一：父页面js取得弹出窗口值
本页面用一个textbox接受传值
<input id="Text1" type="text" onclick="show();" runat="server" />
function show()
{
var result= window.showModalDialog("top.aspx",null,"dialogWidth:350px;dialogHeight:350px;help:no;status:no");
if (result)
{
var a = document.getElementById("Text1");
a.value=result;
//alert(result);
}
else
{
alert('子窗口返回假!');
}
}
弹出窗口页面
在页面添加 <base target="_self"></base>
返回传值用
string a = "传值成功";
Response.Write( "<script>window.returnValue='" +a+ "';window.close();</script>" );
二：弹出窗口关闭，刷新父页面
父页面
<script type="text/javascript">
function show()
{
//弹出窗口方法1：
//window.showModalDialog("Default3.aspx",null,"dialogWidth:350px;dialogHeight:350px;help:no;status:no");
//弹出窗口方法2：
window.open("Default3.aspx",null,"toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,width=400,height=200,left=300,top=400");
/ }
</script>
弹出页面
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>无标题页</title>
<base target="_self"></base>
</head>
<body >
<form id="form1" runat="server">
<div>
弹出页面
<asp:Button ID="Button2" runat="server" OnClick="Button2_Click" Text="Button" /></div>
</form>
</body>
</html>
代码：
protected void Button2_Click( object sender, EventArgs e )
{
Response.Write( "<script>window.opener.location.reload();window.close();</script>" );
}
刷新框架父页面
Response.Write("<script>window.open('err.aspx','');window.parent.location.reload();</script>");
