var delta=0.15
var collection;
function floaters() {
this.items = [];
this.addItem = function(id,x,y,content)
{
document.write('
'+content+'
');
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;i0?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-105',20,'');
theFloaters.addItem('followDiv2',10,20,'');
theFloaters.play();
