I'm using jquerymobile. And on a list I have a filter. When a user types something in it filters great. However when I add more items to the list, then the filtering does not refresh.
Any idea how I can refresh the filtering? (re-filter the list?)
Thanks
Trigger a change event on the search input field like this after items are added to list.
$(".ui-input-search .ui-input-text").trigger("change");
A sample:
<html>
<head>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" />
<script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
<script>
$("#btn").live("click",function(){
$("#list").append("<li><a href='#'>100</a></li><li><a href='#'>200</a></li><li><a href='#'>400</a></li><li><a href='#'>500</a></li><li><a href='#'>1000</a></li>");
$("#list").listview("refresh");
$("#page").trigger("create");
$(".ui-input-search .ui-input-text").trigger("change");
});
</script>
<script src="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js"></script>
</head>
<body>
<div id="page" data-role="page">
<div data-role="header">
<h1>Test Page</h1>
</div>
<div data-role="content">
<ul id="list" data-role="listview" data-inset="true" data-filter="true">
<li>1</li>
<li>12</li>
<li>41</li>
<li>8</li>
<li>91</li>
<li>65</li>
</ul>
<a data-role="button" id="btn">Add more</a>
</div>
</div><!-- /page -->
</body>
</html>

Let me know if that helps.
Update for jQuery Mobile 1.4
The filter behavior has been separated out into a filterable widget. You can update your listview content and rerun the filter in one swipe:
$( ".listselector" ).filterable( "refresh" );
A nice benefit of this is that the list items are filtered immediately. You do not experience the visual glitch of seeing the items for a split second before they get filtered, as you would when manually triggering the input control.
See http://api.jquerymobile.com/filterable/#method-refresh
The code above would no longer work, because jQuery Mobile keeps track of the last text entered into the filter, and does not filter if the input has not changed. If you did want to trigger the input control, you would need the following hack to first clear the last entered input:
$(".ui-input-search input").attr('data-lastval', '').trigger("change");
But, please use the filterable function going forward.
I think the problem should be resolved with refresh method, but I am not sure:
$('#mylist').listview('refresh');
After updating the list view, adding the below code will refresh the contents so that it becomes visible :
$("#list").listview("refresh");
Besides using the previously mentioned listview refresh, take note that using jQuery's .show() on a listitem will cause display:block; to be added to the element's CSS. Because it takes precedence over jQM's ui-screen-hidden class, it interferes with the searchfilter's ability to hide items when they don't match.
So if you are adding items to the list by way of .show()/.hide() combos, use .css('display','') instead of .show().
My general order for adding new hidden items:
// 1. Clear display:none and display:block, if necessary, from the listitem
$(yourLI).css('display','');
// 2. Apply jQM formatting, such as corners and other CSS, to the entire listview
$(yourListView).listview('refresh');
// 3. Make sure the searchfilter runs on the new items without user intervention
$(".ui-input-search .ui-input-text").trigger("change");

I am very new to jQuery and not entirely sure what I'm doing. Will try my best to explain the problem I'm facing.
I'm trying to lock some content on a landing page until a user shares the link using FB, Twitter, LinkedIN or G+. The first version of the script I wrote (which worked fine) ran like this:
<head>
<script type="text/javascript">
...
$(document).ready(function()
{
$('.class').click(clearroadblock());
buildroadblock();
}
</script>
<style>
.class
{
[css stuff]
}
</style>
</head>
<body>
<div id="something">
<ul>
<li> Link1 </li>
<li> Link2 </li>
</ul>
</div>
</body>
The problem I'm now facing is changing out this code to replace the list elements with social share buttons. As they are no longer under .class, but classes like fb-share-button and twitter-share-button. Please help me understand what I need to modify to accommodate this? PS: This is not a Wordpress site.
function clearroadblock()
{
$('#roadblockdiv').css('display', 'none');
$('#roadblockBkg').css('display','none');
}
This is the way I'm clearing the overlay once a click is detected, BTW.
Can I wrap the social buttons in divs, assign them IDs and use those IDs to trigger the click like below?
<div id="Button">
Tweet
</div>
$('#Button').click(clearroadblock());
You can have multiple classes on an element by separating them with a space. Try the following:
class="class fb-share-button"
Your jquery will still work off the "class" class. I would recommend you change this name to something more meaningful though. Your css can target the "class" for general styles, but you can also target fb and twitter separately.
Update
I decided to create a quick JSFiddle for this.
Some of the styles etc won't be the same as what you're doing, but the problem is resolved. I've created a div with id main that contains the content that you want to hide. There's an absolutely positioned div over the top of this, this is the roadblock. The javascript is showing the roadblock (assuming that's what you wanted to do with buildroadblock()).
On click of a link in the ul with id socialMedia we call clearroadblock. Notice the lack of parenthesis. This hides the roadblock.
This isn't a great way of preventing someone from seeing information, you might want to think about pulling the content down from the server when the action is performed, however, I think this answers your question.
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.

