关于createElement，试了很长时间还是不行，请高手指点
需要做资格用户列表，我在页面中定时检测一些用户是否在线，如果在线其用户名可以点击连接，不在线的用户名称变为灰色，用户名不可连接。
代码如下
<HTML>
<HEAD>

window.setTimeout(GetVIPList_Online, 10000);

<script>
----^^^^^^^^------------这里应该是</script>

那里是</script>，是我写错了。代码倒是不出错，但是页面中的div应该只有十个，但是现在每隔一段时间就增加了十个。我是想将以前加入的div不可见，上述代码不能实现。Top

你这样的问题最好是对某个特定的容器的 innerHTML 进行清除和写入。Top
