[asp.net-mvc] ASP.NET MVC 부분보기 : 입력 이름 접두사

MVC2를 사용하면이를 달성 할 수 있습니다.

다음은 강력한 형식의보기입니다.

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MvcLearner.Models.Person>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    Create
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    <h2>Create</h2>

    <% using (Html.BeginForm()) { %>
        <%= Html.LabelFor(person => person.Name) %><br />
        <%= Html.EditorFor(person => person.Name) %><br />
        <%= Html.LabelFor(person => person.Age) %><br />
        <%= Html.EditorFor(person => person.Age) %><br />
        <% foreach (String FavoriteFoods in Model.FavoriteFoods) { %>
            <%= Html.LabelFor(food => FavoriteFoods) %><br />
            <%= Html.EditorFor(food => FavoriteFoods)%><br />
        <% } %>
        <%= Html.EditorFor(person => person.Birthday, "TwoPart") %>
        <input type="submit" value="Submit" />
    <% } %>

</asp:Content>

다음은 하위 클래스에 대한 강력한 형식의보기입니다 (EditorTemplates라는보기 디렉터리의 하위 폴더에 저장되어야 함).

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MvcLearner.Models.TwoPart>" %>

<%= Html.LabelFor(birthday => birthday.Day) %><br />
<%= Html.EditorFor(birthday => birthday.Day) %><br />

<%= Html.LabelFor(birthday => birthday.Month) %><br />
<%= Html.EditorFor(birthday => birthday.Month) %><br />

컨트롤러는 다음과 같습니다.

public class PersonController : Controller
{
    //
    // GET: /Person/
    [AcceptVerbs(HttpVerbs.Get)]
    public ActionResult Index()
    {
        return View();
    }

    [AcceptVerbs(HttpVerbs.Get)]
    public ActionResult Create()
    {
        Person person = new Person();
        person.FavoriteFoods.Add("Sushi");
        return View(person);
    }

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Create(Person person)
    {
        return View(person);
    }
}

다음은 사용자 정의 클래스입니다.

public class Person
{
    public String Name { get; set; }
    public Int32 Age { get; set; }
    public List<String> FavoriteFoods { get; set; }
    public TwoPart Birthday { get; set; }

    public Person()
    {
        this.FavoriteFoods = new List<String>();
        this.Birthday = new TwoPart();
    }
}

public class TwoPart
{
    public Int32 Day { get; set; }
    public Int32 Month { get; set; }
}

출력 소스 :

<form action="/Person/Create" method="post"><label for="Name">Name</label><br />
    <input class="text-box single-line" id="Name" name="Name" type="text" value="" /><br />
    <label for="Age">Age</label><br />
    <input class="text-box single-line" id="Age" name="Age" type="text" value="0" /><br />
    <label for="FavoriteFoods">FavoriteFoods</label><br />
    <input class="text-box single-line" id="FavoriteFoods" name="FavoriteFoods" type="text" value="Sushi" /><br />
    <label for="Birthday_Day">Day</label><br />
    <input class="text-box single-line" id="Birthday_Day" name="Birthday.Day" type="text" value="0" /><br />

    <label for="Birthday_Month">Month</label><br />
    <input class="text-box single-line" id="Birthday_Month" name="Birthday.Month" type="text" value="0" /><br />
    <input type="submit" value="Submit" />
</form>

이제 완료되었습니다. Create Post 컨트롤러 작업에서 중단 점을 설정하여 확인합니다. 그러나 작동하지 않기 때문에 목록과 함께 사용하지 마십시오. 이에 대한 자세한 내용은 IEnumerable과 함께 EditorTemplates 사용에 대한 내 질문을 참조하십시오.
