I'm currently building a mobile site for iPad using jquery mobile and ASP.NET MVC 4. I have a dynamically created listview that is displaying search results. I want the user to be able to click on an item in the listview and have the text from that particular list item appear in a textbox that is also in the view.
I can get this to work in Safari on my desktop machine, but it will not work on an iPad.
For the sake of simplicity and to attempt to narrow down the problem, I hard-coded a simple little listview in my View. The results were the same. Works on desktop in Safari, but not on iPad.
Here is the very simplified VIEW code that works in Safari on desktop (Please note that _Header is a separate, partial View):
#section Header
{
<script type="text/javascript">
$('#testJs li').on('click', (function () {
var results = $.trim($(this).text());
$('#testText').val(results);
}));
</script>
#{ Html.RenderPartial("_Header"); }
}
#section Content
{
<input type="text" id="testText">
<ul id="testJs" data-role="listview" data-inset="true" data-theme="c">
<li id="task400" class="tasks">Test task 400</li>
<li id="task295" class="tasks">Test task 295</li>
</ul>
}
Please note that I have tried changing 'click' to 'tap' (see below) with no success. It still doesn't work on iPad.
<script type="text/javascript">
$('#testJs li').on('tap', (function () {
var results = $.trim($(this).text());
$('#testText').val(results);
}));
</script>
I've also tried using the following with the same results. Still doesn't work on the iPad.
<script type="text/javascript">
$('#testJs').delegate('li', 'tap', function () {
var results = $.trim($(this).text());
$('#testText').val(results);
});
</script>
I do wonder if this has something to do with our use of layout pages. We have slightly different layout pages, depending on if the site is being rendered on a mobile device or not.
Mobile Layout View:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>#ViewBag.Title</title>
<meta name="viewport" content="width=device-width, initial-scale=1" />
#Scripts.Render("~/bundles/jquery", "~/bundles/jquerymobile")
#Scripts.Render("~/bundles/modernizr")
#Styles.Render("~/Content/mobileCss", "~/Content/css")
<script type="text/javascript">
$(document).ready(function () {
$.mobile.ajaxEnabled = false;
});
</script>
</head>
<body>
<div data-role="page" data-theme="b">
<div data-role="header" data-position="fixed" data-tap-toggle="false">
#if (IsSectionDefined("Header")) {
#RenderSection("Header", false) }
else { <h1>#ViewBag.Title</h1> }
</div>
<div data-role="content">
#RenderSection("Content")
</div>
</div>
</body>
</html>
Desktop Layout View:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>#ViewBag.Title</title>
<link href="~/favicon.ico" rel="shortcut icon" type="image/x-icon" />
#Scripts.Render("~/bundles/jquery", "~/bundles/jquerymobile")
#Scripts.Render("~/bundles/modernizr")
#Styles.Render("~/Content/mobilecss", "~/Content/css")
</head>
<body>
<div data-role="page" data-theme="b">
<div data-role="header" data-position="fixed" data-tap-toggle="false">
#if (IsSectionDefined("Header")) {
#RenderSection("Header") }
else { <h1>#ViewBag.Title</h1> }
</div>
<div data-role="content">
#RenderSection("Content")
</div>
</div>
</body>
</html>
I've been stuck on this for a few days, so any help would be appreciated. Everything I try works on my desktop, but not on an iPad - which is where I actually need it to function.
Thanks!
Did you try using bind on your testJs li? I'd bind a tapHandler like below:
<script>
$(function(){
$( "#testJs li" ).bind( "tap", tHandler );
function tHandler( event ){
var results = $.trim($(this).text());
$("#testText").val(results);
}
});
</script>
or with on like this should work:
$('#testJs').on('tap', 'li', function (event) {
var results = $.trim($(this).text());
$("#testText").val(results);
console.log('this should work')
}
Also used double quotes on top example but that shouldn't make a difference I don't think. If it doesn't then make sure you .js references are correct, and use firebug in firefox to debug for any straggling errors.

