I am using nanoscroller to show a list of items.
However, in some cases, I load the content via ajax and modify the div.content of the nano.
The problem is that the content is not renedered, although it is there.
<div class="nano">
<div class="content>
<li> asddas </li> <!-- this is loaded via ajax -->
</div>
</div>
Try to fire this on ajax success.
$(".nano").nanoScroller();
This will refresh the scrollbar.
Here are some good references that can help you with this.

I am trying to implement ajax loading for the joomla 3.2.1 default contact form component.
I set a menu link to the contact form in the backend.
This is the HTML output :
<nav id="menu2">
<div class="moduletable">
<ul class="nav menu">
<li class="item-138">Contact
</li>
</ul>
</div>
</nav>
and I have this div at the bottom of the page :
<section id="contact_form">
</section>
I implemented this Jquery code :
$('.item-138 a').click(function () {
$('#contact_form').load("index.php?option=com_contact&view=contact&id=1&tmpl=component")
return false;
});
The contact form loads well and my template override works. but how can I prevent loading the <head> content that comes with it?
The <title> tag, default scripts (mootools jquery...) and default css ( /templates/system/css/general.css, /templates/system/css/template.css)
Can I do that with a template override? Is it even possibler?
Well there is this value that you attach to the get request.
&format=raw
so your request looks like
index.php?option=com_contact&view=contact&id=1&tmpl=component&format=raw
also you may want to make a copy of your view.html.php and rename it view.raw.php
You should be able to load part of the page you want from the load, something like this.
$('#contact_form').load('index.php?option=com_contact&view=contact&id=1&tmpl=component #formID');

Am creating a web application having 4 tabs... Each tab contains a sidemenu (jQuery) and the remaining part is divided into 2, topdiv and bottom div (table with 2 colums.. col1=sidemenu, col2=topdiv+bottomdiv) ... I use
$("#topdiv").load("contents/abc.html #xyz")
To load contents of div xyz to topdiv, which(xyz) is in another page abc.html when I click a particular link in the sidemenu... But sometimes when #xyz will again have 4 or 5 tabs ,those tabs are not available as tabs in #topdiv... instead they appear as just list.. am using $("#___").tabs() for creating tabs...can anyone help me? I cannot add images here since am not having enough reputations in stack overflow. if some one provides ur email address I can attach images of my current status of page and those of which I need to design... here is part of ma code.

pls note that div '#mainmenu' is appearing in tab format... but "#innertabs" also having class "tabs" is not appearing in tab format.. instead they appear in #topdiv as lists and contents below it
===========================================================================================
I assume you using jquery ui tabs.
If so after loading other page content, apply again tabs function on main div
$( "#tabs" ).tabs();
Actually you should apply .tabs() after ajax content is loaded. Not before that. I am not sure if applying .tabs() twice may damage it.
Update:
Here is fiddle for you Example . then your code will be
$("#mainmenu").tabs();
$("#topdiv").load("contents/abc.html #xyz");
$("#innertabs").tabs();
atlast after a lot of researchs and experiments, i hav found a solution to this... actually i hav to use unique div ids for tabs instead of class = "tabs"... then the tab statement will change to $("#innertabs").tabs(); but to make sure that $().tabs() is invoked only after loading the contents, put that statement in a callback function of $().load()... so my actual problem was $("#innertabs").tabs() is invoked even before it is loaded into #topdiv from the page abc.html..hence they can be displayed only as lists as there is no div with id=innertabs at the time of $().tabs() is invoked. . now it is avoided and the working code is
$("topdiv").load("contents/abc.html #xyz",function(){$("#innertabs").tabs();});
so only after loading the div into topdiv, corresponding tabs are generated and thus it will be displayed as tabs itself
so i think its good to use a callback function all the time when u need this stuff to be done without any errors...
also if anyone came to know about the disadvantages of this method pls do post here.. it wll be helpfull for me as a fresher
looking forward to a career in software development...
