时尚前沿的图片左右滚动效果-2

1.增加动态效果

    在滚动区域外围包裹如下HTML

 1 <div class="rollBox">
 2      <div class="Cont" id="ISL_Cont">
 3       <div class="ScrCont">
 4        <div id="List1">
 5   
 6        <!--滚动区域开始-->
 7            ......
 8        <!--滚动区域结束-->
 9         
10        </div>
11        <div id="List2"></div>
12       </div>
13     </div>
14  </div>
15 
16 <!--左右切换按扭结束-->
17     <a href="#" class="dirl"  onmousedown="ISL_GoUp()" onmouseup="ISL_StopUp()" onmouseout="ISL_StopUp()"></a>
18     <a href="#" class="dirr" onmousedown="ISL_GoDown()" onmouseup="ISL_StopDown()" onmouseout="ISL_StopDown()"></a>
19 <!--左右切换按扭结束-->

    新增css 样式（可以作为模板）

1  /*滚动样式*/
2  .rollBox{width:1000px;overflow:hidden;}
3  .rollBox .Cont{width:1000px;overflow:hidden;float:left;}
4  .rollBox .ScrCont{width:10000000px;}
5  .rollBox #List1,.rollBox #List2{float:left;}
