jQuery Mobile default tab - jquery-mobile

I want to set a default tab in jQuery Mobile.
My source code:
<div data-role="tabs" id="tabs">
<div data-role="navbar">
<ul>
<li>one</li>
<li>two</li>
<li>three</li>
</ul>
</div>
<div id="one" class="ui-body-d ui-content">
<h1>First tab contents</h1>
</div>
<div id="two">
<ul data-role="listview" data-inset="true">
<li>Acura</li>
<li>Audi</li>
<li>BMW</li>
<li>Cadillac</li>
<li>Ferrari</li>
</ul>
</div>
</div>
$("#tabs").tabs({ active: 0 });
It worked but has no background color, because the first tab is not actually clicked.
I want to set default tab with background when I login in.
No background color demo

To set the active tab, try:
$( "#tabs" ).tabs("option", "active", 1);
Here is a working DEMO
UPDATE: the blue background on the tab button comes from the class ui-btn-active. Either add this class to the button, or instead of setting the active tab, trigger the click event on the appropriate button: http://jsfiddle.net/ezanker/c29gd4h6/1/

I have added class="ui-btn-active" in first tab-li
<div data-role="navbar">
<ul>
<li>One</li>
<li>Two</li>
</ul>
</div><!-- /navbar -->
If not work then try below It working for me when page load only I mean refresh page in browser
Put following code in jquerymobile pagecreate event that will make every first tab selected
$('[data-role="tabs"] a:first').each(function() {
$(this).click();
});
I had put above lines into pagecreate event
$(document).on("pagecreate", "#homepage", function(event) {
$('[data-role="tabs"] a:first').each(function() {
$(this).click();
});
});
In above line #homepage is my page id and pagecreate is event of jquery-mobile that fire when page load/init

HTML
<div data-role="tabs" id="tabs">
<div data-role="navbar">
<ul>
<li>Default</li>
JS
$(document).on("pagecreate", function (event) {
$('#tab-one').trigger('click');
});

I found the existing mentioned solutions had issues:
the one by #ezanker showed the content but didn't set the tab button as active
the one by #Devendra Chhaiya clicked any first link that the tab content contained also! :-)
I also found that the tab wasn't remaining selected when coming back to that page, so I used this solution to fix that too.
there was also an issue with pages loading into tab content, so I had to fix that too
in addition (yes, there's more :-) I wanted to selected a specific tab based on the requirements of that specific page, so I added a class select-this-tab on page generation from the server.
So I modified the one by #Devendra Chhaiya to click only the actual tab button (and not any tab content, keep the tab selected, and also prevent content loading into the tab area. I had to move the trigger from pagecreate to pageinit for it to work:
/*
* https://stackoverflow.com/questions/13837304/jquery-ui-non-ajax-tab-loading-whole-website-into-itself/17384908#17384908
*/
jQuery(function () {
jQuery('base').remove();
jQuery("#tabs").tabs();
});
$(document).on('pageinit', function () {
console.log('pageinit');
/*
* Ensure the correct tab of a set is selected (and only once)
* https://stackoverflow.com/questions/25336233/jquery-mobile-default-tab/64080164#64080164
*/
$('[data-role="tabs"] [data-role="navbar"] ul li.select-this-tab').each(function () {
console.log('Clicking tab');
$(this).removeClass("select-this-tab").find("a").click();
});
/*
* Ensure a tab REMAINS selected when coming back to that page.
* https://stackoverflow.com/questions/16752704/tab-active-state-in-jquery-mobile/23725612#23725612
*/
$('div[data-role="tabs"] [data-role="navbar"] a').click(function (e) {
e.preventDefault();
$('div[data-role="tabs"] [data-role="navbar"] .ui-btn-active').removeClass('ui-btn-active ui-state-persist');
$(this).addClass('ui-btn-active ui-state-persist');
});
You can remove the console.log lines which you can just use to prove the code actually fires.

