可以返回值的弹出窗口:用的是window.showModalDialog()方法. window.showModalDialog(URL,dialogArgments.features) 打开一个新窗口
当弹出窗口关闭的时候就能得到返回值,下面有个简单的例子:
开发环境: Visual Studio.Net 2003(C#) + IE6.0
A.aspx
<SCRIPT LANGUAGE=JAVASCRIPT>
function btnGetReturnValue_onclick()
{
var temp= window.showModalDialog("B.aspx","","center=yes;help=no;status=no");
document.Form1.TextBox1.value = temp;
}
</SCRIPT>
.......
<Input Type="Button" id=" btnGetReturnValue" onclick="return btnGetReturnValue_onclick() value="获取">
B.aspx.cs
在你想操作的事件中加上
string str = "返回值"
Response.Write("<script language=javascript>window.returnValue ="+str+";window.close()</script>");
我的测试:
test.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="test.aspx.cs" Inherits="test" %>

function btnGetReturnValue_onclick()
{
var temp= window.showModalDialog("testopen.aspx","","center=yes;help=no;status=no");
if (temp!=undefined)
{
document.Form1.TextBox1.value = temp;
}
else
{
document.Form1.TextBox1.value = "null";
}
}
</SCRIPT>
