例子：
以下是父页的html代码
<%@ page language="vb" autoeventwireup="false" codebehind="main.aspx.vb" inherits="zero.main"%>
<!doctype html public "-//w3c//dtd html 4.0 transitional//en">
<html>
<head>
<title>main</title>
<meta name="generator" content="microsoft visual studio .net 7.1">
<meta name="code_language" content="visual basic .net 7.1">
<meta name="vs_defaultclientscript" content="javascript">
<meta name="vs_targetschema" content="http://schemas.microsoft.com/intellisense/ie5">
<script language="javascript" charset="gb2312">
function searchvalue()
{
var sql="select * from companyjob";
setcookie("sendsql",sql);
var url="child.aspx";
window.open(url,'_blank');
}
function setcookie(name, value)
{
document.cookie = name + "=" + value;
}
</script>
</head>
<body ms_positioning="gridlayout" >
<form id="form1" method="post" runat="server">
<input id="hidden1" style="z-index: 101; left: 8px; position: absolute; top: 8px" type="hidden"
name="hidden1" runat="server"><input style="z-index: 102; left: 96px; position: absolute; top: 144px" type="button" onclick="searchvalue();"
value="open" id="button1" name="button1">
<asp:button id="button2" style="z-index: 103; left: 256px; position: absolute; top: 152px" runat="server"
text="button"></asp:button>
</form>
</body>
</html>
child 页[子页]
<%@ page language="vb" autoeventwireup="false" codebehind="child.aspx.vb" inherits="zero.child"%>
<!doctype html public "-//w3c//dtd html 4.0 transitional//en">
<html>
<head>
<title>child</title>
<meta name="generator" content="microsoft visual studio .net 7.1">
<meta name="code_language" content="visual basic .net 7.1">
<meta name="vs_defaultclientscript" content="javascript">
<meta name="vs_targetschema" content="http://schemas.microsoft.com/intellisense/ie5">
<script language =javascript >
function getv()
{
alert(document.forms("hidden1"));
document.all("hidden1").value=document.forms("hidden1");
}
</script>
</head>
<body ms_positioning="gridlayout" >
<form id="form1" method="post" runat="server">
<input style="z-index: 101; left: 8px; position: absolute; top: 8px" type="hidden" id="hidden1"
name="hidden1" runat="server"></font>
</form>
</body>
</html>
.vb文件
if not ispostback then
'response.write(request.form("hidden1"))
dim cookie as httpcookie = request.cookies("sendsql")
if not cookie is nothing then
response.write(cookie.value)
end if
end if
2。是思归大哥介绍的方法
在父页中加入一个非runat=server的form表单，用来提交隐藏控件的值到子页
<form method="post" target="_blank" id="form2">
<input type=hidden name="query">
</form>
<script language="javascript">
function searchvalue()
{
var sql="select * from companyjob";
document.all.form2.query.value=sql;
document.all.form2.action="child.aspx";
document.all.form2.submit();
}
</script>
子页的后台代码中 (.vb)
在page_load事件中写
response.write(request.form("query"))
