JavaScript Code
  1. <script type="text/javascript">  
  2. $(function (){  
  3.       
  4.     /* 用按钮控制图片左右滚动 */  
  5.     $(".hotPic .JQ-slide").Slide({  
  6.         effect:"scroolLoop",  
  7.         autoPlay:false,  
  8.         speed:"normal",

  10.         steps:1

除了jq库以外,还用了slide.js
