主要代码：
注意这段代码 是子页面中添加的也就是弹出的那个页面刷新父页面
??<script type="text/javascript"> ???????function shuaxin() { ???????????try { ???????????????window.parent.opener.location.reload(); ???????????????window.parent.close(); ???????????} catch (e) { ???????????????window.parent.opener.location = "http://localhost:32859/test.aspx"; ???????????????window.parent.opener = null; ???????????????window.parent.close(); ???????????} ???????} ???</script>测试demo
首先新建一个web1，再新建一个test.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="WebApp02.test" %><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> ???<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> ???<title></title> ???<script type="text/javascript"> ???????function OpenPage() { ???????????window.open(‘http://localhost:32858/testweb2.aspx‘, ‘newwindow‘, ‘height=100,width=400,top=0,left=0,toolbar=no,menubar=no,scrollbars=no,resizable=no,location=no,status=no‘) ???????} ???</script></head><body> ???<form id="form1" runat="server"> ???????<div> ???????????<asp:Label ID="lblTest" runat="server" Text="还没开始测试"></asp:Label> ???????????<input id="Button1" type="button" value="button" onclick="OpenPage()" /> ???????</div> ???</form></body></html>test.aspx 后台代码：
using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;namespace WebApp02{ ???public partial class test : System.Web.UI.Page ???{ ???????protected void Page_Load(object sender, EventArgs e) ???????{ ???????????if (IsPostBack) ???????????{ ???????????????lblTest.Text = "页面执行时间：" + DateTime.Now.ToLocalTime(); ???????????} ???????????Load(); ???????} ???????public void Load() ???????{ ???????????lblTest.Text = "页面执行时间：" + DateTime.Now.ToLocalTime(); ???????} ???}}再次新建一个web2，再新建一个testweb2.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="testweb1.aspx.cs" Inherits="WebApp01.testweb1" %><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> ???<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> ???<title></title> ???<script type="text/javascript"> ???????function shuaxin() { ???????????try { ???????????????window.parent.opener.location.reload(); ???????????????window.parent.close(); ???????????} catch (e) { ???????????????window.parent.opener.location = "http://localhost:32859/test.aspx"; ???????????????window.parent.opener = null; ???????????????window.parent.close(); ???????????} ???????} ???</script></head><body> ???<form id="form1" runat="server"> ???????<div> ???????????<input id="Text1" type="button" value="关闭当前页面" onclick="shuaxin()" /> ???????</div> ???</form></body></html>参考文章：http://www.xuebuyuan.com/838707.html
