jQuery / jQuery UI - $("a").live("click", ...) not working for tabs - jquery-ui

So I have some jQuery UI tabs. The source code is as follows:
HTML:
<div class="tabs">
<ul>
<li>Ranges</li>
<li>Collections</li>
<li>Designs</li>
</ul>
<div id="ranges"></div>
<div id="collections"></div>
<div id="designs"></div>
</div>
jQuery:
$(document).ready(function() {
$(".tabs").tabs();
});
My problem is that I am trying to make each tab load a page into the content panel on click of the relevant link. To start with I am just trying to set the html of all the panels on clicking a link. From the code below, if I use method 1, it works for all links. However if I use method 2 it doesn't - but only for the links in the tabs (i.e. the labels you click to select a tab).
Method 1 (works for all links all the time, but would not be applied to links which are added after this is called):
$("a").click(function () {
$("#ranges, #collections, #designs").html("clicked");
});
Method 2 (works for all links which are not "tabified"):
$("a").live("click", function () {
$("#ranges, #collections, #designs").html("clicked");
});
Does anyone know why it is behaving like this? I would really like to get method 2 working properly as there may well be links which I need to add click events to which are added after the page is originally loaded.
Thanks in advance,
Richard
PS yes the function calls for .live and .click are both in the $(document).ready() function, before anyone says that that may be the problem - otherwise it wouldn't work at all..
Edit:
The solution I came up with involves an extra attribute in the anchors (data-url) and the following code (which outputs a 404 not found error if the page cannot be loaded). I aim to expand this over the next few weeks / months to be a lot more powerful.
$(".tabs").tabs({
select: function (event, ui) {
$(ui.panel).load($(ui.tab).attr("data-url"), function (responseText, textStatus, XMLHttpRequest) {
switch (XMLHttpRequest.status) {
case 200: break;
case 404:
$(ui.panel).html("<p>The requested page (" + $(ui.tab).attr("data-url") + ") could not be found.</p>");
break;
default:
$(ui.panel).html("<p title='Status: " + XMLHttpRequest.status + "; " + XMLHttpRequest.statusText + "'>An unknown error has occurred.</p>");
break;
};
});
}
});

I don't know if I understand what you are going for but basically you want to do something once a tab is clicked?
Here's the docs for setting up a callback function for selecting a tab.
EDIT: Don't know if that link is working correctly, you want to look at select under Events. But basically it is:
$("#tabs").tabs({
select: function(event, ui) { ... }
});
Where ui has information on the tab that was clicked.

jQuery UI tabs has an outstanding issue where return false; is used instead of event.preventDefault();. This effectively prevents event bubbling which live depends on. This is scheduled to be fixed with jQuery UI 1.9 but in the meantime the best approach is use the built in select event as suggested by #rolfwaffle.

Maybe the tabs() plugin that you are using is calling event.preventDefault(); (Reference) once it has created it's tabs.
Then it captures the click event and the bubbling stops, so it doesn't invoke your click-function. In jQuery this is done with
$(element).click(function(){
// Do stuff, then
return false; // Cancels the event
});
You'd have to alter the tabs() plugin code and remove this return false; statement, OR if you are lucky, the plugin might have an option to disable that behavior.
EDIT: Now I see you're using jQuery UI. Then you should check the documentation there, since it is an awesome plugin, it will do anything you want if you do the html right and pass it the right options.

jQuery mobile listview multiple click event

I fill list dynamically, and after that on click I have multiple calls of event. 1st time it is repeated 1 time, 2nd time 2 times, 3rd time 3 times, etc...
First, more about this problem can be found in my other answer: jQuery Mobile: document ready vs page events
Prevent multiple event binding/triggering
Because of interesting jQM loading architecture, multiple event triggering is a constant problem. For example, take a look at this code snipet:
$(document).on('pagebeforeshow','#index' ,function(e,data){
$(document).on('click', '#test-button',function(e) {
alert('Button click');
});
});
Working jsFiddle example: http://jsfiddle.net/Gajotres/CCfL4/
Each time you visit page #index click event will is going to be bound to button #test-button. There are few ways to prevent this problem:
Solution 1:
Remove event before you bind it:
$('#index').live('pagebeforeshow',function(e,data){
$('#test-button').die().live('click', function(e) {
alert('Button click');
});
});
Working jsFiddle example: http://jsfiddle.net/Gajotres/K8YmG/
In case you have different events bound to an object:
$('#index').live('pagebeforeshow',function(e,data){
$('#test-button').die('click').live('click', function(e) {
alert('Button click');
});
});
Solution 2:
Use a jQuery Filter selector, like this:
$('#carousel div:Event(!click)').each(function(){
//If click is not bind to #carousel div do something
});
Because event filter is not a part of official jQuery framework it can be found here: http://www.codenothing.com/archives/2009/event-filter/
In a nutshell, if speed is your main concern then Solution 2 is much better then Solution 1.
Solution 3:
A new one, probably an easiest of them all.
$(document).on('pagebeforeshow', '#index', function(){
$(document).on('click', '#test-button',function(e) {
if(e.handled !== true) // This will prevent event triggering more then once
{
alert('Clicked');
e.handled = true;
}
});
});

