我有一个控制器,它返回一个带有模型的部分视图。
包含部分视图的视图有一个按钮,当单击按钮时,将调用控制器的一个功能,并返回相同的部分视图,并更新模型。加载新模型没有任何问题,但页面没有重新加载,视图与onclik之前的视图相同。
部分视图的代码
<div class="well">
@if (publication.Coments != null) {
foreach (var comments in publication.Coments) {
<div class="row">
<div class="col-md-12">
<a href="../../Client/ProfilePerNick?nick=@comments.Nick">@comments.Nick</a>
<span class="pull-right">@comments.DateComment.ToShortDateString()</span>
<p>@comments.Message</p>
</div>
</div>
}
}
</div>
控制器的方法使用下一个代码返回局部视图:
ViewData["publication"] = publication;
return PartialView("details_comment");
我在视图中调用局部视图:
@Html.Partial("../Home/ListPublication")
我调试了页面,模型重新加载好了,但部分视图没有重新加载。

我在评论中提到我遇到了同样的问题,但今天晚些时候我在MSDN上发现,如果您返回相同的模型并在{{1}之后查看类型,这是预期的行为}。对于我的场景,我必须在更改返回视图模型上的任何值之前使用POST
。为了更好地解释一下,我会尽量描述我的情况,尽可能地记住尝试语境化:
查看模型
ModelState.Clear()
模板
// ~/Models/SomeFeatureModels.cs
public class SomeViewModel {
public int Id {get;set;}
public string SomeField{get;set;}
public string SomeOtherField{get;set;}
public DateTime CreatedOn{get;set;}
}
public class SomeOtherViewModel {
public int Id {get;set;}
public string SomeField{get;set;}
public string SomeOtherField{get;set;}
public DateTime CreatedOn{get;set;}
}
public class IndexViewModel {
public string FeatureTitle{get;set;}
}
<强>控制器强>
<!-- ~/Views/Some/SomeInfo.cshtml -->
@model.App.Models.SomeInfoViewModel
@using(Html.BeginForm("AddSomeInfo", "Some", FormMethod.Post, new { @id="frmAddSomeInfo" }) {
<div id="some-info">
@Html.DisplayFor(m=>m.SomeField)
@Html.EditorFor(m=>m.SomeField)
@Html.ValidatorFor...
<input type="submit">Go</input>
</div>
}
<!-- ~/Views/Some/SomeInfo.cshtml -->
@model.App.Models.SomeOtherInfoViewModel
@using(Html.BeginForm("AddSomeOtherInfo", "Some", FormMethod.Post, new { @id="frmAddSomeOtherInfo" }) {
<div id="some-other-info">
@Html.DisplayFor(m=>m.SomeField)
@Html.EditorFor(m=>m.SomeField)
@Html.ValidatorFor...
<input type="submit">Go</input>
</div>
}
<!-- ~/Views/Some/Index.cshtml -->
@model App.Models.IndexViewModel
@{
layout: "someLayout.cshtml"
}
<h2>Model.FeatureTitle</h2>
@{ RenderAction("SomeInfo") }
@{ RenderAction("SomeOtherInfo") }
@section scripts {
//bundle must include:
// jquery, jquery.unobtrusive.ajax, jquery.validate, jquery.validate.unobtrusive
<script>
$(function() {
$('#frmAddSomeInfo').submit(function(e) {
e.preventDefault();
var form = $(this);
if (form.valid()) {
$.ajax({
url: form.action,
type: form.method,
data: form.serialize()
}).done(function(payload) {
$('#some-info').html(payload);
}).fail(function(jqXHR, error, errorThrown) {
// handle
});
}
});
$('#frmAddSomeOtherInfo').submit(function(e) {
e.preventDefault();
var form = $(this);
if (form.valid()) {
$.ajax({
url: form.action,
type: form.method,
data: form.serialize()
}).done(function(payload) {
$('#some-other-info').html(payload);
}).fail(function(jqXHR, error, errorThrown) {
// handle
});
}
});
});
</script>
}
这是我必须使用// ~/Controllers/SomeController.cs
public class SomeController: Controller {
// This would be the landing view of a given controller
public ActionResult Index() {
// for this view model I have basically typed the things that
// are a concern of Index, like page title and other things
// but nothing related to the view models that I will be
// updating or inserting
var viewModel = somePrivateMethodToBuildMyViewModel();
return View(viewModel);
}
public PartialViewResult SomeInfo() {
// this is technically a fresh instance with normalized
// or localized default data that I will be sending
// when the index requests this partial view
var someViewModel = somePrivateMethodToBuildSomeViewModel();
return PartialView(someViewModel);
}
[HttpPost]
public PartialViewResult AddSomeInfo(SomeViewModel viewModel) {
// this is where I am checking if my view model is alright
// and then the "issue" will occur
if (!ModelState.IsValid) {
// ... handle
} else {
// I was doing "normal stuff" like
// translating view model to an entity (let's call it model)
// committing changes with some ORM and get and id and timestamp back
// and naturally assign these values to the view model
viewModel.Id = model.id;
viewModel.createdOn = model.created_on;
}
// then return the same view and same model **types** of the request
return PartialView("SomeInfo", viewModel);
}
}
的部分。我已将ModelState.Clear()
操作更改为:
POST
对不起,这有点太多了,但我只是想表明我是如何让它在我的场景中运作的。

您需要使用局部视图传递模型的对象以查看值,因为您的模型将与帮助程序绑定以创建视图
return PartialView("details_comment",publication);

而不是相对网址:
Try: @Html.Partial(@"~/Views/Home/ListPublication.cshtml") or use
@{Html.RenderPartial("ListPublication");}
我注意到的另一件事是你使用旧的ViewData
。我并不是说你根本不应该使用它,但更好的方法是使用强类型的ViewModel。视图模型是一个类,它具有视图呈现所需的属性和逻辑。所以你可以上课:
public class PublicationVM{public Publication publication {get; set;} }
并且如果视图需要,可以具有其他必要的属性。 SO有很多关于使用View Model的信息。请检查What is ViewModel in MVC?
