类似新浪首页两边漂浮的广告图片，随滚动条上下移动，兼容1024和768窗口   <script> 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() { if(screen.width<=800) { for(var i=0;i<collection.length;i++) { collection[i].object.style.display = 'none'; } return; } 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-106',80,'<a href=# target=_blank><img src=/img/200406301.jpg border=0></a> <a href=# target=_blank><img src=/img/200406301.jpg border=0>'); theFloaters.addItem('followDiv2',6,80,'<a href=# target=_blank><img src=/img/200406301.jpg border=0></a> <a href=http://www.knowsky.com target=_blank><img src=/img/200406302.jpg border=0> '); theFloaters.play(); </script>
