JavaScript - How To Fadeout?

Hi Guys,

I'm using jcarousellite to show my newsitems in a vertical carousel.
http://www.gmarwaha.com/jquery/jcarousellite/

The carousel itself works perfectly, now I'm trying to add that before the news scrolls upwards the top news-item fades-out first.

Now it is fading out the complete list and I simply can't seem to figure out how to 'talk' to the 'active/top' <li> in the list.


Can someone give me a hint?

Thanks in advance,
Marcel


-- Code Below --

Code:

$(function() {
	$(".widgetCarousel").jCarouselLite({
		circular: true,
		vertical: true,
		visible: 3,
		scroll: 1,
		start: 1,
		auto: 500,
		speed: 1000,
		beforeStart: function(a) {
			$(a).parent().fadeTo(100, 0);
    		},
		afterEnd: function(a) {
			$(a).parent().fadeTo(100, 1);
		}
    	});

});

<div class="widgetCarousel">
	<ul>
		<li>My very own news item</li>
		<li>My very own news item</li>
		<li>My very own news item</li>
		<li>My very own news item</li>
		<li>My very own news item</li>
		<li>My very own news item</li>	
	</ul>	
</div>

How can I add fadeIn and fadeOut with a duration that I can set/adjust to this javascript?
The site is using Zencart and the the Image Hover effect comes from the Image Handler 2 Add-on.

Thank you in advance for your help. Your time and attention in helping me with this is greatly appreciated.

Here is a link to the site residing on a subdomain I use to build sites on http://test3.fullspecweb.com

I read the "Read Before Posting" and it said to only post the code you are having trouble with, but I have no idea which section that would be so I apologize for being such a noob

Here is the script from the jscript_imagehover.js file...
Code:

var offsetfrommouse=[20,20]; //image x,y offsets from cursor position in pixels. Enter 0,0 for no offset
var displayduration=0; //duration in seconds image should remain visible. 0 for always.
var currentimageheight = 400;    // maximum image size.
var padding=10; // padding must by larger than specified div padding in stylessheet

// Global variables for sizes of hoverimg
// Defined in "showtrail()", used in "followmouse()"
var zoomimg_w=0;
var zoomimg_h=0;
var vpos;
//Detect IE
var stIsIE = /*@cc_on!@*/false;
//detect opera
var isOpera =
    window.opera?1:0;
// Detect Webkit browsers
var isWebKit =
  navigator.userAgent.indexOf("AppleWebKit") > -1;

Is it possible to have a form's textarea background image fadeout to an alternate bg image, when that textarea is selected (by clicking the textarea or tabbing to it)? I've never seen this done before, but I'd really like to do it..

I've got a <ul> w/ 6 <li> items and CSS to make them 104x228 side blocks, which hold 2 images, one on top of the other. The 6 rows of images look like this:

X X X X X
X X X X X

This is what I want: The top row of images to be opacity:0 (or hidden), and then when you mouseover the bottom images, the top images come to 100 opacity. When you mouseout, the opacity is back to 0.

Here's the HTML and CSS:

Code:

<ul class="carz">
<li><img src="img/impreza2.jpg" class="imgtophidden"/><img src="img/impreza.jpg" /></li>
<li><img src="img/wrx.jpg" class="imgtophidden"/><img src="img/wrx.jpg" /></li>
<li><img src="img/legacy2.jpg" class="imgtophidden"/><img src="img/legacy.jpg" />/li>
<li><img src="img/outback2.jpg" class="imgtophidden"/><img src="img/outback.jpg" /></li>
<li><img src="img/forester2.jpg" class="imgtophidden"/><img src="img/forester.jpg" /></li>
<li><img src="img/tribeca2.jpg" class="imgtophidden"/><img src="img/tribeca.jpg" /></li>
</ul>

The classes are like so:

Code:

.imgtophidden {
opacity: 0;
}
.imgtop {
opacity: 100;
}

I am new to jQuery coding (but loving learning) and I want to figure out: how do I make this in jQuery? Here's what I have so far:

Code:

$(function() {
$("ul.carz li").hover(function() {
	$(this).find('img.imgtophidden').addClass('imgtop')
	} , function() {
	$(this).find('img.imgtop').addClass('imgtophidden')
});
});
