I am learning a JQuery tutorial where I am intended to display a JQuery button with primary and secondary icons. The instructor's button looks like this:
The same code for me displays a button like this:
My code:
<!Doctype HTML>
<html>
<head>
<meta charset="utf-8">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<link rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/themes/smoothness/jquery-ui.css">
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js"></script>
</head>
<body>
<button id="button1">Button 1</button>
<script>
$('#button1').button({
icons: {
primary: 'ui-icon-mail-closed',
secondary: 'ui-icon-caret-1-e'
}
})
</script>
</body>
</html>
Now when I comment out the primary: '...' option, I can see the secondary button, but not both. Has JQueryUI changed? How can I show 2 icons on the button like the instructor's?
Note: The button widget was rewritten in 1.12. Some options changed, you can find documentation for the old options in the 1.11 button docs. This widget used to bundle support for inputs of type radio and checkbox, this is now deprecated, use the checkboxradio widget instead. It also used to bundle the buttonset widget, this is also deprecated, use the controlgroup widget instead.
So the Quick Fix is to use older Library: 1.11.4. Example:
$(function() {
$('#button1').button({
icons: {
primary: 'ui-icon-mail-closed',
secondary: 'ui-icon-caret-1-e'
}
});
});
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-3.3.1.js"></script>
<script src="https://code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
<button id="button1">Button 1</button>
This works.
The other method would be to add the element manually or use Controlgroup.

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

$(document ).bind("mobileinit", function(){
//$.mobile.allowCrossDomainPages = true;
});
functions.js
$(document).on("ready",function(){
$("#btn_comentar").bind("vclick",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');
I have this simple code, like that on the official site.

Obviously in the same folder I've moved the interested files and all works ok.
But the layout is awful, because sure miss something.
My output is this:

How can I solve this problem?
Thank you.
I dare say it's the style file: you probably have an incorrect path for the file or the file is corrupted. See the following two examples:
without css: http://jsfiddle.net/william/5Xa8f
with css: http://jsfiddle.net/william/5Xa8f/2/
To confirm it is the problem, simply replace jquery.ui.all.css with http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/themes/smoothness/jquery-ui.css, and see if the problem is fixed.
Why the following code doesn't work? (if I change remote source there to local, then it works well)
<!DOCTYPE html>
<html>
<head>
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script>
$(document).ready(function() {
$("input#autocomplete").autocomplete({
source: "http://jqueryui.com/demos/autocomplete/search.php",
minLength: 2,
select: function( event, ui ) {
}
});
});
</script>
<style>
.ui-autocomplete-loading { background: white url('http://jqueryui.com/demos/autocomplete/images/ui-anim_basic_16x16.gif') right center no-repeat; }
</style>
</head>
<body style="font-size:62.5%;">
<input id="autocomplete" />
</body>
</html>
same origin policy as the source requires a script from another site to be run.
http://en.wikipedia.org/wiki/Same_origin_policy
You could change the source to use a jquery ajax call to another site which can return jsonp.
See this for an example: http://jqueryui.com/demos/autocomplete/#remote-jsonp
or ensure that the source url given returns jsonp.
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 -->
