楼主怎么连续发了4贴啊？应该最多3贴吧？
帮你顶一下，优化接着说：）我自己的帖子早就顶不动了：http://hi.csdn.net/link.php?url=http://topic.csdn.net%2Fu%2F20100125%2F22%2Fc0c0a3bb-d7ab-43a1-b210-2b05ae1b1d97.html

我做过类似功能，只不过位置保存数据库中了。其实改起来也应该挺容易的，在进入页面后，重新load这些portlet的时候记住他们是否关闭，要一个重新绘制的过程就OK了。

save:function(name, value, hours){
        var expire = "";
        if(hours != null)
        {
        expire = new Date((new Date()).getTime() + hours * 3600000);
        expire = "; expires=" + expire.toGMTString();
        }
        document.cookie = name  + "=" + escape(value) + expire;
    },
没有设置保存路径?
