c# webform js文件获取客户端控件，后台cs获取前台客户端控件的值，c#和js的交互...-优快云博客

本文详细介绍了ASP.NET页面中使用C#语言编写的前端元素如按钮、隐藏域，以及事件处理函数的实现，包括JavaScript调用、属性绑定和服务器端响应。

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="" runat="server" />   
    <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";
  }

CS文件

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
	protected void Button1_Click(object sender, EventArgs e)
	{  
		Response.Write(Request.Form["Hidden_name"].ToString());
	}
}
