源码如下：
<style type="text/css">*{margin:0;padding:0;}body{height:2000px;}.floatAd{width:124px;height:299px; text-align:center; position:fixed;margin-left:0;top:109px; _position:absolute; background:url(//files.VeVB.COm/demoimg/2014/bg_slide2_120_270.png) no-repeat;}.floatAd a{display:block;}.floatAd img{border:none;}.floatAd .closeAd{width:50px; height:20px; display:block; cursor:pointer;margin:9px 0 0 auto;}.flAd{left:0;}.frAd{right:0;}</style><div><a href="#" target="_blank"><img src="#"></a><span></span></div><div><a href="#" target="_blank"><img src="#"></a><span></span></div><script type="text/javascript">$(".closeAd").click(function(){ $(this).parent(".floatAd").hide();})/*for ie6*/function scrollAd(obj) {var obj = "." + obj;var adTop = $(".floatAd").offset().top;//alert(adTop);$(window).scroll(function () {$(".floatAd").css({top : $(window).scrollTop() + adTop})})}$(function () {//针对ie6，模拟position:fixed效果if ($.browser.msie && parseInt($.browser.version) == 6) {scrollAd("floatAd");}})</script>我们还可以改下代码，实现“单边展示飘浮广告，多个广告轮播展示”的效果，更改后的源代码：
<style type="text/css">*{margin:0;padding:0;}body{height:2000px;}.floatAd{width:124px;height:299px; text-align:center; position:fixed;margin-left:0;top:109px;right:0; _position:absolute; background:url(//files.VeVB.COm/demoimg/2014/bg_slide2_120_270.png) no-repeat;}.floatAd a{display:block;}.floatAd img{border:none;}.floatAd .closeAd{width:50px; height:20px; display:block; cursor:pointer;margin:9px 0 0 auto;}</style><div><a href="#" target="_blank"><img src="#"></a><a href="#" target="_blank" style="display:none;"><img src="#"></a><span></span></div><script type="text/javascript">$(".closeAd").click(function(){ $(".floatAd").hide();})/*隔时切换飘浮广告*/function changePic(obj,times){var num=0,obj =$("." + obj+" >a"),times=times*1000,len=obj.length;//alert(len);setInterval(function(){num++;num=num>len-1?0:num;//console.log(num);$(obj).eq(num).show().siblings("a").hide();},times)}/*for ie6*/function scrollAd(obj) {var obj = "." + obj;var adTop = $(".floatAd").offset().top;//alert(adTop);$(window).scroll(function () {$(".floatAd").css({top : $(window).scrollTop() + adTop})})}$(function () {//针对ie6，模拟position:fixed效果if ($.browser.msie && parseInt($.browser.version) == 6) {scrollAd("floatAd");}//执行定时切换图片广告changePic("floatAd",2);//每隔2秒切换一次广告图片展示，间隔时间可控})</script>
