2。控制<divid="right_mid">随滚动条移动

<divid="right_mid">

<imgid="close"src="<%=basePath%>/home/img/seckilling/close.gif"style="position:absolute;margin:-60px10px0140px;"onclick="onCloseOntice()"/>

<s:iteratorvalue="orderdetailList">

<divclass="notice_text">

<s:propertyvalue="order.members.membersName"/>

在<s:datename="order.orderTime"format="HH:mm:ss"></s:date>

成功秒杀<s:propertyvalue="shopping.sname"/>

</div>

</s:iterator>

</div>

3。实现滚动的js代码

$(document).ready(function(){

$("#right_mid").css("top",460+$(document).scrollTop());

$(window).scroll(function(){

$("#right_mid").css("top",200+$(document).scrollTop());

});

});
