data-role="footer" data-position="fixed" data-fullscreen="false" data-id="mainFooter" data-theme="b">
</div>
<!-- /footer -->
</div>
the code for the header is dynamically injected! The content will be injected while the "pagebeforeshow" event is fired.
"setNavBarCollection" adds a backbone collection to the header, which is then rendered as a navbar.
The "refreshOffers" function generates a view containing a backbone collection which is fetched asynchronously.
