Razor Pages操作来自输入按钮

我会给你举个简单的例子。创建razor页面并使用名称“Test”。测试。cshtml文件应包含以下内容:

@page
@model WebApplication1.Pages.TestModel
<form method="post">
    <fieldset>
        <input asp-for="username" placeholder="user name" />
        <span asp-validation-for="username" class="text-danger"></span>

        <br />

        <input asp-for="password" type="password" placeholder="password" />
        <span asp-validation-for="password" class="text-danger"></span>

        <br />

        <input type="submit" value="Submit" id="submitButton" />
    </fieldset>
</form>

测试。cshtml。cs应具有以下内容

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.RazorPages;

namespace WebApplication1.Pages
{
    public class TestModel : PageModel
    {
        [BindProperty]
        public string username { get; set; }

        [BindProperty]
        public string password { get; set; }

        public void OnGet()
        {
            // you can initialize the values. for example I set the username
            username = "test";
        }

        public IActionResult OnPost()
        {
            // do something with username and password

            if (string.IsNullOrEmpty(password))
            {
                ModelState.AddModelError("password", "Password is a required field.");
                return Page();
            }

            // or you can redirect to another page
            return RedirectToPage("./Index");
        }
    }
}

请告诉我您是否需要对这个示例进行额外的解释。我希望这有帮助。
