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 :)

I am trying to create a jQuerymobile app with a Nav Bar with Multiple Pages in single index.html. I am using the template Multi-page template structure
Unfortunately, I cannot get the nav bar to show different pages. Here is my code:
I did also use a script 'pageLoader.js' to force loading the pages. But that does not work either. Here is my pageLoader.js:

I also tried to use a script to enforce change of pages. I used the pageLoader.js script with following content:
$(document).on("pageshow", function(){
if($('.ui-page-active').attr('id') === 'postPage'){
$.mobile.changePage("#postPage");
} else if ($('.ui-page-active').attr('id') === 'getPage'){
$.mobile.changePage("#getPage");
}
});
Any help would be greatly appreciated.
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.
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.

If you interested I made a sample for you to look at. http://starwebservices.net/so/
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'});
I am very new to jquery-mobile. Could someone please help with the following problem regarding a multi-page app?
My app has two pages, split into two different files - index2_1.html and index2_2.html given below. When I use $.mobile.changePage("index2_2.html", "slide"); to change to the second page, none of the events in the second page get bound. Actually, none of the Javascript on the second page gets executed. However, if move to the second page using the link
Link to 2nd page that works1
it works fine.
Could someone please tell me what I am doing wrong here?
Thanks,
Dilip

In contrast to Pravat Maskey's answer, it's possible (and dependent on the use case also intended) to have seperate HTML files. Just imagine a huge application with lots of pages, it would be counterintuitive to load everything up front.
I think the problem you are having is the placement of the JavaScript code. I would try including the page specific code (the script tag and everything it contains) in the page section, just above the closing div of the page. For more details, take a look at this guide: http://jqx.ca/nav/, and check the section "Scripts in jQuery Mobile Pages".
By having the tag in the body, your code is executed once when the sub-page is created for the first time. For your case this should work, as you are binding an event to a DOM node, which only needs to run once.
You could also try registering your code with the pagebeforeshow event if you want to run it everytime the page is shown.
