using jQuery UI 1.9.2 (upgraded from 1.8.23) and I see this on the Upgrade guide;
Deprecated url method and use of title attribute; use aria-controls attribute
(#7132) The url method has been deprecated in favor of leaving the href attribute unmodified even for remote tabs. The href attribute will point to the actual resource and the aria-controls attribute will point to the associated panel. This means that the title attribute will no longer be used to specify a custom panel id.
I have this code:
var $t = $("#tabs");
$t.tabs("url", 0, url);
$t.bind("tabsload", function (event, ui) {
console.log('tabsload fired');
});
$t.tabs("load", 0);
I cannot figure out how to set the url value for the tab (this code is fired when the user clicks on a grid row and the url value is rebuilt based on grid values) now as I do not understand the upgrade guide to use the aria-controls comment.
The approach I have taken is to set the href of the AJAX link and then call the load method to reload the content.
I appreciate that this does not use the aria-controls attribute, but the snippet from the upgrade guide states that this attribute points to the panel - remote tabs receive their content based on anchor contained in the li element, so I figured I should be able to use this approach.

</form>

</html>
I am using a generic HTTP handler (this is the AJAX request) which simply echos back the text it is passed, e.g., Handler1.ashx?echo=some text to repeat. Note that my tabs consist of only one tab that makes an AJAX call to this handler.
To change the Url, I handle the click event of the button and modify the href of ajax-link like this and then reload it:
$('#ajax-link').attr('href', 'Handler1.ashx?echo=changed at '
+ new Date().toTimeString());
$('#tabs').tabs('load', 0);
So for this to work you will need to provide the link you wish to change with an ID and you will need to know at which position the tab page occurs.

I am using a multiple page format with a persistent header. I can successfully change page either with a straight hyperlink or using $(':mobile-pagecontainer').pagecontainer('change'
The code works fine but it seems to "load" the page an additional time each time I click on the buttons to change page.
In this code the button changes the page and outputs a console.log message.
On click I would expect the page to change and to see one "#btn - page x" console.log message.
What happens is the page changes and I get a console message for each time I've loaded the page, not just one.
Even though my code is working, this can't be right - this will just go up and up with normal user usage.
What am I not understanding here?
I've created a jsfiddle to show what I mean. For example, if I click the "goto page x" button 6 times (that's 3 times for each page), I get an output of 3 "#btn - page x" messages, not just one.
Same with the header button - each time I change the page, number of responses from the header button goes up.
the html:
<!DOCTYPE html>
<html>

