Data-transition effects does not work with tab navigation jquery mobile - jquery-mobile

I try to bring some effects to my tabs navigation on my jquery-mobile page but it looks like that the data-transitions argument does not work combined with a tabs navigation.
My code looks like this:
<div data-role="header" data-theme="a" id="header">
<h1>Mainpage</h1>
</div>
<div data-role="main" class="ui-content">
<div data-role="tabs" id="tabs" >
<div data-role="navbar" data-iconpos="left">
<ul>
<li><a id="lblTab1" href="#location" data-ajax="false" class="ui-btn-active" data-icon="search" data-transition="pop">search</a></li>
<li><a id="lblTab2" href="#product" data-ajax="false" data-icon="location" data-transition="pop">product</a></li>
</ul>
</div>
<div id="location" class="ui-body-d ui-content" > content </div>
<div id="product" class="ui-body-d ui-content" > content2 </div>
</div>
</div>
</div>
so how is it possible to bring some effects to the navigation bar?
I use jquery-mobile 1.4.0

Page transitions don't work on tabs as transition classes are activated when hiding/showing pages. You can create your own transitions, use third party CSS transitions or use jQM default ones.
First, you need to listen to tabbeforeactivate event. This event omits a ui object containing data of previous (ui.oldPanel) and next panel (ui.newPanel). All you need is to add animation classes to ui-newPanel and remove them once animation ends by binding Animation End one time only using .one().
$("#tabs").on("tabbeforeactivate", function (e, ui) {
$(ui.newPanel)
.addClass("animation")
.one('webkitAnimationEnd mozAnimationEnd MSAnimationEnd oanimationend animationend', function () {
$(this).removeClass("animation");
});
});

Popup not working within jquerymobile

I'm a touch lost - I have taken a popup example from the jquery demo page as a template...
If I put my popup within the first page, it works - I can call it from within js script to open.
Thus... the following does work
<div data-role="page" class="page" id="Menu">
<div data-role="header" data-position="fixed" class="ui-title center">
<div data-role="controlgroup" data-type="horizontal">
<span class='htitle'>Barserver.com</span>
</div>
</div>
<div id="MainContent">
<div id="MenuList"></div>
</div>
<div data-role="popup" id="popup" data-overlay-theme="b" data-theme="b" data-dismissible="false" style="max-width:400px;">
<div data-role="header" data-theme="a">
<h1>Delete Page?</h1>
</div>
<div role="main" class="ui-content">
<h3 class="ui-title">Are you sure you want to delete this page?</h3>
<p>This action cannot be undone.</p>
Cancel
Delete
</div>
</div>
I can dynamically open it via
$("#popup").popup("open");
However if I move the popup to another (data-role) page within the same document, it does not get displayed, nor errors in console.log. Can anyone steer me forward? The following does NOT work...
<div data-role="page" class="page" id="OrderList">
<div data-role="header" data-position="fixed" class="ui-title text-center">
<div data-role="controlgroup" data-type="horizontal">
<span class='htitle'>Barserver.com</span>
</div>
</div>
<div id="OrderListContent" class="productdhtml ui-content"></div>
<div data-role="popup" id="popup" data-overlay-theme="b" data-theme="b" data-dismissible="false" style="max-width:400px;">
<div data-role="header" data-theme="a">
<h1>Delete Page?</h1>
</div>
<div role="main" class="ui-content">
<h3 class="ui-title">Are you sure you want to delete this page?</h3>
<p>This action cannot be undone.</p>
Cancel
Delete
</div>
</div>
</div>
To avoid misunderstanding - the first code sample works, the second one does not work (meaning no errors, no modal like dialog box gets displayed).
Why?
(All help appreciated of course)
I got it (thanks to #Omar for direction). A coded answer is not easy but I will try draft and share in a few days (I'm behind on my work because of trying to fix this problem).
For the purpose of this note, when I say "this failed" I mean "no popup, no change in address bar, no console error."
I have a form. If operator attempted to navigate away, a test should be done to confirm all data was entered. All my a-href tags had page references, and jquery gives precedence to a-href tags over any other events I had applied. I had not considered the ramifications of this. The result? Form displayed, incompletely filled, operator selects to navigate elsewhere, popup call starts/ends but "failed" and jquery quickly navigates to the page named in the a-href page.
Solution:
When using popups, do not name pages in a-href tags. Thus, when using popups, avoid
<a href='#Page5'>Page 5</a>
and instead
<a href='#' id='page5'>Page 5</a>
and create an event that decides if a popup should be displayed, or if not, that page5 should be navigated to.
I hope that makes sense.

Multiple jQuery Mobile Collapsible: Having only one collapsible open at any time

Is there any way to make jQuery Mobile Collapsible elements close all other expanded collapsibles whenever you expand another collapsible element?
This is because in my collapsible list, I want only one item expanded at any time.
I checked the documentation, and theres an event that fires whenever you expand a collapsible. I included this in the <script> tag below. I'm not sure if this is the best way to do this or if its some other simple way to do it. And also I have no idea how to traverse the document to close all opened collapsibles.
<div data-role="collapsible">
<h3>Item 1</h3>
<p>Content 1</p>
</div>
<div data-role="collapsible">
<h3>Item 2</h3>
<p>Content 2</p>
</div>
<script>
$( ".selector" ).collapsible({
expand: function(event, ui) {
// code here to close all opened collapsibles, but i need input how to do this
}
});
</script>
The answer was simple.
jQuery Mobile will visually style a set of collapsibles as a group and will make the set behave like an accordion in that only one collapsible can be open at a time if you wrap the collapsibles in a div that has the attribute data-role="collapsibleset".
http://api.jquerymobile.com/collapsibleset/
Making the final code:
<div data-role="collapsible-set">
<div data-role="collapsible">
<h3>Item 1</h3>
<p>Content 1</p>
</div>
<div data-role="collapsible">
<h3>Item 2</h3>
<p>Content 2</p>
</div>
</div>

How to inject the same panel into multiple pages using jquery mobile

jQuery Mobile 1.3.1 has a very nice sliding panel feature, but the panel code must be placed within the same page it's used on.
I'm working on an app that needs to have the same panel on many pages. Instead of replicating code is there a way to dynamically inject the panel into these pages so that it will still retain the jqm panel functionality?
jQuery Mobile >= 1.4
Solution one:
Use an External panel that can be accessed from any page, this is in case you want to have the same panel contents in all pages.
Append panel to $.mobile.pageContainer once only on pagebeforecreate and then enhance the panel using $(".selector").panel().
var panel = '<div data-role="panel" id="mypanel" data-position="right" data-display="push"><h1>Panel</h1><p>stuff</p></div>';
$(document).one('pagebeforecreate', function () {
$.mobile.pageContainer.prepend(panel);
$("#mypanel").panel();
});
Add button to open the panel in each header (or wherever you want).
Note: When using External Panel data-theme should be added to panel div, as it doesn't inherit any styles/theme.
Demo
Solution two:
If you wish to do changes to panel before appending it, based on number of pages in DOM, add panel to each one with a different ID and a button to open that panel.
Note that you don't need to call any kind of enhancement, because you're adding panels on pagebeforecreate. Hence, panels will be auto-initialized once page is created.
var p = 1,
b = 1;
$(document).one('pagebeforecreate', function () {
$.mobile.pageContainer.find("[data-role=page]").each(function () {
var panel = '<div data-role="panel" id="mypanel' + p + '" data-position="right" data-display="push"><h1>Panel</h1><p>stuff</p></div>';
$(this).prepend(panel);
p++;
});
$.mobile.pageContainer.find("[data-role=header]").each(function () {
var panelBtn = ''
$(this).append(panelBtn);
b++;
});
});
Demo
Note: Make sure you use .one() not .on(), if you use the latter, panels will be added whenever a page is created.
jQuery Mobile <= 1.3
You can do it this way, using pagebeforecreate event and by checking if there is no Panel added already. Keeping in mind that panels markup should always be placed before [data-role=header] that's why I used .before().
There is no need to call any enhancement method since panels are added on pagebeforecreate. They will be initialized during that event.
Demo
Your panel
var panel = '<div data-role="panel" id="mypanel" data-position="right" data-display="push"><h1>Panel</h1><p>stuff</p></div>';
Add panels dynamically
$(document).on('pagebeforecreate', '[data-role=page]', function () {
if ($(this).find('[data-role=panel]').length === 0) {
$('[data-role=header]').before(panel);
}
});
Update
There are two alternative methods to inject "External Panel" dynamically.
For some one coming across this issue, there is something called External Panels in JQuery Mobile 1.4+, which can make our life easier.
http://demos.jquerymobile.com/1.4.0/panel-external/
You can do something like this.
<div data-role="panel" id="mainPanel">
<!-- .... -->
</div>
<div data-role="page" id="page1" >
<!-- .... -->
</div>
<div data-role="page" id="page2" >
<!-- .... -->
</div>
You can also do one thing create a panel at the end or start of all pages and open that by Id and script code mentioned below.....its working fine for me.
$(function(){
$("#navigation").enhanceWithin().panel();
});
<div data-role="page" id="page1">
<div data-role="main" class="ui-content ui-body-a ui-responsive">
<div data-role="header">
<div data-role="navbar">
<ul>
<li class="">
</li>
</li>
</ul>
</div>
</div>
</div>
</div>
<div data-role="page" id="page2">
<div data-role="main" class="ui-content ui-body-a ui-responsive">
<div data-role="header">
<div data-role="navbar">
<ul>
<li class="">
</li>
</li>
</ul>
</div>
</div>
</div>
</div>
<div class="ui-panel ui-panel-position-left ui-panel-display-reveal ui-body-b ui-panel-animate ui-panel-open" data-role="panel" id="navigation" data-position="left" data-display="overlay" data-theme="b" data-dismissible="true" data-swipe-close="true">
<div class="ui-panel-inner">
<ul class="">
</ul>
</div>
</div>
In order for hashcoder his response to work you need to initialize the external panel. Also add .enhanceWithin() to make listviews etc render properly within the panel.
Als add a data-rel=... attribute to the link via which you want to open the external panel.
<script>
$(function () {
$("div[data-role='panel']").panel().enhanceWithin();
});
</script>
<div data-role="panel" id="mainMenu">
<!-- .... -->
</div>
<div data-role="page" id="page1" >
Open main menu panel
<!-- .... -->
</div>
<div data-role="page" id="page2" >
Open main menu panel
<!-- .... -->
</div>

get header and footer out of the page dom

I'm building a mobile app with Cordova, Backbone for the MVC structure and jQuery Mobile for UI.
This works well except for the user experience while loading a new page. Actually a new page is created dynamically, and when it's ready, jquery mobile handles the page transition to this page. In a mobile browser this transition is slower than in a classic browser, so while page is loading the user sees a blank white screen and then appears the new page.
The matter is about my header/footer bar. I'd like it to keep showing while the content is loading, so the user will see the header/footer and only a blank/white content during the transition.
So this is a classic page structure:
<div data-role="page">
<div data-role="header"></div>
<div data-role="content"></div>
<div data-role="footer"></div>
</div>
For me the easiest way to go is like that:
<div data-role="header"></div>
<div data-role="page">
<div data-role="content"></div>
</div>
<div data-role="footer"></div>
And fix the content with CSS positioning.
But I'd like to find something smarter.
What do you think of having a single JQM page, with Backbone just updating the <div data-role="content"> for each route? What about JQM rendering? And what about transitions?
Documentation: http://jquerymobile.com/demos/1.1.0/docs/toolbars/footer-persist-d.html
Basically you put a data-role="footer" element in each page like this:
<div data-role="footer" data-id="foo-footer" data-position="fixed">
<div data-role="navbar">
<ul>
<li>Friends</li>
<li>Albums</li>
<li>Emails</li>
<li><a href="d.html" >Info</a></li>
</ul>
</div><!-- /navbar -->
</div><!-- /footer -->
Notice the data-id, it must be the same on all data-role="footer" elements to take advantage of the persistent toolbar option. The data-role="footer" element also must have the data-position="fixed" attribute.
Here is a demo: http://jsfiddle.net/SpRAA/

How to get alert to only appear once in jQuery Mobile multiple page html

I have a multipage html (using "div data-role="page") that displays 4 pages of a document that can be swiped left or right to move between the pages back and forth.
I have an alert that I want to pop-up only when the page first loads (telling the user they can swipe to move back and forth between pages).
My problem is that it keeps popping up again every time a swipe to a new page is made and I only want it to alert them once when the page loads.
I've tried moving the script from the head to inside the element, and I've tried binding it to all the different pagecreate, pagebeforecreate, pageinit, etc. events and can't seem to figure it out.
I appreciate any advice or direction.
Here's the alert code that is currently showing on every page when swiped:
<script type="text/javascript">
$('div').live("pagecreate",function(event){
alert('Swipe left and right to move between the 5 pages of this lead sheet');
});
</script>
You can bind to the id for the page DIV (ex: div#home).
<script type="text/javascript">
$('div#home').live("pagecreate", function (event) {
alert('Swipe left and right to move between the 5 pages of this lead sheet');
});
</script>
...
<div data-role="page" id="home">
Live Example:
http://jsfiddle.net/FcjNR/1/
JS
var $alerted = false;
$('div').live('pageshow',function(event, ui) {
// Check for secure token here
if($alerted == false) {
$alerted = true;
alert('Can you see me now?');
}
});
HTML
<div data-role="page" id="home">
<div data-role="content">
<ul data-role="listview" data-inset="true" data-theme="c" data-dividertheme="f">
<li data-role="list-divider">Alert once</li>
<li>Alert Page</li>
</ul>
</div>
</div>
<div data-role="page" id="alert">
<div data-role="content">
<ul data-role="listview" data-inset="true" data-theme="c" data-dividertheme="f">
<li data-role="list-divider">The Alert</li>
<li>Home</li>
</ul>
</div>
</div>
