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：

rush:js;"> var delta=0.15 var collection; function floaters() { this.items = ; this.addItem = function(id,x,y,content) { document.write('

');

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,'');
theFloaters.addItem('followDiv2',12,'');
theFloaters.play();
