I must be missing something very basic in the CSS. My jQuery anchor button is functional, but it's rendering as a simple underlined label, not asa rounded-corner UI button. I would be grateful if someone could point out the error in this simple example.
Thanks

You need to actually make it a button using .button(), like this:
$(function() {
$(".test a").button();
});
You can see the jQuery UI demos here and a demo of your markup working here.
You need to add the proper class to the link, using jQuery or otherwise.
Try:
Button
You do not need to make it a button you just need
$(".test a").click(function(){showIntro();return false;});
What you are trying to do with your selector passing the second paramater is the Scope.
The second paramater is not mean to be a string (selector) it should be a jQuery Object.
So if you wanted to do it your way your would have to say
var test = $('.test');
$('a',test).click...
But the 1st method is prefered over doing it this way.
Sorry to be providing an answer, if not "the" answer, to my own question, but I have discovered a clue as to what's going on, if not the ultimate cause of the behavior. Below is code cut and pasted from the Button example on the jQuery website; take it to jsFiddle and run it: it works. But if you remove this line relating to the input-button:
$("button, input:submit, a", ".demo").button();
then the anchor-button fails to render properly. Why is the anchor-element's rendering dependent on the existence of the input-button?
<script type="text/javascript">
$(function() {
$("button, input:submit, a", ".demo").button();
$("a", ".demo").click(function() { return false; });
});
</script>
<style>
</style>
<div class="demo">
<button>A button element</button>
<input type="submit" value="A submit button">
An anchor
</div><!-- End demo -->

I am trying angular.dart and saw that its slow. When am html page is loaded containing angular, angular directive is seen first, which are then converted appropriately. Shouldn't it be converted instantaneously and the user should not see whether we are using angular ?
<!DOCTYPE html>
<html ng-app>
<head>
<title>Hello, World!</title>
</head>
<body>
<h3>Hello {{name}}!</h3>
name: <input type="text" ng-model="name">
<script type="application/dart" src="main.dart"></script>
<script type="text/javascript" src="packages/browser/dart.js"></script>
</body>
</html>
Surround {{name}} with a tag having class="ng-cloak". I used span tag. Keep it hidden by specifying css rule .ng-cloak{ display:none; }.
When angular is loaded, it will remove class="ng-cloak" from the span tag and everything will work as expected.
<!DOCTYPE html>
<html ng-app>
<head>
<title>Hello, World!</title>
<style>
.ng-cloak{ display:none;}
</style>
</head>
<body>
<h3>Hello <span class="ng-cloak">{{name}}</span>!</h3>
name: <input type="text" ng-model="name">
<script type="application/dart" src="main.dart"></script>
</body>
</html>
An alternative way is to use ng-bind as demonstrated in this youtube video: AngularJS MTV Meetup: Best Practices (2012/12/11) (after about 12 minutes)
Quoted from the API doc of NgBindDirective class
Typically, you don't use ngBind directly, but instead you use the
double curly markup like {{ expression }} which is similar but less
verbose.
It is preferrable to use ngBind instead of {{ expression }} when a
template is momentarily displayed by the browser in its raw state
before Angular compiles it. Since ngBind is an element attribute, it
makes the bindings invisible to the user while the page is loading.
This way you can display default content that get's replaced when Angular is ready
instead of showing a blank page or a progress icon.
I have an issue with vclick (or click) events when fired.
This is my html code:
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=no">
<title>Document</title>
<link rel="stylesheet" href="css/jquery.mobile-1.3.1.css">
<link rel="stylesheet" href="css/estilo.css">
<script src="js/cordova-2.6.0.js"></script>
<script src="js/jquery-2.0.0.js"></script>
<script src="js/functions.js"></script>
<script src="js/jquery.mobile-1.3.1.js"></script>
</head>
<body>
<div data-role="page" id="page">
<div data-role="header" position="fixed">
<h1>Data</h1>
</div>
<div data-role="content">
<div id="btn_comentar">
</div>
</div>
</div>
</body>
</html>
And this is my functions.js
$(document ).bind("mobileinit", function(){
$(document).bind("pageinit",function(){
$("#btn_comentar").bind("vclick",function(e){
console.log(e.isDefaultPrevented());
console.log(e.result);
console.log(e.relatedTarget);
alert("buttooon");
list_comments();
});
});
}
When I click my #btn_comentar, the data that I want to retrieve from function list_comments (sending via ajax) is duplicated; I realized that it was sending twice, and finally that it was something about when I clicked on my button.
This is the output from the console (twice):
false
undefined
null
and also the alert message box (twice) "buttoon";
I have tried some solutions like:
jQuery Mobile : replace click event by vclick event
but without success, please need some help
This is my new code and how it is now working, but it seems that without jQuery Mobile's default configuration

