问题描述
假设我在这里有一个aspx代码：
Suppose I have an aspx code here:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="SearchCustomer.aspx.cs" Inherits="WebApplication1.eyeofheaven.SearchCustomer" %>
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>
<title>Search Customer</title>
</head>
<body>
<form id="form1" runat="server">
<div class="row">
<div class="twelve columns">
<!-- Header-->
<div class="container">
<nav role="navigation" class="navbar navbar-inverse navbar-fixed-top">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" data-target="#navbarCollapse" data-toggle="collapse" class="navbar-toggle">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<!-- Collection of nav links, forms, and other content for toggling -->
<div id="navbarCollapse" class="collapse navbar-collapse">
<ul class="nav navbar-nav">
<li><a href="EyeOfHeaven.aspx">Home</a></li>
<li class="dropdown">
<a data-toggle="dropdown" class="dropdown-toggle active" href="#">Search<b class="caret"></b></a>
<ul role="menu" class="dropdown-menu">
<li><a href="SearchCustomer.aspx">Search Form(Customer)</a></li>
<li><a href="SearchVehicle.aspx">Search Form(Vehicle)</a></li>
</ul>
</li>
</ul>
</div>
</nav>
</div>
</div>
</div>
<!-- Search form customer-->
<div id="searchcustomer" class="page-header">
<h3><span class="glyphicon glyphicon-th-large"></span>Search Customer</h3>
</div>
<div class="row">
<div class="col-md-4"><input type="text" size="20" class="form-control" placeholder="Customer ID"></div>
<div class="col-md-4">
<select class="form-control" id="Countries">
<option>Country</option>
</select>
</div>
<div class="col-md-4">
<select class="form-control" id="Regions">
<option>Regions</option>
</select>
</div>
</div>
<div class="row">
<div class="col-md-4">
<button type="button" onclick="Button1_Click()" id="searchinfo" class="btn btn-primary"><span class="glyphicon glyphicon-search"></span> Search Info</button>
</div>
</div>
<!-- Information Table-->
<div class="table-responsive">
<table id="MyTable" class="table table-bordered">
</table>
</div>
</form>
</body>
</html>
并且aspx.cs代码落后：
And aspx.cs code behind:
using MSSQLConnector;
using System;
using System.Collections.Generic;
using System.Data;
using System.Data.SqlClient;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace WebApplication1.eyeofheaven
{
public partial class SearchCustomer : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
Response.Write("<script>alert('Data Not Found.');</script>");
}
}
}
我想显示提醒（搜索信息按钮中的未找到数据。）。但是在控制台中出现错误未捕获的参考错误：未定义Button1_Click。我不知道是什么让代码出错。或者我的警报消息可能不是有效的c＃代码？我在这段代码中调用了函数Button1_Click：
I want to display an alert('Data not found.') in the search info button. But I get an error in the console "Uncaught Reference Error:Button1_Click is not defined". I have no idea what makes the code to have an error. Or maybe my alert message is not a valid c# code? I called the function Button1_Click in this code:
<button type="button" onclick="Button1_Click()" id="searchinfo" class="btn btn-primary"><span class="glyphicon glyphicon-search"></span> Search Info</button>
请帮助我是c＃语言的新手，我正在调整以下语法及其格式。
Please help I'm new to c# language and I'm adapting the following syntax and its format.
推荐答案
您的按钮未在服务器端定义。您需要使用 runat =server按钮并将 onclick 事件更改为 onserverclick 如下所示
Your button is not defined at server side. You need to use runat = "server" to button and change onclick event to onserverclick like below
<button type="button" id="searchinfo" runat="server" onserverclick="Button1_Click" class="btn btn-primary"><span class="glyphicon glyphicon-search"></span> Search Info</button>
而是使用 Asp.Net asp：按钮控件如下所示：
<asp:Button ID="searchinfo" runat="server" onclick="Button1_Click" cssClass="btn btn-primary" Text="Search Info" />
