I have a carousel with small thumbnails beneath it. I am adding an .isActive class to show a hidden <div> that is positioned over each thumbnail. I can remove the .isActive class from the first thumbnail <div> when the carousel slides the first time. But I have not been able to add .isActive to the next <div>

How can I match the thumbnail that is selected with the corresponding slide?

Here is a fiddle: http://jsfiddle.net/gybYP/

Here is my HTML:

<div class="js-carousel">
  <div class="slidesContainer">
    <ul class="clearfix">
      <li class="slide green">One</li>
      <li class="slide blue">Two</li>
      <li class="slide red">Three</li>
    </ul>
  </div>
  <!-- /slidesContainer -->
  <div class="thumbnailContainer">
    <ul>
      <li class="thumb green">
        <div>
          <a href="#">
            <div class="smallSlide"></div>
            <div class="thumbOverlay isActive"></div>
          </a>
        </div>                                  
      </li>
      <li class="thumb blue">
        <div>
          <a href="#">
            <div class="smallSlide"></div>
            <div class="thumbOverlay"></div>
          </a>
        </div>
      </li>
      <li class="thumb red">
         <div>
          <a href="#">
            <div class="smallSlide"></div>
            <div class="thumbOverlay"></div>
          </a>
        </div>
      </li>
    </ul>
  </div>
  <!-- /thumbnailContainer -->
</div>
<!-- /js-carousel -->

Here's my CSS:

.clearfix:before,
.clearfix:after {
  content: "";
  display: table;
} 
.clearfix:after {
  clear: both;
}
.clearfix {
  zoom: 1; /* For IE 6/7 (trigger hasLayout) */
}

.slidesContainer {
  width:200px;
  height: 200px;
  overflow: hidden;
  margin-bottom: 10px;
 }

 .slidesContainer ul {
   margin: 0;
   padding: 0;
   width: 600px; /* Slides width times total slides */
   position: relative;
   top: 0;
   left: 0;
   list-style:none;
 }

.slide {
  width: 200px;
  height: 200px;
  float: left;
}

.green {background-color: green;}
.blue {background-color: blue;}
.red {background-color: red;}

.thumbnailContainer ul {
  margin: 0;
  padding: 0;
  width: 600px; /* Slides width times total slides */
  position: relative;
  top: 0;
  left: 0;
  list-style:none;
}
.thumb {
  width: 50px;
  height: 50px;
  display: inline-block;
  position: relative;
}

.thumbOverlay {
  background-color: gray;
  width: 20px;
  height: 20px;
  position: absolute;
  top: 30%;
  left: 30%;
  display: none;
}

.thumbOverlay.isActive {
  display: block;
}

Here is my JavaScript:

var slide_width = $('.slidesContainer li').outerWidth();

var left_value = slide_width * (-1);

$(document).ready(function() {

  var speed = 3000;
  var run = setInterval('rotate()', speed);

  $('.slide:first').before($('.slide:last'));

  //set the default item to the correct position 
  $('.slidesContainer ul').css({'left' : left_value});

  $('.slidesContainer').hover(

    function() {
      clearInterval(run);
    }, 
    function() {
      run = setInterval('rotate()', speed); 
    }
  ); 

});

function rotate() {
  //get the right position            
  var left_indent = parseInt($('.slidesContainer ul').css('left')) - slide_width;

  $('.slidesContainer ul').animate(
    {
      'left' : left_indent
    },
     200,
     function() {

       //Remove the class .isActive from the current active thumbnail
       $('.thumbnailContainer .thumbOverlay.isActive').removeClass('isActive');

       //move the first item and put it as last item
       $('.slidesContainer li:last').after($('.slidesContainer li:first'));                  

       //set the default item to correct position
       $('.slidesContainer ul').css({'left' : left_value});

     }
   );

}

带有 jquery-1.4.1.min.js 或更高版本的脚本端

<script type="text/javascript">
        var currentImage;
        var currentIndex = -1;
        var interval;

                        if (currentImage != indexImage) {
                            $(currentImage).css('z-index', 2);
                            clearTimeout(myTimer);
                            $(currentImage).fadeOut(0, function () {
                                myTimer = setTimeout("showNext()", 5000);
                                $(this).css({ 'display': 'none', 'z-index': 1 })                                
                            });
                        }

                    $(indexImage).css({ 'display': 'block', 'opacity': 1 });
                    currentImage = indexImage;
                    currentIndex = index;

CSS端

#push {

    padding-top:0px;
}
#wrapper{
    width:675px;

    height: auto !important;
    height: 96%;
    text-align:left;
    /*margin: 0 auto -30px;*/
    /*padding:0 10px 0px 10px;*/

.clearfix{
    clear:both;
    float:none;
