A simple
$('#slider .navigation li').length;
will make it. ;)

[jQuery] Re: click(function() works only once per page load?
Your click handler only applies to the elements matching
".ajax_homes_primary_img" at the time the click() function is called.
When you replace it, the new element has no event listeners attached.
You can either rebind the event every time you modify it, or use the
'live' function, which uses event delegation: http://docs.jquery.com/Events/live
That's as simple as changing $(".ajax_homes_primary_img").click
(function(){ to $(".ajax_homes_primary_img").live('click', function()
{...

[jQuery] number of elements with a specific CSS class
Hello guys,
is there a way to know how many element have a specific CSS class?
I have a list and I need to know how many items it contains.
I guess it should be omething like: $('#slider .navigation li'). ...
Thanks
[jQuery] Re: Why isn't there any list widget?
Sorry, that site is a bad example. I was referring to the list of links on the site. I can't just use CSS because I want the list to be dynamically generated with addItem() and removeItem() methods, and I also want items to be selectable.

[jQuery] Re: retrieving DOM element with specific CSS class
The jQuery('some_selector') method will retrieve an array of objects, no
matter how many items exists with that selector.
In your case you should use something like this:
jQuery('#slider.navigation a.selected')[0].id;
^^ (you
missed the array position of the element)

[jQuery] Re: Call for contributors: A simple, fast and flexible grid/spreadsheet component.
Well, so far my lesson from that project has been 'do the other things first until you find the right grid'. It's a really big project, so I've had plenty keeping me busy in the mean time. What I do know is that making a grid out of a normal table severely limited my ability to do creative things with it - not all things that have data that falls into a grid, should sort like a grid, etc, looks like a perfect table. One implementation that would be exceptionally useful to me that I see your grid fitting into would be a dataset that gets loaded in the background so that pagination to the next 'page' of results in the grid get cached in javascript... in the background. if the 'next page' worth of data has been loaded, the grid immediately uses the data upon a next event. If it has not, then it waits for an ajax request for the info to be returned. The next hurdle would be sorting those columns, as it would only be able to sort using just what it has retrieved if it retrieved the entire set, otherwise it would have to do an ajax call to allow the server-side to return the dataset pre-sorted (using sql). Any thoughts on any of that? The main point of the above example is that your grid, seeing as its dataset is in javascript (arrays) and not in the DOM, I feel this would be easier for me to implement, and the implementation could make faster decisions about what to do next based on it's current cache of data vs what the server said was left. Am I barking up the right tree here? I see what you mean about the need for docs and solid ground - hopefully this discussion will arouse interest. The fact that you are not just creating a giant table in the DOM, and instead showing only what is necessary should be enough to peek an adept ajaxer's interest. I'd be all over helping you build this, however I'm not so much a javascript ninja yet. I'll be playing with it here, and will certainly offer my thoughts and experiences with it. -Zachariah On Mar 27, 4:14 pm, Tin wrote: > Zachariah, > > Thanks for the word of encouragement!

[jQuery] Why isn't there any list widget?
I've searched extensively for a jquery widget that allows me to add/ remove items to a list, set font size, etc. For an example of what I mean, see here: http://www.webresourcesdepot.com/dnspinger/ Could anyone point me in the right direction?
[jQuery] [JQuery UI] Styles
i am wondering how can i create a button like the open dialog button in http://jqueryui.com/themeroller/ when i copy and paste the source for the button from the jqueryui site, i dun get the right positioning without editting the css. am i missing something? Open Dialog inline style="" are added by me. is there a documentation to tell me how i can replicate those buttons/link styles? trial and error is taking some time
[jQuery] Re: Using $.get with preload page seems to strip JavaScript
Just to clarify and update...
I've attempted to use the LiveQuery plugin (see code below) so that
elements that don't exist yet (that are getting retrieved via $.get)
get bound to the 'click' event, but that didn't change anything.
HTML pre-load page: test.html
Content page loaded via $.get: test.php
The JavaScript code I'm trying to get to work enables the "color theme
switcher" link on the top-right portion of the page. The code is:
jQuery('#switcher_wrapper > div').livequery('click', function() {
jQuery(this).siblings().removeClass();
jQuery(this).addClass('clr_picked');
if(this.id == 'org_blk') {
jQuery('#left').removeClass().addClass('org_blk');
jQuery('#right').removeClass().addClass('org_blk');
jQuery('#content').removeClass().addClass('content_org');
jQuery('body').removeClass();
jQuery('#subtitle').removeClass();
jQuery('#about').removeClass();
jQuery('#comments').removeClass();
jQuery('#blog').attr("src","feed.html");
}
if(this.id == 'org_solid') {
jQuery('#left').removeClass().addClass('org_solid');
jQuery('#right').removeClass().addClass('org_solid');
jQuery('#content').removeClass().addClass('content_org');
jQuery('body').removeClass();
jQuery('#subtitle').removeClass();
jQuery('#about').removeClass();
jQuery('#comments').removeClass();
jQuery('#blog').attr("src","feed.html");
}
if(this.id == 'org_grad') {
jQuery('#left').removeClass().addClass('org_grad');
jQuery('#right').removeClass().addClass('org_grad');
jQuery('#content').removeClass().addClass('content_org');
jQuery('body').removeClass();
jQuery('#subtitle').removeClass();
jQuery('#about').removeClass();
jQuery('#comments').removeClass();
jQuery('#blog').attr("src","feed.html");
}
if(this.id == 'blk_blk') {
jQuery('#left').removeClass().addClass('blk_blk');
jQuery('#right').removeClass().addClass('blk_blk');
jQuery('#content').removeClass().addClass('content_blk');
jQuery('body').removeClass().addClass('blk_bg_solid');
jQuery('#subtitle').removeClass().addClass('blk_bg_solid');
jQuery('#about').removeClass().addClass('blk_bg_solid');
jQuery('#comments').removeClass().addClass('blk_bg_solid');
jQuery('#blog').attr("src","feed_blk.html");
}
});
There are a couple of other jQuery and even Prototype events that
aren't working on the page, but hopefully I can figure those out on my
own after I get one working.
Thanks in advance for your help.

[jQuery] retrieving DOM element with specific CSS class
Hello guys, I'm trying to make some changes to the coda slider effect
on jqueryfordesigners.com
Basically what I want is changing the buttons every time I move from a
panel to an other one.
I have the code below:
FIRST
SECOND
THIRD
...
and the link to the current panel have the class 'selected'
Here the question: how can I retrieve the id of the link with the
class 'selected'?
I guess it should be something like: $('#slider .navigation').find
('a').XXX('selected').id but I don't know how to put in place of XXX.
Thanks

That's not something that the Cycle plugin will do for you. However, you could probably use the before/after callbacks to drive the appropriate behavior for a tooltip plugin, such as cluetip.

Well there must be more to the story than what you're telling us. The
code you've shown above looks fine. Perhaps there is a problem with
the json response.

No, not in the success function. But you can use the 'complete'
function to get access to the xhr.
complete: function(xhr, status) {
...
}

Just read the release notes for JQuery 1.3 as I was having a similar issue: "The '@' in [...@attr] has been removed. Deprecated since 1.2 this old syntax no longer works. Simply remove the @ to upgrade." The thickbox code on line 78 uses @rel to find all the gallery items with the same rel tag. If you remove the @ symbol it works with JQuery 1.3.2.
