我要评论一段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。
