有Index视图如下:
视图代码如下:
- <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>
- <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
- 主页
- </asp:Content>
- <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">
- <h2><%= Html.Encode(ViewData["Message"]) %></h2>
- <br />
- <br />
- <% using(Html.BeginForm("HandleForm", "Home")) %>
- <% { %>
- Enter your name: <%= Html.TextBox("name") %>
- <br /><br />
- Select your favorite color:<br />
- <%= Html.RadioButton("favColor", "Blue", true) %> Blue <br />
- <%= Html.RadioButton("favColor", "Purple", false)%> Purple <br />
- <%= Html.RadioButton("favColor", "Red", false)%> Red <br />
- <%= Html.RadioButton("favColor", "Orange", false)%> Orange <br />
- <%= Html.RadioButton("favColor", "Yellow", false)%> Yellow <br />
- <%= Html.RadioButton("favColor", "Brown", false)%> Brown <br />
- <%= Html.RadioButton("favColor", "Green", false)%> Green
- <br /><br />
- <%= Html.CheckBox("bookType") %> I read more fiction than non-fiction.<br />
- <br /><br />
- My favorite pet: <%= Html.DropDownList("pets") %>
- <br /><br />
- <input type="submit" value="Submit" />
- <% } %>
- </asp:Content>
如图填写表单数据:
分别使用不同的表单处理方法,对提交的表单数据在视图FormResults呈现。
提交表单对应的HomeController,包含以不同方法获取表单数据的代码,如下:
- using System;
- using System.Collections.Generic;
- using System.Linq;
- using System.Web;
- using System.Web.Mvc;
- namespace HtmlHelper.Controllers
- {
- [HandleError]
- public class HomeController : Controller
- {
- public ActionResult Index()
- {
- ViewData["Message"] = "欢迎使用 ASP.NET MVC!";
- //手动构造页面中下拉框的宠物数据
- List<string> petList = new List<string>();
- petList.Add("Dog");
- petList.Add("Cat");
- petList.Add("Hamster");
- petList.Add("Parrot");
- petList.Add("Gold fish");
- petList.Add("Mountain lion");
- petList.Add("Elephant");
- ViewData["Pets"] = new SelectList(petList);
- return View();
- }
- public ActionResult About()
- {
- return View();
- }
- /// <summary>
- /// 处理表单提交数据,方法1:使用传统的Request请求取值
- /// </summary>
- /// <returns></returns>
- public ActionResult HandleForm()
- {
- ViewData["name"] = Request["name"];
- ViewData["favColor"] = Request["favColor"];
- ViewData["bookType"] = Request["bookType"];
- ViewData["pet"] = Request["pets"];
- return View("FormResults");
- }
- /// <summary>
- /// 处理表单提交数据,方法2:Action参数名与表单元素name值一一对应
- /// </summary>
- /// <param name="name"></param>
- /// <param name="favColor"></param>
- /// <param name="bookType"></param>
- /// <param name="pets"></param>
- /// <returns></returns>
- //public ActionResult HandleForm(string name, string favColor, Boolean bookType, string pets)
- //{
- // ViewData["name"] = name;
- // ViewData["favColor"] = favColor;
- // ViewData["bookType"] = bookType;
- // ViewData["pet"] = pets;
- // return View("FormResults");
- //}
- /// <summary>
- /// 处理表单提交数据,方法3:从MVC封装的FormCollection容器中读取
- /// </summary>
- /// <param name="form"></param>
- /// <returns></returns>
- //public ActionResult HandleForm(FormCollection form)
- //{
- // ViewData["name"] = form["name"];
- // ViewData["favColor"] = form["favColor"];
- // ViewData["bookType"] = form["bookType"];
- // ViewData["pet"] = form["pets"];
- // return View("FormResults");
- //}
- /// <summary>
- /// 处理表单提交数据,方法4:使用实体作为Action参数传入,前提是提交的表单元素名称与实体属性名称一一对应
- /// </summary>
- /// <param name="request"></param>
- /// <returns></returns>
- //[HttpPost]
- //public ActionResult HandleForm(InforModel infor)
- //{
- // ViewData["name"] = infor.name;
- // ViewData["favColor"] = infor.favColor;
- // ViewData["bookType"] = infor.bookType;
- // ViewData["pet"] = infor.pets;
- // return View("FormResults");
- //}
- }
- }
在FormResults视图显示ViewData的数据,如图所示:
