I have the following code:
<div data-role="page" id="Page1" >
<!-- Footer here -->
<div data-role="footer" data-position="fixed" data-id="id-footer1">
<div data-role="navbar">
<ul>
<li>Page1</li>
<li>Page2</li>
</ul>
</div>
</div><!-- /footer -->
</div><!-- /page -->
<div data-role="page" id="Page2" >
<!-- Footer here -->
<div data-role="footer" data-position="fixed" data-id="id-footer1">
<div data-role="navbar">
<ul>
<li><a href="#Page1" >Page1</a></li>
<li>Page2</li>
</ul>
</div>
</div><!-- /footer -->
</div><!-- /page -->
The above codes will work if I use the following scripts. That is, Page 1 will have the Slide effect and Page 2 the Pop effect.
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.min.css" />
<script type="text/javascript" src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script type="text/javascript" src="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.min.js"></script>
However, when I used the following, the slide effect and pop effect are gone.
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.css" />
<script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.1.0/jquery.mobile-1.1.0.min.js"></script>
Seems like the new JQM version has affected the page transition or am I missing something? Can anybody confirm?
Thanks.
Read the transitions section in the announcement of 1.1.0:
Unfortunately, after a ton of work, we’ve determined that it’s not possible to dumb down
page transitions enough to get acceptable performance in Android 2.x, even on a newer device
like a Nexus S running 2.3. After a lot of deliberation, we’ve decided to use a feature test
for 3D transforms to target transitions: if a browser passes, it will see the full range of
transitions. By default, if a browser fails this 3D test, they will fall back to a fade
transition, regardless of the transition specified. All Android 1.x-2.x devices fail this
test but Android 3.x and 4.x pass. The fallback behavior for each transition is completely
configurable if you want to change this behavior.
If your testing browser doesn't support 3D transforms you will get a fade transition.

I am trying to build my first application on windows platform using phone gap. I am able to run my application but I'm not able to see any icon like back button, menu button icon in both emulator and device. How can we get the data-icons in page header.
CSS:
<script type="text/javascript" src="cordova.js"></script>
<script type="text/javascript" src="js/jquery.js"></script>
<link rel="stylesheet" href="css/jquery.mobile-1.4.2.css" />
<script type="text/javascript" src="js/jquery.mobile-1.4.2.js"></script>
HTML:
<div data-role="page" id ="pichartimg">
<div data-theme="a" data-role="header">
<h3>Pie Chart</h3>
Back
</div>
<div id='canvasDivpie' class = "sidebar"></div>
</div>
I'm not able to see the back button in page header. What is the issue and how to get icons.
I have been struggling with this too. My experience ist, that it's important to have the correct order in your Javascript inclusions.
I suggest you to first include your CSS. Then right after in the following order:
jQuery
Jquery Mobile
Cordova
any other Javascript
Done so the below example should display a button in your header with an icon on the right side:
<div id="header" data-role="header" data-position="fixed" data-theme="a">
<h1>Some Headline</h1>
</div>
Hope that helps!
I seem to be having some trouble setting up and playing with jquery mobile. The issue is that if you hover over list items in a ul you get a huge delay in the animation, same with hovering on the tablet. My page is simple and almost exactly taken from a jQuery mobile tutorial. You can see the code below or visit : aliahealthcare.com/jquerymobile to reproduce the same environment. Thanks!
my Code:
<!DOCTYPE html>
<html>
<head>
<title>My Page</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" />
<script src="https://code.jquery.com/jquery-1.6.4.min.js"></script>
<script src="https://code.jquery.com/mobile/1.3.2/jquery.mobile-1.3.2.min.js"></script>
</head>
<body>
<div data-role="page">
<div data-role="header">
<h1>Select a Class Type</h1>
</div><!-- /header -->
<div data-role="content">
<ul data-role="listview" data-inset="true">
<li><a href="#">
<img height="100px" src="https://static.webresint.com/images/micro.hostel.com/gallery/34561.jpg">
<h2>Day Class</h2>
<p>Broken Bells</p></a>
</li>
<li><a href="#">
<img src="http://sweetclipart.com/multisite/sweetclipart/files/sunset_hills.png">
<h2>Evening Class</h2>
<p>Hot Chip</p></a>
</li>
<li><a href="#">