I am trying to add a Tripadvisor widget (rave) to my page which is loaded via Ajax.
Here is the widget code:
<div id="TA_cdsscrollingravewide869" class="TA_cdsscrollingravewide">
<ul id="1NcDZBZ" class="TA_links 8dTZRew">
<li id="ZweVlS" class="3cqMCWiB">Read 37 reviews of <a target="_blank" href="http://www.tripadvisor.com/Restaurant_Review-g188590-d946177-Reviews-Bond-Amsterdam_North_Holland_Province.html" onclick="ta.cds.handleTALink($cdsConfig.getMcid()); return true;">Bond</a></li>
</ul>
</div>
<script src="http://www.jscache.com/wejs?wtype=cdsscrollingravewide&uniq=869&locationId=946177&lang=en_US&border=true&shadow=true&backgroundColor=white"></script>
Only when the page loads the first time it's get rendered. But after an ajax load it doesn't.
I tried to use jQuery's getScript function but it doesn't help. Even manually deleting the added script en link nodes from the head before executing the script again doesn't help.
Can anyone help me fixing this please?
The solution:
$.getScript('//www.tripadvisor.fr/WidgetEmbed-selfserveprop?nreviews=6&uniq=&iswide=true&locationId=' + tid + '&rating=true&popIdx=true&border=false&writereviewlink=true&lang=fr', function() {
if (typeof(window.taValidate) != 'undefined') {
window.taValidate();
}
});
Perhaps the html iframe is a method.
ex.
<iframe src="tripadvisor.php" scrolling="no" frameborder="0"></iframe>
tripadvisor.php
<div id="TA_cdsscrollingravewide869" class="TA_cdsscrollingravewide">
<ul id="1NcDZBZ" class="TA_links 8dTZRew">
<li id="ZweVlS" class="3cqMCWiB">Read 37 reviews of <a target="_blank" href="http://www.tripadvisor.com/Restaurant_Review-g188590-d946177-Reviews-Bond-Amsterdam_North_Holland_Province.html" onclick="ta.cds.handleTALink($cdsConfig.getMcid()); return true;">Bond</a></li>
</ul>
</div>
<script src="http://www.jscache.com/wejs?wtype=cdsscrollingravewide&uniq=869&locationId=946177&lang=en_US&border=true&shadow=true&backgroundColor=white"></script>
A far from optimal solution which I had to adopt in a similar scenario was based on the following logic:
Invoke the tripavisor script just once and load the widget inside an hidden html element on whathever page the user lands (so the page is not rendered by an ajax request).
When the page where you want the widget placed is called by ajax, if the request is successfully completed, check if the widget is already in DOM, clone it and inject or append it to the ajax generated piece of html.
I found another solution. If you have the widget HTML on the page, or if you added it via jQuery to the page, e.g. this one:
<div id="TA_cdsscrollingravewide869" class="TA_cdsscrollingravewide">
<ul id="1NcDZBZ" class="TA_links 8dTZRew">
<li id="ZweVlS" class="3cqMCWiB">Read 37 reviews of <a target="_blank" href="http://www.tripadvisor.com/Restaurant_Review-g188590-d946177-Reviews-Bond-Amsterdam_North_Holland_Province.html" onclick="ta.cds.handleTALink($cdsConfig.getMcid()); return true;">Bond</a></li>
</ul>
</div>
you can execute this script below, and it will load the widget:
$.getScript("https://www.tripadvisor.com/WidgetEmbed-cdsscrollingravewide", function(){
if (typeof(window.taValidate) != 'undefined') {
window.taValidate();
}
});
Please note that for example in my case the widget class is TA_cdsratingsonlynarrow, so
for me the script URL looks like this:
https://www.tripadvisor.com/WidgetEmbed-cdsratingsonlynarrow
I'm using Jquery mobile for my mobile application. before I changing a page I want to make some CSS changes on that page. When I am setting for example adding class to id of the next page,or color change: $("#divA1").css("background-color","blue");
It change the same id on the current page (if it exist) and only then change next page. How can I set my CSS settings while on one page but load the next page with those CSS settings.
