因为我使用html按钮和文本框来登录，所以我必须在源代码中的javascript中执行后面的代码才能执行后面的代码。无论我使用正确的用户名和密码（Admin 和 123）登录并单击登录按钮，还是不输入任何内容并单击登录按钮，它总是将我重定向到 ResultDetails.aspx。这意味着登录失败。如果将我重定向到 Search.aspx，则登录将通过。怎么了？即使我将.Value更改为.Text，效果仍然相同

我的代码背后的代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Login : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
You are 不使用asp.net服务器控件访问类似的值
txtUserName.Value
相反，您正在使用Javascript on HTML控制。所以，你的语法应该是这样的：
if (document.getElementById("txtUserName").value == "Admin" && document.getElementById("txtPassword").value == "123")
