problem sending value from jquery modal popup to parent

问题

Can you tell me how to send label1.text on this page to product.aspx and update label1.text ???

product.aspx

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
     <title></title>
     <link href="styles/modal-window.css" type="text/css" rel="stylesheet" />
     <script type="text/javascript" language="javascript" src="scripts/jquery-1.3.2.min.js"></script>
     <script type="text/javascript" language="javascript" src="scripts/modal-window.min.js"></script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:Label ID="Label1" runat="server" Text="0"></asp:Label>
        <br />
        <asp:Button ID="Button1" runat="server" onclick="Button1_Click" 
            Text="icrement" />
        <a href="viewcart.aspx?fn=<%= Label1.Text %>" onclick="$(this).modal({width:833, height:453}).open(); return false;">show popup</a>

    {
        if (!Page.IsPostBack)
        {
            Label1.Text = Request["fn"];
        }
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Label1.Text = (int.Parse(Label1.Text) - 1).ToString();
    }
}

You can add an asp:HiddenField control to the page, set its value through javascript and it will be posted back to your codebehind.