In most scenarios, jQuery Mobile loads additional pages into the DOM via ajax calls. This is a fairly fundamental part of how it works and you should insure that all markup IDs across all pages are unique.
<div id="page1" data-role="page">
<div data-role="content">
<div id="myContent1"></div>
</div>
</div>
<div id="page2" data-role="page">
<div data-role="content">
<div id="myContent2"></div>
</div>
</div>
If your pages contain similar sub-componants, consider a class instead:
<div id="page1" data-role="page">
<div data-role="content">
<div class="myContent"></div>
</div>
</div>
<div id="page2" data-role="page">
<div data-role="content">
<div class="myContent"></div>
</div>
</div>
Classes allow for selection such as $("#page1.myContent").css("background-color");
If it must be on a new page, you have three options.
You can pass a variable in the URL to test on the new page and change the CSS appropriately. eg. www.url.com?newcolor=f00
You can put a hidden form on the current page, update the values in it and pass it when you go to the next page. (Ugly way to do it but it works.)
Set a cookie. (My preferred solution, works great as long as cookies are enabled. Which, honestly, they may not be.)
However, the best option, especially on a mobile device is to keep the current framework of the page and get new content via ajax and load it into a content div on the current page.
I don't understand exactly what you're trying to do, but I would suggest you using an asynchronous ajax call to download the DOM of the next page.
Then you can apply the changes you want to that DOM, and finally you plug it into your current DOM.
An stub for that woul look like this:
$.ajax('path/to/next/page', {
async : true,
complete : function ajaxCallback(newSite) {
$item = $('YOURSELECTOR');
// Here you can make changes, such as CSS edition
$item.css({'background-color' : '#FF0000'});
// Since you want to make changes to the new site only if you did them in the first site...
if ($item.length > 0) {
$(newSite).find('YOURSELECTOR').css({'background-color' : '#FF0000'});
}
// Here you can append the new site to the DOM
}
});
I have a page with an iframe to feature the contents of the clicked tab. There are 3 tabs and 1 iframe. The sources of the contents relating to each tab clicked are formatted and coded in other html & css files.
What is another alternative to using an iframe, because I noticed that when the tab is clicked, it still shows the white background, similar to when a new page is loading?
Here's my code:
<div id="tabs">
<div id="overview">
<a target="tabsa" class="imagelink lookA" href="toframe.html">Overviews</a>
</div>
<div id="gallery">
<a target="tabsa" class="imagelink lookA" href="tawagpinoygallery.html">Gallery</a>
</div>
<div id="reviews">
<a target="tabsa" class="imagelink lookA" href="trframe.html">Reviews</a>
</div>
</div>
<div id="tabs-1">
<iframe src="toframe.html" name= "tabsa" width="95%" height="100%" frameborder="0">
</iframe>
</div>
The only alternative to using IFRAMEs to load dynamic content (after the page has loaded) is using AJAX to update a container on your web page. It's pretty elegant and usually faster than loading a full page structure into an IFRAME.
Ajax with JQuery (use this and you will be loved on SO; the AJAX functions are great and simple)
Ajax with Prototype
Ajax with MooTools
Standalone Ajax with Matt Kruse's AJAX toolbox (Used to use this, using JQuery today because I needed a framework)
AJAX with Dojo (Said to be fast, but AJAX is not as straightforward)
Another alternative is to use AJAX to load the content of a tab and use a div to display the content. I would suggest that using an existing Tab library might be an option rather than trying to solve all the problems associated with creating tabs.
Maybe the jQuery UI Tab might be helpful here if you like to try it.
EDIT: AJAX example with UI Tabs.
First, the HTML will look like this.
