现在很多网站广告做的如火如荼,现在我就来介绍一下常见的对联浮动广告效果的代码使用方法,介绍的这种效果,在1024*768分辨率下正常显示,在800*600的分辨率下可以自动隐藏,以免遮住页面影响访问者浏览内容,下面就是实现效果所需代码:


  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++)<
