制作弹出层

//最近在做一个公司博客，页面上用到了很多弹出层，于是大家就仿照着其他网站上的弹出层做了一个。
<script type="text/javascript" src="/blogsystem/web/common/js/jquery-1.3.2.min.js"></script> 
<script type="text/javascript" src="/blogsystem/web/common/js/jquery-ui-1.7.2.custom.min.js"></script>

<!--弹出层-->
<div id="background"></div>
<div id="outDiv">
    <div id="outTitle">
         <span id="titleLayer">提示</span>
         <div id="closeLayer" class="closeLayer"></div>
    </div>
    <div id="outContent">
    	 <img src="/blogsystem/web/image/album_wen.gif" align="middle"/>确定要删除此好友吗？
    </div>
    <div id="outBottom">
         <input type="submit" value="确认" onclick="delFriends('<s:property value="#del"/>')"/>　　
         <input type="button" value="取消"  class="closeLayer"/>
    </div>
</div>

//页面弹出层样式

				$("#outDiv").css("display","none");

        })
 //删除好友
function delFriends(url){
        window.location.href=url;
}
