Question

我有部分联系视图。目前索引视图显示联系人详细信息的此部分视图。部分视图内部有一个保存按钮，用于保存编辑的数据。保存编辑后的数据时会对年龄进行验证。这很好。

每当用户编辑年龄并保存时，我需要在主视图上显示相应的占星预测。我们如何实现它？

enter image description here

public class ContactEntity
{
    public int ContactID { get; set; }
    public string ContactName { get; set; }

    [Range(18, 50, ErrorMessage = "Must be between 18 and 50")]
    public int ContactAge { get; set; }
}

public class AgeHoroscope
{
    public int Age { get; set; }
    public string HoroscopePrediction { get; set; }
}

// Home Controller

namespace MYContactEditPartialViewTEST.Controllers
{
public class HomeController : Controller
{

    List<AgeHoroscope> horoList = new List<AgeHoroscope>()
    {
        new AgeHoroscope{Age=16,HoroscopePrediction="You are confused"},
        new AgeHoroscope{Age=26,HoroscopePrediction="You are very brilliant"},
        new AgeHoroscope{Age=27,HoroscopePrediction="You are practical"}
    };

    public ActionResult Index()
    {
        AgeHoroscope selectedHoro = horoList[1];
        return View(selectedHoro);
    }

  }
 }

//联系控制器

namespace MYContactEditPartialViewTEST.Controllers
{
public class ContactController : Controller
{

    public PartialViewResult MyContactDetailEdit()
    {
        Thread.Sleep(500);
        return PartialView(GetContact());
    }


    [HttpPost]
    public PartialViewResult MyContactDetailEdit(string conatcclick)
    {
        //Save to database
        Thread.Sleep(500);
        return PartialView(GetContact());
    }


    private ContactEntity GetContact()
    {
        ContactEntity contactEntity = new ContactEntity();
        contactEntity.ContactID = 1;
        contactEntity.ContactName = "Lijo";
        contactEntity.ContactAge = 26;
        return contactEntity;
    }

 }
}

// Index.cshtml

@model  MYContactEditPartialViewTEST.AgeHoroscope
@{
 ViewBag.Title = "Index";
}

<script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript">       </script>



<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>

<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

<div>
<a>Your age is <b>@Html.DisplayFor(x => x.Age) </b>and the prediction is <b>" @Html.DisplayFor(x => x.HoroscopePrediction)
    " </b></a>
<br />
 </div>
<div style="border: 3px solid Teal">
@Html.Action("MyContactDetailEdit", "contact")

// MyContactDetailEdit.cshtml

@model  MYContactEditPartialViewTEST.ContactEntity


@using (Html.BeginForm())

@Html.ValidationSummary(true)

<h3>MyContactDetailEdit PARTIAL</h3>

@Html.ValidationMessageFor(model => model.ContactAge)

 <input type="submit" id="saveButton" value="Save" />

我想使用jQuery来执行ajax发布，然后直接更改父视图客户端

Answer 2

您需要创建一个新的ViewModel才能执行此操作。这个ViewModel（IndexViewModel.cs）看起来像这样（我猜这个）：

public class IndexViewModel
{
    public int ContactID { get; set; }
    public string ContactName { get; set; }
    public int ContactAge { get; set; }
    public string HoroscopePrediction { get; set; }
}

然后在控制器索引操作（和视图）中使用它：

@model  MYContactEditPartialViewTEST.IndexViewModel

这个想法是你在ContactEntity和AgeHoroscope（或通过Linq等）之间的联接中填充HoroscopePrediction，从而将索引中的每一行显示为一个完整的对象（显示联系人和占星术）。

Answer 3

当数据发布到“HomeController”和“Index”操作时，在View中更改年龄时会反映出更改。

尝试按如下方式修改家庭控制器，然后它将按预期工作。

1）我们可以提供年龄和预测字典，而不是拥有AgeHoroscope列表。

2）为HttpGet和HttpPost创建两个索引操作，如下所示。

public class HomeController : Controller
{

    Dictionary<int, string> AgePred = new Dictionary<int, string>()
    {
    {16,"You are confused"},
    {26,"You are very brilliant"},
    {27,"You are practical"}
    };

    [HttpGet]
    public ActionResult Index()
    {
        AgeHoroscope selectedHoro = new AgeHoroscope() { Age = 26 };
        selectedHoro.HoroscopePrediction = AgePred[selectedHoro.Age];
        return View(selectedHoro);
    }
    [HttpPost]
    public ActionResult Index(AgeHoroscope model,ContactEntity entity)
    {
        model.Age = entity.ContactAge;
        model.HoroscopePrediction = AgePred[entity.ContactAge];
        return View(model);
    }

}
