A js left and right floating ad code, as long as you modify the ad image address and connection address, and adjust the corresponding parameters according to the page, you can use this left and right floating ad code

Code:

var delta=0.15
 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'&#63;eval(x):x)+';top:'+(typeof(y)=='string'&#63;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'&#63;eval(collection[i].x):collection[i].x);
  var followObj_y = (typeof(collection[i].y)=='string'&#63;eval(collection[i].y):collection[i].y);
  if(followObj.offsetLeft!=(document.body.scrollLeft+followObj_x)) {
   var dx=(document.body.scrollLeft+followObj_x-followObj.offsetLeft)*delta;
   dx=(dx>0&#63;1:-1)*Math.ceil(Math.abs(dx));
   followObj.style.left=followObj.offsetLeft+dx;
   }
  if(followObj.offsetTop!=(document.body.scrollTop+followObj_y)) {
   var dy=(document.body.scrollTop+followObj_y-followObj.offsetTop)*delta;
   dy=(dy>0&#63;1:-1)*Math.ceil(Math.abs(dy));
   followObj.style.top=followObj.offsetTop+dy;
   }
  followObj.style.display = '';
  }
 } 
 
 var theFloaters = new floaters();
 theFloaters.addItem('followDiv1','document.body.clientWidth-112',230,'<a href=左链接地址 target=_blank><img src=左图片地址 border=0></a>');
 theFloaters.addItem('followDiv2',12,230,'<a href=右链接地址 target=_blank><img src=右图片地址 border=0></a>');
 theFloaters.play();
