前端的aspx页面写法

<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!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" >

<script language="JavaScript" type="text/javascript" src="Move.js"></script>

<head runat="server">
    <title>无标题页</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    <input name="Hidden_name" id="Hidden2" type="hidden" value="" />   
    <input id="btn" onclick="a()" type=button value="按下" />
                 
        <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" /></div>
    </form>
</body>
</html>

给Hidden2控件赋值

// JScript 文件

  function a()   
  {   
    document.getElementById("<%=Hidden2.ClientID>").value="456";
  }