//$.mobile.allowCrossDomainPages = true;
});
functions.js
$(document).on("ready",function(){

list_comments();
});
});
According to docs,
These enhancements are applied based on jQuery Mobile's default configuration, which is designed to work with common scenarios, but may or may not match your particular needs. Fortunately, these settings are easy to configure using the mobileinit event.
So that's what you need to use mobileinit for. For setting defaults like this :
$(document).bind('mobileinit', function(){
$.mobile.defaultTransition = 'slideup';
});
If my understanding is right, mobileinit is included/fired before jQuery Mobile's js is included. Assuming you done that, your script order must look like this :
<script src="jquery.js"></script>
<script src="custom-scripting.js"></script> <!-- This script must have mobileinit -->
<script src="jquery-mobile.js"></script>
At this point of time (when custom-scripting.js is loaded), pageinit wouldnt be defined.
It would be wise to add your pageinit event AFTER jQM script.
<script src="jquery.js"></script>
<script src="custom-scripting.js"></script> <!-- This script must have mobileinit -->
<script src="jquery-mobile.js"></script>
<script>
$(document).bind("pageinit", function(){
$(document).bind("vclick", "#btn_comentar" ,function(e){
console.log(e.isDefaultPrevented());
console.log(e.result);
console.log(e.relatedTarget);
alert("buttooon");
list_comments();
});
});
</script>
use once on pageinit:
$(document).on('pageinit') {
$("#btn_comentar").on("vclick",function(e){
console.log(e.isDefaultPrevented());
console.log(e.result);
console.log(e.relatedTarget);
alert("buttooon");
list_comments();
});
}
this should work
Another cause of double-vclicks I've encountered is due to Chromium synthesizing both touch events in addition to mouse events. I confirmed this cause by running the app in desktop Chrome's developer "device mode" (where the mouse cursor changes into a circle), confirming the problem exists, then toggling off device mode, and confirming the problem is "fixed".
jblas discusses it, partial excerpt:
Note that vclick does NOT suppress the synthesized mouse/click events that are generated by the browser because it does not know what context it is being used in, AND form input elements require the mouse/click events to function normally.
If you use a joystick or mouse (desktop), the alert will fire on the normal mouse click event.
If you want to suppress the click event while using touch, you have to call event.preventDefault() in your vclick handler. This will queue the request to kill the click event that follows but due to the differences in the way device vendors implement their events, and some bugs within different android OS versions, this turns out to be very hard to do. We try a couple of methods to figure out whether or not to kill a click event ... one is based on the element the touch event was triggered, on, and another is the position of the touch event. This is necessary because The browser does not necessarily dispatch the mouse events to the same element that it used for the touch event.
This seems like it would have a really obvious answer, however I cannot get a simple checkbox to uncheck with JQuery once I add Jquery Mobile.
Here is some very simple code as an illustration:
<html>
<head>
<title>Untitled</title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.css" />
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.js"></script>
<script>
jQuery(function () {
jQuery('#a').change(function () {
if (jQuery(this).is(':checked')) {
jQuery('#b').removeAttr('checked');
}
});
jQuery('#b').change(function () {
if (jQuery(this).is(':checked')) {
jQuery('#a').removeAttr('checked');
}
});
});
</script>
</head>
<body>
<input type="checkbox" id="a"><label for="a">AAAA</label>
<input type="checkbox" id="b"><label for="b">BBBB</label>
</body>
</html>
This is a simple bit of code. When Checkbox 'A' gets checked, it should uncheck checkbox 'B', and vise verse. However it doesn't, and no error is written to the console.
This is using the standard version of Jquery & Jquery Mobile, linked directly to their site
If I remove the Jquery Mobile elements, by removing the following lines, then it works fine
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.css" />
<script src="http://code.jquery.com/mobile/1.3.1/jquery.mobile-1.3.1.min.js"></script>
Can anyone please enlighten me as to where I am going wrong, since this seems so simple yet I'm at an absolute loss as to what is going on.
Many thanks
Because you need to use .prop and then re-apply styles using .checkboxradio('refresh').
Check
$('selector').prop('checked', true).checkboxradio('refresh');
Uncheck
$('selector').prop('checked', false).checkboxradio('refresh');
Ok so im expanding my existing MVC4 app into a mobile app.
Totally new to jquery mobile and im having so many issues with this in MVC.
Layout pages (MVC) and jquery mobile are a nightmare to work with or is it just me?
So im simply trying to show jquery ui datepicker in my page, it does not show!
I have to do a reload of the page for it to show, why???
Ok Layout page
#{
Layout = null;
}
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" >
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="viewport" content="width=device-width, initial-scale=1">
<title></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-1.8.0.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
<script src="http://code.jquery.com/ui/1.10.0/jquery-ui.js"></script>
</head>
<body>
#RenderBody();
</body>
</html>
and now the view
#{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_AppLayout.Iphone.cshtml";
}
<script>
$(function() {
$( "#datepicker" ).datepicker();
});
</script>
#using (Html.BeginForm())
{
<div data-role="page" id="pageAccount">
<div data-role="content">
<div id="datepicker"></div>
</div>
</div>
}
Any ideas why the page shows, but no datepicker (I have to reload the page for it to show)?
Solution :
This should be changed:
$(function() {
$( "#datepicker" ).datepicker();
});
to this:
$(document).on('pageshow', '#pageAccount', function(){
$( "#datepicker" ).datepicker();
});
To make a story short. jQuery Mobile should not be used with classic DOM ready jQuery functions. Instead jQuery Mobile is providing us with page events. If you want to find out more about jQuery mobile page events and how they work take a look at this ARTICLE, to make it transparent it is my personal blog. Or you can take a look HERE.
Edit :
Here's a working example:
Change positions of
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
<script src="http://code.jquery.com/ui/1.10.0/jquery-ui.js"></script>
into:
<script src="http://code.jquery.com/ui/1.10.0/jquery-ui.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
jQuery Mobile should always load last when used with jQuery UI.
Also you have forgot jQuery UI CSS, you will find datepicker without its CSS formatting.
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
