54、图片集旋转显示

脚本说明:

第一步:把如下代码加入<body>区域中

<script type="text/javascript">

       var Car_NoOfSides=8;          // must be 4, 6, 8 or 12

       For 4 sided carousel specify at least 2 images

       For 6 sided carousel specify at least 3

       function C_Rstrt(){C_Stppd=false}

</script>

<div id="Carousel" style="position:relative">

   <img src="200310171/placeholder.gif" width="371" height="225">

 

 

 

第二步:把<body>中的内容改为:

<body onload="Carousel()">
