   代码如下: <p> <meta content="text/html; charset=gb2312" http-equiv="Content-Type" /><style type="text/css">   .shuoming {margin-top:20px; border:1px solid #ccc; padding-bottom:10px; width:600px; margin:0 auto;} .shuoming dt {height:30px; line-height:30px; font-weight:bold; text-indent:10px;} .shuoming dd {line-height:20px; padding:5px 20px;}</style></p> <script language=JavaScript >  var delta=0.08  var collection;  function floaters() {   this.items = [];   this.addItem = function(id,x,y,content)       {      document.write('<DIV id='+id+' style="Z-INDEX: 10; POSITION: absolute;  width:80px; height:60px;left:'+(typeof(x)=='string'?eval(x):x)+';top:'+(typeof(y)=='string'?eval(y):y)+'">'+content+'</DIV>');        var newItem    = {};      newItem.object   = document.getElementById(id);      newItem.x    = x;      newItem.y    = y;        this.items[this.items.length]  = newItem;       }   this.play = function()       {      collection    = this.items      setInterval('play()',10);       }   }   function play()   {      for(var i=0;i<collection.length;i++)    {     var followObj  = collection[i].object;     var followObj_x  = (typeof(collection[i].x)=='string'?eval(collection[i].x):collection[i].x);     var followObj_y  = (typeof(collection[i].y)=='string'?eval(collection[i].y):collection[i].y);       if(followObj.offsetLeft!=(document.documentElement.scrollLeft+followObj_x)) {      var dx=(document.documentElement.scrollLeft+followObj_x-followObj.offsetLeft)*delta;      dx=(dx>0?1:-1)*Math.ceil(Math.abs(dx));      followObj.style.left=followObj.offsetLeft+dx;      }       if(followObj.offsetTop!=(document.documentElement.scrollTop+followObj_y)) {      var dy=(document.documentElement.scrollTop+followObj_y-followObj.offsetTop)*delta;      dy=(dy>0?1:-1)*Math.ceil(Math.abs(dy));      followObj.style.top=followObj.offsetTop+dy;      }     followObj.style.display = '';    }   }     var theFloaters  = new floaters();  //右面  theFloaters.addItem('followDiv1','document.documentElement.clientWidth-106',80,'<img src=http://pic.jb51.net/sudu.gif id=ad />');  //左面  theFloaters.addItem('followDiv2',6,80,'<img src=http://pic.jb51.net/sudu.gif id=ad />');  theFloaters.play();   //图片格式调用方法 //<a href=http://www.jb51.net.net/ target=_blank><img  src=http://pic.jb51.net/sudu.gif border=0></a>   </script> <table border="0" cellspacing="0" cellpadding="0" width="778" bgcolor="#f4f4f4" align="center" height="1500">     <tbody>         <tr>             <td valign="top" align="center"><br />             <dl class="shuoming"></dl></td>         </tr>     </tbody> </table>
