</style>
<div class="floatAd flAd">
<a href="#" target="_blank"><img src="#" width="120" height="270" alt="第1张图"></a>
<span class="closeAd"></span>
</div>
<div class="floatAd frAd">
<a href="#" target="_blank"><img src="#" width="120" height="270" alt="第2张图"></a>
<span class="closeAd"></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:
