如何傳值在2個(gè)頁面之間要求不刷新父頁面，并且不能用Querystring傳值

通過Cookie，因?yàn)樗瓤梢栽诜?wù)器端對其進(jìn)行操作，也可在客戶端對其進(jìn)行操作但是缺點(diǎn)是不安全，而且有時(shí)客戶端會由于安全問題禁用Cookie！

例子：
以下是父頁的Html代碼
<%@ 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 頁[子頁]
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="child.aspx.vb" Inherits="zero.child"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<title>child</title>
<meta name="GENERATOR" content="Microsoft Visual Studio .NET 7.1">

<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");

</form>

</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?xì)w大哥介紹的方法
在父頁中加入一個(gè)非runat=server的form表單，用來提交隱藏控件的值到子頁
<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>
子頁的后臺代碼中 (.vb)
在Page_Load事件中寫
Response.Write(Request.Form("query"))