<div id="tabs">
<ul>
<li><span>Overviews</span></li>
<li><span>Gallery</span></li>
<li><span>Reviews</span></li>
</ul>
</div>
Then make sure that you import the appropriate jQuery files:
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/ui-lightness/jquery-ui.css" type="text/css" media="all" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" type="text/javascript"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.min.js" type="text/javascript"></script>
etc...
Then add the code to create the tabs:
<script type="text/javascript">
$(function() {
$("#tabs").tabs();
});
</script>
There's an alternative to AJAX!
You can load ALL three possible contents into separate DIVs.
Then clicking on a tab will simply make the display attribute of the appropriate content's DIV "block" while making the other two DIVs' display property "none".
Cheap, easy, does not require AJAX costs for extra http request or for coding.
Mind you, AJAX is a better solution if the contents of the tabs will change dynamically based on other data as opposed to being known at the time the page loads.
You don't need script.
<ul><li>foo link<li>bar link</ul>
<div class="tab" id="foo">foo contents</div>
<div class="tab" id="bar">bar contents</div>
Plus this CSS, in most browsers: .tab:not(:target) { display: none !important; }, which defaults to all content visible if :target isn't supported (any modern browser supports it).
If you're showing content with script, always hide it with script. Let it degrade gracefully if that script doesn't run.
It's probably better to load in the content for each tab into DIVs on the same page and then switch the visibility of each DIV when a tab button is clicked using JavaScript and the CSS display property.
If you can't do that then iframe is probably the best solution. You can make the iframe background transparent, see below:
<iframe src="toframe.html" name= "tabsa" width="95%" height="100%" frameborder="0" allowtransparency="true"></iframe>
You would then need to add the following CSS to the BODY element using:
BODY { Background: transparent; }
The HTML iframe is to be used to include/display non-template content, such as a PDF file. It's considered bad practice when used for template content (i.e. HTML), in both the SEO and UX opinions.
In your case you just want to have a tabbed panel. This can be solved in several ways:
Have a bunch of links as tabs and a bunch of div's as tab contents. Initially only show the first tab content and hide all others using CSS display: none;. Use JavaScript to toggle between tabs by setting CSS display: block; (show) and display: none; (hide) on the tab content divs accordingly.
Have a bunch of links as tabs and one div as tab contents. Use Ajax to get the tab content asynchronously and use JavaScript to replace the current tab contents with the new content.
Have a bunch of links as tabs and one div as tab contents. Let each link send a different GET request parameter or pathinfo representing the clicked tab. Use server-side flow-control (PHP's if(), or JSP's <c:if>, etc) or include capabilities (PHP's include(), or JSP's <jsp:include>, etc) to include the desired tab content depending on the parameter/pathinfo.
When going for the JavaScript based approach, I can warmly recommend to adopt jQuery for this.
This is jQuery example that includes another html page into your document. This is much more SEO friendly than iframe. In order to be sure that the bots are not indexing the included page just add it to disallow in robots.txt
<html>
<header>
<script src="/js/jquery.js" type="text/javascript">
</header>
<body>
<div id='include-from-outside'></div>
<script type='text/javascript'>
$('#include-from-outside').load('http://example.com/included.html');
</script>
</body>
</html>
You could also include jQuery directly from Google: http://code.google.com/apis/ajaxlibs/documentation/ - this means optional auto-inclusion of newer versions and some significant speed increase. Also, means that you have to trust them for delivering you just the jQuery ;)
As mentioned, you could use jQuery or another library to retrieve the contents of the HTML file and populate it into the div. Then you could even do a fancy fade to make it look all pretty.
http://docs.jquery.com/Ajax/jQuery.get
Something along these lines:
$.get("toframe.html", function(data){
$("#tabs-1").html(data);
});
edit..
you could prepopulate or onclick you could do the get dynamically
$("#tabs a").click(function(){
var pagetoget = $(this).attr("href");
$.get...
})
If you prepopulate could have three containers instead of the one you have now, 2 hidden, 1 display, and the click functions will hide them all except for the one you want.
The get is less code though, easier time.
