JQuery Mobile don't show progress bar when page load via Ajax - jquery-ui

I'm building an app utilizing JQuery Mobile in which I'm showing a progress bar to indicate to the user their progress based on the steps completed.
For the progress bar I'm utilizing JQuery UI which is simple to implement
<script>
$(document).ready(function(){
var currentStep = $("#formNumber").val(); //get the the current step from form
var totalSteps = 8;
var formProgress = 0;
// determine overall form progress after step is completed
if (currentStep >1) {
formProgress = (currentStep-1)/totalSteps*100;
}
// Set progress value
$("#progressbar").progressbar({value: formProgress});
$('#percentage').text(formProgress);
});// End function
</script>
However since the pages in JQuery Mobile are loaded via Ajax the progress bar does not show. I'm guessing it's because the "#progressbar" div is empty.
if the pages loads without Ajax it will show the progress bar. Any one knows how i can solve this by allowing the progress bar to show when the page loads via Ajax

Bind to pageinit not dom ready or in this case i bind to pageshow. In a JQM ajax app dom ready only happens once on the first page. So any new content brought into the dom doesn't get the benefit of the code you wrote. Also when the second page is brought into the dom. The first page doesn't go anywhere its just hidden. Because of this using the same id in every page causes problems. Get used to using classes instead. If you need to pick something out of the current page use the .ui-page-active class to help you select the appropriate element.
Something like $('.ui-page-active .formNumber') will select the correct input for you. So here is my revised first step according to the info you gave me.

Why select cannot be disabled/enabled in jquery mobile multi pages?

I have a mobile application which uses the multi-page template. In this application, I want to disable a select when the page is loaded and then enable it after a radio button is clicked. I've seen a strange thing: the disable/enable works (except its style) if the select is put on page 1 but it doesn't work if is put on other pages.
The following is the code:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Multi-page template</title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.1/jquery.mobile-1.2.1.min.css" />
<script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.1/jquery.mobile-1.2.1.min.js"></script>
<script src="mb.js" type="text/javascript" charset="utf-8" ></script>
</head>
<body>
<!-- Start of first page: #page1 -->
<div data-role="page" id="page1">
<div data-role="header">
<h1>Test </h1>
</div><!-- /header -->
<div data-role="content" >
<p>This is page One</p>
<form name="formC" id="formC" >
<label for="city">CITY: </label>
<select id="city" name="city" >
<option value="1">Sydney</option>
<option value="2">North Ryde</option>
<option value="others">Others</option>
</select>
Operations:
<input id="radioC1" name="city_type" type="radio" value="NO" >
<label for="radioC1"> 1 Disable city menu </label>
<input id="radioC2" name="city_type" type="radio" value="YES">
<label for="radioC2"> 2 Enable city menu </label>
</form>
</div><!-- /content -->
<div data-role="footer" data-theme="d">
<a data-role="button" href="#page1" > Page 1 </a>
<a data-role="button" href="#page2" > Page 2 </a>
</div><!-- /footer -->
</div><!-- /page one -->
<!-- Start of second page: #page2 -->
<div data-role="page" id="page2">
<div data-role="header">
<h1>Test</h1>
</div><!-- /header -->
<div data-role="content">
<p>This is page Two</p>
</div><!-- /content -->
<div data-role="footer">
<a data-role="button" href="#page1" > Page 1 </a>
<a data-role="button" href="#page2" > Page 2 </a>
</div><!-- /footer -->
</div><!-- /page two -->
</body>
</html>
The code of the javaScript mb.js is shown below:
$(document).ready(function(){
$("#city").prop("disabled", true);
$('input:radio[name="city_type"]').change (
function(){
if ($(this).is(':checked') && $(this).val() == 'YES') {
// alert("Click city_type, Enable");
$("#city").removeAttr('disabled');
// append goes here
} else if ($(this).is(':checked') && $(this).val() == 'NO') {
// alert("Click city_type, Disable");
$("#city").prop("disabled", true);
// append goes here
}
});
});
As seen from the code, the form which contains a select with id 'city' is put on page 1. In this case, the select is disabled at the beginning although its style still looks like enabled. I can enable/disable it by clicking the radio buttons. However after I've moved the form into page 2 from page 1, the select doesn't work! Although it is disabled at the beginning, I am not able to enable/disable it by clicking the radio buttons.
Really I don't know why. I have tried to use different versions of jquery and css but could not fix the problem. Is it a bug in jquery mobile multi-pages? Appreciated if some one can help to fix the problem.
I have had similar problems - without looking extremely close at your code, I notice that you're using $(document).ready() but you should be using:
$(document).delegate("#MyPageId", "pagebeforecreate", function () {
});
and
$(document).delegate("#MyPageId", "pageshow", function () {
})
instead. ( http://forum.jquery.com/topic/jquery-mobile-equivalent-of-document-ready )
Try moving your code into those areas and you'll have some success :)

jQuery mobile dialog not working with new page

I have a site built on jQuery Mobile and am trying to get our Terms of Service to open in a dialog.
TOS page is a full page itself (separate URL) and when I link with the dialog reference it simply opens as a new page.
My footer is
<div data-role="footer" data-theme="<?php echo $dataTheme ?>">
<div data-role="navbar">
<ul>
<li>Home</li>
<li><a rel="external" href="http://www.trackmaster.com">Full Site</a></li>
<li>Terms</li>
<li>My Account</li>
</ul>
</div>
</div>
and my tos.php page is (content stripped for convenience)