$(".tabs").tabs();
$("#topdiv").load("contents/abc.html #xyz");
enter code here
========================================================================================
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...
Only this much now: I'm creating a vcard design for myself. My motivation is to make it look as good as possible. I want to apply to a webdesign company with this vcard to get a professional education for webdesign.
I still have a lot to change till it completely fulfills in my requirements, but this is my current version of the design I just uploaded to get you an overview over the design.
So as you can see it's focused on retro, vintage, ribbons and scetch elements.
Right know I want to get rid of these jerking content refreshs. So I thought a dynamic content swap via ajax and jQuery would be the best way to do it.
I never did much with js or actually ajax.
I want to ask you guys about a solution you think benefits in my design. I was thinking about something smoothly.
The content which needs to be changed is placed in
<nav>
(...)
<ul class="ribbon s"><!--Following links got the class="ribbon b/p/l/k"-->
<li class="ribbon-content">Link</li>
<!--
?content=blog
?content=portfolio
?content=lebenslauf
?content=kontakt
-->
</ul>
(...)
</nav>
<section id="content">
<div class="con clearfix">
(...)
</div><!--An empty div for possibly swapping without touching the vintage paper thing -->
</section>
http://robert-richter.com/boilerplate/
for example use jquery.
first add jquery to your html. within the domready-event you can register click events on your ribbon-menue. on each click you load the div-content from the given link-url in the html-part.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
$.ready(function(){
$(".ribbon-content a").on("click", function(event){
event.preventDefault();
$(".con").load($(event.target).attr("href"), function(){
// add code after loading - for example change classes of menue
})
});
})
</script>
additionly you can the the browser-history to enable the prev- and next-buttons of the browser.
I've been having nothing but problems with this script for a simple hide/show gallery of testimonials.
I think the java is somewhat self explanatory...
When the page loads, I tell it to show the first testimonial in the line up (as the css is display:none) and gives it a selected class name. Works fine in across the board.
On click I want it to remove the selected class place it to another, and then hide the first testimonial and pull up a corresponding one. Except all that happens here is the first testimonial disappears (hide) and the selected class is added.
<script type="text/javascript">
$(document).ready(function(){
$(".testimonial:first").show();
$("li.testID:first").addClass("selectedName");
$("li.testID").click(function(){
$("li.testID").removeClass("selectedName");
$(this).addClass("selectedName");
$(".testimonial").hide();
$(this).next(".testimonial").fadeIn("slow");
});
});
</script>
Example of markup
<ul id="testName">
<li class="testID">Persons Name</li>
<blockquote class="testimonial">
<span class="bqStart">“</span>
Testimoinal here
<span class="bqEnd">”</span><br /><br />
<span class="testAuthor"><b>Name</b><a target="_blank" href="#">Website</a> Company</span>
</blockquote>
As a side note this is working fine in FF and Safari
Your help is greatly appreciated.
Thanks.
It's probably not working in IE because it's not valid markup: you can't have a blockquote as a direct child of a UL, so IE probably stores them in some weird place in the DOM tree which means .next doesn't find them. Can you move the blockquote elements into the li?
Is .testimonial the class you have given to your lists? <ul> or <ol>
It seems as if you are trying to get the next testimonial list to show, when infact you are actually getting the next <li> which has a class of .testimonial which I suspect is incorrect as you are using .testID as the class for your list items.
Please try this instead:
$(this).parent().next(".testimonial").fadeIn("slow");
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.