mobile.changepage requiring page refresh

I'm using $.mobile.ChangePage() to navigate from one HTML page to another. But the contents of the page is not changing. while doing so the page URL changes but the new page is not loaded. it requires to be refreshed to load.
you should use JavaScript function to change the page..using
window.location = 'your page ';
hope it will resolve your problem !
In the code that you provided in the comments above, you are likely getting an error stating that next_page is not defined. Given that you are dealing with jQuery Mobile, try assigning the click handler slightly differently:
Change the definition of the link to something like this:
<a id="btnNextPage" href="#" >Details</a>
You don't have to give it an id - you could just use selectors to identify the link in the following javascript:
// the event handler
function next_page() {
$.mobile.changePage("http://www.google.com", {transition:"slide"});
}
// assign the click event when the DOM is ready
$(function() {
$("#btnNextPage").click ( next_page );
});

Is there any way to control the layout of the close button on a jQuery Mobile custom select menu?

I have a custom select menu (multiple) defined as follows:
<select name="DanceStyles" id="DanceStyles" multiple="multiple" data-native-menu="false">
Everything works fine except that I want to move the header's button icon over to the right AND display the Close text. (I have found some mobile users have a problem either realising what the X icon is for or they have trouble clicking it, so I want it on the right with the word 'Close' making too big to miss.) There don't seem to be any options for doing that on the select since its options apply to the select bar itself.
I have tried intercepting the create event and in there, finding the button anchor and adding a create handler for that, doing something like this (I have tried several variations, as you can see by the commenting out):
$('#search').live('pagecreate', function (event) {
$("#DanceStyles").selectmenu({
create: function (event, ui) {
$('ul#DanceStyles-menu').prev().find('a.ui-btn').button({
create: function (event, ui) {
var $btn = $(this);
$btn.attr('class', $btn.attr('class').replace('ui-btn-left', 'ui-btn-right'));
$btn.attr('class', $btn.attr('class').replace('ui-btn-icon-notext', 'ui-btn-icon-left'));
// $(this).button({ iconpos: 'right' });
// $btn.attr('class', $btn.attr('class').replace('ui-btn-icon-notext', 'ui-btn-icon-left'));
// // $btn.attr('data-iconpos', 'left');
$(this).button('refresh');
}
});
}
});
});
So I have tried resetting the button options and calling refresh (didn't work), and changing the CSS. Neither worked and I got weird formatting issues with the close icon having a line break.
Anyone know the right way to do this?
I got this to work cleanly after looking at the source code for the selectmenu plugin. It is not in fact using a button; the anchor tag is the source for the buttonMarkup plugin, which has already been created (natch) before the Create event fires.
This means that the markup has already been created. My first attempt (see my question) where I try to mangle the existing markup is too messy. It is cleaner and more reliable to remove the buttonMarkup and recreate it with my desired options. Note that the '#search' selector is the id of the JQ page-div, and '#DanceStyles' is the id of my native select element. I could see the latter being used for the id of the menu, which is why I select it first and navigate back up and down to the anchor; I couldn't see any other reliable way to get to the anchor.
$('#search').live('pagecreate', function (event) {
$("#DanceStyles").selectmenu({
create: function (event, ui) {
$('ul#DanceStyles-menu').prev().find('a.ui-btn')
.empty()
.text('Done')
.attr('class', 'ui-btn-right')
.attr("data-" + $.mobile.ns + "iconpos", '')
.attr("data-" + $.mobile.ns + "icon", '')
.attr("title", 'Done')
.buttonMarkup({ iconpos: 'left', icon: 'arrow-l' });
}
});
});
The buttonMarkup plugin uses the A element's text and class values when creating itself but the other data- attributes result from the previous buttonMarkup and have to be removed, as does the inner html that the buttonMarkup creates (child span, etc). The title attribute was not recreated, for some reason, so I set it myself.
PS If anyone knows of a better way to achieve this (buttonMarkup('remove')? for example), please let us know.
the way i achieved it was changing a bit of the jquery mobile code so that the close button always came to the right, without an icon and with the text, "Close"
not the best way i agree. but works..
I got a similar case, and I did some dirty hack about this :P
$("#DanceStyles-button").click(function() {
setTimeout(function(){
$("#DanceStyles-dialog a[role=button]").removeClass("ui-icon-delete").addClass("ui-icon-check");
$("#DanceStyles-dialog .ui-title").html("<span style='float:left;margin-left:25px' id='done'>Done</span>Dance Styles");
$("#DanceStyles-dialog .ui-title #done").click(function() {
$("#DanceStyles").selectmenu("close")
});
},1);
} );

jQuery Mobile: Collapsible not expanded in pageinit, when coming back from other page