Two similarly syntaxed menus - the one in footer works; the one in the header does not

I am learning to make menus. In a tutorial I learned to make a mobile-friendly menu (http://designshack.net/articles/css/responsive-slide-down-navigation). The page I created is at http://nspowers.org/ask/why-menu and uses lists for the links.
The links in the footer work. However, links with identical syntax in the top menu do not link.
Here is the structure of the working footer navigation:
<footer id="hfooter">
<div class="footer_nav">
<nav>
<ul>
<li> Home </li>
<li> Work </li>
<li> About </li>
<li> Contact </li>
</ul>
</nav>
</div>
<div class="copyright">&copy</div>
</footer>
This is the structure of the top navigation that is not working:
<header id="topnav">
<nav>
<ul>
<li> WORK </li>
<li> ABOUT </li>
<li> CONTACT </li>
</ul>
</nav>
Nav Menu
<h1>This is the 'home' page</h1>
</header><!-- #end #topnav -->
The css is here: http://nspowers.org/ask/why-menu/styles.css.
I would like to learn what other variables may affect successful linking other than the syntax of the links I've looked at in tutorials.
Solved it.
1) First, the menu.js from file has the following in the third section:
$('#topnav nav a,#topnav h1 a,#btmnav nav a').on('click', function(e){
e.preventDefault(); // stop all hash(#) anchor links from loading
});
Thank you to http://disqus.com/ashearlam, this doesn't need to be there. Delete it. It was supposed to stop the menu from linking away within a mobile view. However, it works fine without it. The working menu.js is as follows:
$(function(){
var nb = $('#navbtn');
var n = $('#topnav nav');
$(window).on('resize', function(){
if($(this).width() < 570 && n.hasClass('keep-nav-closed')) {
// if the nav menu and nav button are both visible,
// then the responsive nav transitioned from open to non-responsive, then back again.
// re-hide the nav menu and remove the hidden class
$('#topnav nav').hide().removeAttr('class');
}
if(nb.is(':hidden') && n.is(':hidden') && $(window).width() > 569) {
// if the navigation menu and nav button are both hidden,
// then the responsive nav is closed and the window resized larger than 560px.
// just display the nav menu which will auto-hide at <560px width.
$('#topnav nav').show().addClass('keep-nav-closed');
}
});
$('#navbtn').on('click', function(e){
e.preventDefault();
$("#topnav nav").slideToggle(350);
});
});
2) The webpage was missing a mobile meta viewport, so the website was not being scaled down to a mobile view when viewed on a mobile device. Adding the meta,
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1">
resolves this issue.

jQuery Mobile: how to make buttons that don't reload the page (href)?

According to the jQuery 1.1.0 Mobile documentation a button should be defined as a link.
Link button
This loads the referenced page.
When using the # it reloads the current page.
Action
How could we define a button that is not a link and simply triggers an event handler when an event on it occurs ?
Edit: my interpretation of what I saw was wrong. Clicking on a button with href="#" doesn't reload the page. I should delete the question because it doesn't make sense.
To my understanding the href="#" does not refresh the page, Example:
http://jsfiddle.net/XNLWS/
Here are the jQM Docs:
http://jquerymobile.com/demos/1.1.0/docs/buttons/buttons-types.html
If you're looking for a custom event, here is an example:
http://jsfiddle.net/XNLWS/1/
JS:
$( "#myButton" ).bind( "click", function(event, ui) {
alert('Custom action here');
});​
HTML:
<div data-role="page" id="home">
<div data-role="content">
Link button
</div>
</div>​

Sharing an element between jQuery UI tabs?