<meta charset="utf-8">

and the js:
$(document).on('pagebeforeshow','#page1',function(){
console.log('#page1 pagebeforeshow');
$('#btntest1').click(function(){
console.log('#btn - page1');
//$(':mobile-pagecontainer').pagecontainer('change', '#page2', { reloadPage: false});
});
});
$(document).on('pagebeforeshow','#page2',function(){
console.log('#page2 pagebeforeshow');
$('#btntest2').click(function(){
console.log('#btn - page2');
//$(':mobile-pagecontainer').pagecontainer('change', '#page1', { reloadPage: false});
});
});
$(function() {
$("[data-role='header']").toolbar();
});
$(document).on('pagebeforeshow',function(){
console.log('pagebeforeshow');
$('#headerbtn').click(function(){
console.log('headerbtn click');
});
})
UPDATE:
So I've been trying all sorts of things to try to fix this, including removing data-rel="back", trying data-ajax="false" (which defeats the point of what I'm trying to do), changing page with
$(':mobile-pagecontainer').pagecontainer('change', '#page2');
or
$(':mobile-pagecontainer').pagecontainer('change', '#page2', { reloadPage: false});
but no joy. Obviously, I've tried googling but can't find anything to help.
In the full app code the buttons communicate with a database, so as the clicks increase, I'm sending and retrieving the same data to the db multiple times on each click.
I really would appreciate some guidance if anyone has any ideas what I could do?
The problem is that each time you're entering the page, you are binding a listener on the element again. So you're binding multiple listeners. The listener should not be written inside the pagebeforeshowhandler.
Take it out like this:
$(document).on('pagebeforeshow','#page1',function(){
console.log('#page1 pagebeforeshow');
});
$('#btntest1').click(function(e){
e.preventDefault();
console.log('#btn - page1');
$(':mobile-pagecontainer').pagecontainer('change', '#page2', { reloadPage: false});
});
And for page 2 likewise.
I have problem with mobile/tablet version of page which I create
I need this: When someone look at product detail and move him to right/left (touch/swipe) then I need load next/previous product detail (= Example: Now I on page with id=2 when I go right, then I load page with id=3, npw I on page with id=3 and I go left then I load page with id=2.. etc.. with different pages id).
I look in thread here, but this solution is not dynamic and I have problem applicate it. Next I inspirated in W3C here.
Now I have these codes which not work:
JS file:
$(document).on('pageinit', function() {
$('.epicFullscreen').bind('swipeleft', function(event,ui)
{
$.mobile.changePage("http://www.some_domain.cz/category/page_name-1/","slide");
});
$('.epicFullscreen').bind('swiperight', function()
{
$.mobile.changePage("http://www.some_domain.cz/category/page_name-3/","slide");
});
});
$(document).on('pagehide', function () { $(this).off('swipeleft swiperight'); });
HTML:
<script src="funkce/jquery-1.7.1.min.js" type="text/javascript"></script>
<script src="funkce/jquery.mobile-1.3.2.min.js" type="text/javascript"></script>
<script src="funkce/skripty.js" type="text/javascript"></script>
I need use old JQuery 1.7.1. because this site using it and everything works fine, with newer JQuery I can have new problems. For that I use older JQuery-mobile 1.3.2. which must work with JQuery 1.7.1. ("jQuery Mobile 1.3 supports jQuery 1.7 and newer") . I can´t include "jquery.mobile-1.3.2.min.css" because this styles not work together with my styles correctly.
HTML in body is like that:
<div class="epicFullscreen">
<img class="epicImg" src="../../data_9/11normal.jpg" alt="inspirace č.2" title="inspirace č.2" border="0" />
</div>
Now I have dynamic solution with arrows (right/left) and with adding correct urls with PHP, but on tablet/mobile user like using touch not clicking on arrows etc...
=> Where I have problem and why not work my current solution? And how I can change this static JS to dynamic JS?
try this simple code .....
$(document).on("swipeleft", '#'+event.target.id, function () {
var nextpage = $(this).next('div[data-role="page"]');
if (nextpage.length > 0) {
alert(nextpage.attr('id'));
$.mobile.changePage(nextpage, "slide", false, true);
}
});
$(document).on("swiperight", '#'+event.target.id, function () {
var prevpage = $(this).prev('div[data-role="page"]');
if (prevpage.length > 0) {
$.mobile.changePage(prevpage, { transition: "slide", reverse: true }, true, true);
}
});
I found solution for that I make this answer. I simplify my problem and create simple page.
Code

I have this one hack - in PHP I know on which page I am, which page is before and which is next, I add this links it to arrows (which have tag "a"). This function working perfect. But I use this functional code to get correct URL => I don´t need some big function in JQuery which can split actual url with RegEx, know on which page I am, know if exist next page etc... Now I must only style this code to my page, but this is working.
I thank Omar for his time and I close this topic.
I am using the method noted here in the docs to set data-ajax="false" on a parent container for my site but I do have a few cases where I want the page to load via Ajax.
Is there a way to set the default on the parent container but allow individual links to override that setting? Adding data-ajax="true" to the individual links doesn't seem to work.
To set default for full page load:
$(document).on("mobileinit", function(){
$.mobile.ajaxEnabled = false;
});
To set individual, use data-ajax=true.
Somehow other suggestions didn't work for me. But this one did work. Tested.
This script disables all ajax links in the page jquery mobile - and those that should be ajax ones can be used as the a-link below with data-ajax=true.

I am at my wits end with jQuery Mobile events. I do not understand them, despite following the docs to the T. I am using the following code to initialize my pages. The problem is that some seem to fire multiple times and occasionally when I go back to a page nothing will appear, as though .live pageinit simply doesn't fire at all. I am quite confused. Is pageinit the way to go? is .live best practice? Do I need to clean up after myself and use something like pagehide to remove stuff from the DOM? Please help me understand. Thanks!

