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-100',0,'
'); the...
