js 左右悬浮对联广告代码示例

一段js 左右悬浮广告代码，只要修改广告图片地址与连接地址，相应参数根据页面调整下就可以使用这段左右悬浮广告代码了

代码：

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'?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.body.scrollLeft+followObj_x)) {   var dx=(document.body.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.body.scrollTop+followObj_y)) {   var dy=(document.body.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(); 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();

另存为*.js文件，在页面中引用：<script src="*.js"></script>调用即可，*代表你另存的文件名！

注意：修改广告图片地址和连接地址！相应的参数可以根据页面自行调整。
