而且aspx.cs後臺代碼：

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>"); 
     } 
    } 
}

我要顯示一個警告（「數據找不到。'）在搜索信息按鈕中。但是我在控制檯出現錯誤「Uncaught Reference Error：Button1_Click is not defined」。我不知道是什麼讓代碼出現錯誤。或者，也許我的警報消息不是一個有效的C＃代碼？我在此代碼中調用了Button1_Click函數：

<button type="button" onclick="Button1_Click()" id="searchinfo" class="btn btn-primary"><span class="glyphicon glyphicon-search"></span> Search Info</button>

請大家幫忙我是新來的c＃語言，我正在修改以下語法和格式。

您的按鈕沒有在服務器端定義。您需要使用runat = "server"到按鈕並更改onclick事件onserverclick像下面

<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:Button control象下面這樣：

<asp:Button ID="searchinfo" runat="server" onclick="Button1_Click" cssClass="btn btn-primary" Text="Search Info" />

大家好，先生謝謝大家回答我的問題，肯定有用。因此，不建議使用此代碼：？ –

如果您使用的是asp.net，那麼最好使用asp.net控件。 –

@laurencekeithalbano你仍然可以使用'

你需要使它asp button這樣

<asp:Button onclick="Button1_Click" ID="searchinfo" cssClass="btn btn-primary" Text="Search Info" runat="Server">

@RahulNikate是錯字感謝。 – Mairaj

試試這個：

<asp:Button onclick="Button1_Click" ID="searchinfo" 
     cssClass="btn btn-primary" Text="Search Info" runat="Server">

即，將按鈕定義爲runat="Server"。只需添加runat屬性將告訴ASP.Net將該元素及其屬性和內容解析爲服務器控件。
