表格後傳遞空模型 - .NET MVC 4

Question

我使用this post as reference

我試圖讓我傳遞給視圖點擊輸入時回發到控制器的HttpPost方法的模型。 但是，該模型（在本例中僅爲List）在回發時爲空。

我已經包含了我的代碼以供參考。這只是一個測試隨機東西的項目，所以我爲蹩腳的代碼道歉。

我有以下視圖代碼：（顯示爲completness整個代碼）

@{ 
    ViewBag.Title = "Home Page"; 
} 
@using TestApp.MyObjects 
@model List<Contact> 
@Ajax.ActionLink("Show About", "About", new { id = "1" }, new AjaxOptions { InsertionMode = InsertionMode.Replace, UpdateTargetId = "contentDiv" }) 
@Ajax.ActionLink("Show Contact", "Contact", new AjaxOptions { InsertionMode = InsertionMode.Replace, UpdateTargetId = "contentDiv" }) 
<div id="contentDiv"></div> 
@using (Html.BeginForm()) 
{ 

    <table> 
     @foreach (Contact c in Model) 
     { 
      <tr> 
       <td> 
        <button aboutnum0 = "@c.someValues[0]" aboutnum1 = "@c.someValues[1]" aboutnum2 = "@c.someValues[2]" class="nameButton">@c.name</button> 
       </td> 
      </tr> 
     } 
    </table> 
    <input value="@Model[0].name" /> 
    <input value="@Model[0].name" /> 
    <div id ="aboutContentDiv"></div> 
    <input type="submit" /> 
    @ViewBag.myCoolValue 
} 
<script type="text/javascript"> 
    $("button").click(function() { 
     $("#aboutContentDiv").empty(); 
     $("#aboutContentDiv").append($("<div></div>").load("Home/About/" + $(this).attr("aboutnum0"))); 
     $("#aboutContentDiv").append($("<div></div>").load("Home/About/" + $(this).attr("aboutnum1"))); 
     $("#aboutContentDiv").append($("<div></div>").load("Home/About/" + $(this).attr("aboutnum2"))); 
    }); 

</script> 

以下是我的Comtroller代碼：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Web; 
using System.Web.Mvc; 
using TestApp.MyObjects; 

namespace TestApp.Controllers 
{ 
    public class HomeController : Controller 
    { 
     public ActionResult Index() 
     { 
      ViewBag.Message = "Modify this template to jump-start your ASP.NET MVC application."; 
      Contact c = new Contact(); 
      c.name = "Some Name"; 
      c.someValues = new List<string>(); 
      c.someValues.Add("1"); 
      c.someValues.Add("2"); 
      c.someValues.Add("3"); 
      Contact c1 = new Contact(); 
      c1.name = "Some Name1"; 
      c1.someValues = new List<string>(); 
      c1.someValues.Add("4"); 
      c1.someValues.Add("5"); 
      c1.someValues.Add("6"); 
      Contact c2 = new Contact(); 
      c2.name = "Some Name2"; 
      c2.someValues = new List<string>(); 
      c2.someValues.Add("7"); 
      c2.someValues.Add("8"); 
      c2.someValues.Add("9"); 
      List<Contact> clist = new List<Contact>(); 
      clist.Add(c); 
      clist.Add(c1); 
      clist.Add(c2); 
      Session["myCoolValue"] = "Cool1"; 
      TempData["myCoolValue"] = "Cool2"; 
      return View(clist); 
     } 
     [HttpPost] 
     public ActionResult Index(List<Contact> contacts) 
     { 
      string name = contacts[0].name; 
      return View("Index",contacts); 
     } 
     public PartialViewResult About(string id = "") 
     { 
      ViewBag.Message = "Your app description page."; 
      About a = new About(); 
      a.someValue = id + " _ modified by contoller"; 
      ViewBag.myCoolValue = "Cool"; 
      return PartialView("About",a); 
     } 

     public PartialViewResult Contact() 
     { 
      ViewBag.Message = "Your contact page."; 

      return PartialView("Contact"); 
     } 
    } 
}

根據您的回覆我的意見，你需要這樣的事情：

// you can use foreach and have a counter variable or this 
    for (int i = 0; i < Model.Count; i++) 
    { 
    // you do not want to use a partial view so let's do it this way 
    // put this in an appropriate place in your code 
    // like inside a tr or div, it's up to you 
    @Html.TextboxFor(m => m[i].name) 

    }