You could try something like this:

<link rel="stylesheet" href="./css/jquery.mobile-1.1.0.min.css" />

<script type="text/javascript" src="./js/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="./js/jquery.mobile-1.1.0.min.js"></script>
<!-- END - BASIC INCLUDES -->
</header>
<body>
<!-- PAGE 1 -->
<div data-role="page" data-theme="a" id="dashboardPage">
<script>
// INITIALIGE PAGE 1 - dashboardPage
$("#dashboardPage").live('pageinit',function(event){
alert( '"initializing" page 1: dashboardPage');
});
</script>
HERE YOU ARE AT PAGE 1 (dashboardPage)!!!<br><br>
CLICK HERE TO GO TO PAGE 2 (specialsPage)
</div>
<!-- PAGE 2 -->
<div data-role="page" data-theme="a" id="specialsPage">
<script>
// INITIALIGE PAGE 2 - specialsPage
$("#specialsPage").live('pageinit',function(event){
alert( '"initializing" page 2: specialsPage');
});
</script>
HERE YOU ARE AT PAGE 2 (specialsPage)!!!<br><br>
CLICK HERE TO GO TO PAGE 1 (dashboardPage)
</div>
</body>
</html>
Hope it helps.
When using JQuery mobile you should consider you have a single page which content is updated dynamically. You do not navigate from one page to the other as you normally would.
Because of this, any code present in a page you navigate to with JQM simply be ignored (tyr changing the header of page number 2, and navigate to this page from page number 1 with changepage, you will not see any difference).
Because of that, all your js code should be directly available within the page in which your user will arrive.
If you add the following code in the scripts of page 1, you will proeperly detect the initialization of of page2 when it is loaded with changepage.
$("#specialsPage").live('pageinit',function(event){
alert( '"initializing" page 2: specialsPage');
});
An important thing to keep in mind is that you user might also directly access your page2, which means that all the code should also be available for page 2. Because of this I would strongly recommend including all your code in a js file referenced in the headers of all your page, and NOT directly in script tags within your pages.
I have an asp.net mvc 4 with jquery-mobile app.
On one page (url: /StatementBatch ), I have a list of batches, which are simply links to the batch details page (url: /StetementBatch/Details/4 ).
<li>
<a href="/StatementBatch/Details/4">
<h3>January 2012</h3>
<div style="float: right; width: 30%;"><strong>Issued : </strong>1/10/2012 12:00:00 AM</div>
<div style="float: right; width: 30%;">Completed</div>
<p class="ui-li-aside"><strong>1277</strong></p>
</a>
</li>
The oddity is that once the link is clicked, and the details page renders, the browsers current url is now http://localhost:49457/StatementBatch#/StatementBatch/Details/4
What do I need to change in the app to get this behavior fixed?
My guess is that its some sort of ajax loading related problem, but my shared _Layout.cshtml file contains $.mobile.ajaxEnabled = false;, which I expected would kill all ajax loading, but I've obviously mis-interpreted that one.
Thanks!
I suspect this may be the answer
jQuery Mobile ajaxEnabled doesn't work?
Will test and see if I can make it work
moving the mobileinit binding to after jquery, but before jquery-mobile does the trick. This appears to be a bug in MVC4's (new) mobile web application template, which simply bundles all the scripts together
This fails....
<link href="#System.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/Content/css")" rel="stylesheet" type="text/css" />
<script src="#System.Web.Optimization.BundleTable.Bundles.ResolveBundleUrl("~/Scripts/js")"></script>
<script>
$(document).bind("mobileinit", function() {
// As of Beta 2, jQuery Mobile's Ajax navigation does not work in all cases (e.g.,
// when navigating from a mobile to a non-mobile page, or when clicking "back"
// after a form post), hence disabling it.
$.mobile.ajaxEnabled = false;
});
</script>
But this works....

That is the default behaviour if you use jQuery mobile. jQuery mobile will enable all your links to be ajaxified. That means it will load content of the linked page via ajax and update the url. If you want to disable a link to be ajaxified, you can add rel attribute with external as value
This will open without ajax
This will do a normal page opening so your urls will updated based on the new page.
Alternatively you can use data-ajax="false" as well
This link also will open without ajax
this link has more info about it http://jquerymobile.com/test/docs/pages/page-links.html
That is strange. If $.mobile.ajaxEnabled = false; is set then it should not generate ajax links. Please check whether your view is using some other master page which has got this setting enabled. Look for "_ViewStart.cshtml" under the corresponding view directory to see which master it is linked to.
In order to disable Ajax behavior for a particular hyperlink use data-ajax="false" attribute. Like below
<a href="/StatementBatch/Details/4" data-ajax="false">
<h3>January 2012</h3>
<div style="float: right; width: 30%;"><strong>Issued : </strong>1/10/2012 12:00:00 AM</div>
<div style="float: right; width: 30%;">Completed</div>
<p class="ui-li-aside"><strong>1277</strong></p>