I have tried changing the data role of the TOS page to a dialog but that made no difference.
Am I not understanding the way dialog links can be used (from the docs I thought I could open one from any URL simply by defining the link as a dialog)
Site itself is http://mobiletest.trackmaster.com and it is the Terms link in the footer I am trying to get as a dialog (I don't want to include the content on every page, only when the user asks for it)
Any help appreciated (even pointing out the dumb things I am missing)
You are either missing a <div> or they don't match up; you've got two "content" divs.
EDIT: It's probably OK to have one within another, just noting that the <div data-role="page"> is never closed. Don't know if that makes any difference.
Found the issue.
The line in the header
$.mobile.ajaxEnabled = false;
I commented it out and the dialog link works as expected.
was the problem, I am testing it to see what else gets broken when I pull it out :-).
Data role for the TOS page is NOT relevant as loading it as a dialog automatically assigns the dialog data role

How to show a dialog with changePage function?

I'm trying to create a simple widget using jQuery mobile. I have a button, and when I click on that button, I want a dialog to appear that will display a date submission form. I defined a div in my html like this:
<div data-role="dialog" id="DatePage" >
<div data-role="content">
<form>
<input type="date" name="date" />
<input type="submit"/>
</form>
</div>
</div>
Now, in order to make this dialog appear when I click a button, I've been trying to use the following line of code:
$.mobile.changePage("#DatePage");
However, when I do this, nothing happens. I've tried adding other arguments and using different variations, but nothing works. From what I've read elsewhere, and from the examples I've seen, this line should show me the dialog, but it simply doesn't. What am I doing wrong?
use this snippet
<button onClick="$.mobile.changePage('#DatePage', {transition: 'pop', role: 'dialog'});">Open Dialog</button>
to open your dialog with a button, see working example
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Test</title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
</head>
<body>
<div data-role="page">
<div data-role="header">
<h1>Header</h1>
</div><!-- /header -->
<div data-role="content">
<button onClick="$.mobile.changePage('#DatePage', {transition: 'pop', role: 'dialog'});">Open Dialog</button>
</div>
</div><!-- /page -->
<div data-role="page" id="DatePage">
<div data-role="content">
<h1>My Dialog</h1>
<form>
<input type="date" name="date" />
<input type="submit"/>
<button data-rel="back">Close Dialog</button>
</form>
</div>
</div><!-- /page -->
</body>
</html>
In my final solution the dialog was triggered by the following code snippet:
$.mobile.changePage('#DatePage', {transition: 'pop'});
The problem with the dialog being shown only on the first click on the button appeared because the front page was never shown again after the dialog was shown the first time and any of the two button was clicked the dialog disappeared. The page could be seen because it was the dialog's background, but it was actually never there. In order to avoid the problem, I used the following code snippet:
<!-- The popup dialog for date selection -->
<div data-role="page" id="DatePage">
<div data-role="content">
<form id="DateSubmissionForm">
<input type="date" name="date" />
Submit
Cancel
</form>
</div>
</div>
The 'submit' and 'cancel' buttons are actually links back to the front page. With this code, the front page is really shown again and the button is again clickable.

jqm form submit on multipages

i have an issue with a form on a jquery mobile site with two or more pages.
one page contains a form and when clicking the submit button of this form, i want to submit the form data and then stay right on this page. so i added the id of that page to the form's action attribute. (<form action="#two">).
but unfortunately this doesn't seem to work. when submitting the form data, always the first page of the actual file is loaded, even if the browser's url seems right (the correct id was appended to it).
and it's getting even worse. because i added the id to the form's action attribute, jqm loads the first page of the file but apparently thinks to be on the second page, so the link pointing to the page with the form won't work anymore.
one thing resolved this issue: adding data-ajax="false" to the form element forces jqm to stop ajax-based page handling for this form and when clicking the submit button i end up on the right page, but i do not want to reload the entire page so that's no solution.
does anyone know what's going on here and has encountered the same issue? feel free to try the appended example, i hope someone can solve this.

Change your input submit tag to call a function.
<input type="submit" onclick="submitThis()" />
Add this logic to your submit function which will call the submit url through ajax and return false to avoid physically submitting form.
var submitThis = function() {
// get form data using jQuery, and call the link using $.ajax()
return false; // This will avoid submitting the page
}
--EDIT--
Instead or returning false, you can also use preventDefault() method
$("#submit").submit( function (e) {
e.preventDefault();
// do your task
});

Jquerymobile dialog using mobile.changepage doesn't work on second page

I have a dialog (not external html), which is displayed when I click on a button on the page, it works fine if the html containing the dialog is the first page to be accessed , but if that file is opened by clicking on an href from another page, the dialog doesn't show up when I click the button.
Here is the code for the page containing the dialog ... The alert in the click event of the button is showing up even when this is the not the first page to be accessed, but the dialog doesn't show up.

You use jQuery Mobile v1.0 but at the same time you pass incorrect arguments to $.mobile.changePage like if it were say v1.0 alpha. Not sure if it solves your problem but worth trying:
$.mobile.changePage('#successdiv', {
transition: 'pop',
reverse: false,
changeHash: true
});
When I jump from one jquery mobile page to another via a hrefs, I have to set the rel attribute to external, like this:
page2
dfsq is right, only the div[data-role="page"] is loaded when you link to this page from another page. I'd suggest moving the dialog into its own html file and opening it either via
open dialog
or
$.mobile.changePage('your_dialog.htm', {role: 'dialog', transition: 'pop'});
