I've been trying to get a script that inserts a div of text after the first and second paragraph of an article to work in jQueryMobile. It works on the first pageload, but on the second it loads the content twice, and the third time it's loaded three times, and so on.
The jQueryMobile libraries and my script is loaded in the head:
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script src="myscript.js">
<script src="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js"></script>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" />
Then I have
<body id="mobile">
<div id="wrapper" data-role="page">
And then the content of the page
My script is executed as documented on jquerymobile.com
$("#wrapper").live('pageinit', function() {
Am I missing something? Any help will be deeply appreciated.
try adding data-dom-cache="false" it should look like this
<body id="mobile">
<div id="wrapper" data-role="page" data-dom-cache="false">
As Clarence commented, a better solution is to move the <script> tag outside of the <div> with data-role="page"
<body id="mobile">
<div id="wrapper" data-role="page">
<!-- stuff -->
</div>
<script>
$("#wrapper").live('pageinit', function() {
// more stuff
});
</script>
</body>

i am not able to figure out what i am doing wrong ?, Any help would be appreciated.
You are including jQuery multiple times. Your bundle already included it, so you can remove this line in your layout:
<script src="~/Scripts/jquery-1.7.1.min.js"></script>
and these lines from your view:
<script src="~/Scripts/jquery-1.9.1.js"></script>
<script src="~/Scripts/moment.js"></script>
<script src="~/Scripts/bootstrap.js"></script>
<script src="~/Scripts/bootstrap-datetimepicker.min.js"></script>
This line in your Layout
#Scripts.Render("~/bundles/jquery")
is doing it all for you, because you added those scripts to that bundle.
Including the same script multiple times impacts negatively on performance, but wouldn't normally stop the code from working. However, in this case the different versions of jQuery that you've included are all different versions. I would check what is in your Scripts folder and see if it is up to date.
As an aside, it's also considered good practice to put styles (e.g. CSS) at the top of the page and scripts at the bottom, because that way the browser will load the page properly with styling, and not be slowed down by trying to load scripts halfway through (and if there's a problem with the script, the page still loads).
And as a final aside, you also look like you are a bit confused about the difference between .min.js and .js (I'm extrapolating from the fact you sometimes use the min version and sometimes don't; if you know all this already please excuse me!). The .min.js files are a minimised version (variable names as short as possible, comments deleted, whitespace reduced to minimum) that can be sent to the server. You may already have something like this
#if DEBUG
BundleTable.EnableOptimizations = false;
#else
// note: overrides compilation debug="true" in Web.config
BundleTable.EnableOptimizations = true;
#endif
in your Bundle.Config file. If not, it's handy to add because it means that the release version has the best performance (.min.js files) but the debug version is more human-readable (normal .js files) to help you debug it.
I embedded phoneGap in my UIWebView, referenced to this doc:
http://docs.phonegap.com/en/2.2.0/guide_cordova-webview_ios.md.html#Embedding%20Cordova%20WebView%20on%20iOS
And in the index.html, I write this sample code:
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
alert(“jquery loaded”);
});
</script>
</head>
<body>
<h2>This is a heading</h2>
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
<button>Click me</button>
</body>
after the webview loaded, the "body" can be shown, but the alert can't be pop out. So the jquery.js is not loaded? Or something else is wrong?
Edit:
I added "http:" to the src, but not work.
Thanks!
change
alert(“jquery loaded”);
to
alert("jquery loaded");
or
alert('jquery loaded');
Add http or https to your code
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
The above should work for you.
Did you add the Cordova file?
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript" src="./cordova-2.3.0.js"></script>
<script>
$(document).ready(function() {
alert(“jquery loaded”);
});
</script>
</head>
<body>
<h2>This is a heading</h2>
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
<button>Click me</button>
</body>
</html>
Also as much as phonegap uses HTML 5 it still requires a bit different style of writing your code. Everypage you make should all be in the same index page because Cordova loads at startup in your project. If you navigate away from the page Cordova needs to reload.
Did you copy jquery file at www forder (www/jquery.js). I use jquery too, mine is www/js/jquery.js
Try this!!!
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!
// page number 1
<header>
includes and stuff
<header>
<body>
<div data-role="page" data-theme="a" id="dashboardPage">
$('#dashboardPage').live('pageinit',function() {

// somewhere in here a page transition to anotherPage.html (not necessarily the id of the new page in the <div data-role-"page data-theme...> declaration
$.mobile.changePage("anotherPage.html",{transition : "slide"});

<!-- END - BASIC INCLUDES -->

<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

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'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'm trying to use JQueryMobile for an POC and it seems even though I use #using (Html.BeginForm()) instead of #using (Ajax.BeginForm()), ajax is enabled by default. It is being injected from one of the script files [ ~/Scripts/jquery.mobile-1.0a2.js ].
So what I want is to simply disable the Ajax for certain forms and do full form posts. This might be pretty abvious, but i simply cant get my head around it.
Any help is appreciated.

You have to set up the jquery mobile framework correctly to disable its auto - ajax
Here it's documented:
http://jquerymobile.com/demos/1.0a3/#docs/api/globalconfig.html
You could do something like this.
<html lang="en-us">
<head>
<title>#ViewBag.Title</title>
<link href="http://code.jquery.com/mobile/1.0a3/jquery.mobile-1.0a3.min.css" rel="stylesheet" type="text/css" />
<link href="#Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<script src="#Url.Content("~/Scripts/jquery-1.5.min.js")" type="text/javascript"></script>
<script language="javascript" type="text/javascript">
$(document).bind("mobileinit", function () {
$.mobile.ajaxFormsEnabled = #ViewBag.EnableAjax;
});
</script>
<script src="http://code.jquery.com/mobile/1.0a3/jquery.mobile-1.0a3.min.js" type="text/javascript"></script>
</head>
<body>
<div data-role="page" data-cache="never">
<div data-role="header">
<h1>#ViewBag.HeaderString</h1>
</div>
<div data-role="content">
#RenderBody()
</div>
<div data-role="footer">
<h1>HTDE</h1>
</div>
</div>
</body>
</html>
Just add the following line to your page, obviously you have too add this under the document.Ready() function:
$.mobile.ajaxEnabled = false;
Note: If you are using Jquery Mobile beta, the configuration parameter for disabling ajax has changed.
http://jquerymobile.com/blog/2011/06/20/jquery-mobile-beta-1-released/
"Use ajaxEnabled to globally set auto-ajax handling."
Here's a link to the documentation for beta configs:
http://jquerymobile.com/demos/1.0b2/#/demos/1.0b2/docs/api/globalconfig.html
It took me way to long to figure this one out.
there is an easier way.. just figured it out from JqueryMobile documentation
http://jquerymobile.com/demos/1.0a3/#docs/api/globalconfig.html
all you have to do is,
ajaxFormsEnabled :false
