标题 JS实现的多张图片轮流播放幻灯片效果
内容
    本文实例讲述了JS实现的多张图片轮流播放幻灯片效果。分享给大家供大家参考，具体如下：
    <body>
    <script language="javascript" type="text/javascript">
    <!--
    /**************************************************
    名称: 图片轮播类
    创建时间: 2010-07-11  zhangty
    示例:
      页面中已经存在名为imgPlayer(或者别的ID也行)的节点.
      PImgPlayer.addItem( "test", "http://www.pomoho.com", "/uploads/202504/02/logo52855.jpg);BR      PImgPlayer.addItem( "test2", "http://www.pomoho.com.cn", "/uploads/202504/02/logo42855.jpg);BR      PImgPlayer.addItem( "test3", "http://www.pomoho.com.cn", "/uploads/202504/02/logo32855.jpg);BR      PImgPlayer.init( "imgPlayer", 200, 230 );
    备注:
      适用于一个页面只有一个图片轮播的地方.
