对联广告代码效果之一[普通效果]

       此刻很多网站告白做的热火朝天，此刻我就来引见一下罕见的春联浮动告白功效的代码运用本领，正文引见的这种功效，在1024*768辨别率下平常表露，在800*600的辨别率下不妨机动湮没，免得遮住页面感化考察者欣赏实质，底下文本框中即是实行功效所需代码：

    var delta=0.015    var collection;    function floaters() {        this.items    = [];        this.additem    = function(id,x,y,content)                  {                    document.write('<div id='+id+' style="z-index: 0; 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-100',0,'</a><br><a href=告白链接地方 target=_blank><img src=告白图片地方 width=100 height=400 border=0></a>');    thefloaters.additem('followdiv2',0,0,'<br><a href=告白链接地方 target=_blank><img src=告白图片地方 width=100 height=400 border=0></a>');    thefloaters.play(); 

把上头的代码另存为一个js文献，而后在想实行此功效的页面用 挪用即可！提防窜改告白图片地方和贯穿地方！
