Hi,
I am trying recreate the following type of scrolling thumbnail navigation as described in the following tutorial:
http://tympanus.net/codrops/2010/05/10/scrollable-thumbs-menu/
I require my thumbs to slide out horizontally from the
left. I have amended the code to the best of my abilities, but I can't get it to work. (Think the problem is in the top third of the jquery).
Here is what I have to date:
HTML
<ul class="menu" id="menu">
<li>
<a href="#"></a>
<div class="sc_menu_wrapper">
<div class="sc_menu">
<a href="#"><img src="images/gallery/1.jpg" alt=""/></a>
<a href="#"><img src="images/gallery/2.jpg" alt=""/></a>
<a href="#"><img src="images/gallery/3.jpg" alt=""/></a>
<a href="#"><img src="images/gallery/4.jpg" alt=""/></a>
<a href="#"><img src="images/gallery/5.jpg" alt=""/></a>
</div>
</div>
</li>
</ul>
CSS
/* Navigation Style */
ul.menu{
position: fixed;
top: 0px;
left:0px;
width: 100%;
}
ul.menu li{
position:relative;
width: 100%
}
ul.menu li > a{
position:absolute;
top:300px;
left:0px;
width:40px;
height:200px;
background-color:#e7e7e8;
}
/* Thumb Scrolling Style */
div.sc_menu_wrapper {
position: absolute;
right: 0px;
height: 220px;
overflow: hidden;
top: 300px;
left:0px;
visibility:hidden;
}
div.sc_menu {
height: 200px;
visibility:hidden;
}
.sc_menu a {
display: block;
background-color:#e7e7e8;
}
.sc_menu img {
display: block;
border: none;
opacity:0.3;
filter:progid:DXImageTransform.Microsoft.Alpha(opacity=30);
}
JQUERY
$(function(){
// function to make the thumbs menu scrollable
function buildThumbs($elem){
var $wrapper = $elem.next();
var $menu = $wrapper.find('.sc_menu');
var inactiveMargin = 220;
// move the scroll down to the beggining (move as much as the height of the menu)
$wrapper.scrollRight($menu.outerHeight());
//when moving the mouse up or down, the wrapper moves (scrolls) up or down
$wrapper.bind('mousemove',function(e){
var wrapperWidth = $wrapper.width();
var menuWidth = $menu.outerWidth() + 2 * inactiveMargin;
var top = (e.pageX - $wrapper.offset().right) * (menuWidth - wrapperWidth) / wrapperWidth - inactiveMargin;
$wrapper.scrollRight(right+10);
});
}
var stacktime;
$('#menu li > a').bind('mouseover',function () {
var $this = $(this);
buildThumbs($this);
var pos = $this.next().find('a').size();
var f = function(){
if(pos==0) clearTimeout(stacktime);
$this.next().find('a:nth-child('+pos+')').css('visibility','visible');
--pos;
};
// each thumb will appear with a delay
stacktime = setInterval(f , 50);
});
/// on mouseleave of the whole <li> the scrollable area is hidden
$('#menu li').bind('mouseleave',function () {
var $this = $(this);
clearTimeout(stacktime);
$this.find('.sc_menu').css('visibility','hidden').find('a').css('visibility','hidden');
$this.find('.sc_menu_wrapper').css('visibility','hidden');
});
// when hovering a thumb, change its opacity
$('.sc_menu a').hover(
function () {
var $this = $(this);
$this.find('img')
.stop()
.animate({'opacity':'1.0'},400);
},
function () {
var $this = $(this);
$this.find('img')
.stop()
.animate({'opacity':'0.3'},400);
}
);
});
Wondering if some eagle eye might be able to point out where I am going wrong. As my knowledge of JQuery is limited, I'm guessing it is in there.
I really appreciate anyone taking the time to look this over.
Thank you!
