js 左右懸浮對聯廣告程式碼範例_佈局與層

一段js 左右懸浮廣告代碼，只要修改廣告圖片地址與連接地址，相應參數根據頁面調整下就可以使用這段左右懸浮廣告代碼了

代碼：

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();
