Jquery Automatic Image Slider w/ CSS & jQuery

Question

This is Automatic Image Slider w/ CSS & jQuery by Soh Tanaka I am trying to customize it to show .desc when the mouse hover overs the slider but it does not seem to work any help?

//Set Default State of each portfolio piece
$(".paging").show();
$(".paging a:first").addClass("active");

//Get size of images, how many there are, then determin the size of the image reel.
var imageWidth = $(".window").width();
var imageSum = $(".image_reel ul.examples").size();
var imageReelWidth = imageWidth * imageSum;

//Adjust the image reel to its new size
$(".image_reel").css({'width' : imageReelWidth});

//Paging + Slider Function
rotate = function(){    
    var triggerID = $active.attr("rel") - 1; //Get number of times to slide
    var image_reelPosition = triggerID * imageWidth; //Determines the distance the image reel needs to slide

    $(".paging a").removeClass('active'); //Remove all active class
    $active.addClass('active'); //Add active class (the $active is declared in the rotateSwitch function)

    //Slider Animation
    $(".image_reel").animate({ 
        left: -image_reelPosition
    }, 500 );

}; 

//Rotation + Timing Event
rotateSwitch = function(){      
    play = setInterval(function(){ //Set timer - this will repeat itself every 3 seconds
        $active = $('.paging a.active').next();
        if ( $active.length === 0) { //If paging reaches the end...
            $active = $('.paging a:first'); //go back to first
        }
        rotate(); //Trigger the paging and slider function
    }, 7000); //Timer speed in milliseconds (3 seconds)
};

rotateSwitch(); //Run function on launch

//On Hover
$(".image_reel").hover(function() {
    clearInterval(play); //Stop the rotation
}, function() {
    rotateSwitch(); //Resume rotation
}); 

//Hide the tooglebox when page load
$(".desc").hide();
//slide up and down when hover over heading 2
$(".image_reel").hover(function(){
// slide toggle effect set to slow you can set it to fast too.
$(this).next(".desc").slideToggle("slow");
return true;
});


//On Click
$(".paging a").click(function() {   
    $active = $(this); //Activate the clicked paging
    //Reset Timer
    clearInterval(play); //Stop the rotation
    rotate(); //Trigger rotation immediately
    rotateSwitch(); // Resume rotation
    return false; //Prevent browser jump to link anchor
});

Hi!

I made a demo for you. But basically I had to move the description blocks outside of the image_reel block because it was being re-positioned and it would have been too much trouble to add scripting to position it properly.

So here is a summary of changes: Added CSS

.desc {
 display: none;
 position: absolute;
 top: 0;
 left: 0;
 z-index: 101;
 background: url(http://i45.tinypic.com/30w087b.png); /* 1x1 png with 70% opacity */
 color: #fff;
 font-size: 2em;
 padding: 10px;
 -moz-border-radius: 0 0 3px 0;
 -khtml-border-radius: 0 0 3px 0;
 -webkit-border-radius: 0 0 3px 0;
}

New Window Block

<div class="window">    
 <div class="image_reel">
  <a href="http://www.designbombs.com/tag/slider/"&gt;&lt;img src="reel_1.jpg" alt="" /></a>
  <a href="http://www.designbombs.com/tag/slider/"&gt;&lt;img src="reel_2.jpg" alt="" /></a>
  <a href="http://www.designbombs.com/tag/slider/"&gt;&lt;img src="reel_3.jpg" alt="" /></a>
  <a href="http://www.designbombs.com/tag/slider/"&gt;&lt;img src="reel_4.jpg" alt="" /></a>
 </div>
 <div class="descriptions">
  <div class="desc">blah blah blah 1</div>
  <div class="desc">blah blah blah 2</div>
  <div class="desc">blah blah blah 3</div>
  <div class="desc">blah blah blah 4</div>
 </div>
</div>

Script (Updated)

//slide up and down when hover over heading 2
$(".window").hover(function(){
    // slide toggle effect set to slow you can set it to fast too.
    $(".desc").eq( $('.paging a.active').attr("rel") - 1 ).slideDown("slow");
    return true;
}, function(){
    $(".desc").stop(true,true).slideUp('slow');
});

Since you don't show the HTML markup, I assume that '.desc' is a div containing some sort of caption. In any case, I don't see why you bind the hover twice, and also you need to run slideToggle in the unhover function. To do this you should change these lines:

//On Hover
$(".image_reel").hover(function() {
    clearInterval(play); //Stop the rotation
}, function() {
    rotateSwitch(); //Resume rotation
}); 

//Hide the tooglebox when page load
$(".desc").hide();
//slide up and down when hover over heading 2
$(".image_reel").hover(function(){
// slide toggle effect set to slow you can set it to fast too.
$(this).next(".desc").slideToggle("slow");
return true;
});

To this:

//Hide the tooglebox when page load
$(".desc").hide();

//On Hover
$(".image_reel").hover(function() {
    $(this).next(".desc").slideToggle("slow");
    clearInterval(play); //Stop the rotation
}, function() {
    $(this).next(".desc").slideToggle("slow");
    rotateSwitch(); //Resume rotation
});
