请教大家一个问题？
我在Frontpage里测试代码。没有任何错误。可在IE浏览时提示对象不支持此属性或方法？怎么会这样的哦？
下面的代码：
<!--#include file="Conn.ASP"-->
<!--include file="char.inc"-->
<!--#include file="chkuser.asp" -->
<%
id=request("id")
if id="" then
id=0
else
id=id
end if

在Frontpage里测试代码没有错误。在IE浏览的时候提示这行var newTR = DataTr.cloneNode(true);对象不支持此属性或方法
麻烦高手看看。这是为什么？
