一：父页面js取得弹出窗口值
本页面用一个textbox接受传值
<input %>
<!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 /></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>");