<h2>Night Class</h2>
<p>Phoenix</p></a>
</li>
</ul>
</div><!-- /content -->
</div><!-- /page -->
</body>
</html>
The problem is that you are using very large images and rescaling them in the browser. The biggest culprit is sunset_hills.png. Here's a jsFiddle with just that image commented out and and you will already notice a huge difference in performance.
Instead of resizing your images using css or img attributes, you should use smaller versions of the images (even better you should try and use css sprites). If you need to support multiple sizes based on the screen size then you can accomplish this by displaying your images using css media queries.
That said I'm not exactly sure why there is such a big difference in performance between chrome and other browsers.
As a side point you are linking to the css for jQuery mobile 1.0.1 but you are using jQuery Mobile 1.3.2. Also JQM 1.3.2 supports jQuery 1.9.1 (while you are linking to jQuery 1.6.4).
As part of my first PhoneGap app, I need to load up an OpenLayers map (ultimately using my own local custom tiles, but for the moment, I'm just testing with online ones, modding the standard OpenLayers examples).
But when I try to initialise the map in the iOS simulator, the tiles don't want to load, using either OpenStreetMap or alternatives. The map initialisation gets as far as placing the controls, and the copyright notice, but I keep getting the blue question-mark boxes instead of live tiles. Testing the map-loading code independently in a browser, it seems to function properly if I remove the jQuery Mobile references, but that doesn't seem to work if I tweak the file in Xcode, and besides that, it screws up my desired appearance and behaviour. Is this a known conflict and does anyone know a way around it?
Thanks in advance!

Sorry - forget I spoke! Just discovered that I needed to add a reference to the map server domain to the "ExternalHosts" in Cordova.plist. Now the images seem to be loading okay.
I'm writing a Html 5 application for mobile devices using jQuery mobile (and Phonegap, but the following is device independent), using one html page that contains various <div data-role="page"... > elements as subpages. To change between one subpage and another I use $.mobile.changePage. Everything works well unless I place a div tag into one of the <div data-role="content"> containers!
Working example:
<!DOCTYPE html>
<html>
<head>
<title>App</title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.min.css" />
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script src="http://code.jquery.com/mobile/1.0/jquery.mobile-1.0.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$.mobile.changePage($('#page2'), {
transition : 'slideup',
reverse : false,
changeHash : true
});
});
</script>
</head>
<body>
<div data-role="page" id="page1" data-theme="a">
<div data-role="content">
Page1
</div>
</div>
<div data-role="page" id="page2" data-theme="a">
<div data-role="content">
Page2
</div>
</div>
</body>
</html>
Now, after adding something as simple as a closed div tag behind Page1
Page1 -> Page1<div />
$.mobile.changePage still fires - one can see the page2 content for a second - but then shows a blank screen.
This happens in desktop browsers as well as in a smartphone (using Phonegap and adjusting the code).
I really appreciate any kind of idea or hint. Narrowing down this problem and making it reproducible alone cost me hours a valuable livetime because it seemed to unlikely....
Change
Page1<div />
to
Page1</div>
...
Page1<div>test</div>
works too.
Not sure why jqm is having a problem with the trailing / on the empty div.
I think it's there in jQTouch but how do I add a full screen welcome image for my iPhone web app developed using jQueryMobile?
The app is a full screen web app and it is already added in the iPhone Homescreen.
This is just a concept but you could try something like this:
Live Example: http://jsfiddle.net/yzvWy/14/
JS
$(function() {
setTimeout(hideSplash, 2000);
});
function hideSplash() {
$.mobile.changePage("#home", "fade");
}
HTML
<div data-role="page" data-theme="b" id="splash" style="background-color: #fff;">
<div class="splash">
<img src="http://jquerymobile.com/demos/1.0a4.1/docs/_assets/images/jquery-logo.png" alt="splash" />
</div>
</div>
<div data-role="page" data-theme="b" id="home">
<div data-role="content">
<div data-role="content">
<ul data-role="listview" data-inset="true" data-theme="c" data-dividertheme="b">
<li data-role="list-divider">Overview</li>
<li>Intro to jQuery Mobile</li>
<li>Features</li>
<li>Accessibility</li>
<li>Supported platforms</li>
</ul>
</div>
</div>
</div>
iOS has its propertiary stuff for displaying a splash while app loads. I didn't use it yet (I didn't need that) but here's how they say it can be done:
<link rel="apple-touch-startup-image" href="img/splash.png" />
You might want this too:
<link rel="apple-touch-icon" href="./apple-touch-icon.png" />

Thanks for the help. This didn't work with the current stable release of Jquery Mobile, since it doesn't yet support 1.7. I managed to combine it another solution on the matter and came up with:
$ (function(){
setTimeout(function(){
$.mobile.changePage("#home", "fade");
}, 3000);
});
Thanks!
