前提条件：B页面是由A页面打开的。
方法：
在A页面的前台代码中加入以下代码：
<script language="javascript">function DownDvasp(htmlurl){var
newwin=window.open(htmlurl,'','toolbar=no,location=no,directories=no,status=no,menub
ar=no,scrollbars=no,resizable=no');return false;}</script>
此代码如果在继承母版页的asp.net页面中就需要加在<asp:Content ID="Content1"
ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">行下。
如果在一般的asp.net页面中就需加在<HEAD>段中。
然后在需链接打开的位置加入：
<a href="B.aspx?id=<%# Eval("id")%>" onclick="return DownDvasp(this.href);">回复此留
言</a>
这样单击此链接就可打开一个窗口了。
在B页面的前台代码中加入以下代码：
<input type='button' value='关闭窗口'
onclick='javascript:window.opener.location.href="A.aspx";window.close();''>
这样就实现了关闭B窗口的同时重新刷新A窗口的目地。
若只是关闭窗口而不需重新刷新A窗口，只需改成onclick='window.close()'就行了。

# re: 如何在asp.net中关闭B页面时，自动刷新A页面？ 2006-09-11 12:02 what
假设分别是1.asp和2.asp
------1.asp
..
..
..
<form action=2.asp method=post>
.
</form>
----------2.asp
<meta http-equiv="refresh" content="2; url=1.asp"> '不要忘记在head区加这句
<%
if request("txtn1")<>"" then
for i=1 to cint(request("txtn1"))
s="delete from cyprice where id = " & trim(request("txtep1" & cstr(i)))
rs.open s,conn,3,2
next
response.redirect "cyjc.asp"
end if
%>
在由2.asp转回1.asp的时候刷新了1.asp。
=====================================================================================
使用window.location.reload;刷新时，如果提交数据的动作，则会出现这么个讨厌的对话框！
解决此问题，应该这样写：
window.location.href=window.location.href;
window.location.reload;
同理，如果是刷新父窗口，应该这样写：
window.opener.location.href=window.opener.location.href;
window.location.reload;
这种写法就不出现那讨厌的对话框啦！