In my jquery-mobile (1.0RC2) application, I have two pages: test1.html, test2.html
The first page, test1.html, includes an collabsible-set, where I expand one collabsible item via script in the pageinit event listener (tried both pageshow and pageinit):
$('#page1').live( 'pageinit', initPage);
function initPage() {
alert('initPage!'); // this line seems to be always getting executed
$('#my_expandable').trigger('expand'); // ... but this line doesn't when coming back via a back link!
}
This works fine on the first call of the page.
Then I have a link that leads me to the second page test2.html, as follows:
<script>
function goPage2(criteria) {
$('#page1').die( 'pageinit', initPage);
$.mobile.changePage( "test2.html", {reverse: false, reloadPage: true} );
}
</script>
page 2
When I then go back to the first page via
<script>
function goPage1() {
$.mobile.changePage( "test1.html", { reverse: true, reloadPage: true} );
}
</script>
test
only the alert message in the pageinit event listener of test1.html is executed, but the collapsible is not being expanded through the
You can see the sample in action here: http://bit.ly/rr0dq3
How to reproduce the problem:
load test1.html at http://bit.ly/rr0dq3
you will get an alert message, and the collapsible will be expanded
click on the button 'GoTo page2' and you will come to the second page test2.html
on this second page, click on the gray button 'test', and you will come back to the first page test1.html
the problem now: as you can see, the alert command of the pageinit event of test1.html is being executed, but expanding the collapsible isn't - why not? Obviously the pageinit event listener method is being entered properly, but only the collapsible seems to have a problem here.
I think it might be a bug (filed a report here https://github.com/jquery/jquery-mobile/issues/2791), but maybe somebody else has an idea for that.
Workaround:
Both the alert and the collapsible expanding is being executed when I use a different way to to open the second page test2.html, using
window.location.href = "test2.html";
instead of
changePage(...);
But it's not very satisfying. Why does it not work properly if I use the the page injection way? I already call the die() method when I open the different pages in order not to have multiple pageinit event listeners keeping hanging around.
Have you tried using the data-attribute for collapsible content areas that makes them load expanded:
data-collapsed="false"
Here is a link to the docs for this behavior: http://jquerymobile.com/demos/1.0rc2/docs/content/content-collapsible.html

Jquery UI panel resizing on click

I am using Jquery Ui panels.([http://code.google.com/p/ist-ui-panel/][1])
While loading the application, everything is fine like collasible, draggable etc.
But i want to make the panel collapsible while clicking on some links.fo ex:
This code will run when the form is loading....
$('#myNews').panel({
'collapsible' :true,
'stackable':false,
});
The html
<div class="panel" id="myNews" >
<h3>Poll</h3>
<div>Some content</div>
</div>
I want to make 'collapsible' :false when clicking some link.... like this
$('#click1').click(function() {
$('#myNews').panel({
'collapseType':'slide-right',
'collapsible':false,
});
});
the code is running without any error, but the '#myNews' not getting affected when clicking the '#click1' link.
Need some help pls.
Thanks in advance
I'm the one behind ist-ui-panel, and Jesse was right — by now the only way for you is to use 'destroy' method somewhat like:
$(document).ready(function(){
$('#click1').bind({
'click': function() {
$('#myNews').panel('destroy');
$('#myNews').panel({
'collapsible' :true,
'collapseType':'slide-right',
'stackable':true
});
}
});
$('#click2').bind({
'click': function() {
$('#myNews').panel('destroy');
$('#myNews').panel({'collapsible': false});
}
});
});
Notice, you should explicitly destroy previous panel before making a new one.
If you read the uncompressed source code for that widget, it appears that what you are doing is only meant to be used to create panels, not to modify them afterward.
The underlying software is either buggy or I don't understand it. So you'll have to hunt down some bugs, but you can use the 'destroy' method on that widget to reset the div completely, and then make it a panel again, like so:
$('#myNews').panel("destroy");
$('#myNews').panel(...
As I said, it's buggy or I don't quite get it - there's an error raised by the destroy call which you have to catch, and subsequent calls to make new panels do make panels, but they aren't completely correct.