I have a page called index.html, when I click the link in index html it will navigate to the another page which has Listview populated with data taken from Server. This Works without any error.
However, when I click the back button of current page, I will be directed to the previous page.
My question is, it refreshes current page and then go back to the previous page.
I need to prevent this.

I have built a jQuery Mobile application, but I have one issue I don't understand.
I am using the multi-page functionality, but when you are in a page and you change the screen orientation, it jumps back to the start page. I do not understand how to stay on the current page when changing orientation.
I have tried this:
$(window).bind("orientationchange", function (e, ui)
{
var sPage ="#"+$.mobile.activePage.attr("id");
$.mobile.changePage(sPage);
alert(sPage);
});
The alert() showed the correct page where I want to stay.
Below is an example how is made the multipage. If i select the option 'Instellingen',
This pages showed. But when i change the smartphone orientation, it jumps back to the menu.

I had the exact same issue for months, until today I added the screenSize parameter to the android manifest, as follows:
android:configChanges="orientation|screenSize|keyboardHidden"
Hope that helps!
I've tried adding swipe-support to SudoSlider via Jquery Mobile, but so far it doesn't seem to work. Both on the ipad and the iphone nothing happens when tried swiping.
Minimal working example of my page:

<li class="page" id="projects"></li>
<li class="page" id="contact"></li>
</ul>
</div>
</div>
<script type="text/javascript" >
$(document).ready(function(){
var sudoSlider = $("#pages").sudoSlider({
history: true,
prevNext: false,
continuous: true,
customLink: 'a.slide-controller',
numericText:['home', 'mission', 'about', 'services', 'portfolio', 'contact']
});
$(document).keyup(function(e) {
switch(e.keyCode) {
case 37 : sudoSlider.goToSlide("prev"); break;
case 39 : sudoSlider.goToSlide("next"); break;
}
$("#pages").swiperight(function() {
sudoSlider.goToSlide("next");
});
$("#pages").swipeleft(function() {
sudoSlider.goToSlide("prev");
});
});
});
</script>
</body>
</html>
Although I am not an jquery mobile expert, I think you need to bind the swipe events to the pages, like $("#pages").bind("swipeleft", function() {...});
Also you should take a look at the documentation to use $(document).bind('pageinit') instead of $(document).ready()
Visit http://jquerymobile.com/demos/1.2.0/docs/api/events.html and take a look at the first yellow box; the swipe events are also explained there below.
When run, if I click the link at the bottom of the index page to get to the map page, I see the map briefly, filling a quarter of the screen, before it vanishes. What am I doing wrong?
Here is the code for the index page, which creates the map page:

The following code works: jsfiddle
I took your code, simplified it (using a single page template instead of the multi page one, but just to make it easier for jsfiddle) and moved all scripts inside the head.
Also be careful with phonegap, you should handle the onDeviceReady event, and not the body onload event. Even then there's a different method there to check if you're online.
Stripped down code shows that I can change an attribute, in this case data-split-icon, but cannot get a refresh. Console.log show it has changed, so does the element view in chrome developer tools.
http://jsfiddle.net/mckennatim/MQ9rj/ 'Get' button simulates a programmatically created list. 'Change' button simulates changing an attribute.
Refresh, listview, trigger, create, pagecreate I try all combinations. Nothing works

Looks like jQM also adds some markup on the children span tags, try something like this
http://jsfiddle.net/phillpafford/MQ9rj/18/
JS
$('#change').click(function() {
console.log($('ul').attr('data-split-icon'));
$('#list').attr('data-split-icon', 'info'); //jqmData doesn't work either
console.log($('ul').attr('data-split-icon'));
$("[data-icon=gear]").each(function() {
var $this = $(this);
$this.attr('data-icon','info');
$this.children().children().removeClass('ui-icon-gear').addClass('ui-icon-info');
});
$('#list').listview('refresh',true);
return false;
});
