jQuery图片切换

效果如http://河池手机网.com 的banner的效果。

jQuery代码如下：

<script type="text/javascript">
    $(function(){
         $("#bannerwenzi").each(function(){
                      $("#bannerdv a:eq(0)").show();
                            $("#bannerwenzi div").click(function(){
                                  $(this).addClass("bwenzishow").siblings("div").removeClass("bwenzishow");
                                   $("#bannerpic a:eq("+$(this).index()+")").show().siblings("a").hide();
                            });
                            
                        });
         xx=0;    
         function setTab() {
            $("#bannerwenzi div:eq("+xx+")").addClass("bwenzishow").siblings("div").removeClass("bwenzishow");
              $("#bannerpic a:eq("+xx+")").show().siblings("a").hide();
                    xx+=1;
                   if(xx>3) xx=0;
                
          }
        var  jiange=6000;
           timerID=setInterval(setTab,jiange);
         $("#bannerpic").mousemove(function(){
             clearInterval(timerID);
           
         }).mouseout(function(){
             timerID=setInterval(setTab,jiange);
         });    
         
          $("#bannerwenzi").mousemove(function(){
             clearInterval(timerID);
           
         }).mouseout(function(){
             timerID=setInterval(setTab,jiange);
         });    
             
    });
    </script>

html的部分代码：

<div id="bannerdv">
     <div id="bannerpic">