I'm using jQuery UI's tabs to divide content on my page. I have a 'link bar' I would like to have hang at the bottom of each tab. (The tab text will change but generally they will navigate the user left or right through tabs.)
Hosting the #linkBar div inside the first tab makes it 'look' right, inside Themeroller's border. Putting it just outside the 'parent tab' div places the links below the theme's border. I've tried creating a spacer div but it just pushes #linkBar down further.
Of course when the user switches to another tab, the link bar goes away. How is ownership of elements organized between tabs? Should I dynamically destroy the #linkBar div on the tab being navigated away from and rebuild it in the tab being navigated to? Or is there a better way to move it between them, or just manage visibility?
I would like to have the link bar follow the content on each tab as a footer, 'floating' one or two lines below the last content of each tab (rather than having it in a fixed position relative to the tab bar).
Ok ... It was simply adding the jQuery UI classes to the linkBar. Check out my working jsFiddle demo:
I moved the linkBar div out of the tabOne div and put it at the bottom of the tabs div:
<div id="container">
<div id="title">
<h1>title bar</h1>
</div>
<div id="tabs">
<ul>
<li>one</li>
<li>two</li>
<li>three</li>
</ul>
<div id="tabone">
content goes here
<br><br><br><br>more stuff<br><br><br>more stuff<br><br>
</div>
<div id="tabtwo">
content goes here...
</div>
<div id="tabthree">
content goes here...
</div>
<div id="linkBar">
<span id="leftLink"><< left link</span>
<span id="rightLink">right link >></span>
</div>
</div>
</div>
I slightly altered the linkBar style by giving it a top and bottom margin as well as hiding it by default:
#linkBar {
display: none;
margin: 10px auto;
}
Then I simply added the jQuery UI classes to the $linkBar. I slightly altered the jQuery to be more readable:
$("#accordion").accordion({ header: "h3" });
var $tabs = $("#tabs"),
$linkBar = $("#linkBar");
$linkBar.addClass("ui-tabs-panel ui-widget-content ui-corner-bottom");
$linkBar.show();
$tabs.tabs();
$('#title').click(function() {
$tabs.tabs('select', 0);
return false;
});
Note: You could just add class="ui-tabs-panel ui-widget-content ui-corner-bottom" to the linkBar div and be done with it. But, I think I like it better managed in the JS.

jQuery UI Accordion Scrolling issue

I have a page with several sections of significantly varying length within a jQuery UI Accordion. If I open a new section (which collapses one of the longer sections above), I'm left at the bottom of the page. Because the sections are of significantly different heights, I can't use the autoheight feature without it looking very strange. Is there any way to use something like scrollto to automatically go to the top of the section I've just expanded?
You can bind a function to the accordionchange event and use jQuery scrollTop():
JavaScript
$(function () {
$("#accordion").accordion({
autoHeight: false,
header: "h3"
});
$('#accordion').bind('accordionchange', function (event, ui) {
$(window).scrollTop(ui.newHeader.offset().top);
});
});
HTML
<div id="accordion">
<div id="accordion-one">
<h3>First</h3>
<div>Some lengthy text</div>
</div>
<div id="accordion-two">
<h3>Second</h3>
<div>Less lengthy text</div>
</div>
<div id="accordion-three">
<h3>Third</h3>
<div>Other text</div>
</div>
</div>
I tested this in FF8.

jQuery scrollTop()

Can I stop the page from 'scrolling' back to the top when a user clicks on a tab (with Rails not Javascript)?

Ive built a webpage with 'tabs' using rails. When a user clicks a tab, a new page loads. I want to format it so the tabs are always in the same place on the page as a user clicks them. This happens as long as the user has not scrolled down on the page. If a user has scrolled down, clicking on the tab will refresh the page and it is no longer scrolled down - which make clicking the tabs look bad. Is there a way to keep the spot on the page where the user has scrolled down, without using Javascript? If it must be done with Javascript, any suggestions?

Without Javascript, nope. If they were at an exact location, you would be good to go, using an anchor (example.html#anchor), but since you don't know the exact location, you're pretty much out of luck.
So sorry!
You can do it but you will need a small amount of Javascript and some CSS hiding.
Suppose these are your tabs:
<ul id="nav">
<li class="tab">Content 1</li>
<li class="tab">Content 2</li>
</ul>
And suppose this is your content:
<div id="content" class="content1">
<div id="content1">
<h1>Some content</h1>
<p>This is my content.</p>
</div>
<div id="content2">
<h1>More content</h1>
<p>This is my other content.</p>
</div>
</div>
What you would need to do then, and I am demonstrating using the Ext.Core library, is:
<script type="text/javascript">
Ext.onReady(function() {
Ext.select('.tab a').on('click', function(ev, el) {
ev.stopEvent();
var content_id = el.href.replace('#', '');
Ext.get('content').removeClass(['content1', 'content2', ...]).addClass(content_id);
});
});
</script>
You also need a little CSS like so:
#content.content2 #content1,
#content.content1 #content2 {
display:none;
}
This hides the other content we are not looking at. We set a class on the content container called contentN which is the href of the link for that tab. So if we have a tab with href="#content1" then we add a class to the content container called content1 and now that content is visible and other content is not.
The Ext.Core samples page has another way of doing it, and they have an example up showing it working. Their way is more involved than this.
