这几天我一直在为此苦苦挣扎。我有一个表单，它是通过 Ajax 加载的部分视图，但它没有通过 Ajax 提交，即使它使用 Ajax.BeginForm()。
控制器：
<HttpGet()> _
Public Function PersonalDetailsEdit(PersonalInfo As DetailsViewModel.PersonalDetails) As PartialViewResult
Return PartialView(PersonalInfo)
End Function
<HttpPost()> _
<AjaxOnly()> _
Public Function PersonalDetailsEdit(formcollection As FormCollection, model As DetailsViewModel.PersonalDetails) As PartialViewResult
Return PartialView("PersonalDetails", model)
End Function
看法：
@ModelType ASK.Everest.ViewModels.DetailsViewModel.PersonalDetails
@Using Ajax.BeginForm("PersonalDetailsUpdate", "Details", New AjaxOptions() With {
.InsertionMode=InsertionMode.Replace,
.UpdateTargetId = "PersonalDetailsSection",
.OnFailure = "alert('fail');"}, New With {.id="PersonalDetailsForm"})
@Html.ValidationSummary(True)
@<fieldset id="PersonalDetailsUpdate">
<table class="table table-striped ">
<tr>
<th class="display-label">
<input type="hidden" value="@Html.NameFor(Function(model) model.Title)" />
@Html.DisplayNameFor(Function(model) model.Title)
</th>
<th class="display-label">
<input type="hidden" value="@Html.NameFor(Function(model) model.FirstName)" />
@Html.DisplayNameFor(Function(model) model.FirstName)
</th>
<th class="display-label">
<input type="hidden" value="Surname" />
@Html.DisplayNameFor(Function(model) model.Surname)
</th>
</tr>
<tr>
<td class="display-field">
@Html.DisplayFor(Function(model) model.Title)
</td>
<td class="display-field">
@Html.DisplayFor(Function(model) model.FirstName)
</td>
<td class="display-field">
@Html.DisplayFor(Function(model) model.Surname)
</td>
</tr>
<tr>

<th class="display-label">
@Html.DisplayNameFor(Function(model) model.Gender)

<th class="display-label">

@Html.DisplayNameFor(Function(model) model.DOB)
</th>
</tr>
<tr>

<td class="display-field">
@Html.DisplayFor(Function(model) model.Gender)

</table>
@*@Html.ActionLink("Back to List", "Index")*@
<p class="pull-right">
<input type="submit" value="Save" />
</p>
</fieldset>
End Using
我的捆绑包：
bundles.Add(New ScriptBundle("~/bundles/ask").Include(
"~/Scripts/jquery-1.7.*",
"~/Scripts/jquery-ui*",
"~/Scripts/jquery.validate*",
"~/Scripts/jquery.unobtrusive*",
"~/Content/bootstrap/js/bootstrap.js"))
_Layout.vbtml：
<!DOCTYPE html>
<html lang="eng">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width" />
<title>@ViewData("Title")</title>
@Styles.Render("~/Content/css")
@RenderSection("styles", required:=False)
@Scripts.Render("~/bundles/modernizr")
@Scripts.Render("~/bundles/ask")
@RenderSection("scripts", required:=False)
</head>
<body>
@RenderBody()
</body>
</html>
在经历了很多挫折之后放弃了，决定在客户端使用 MVVM 的 JQuery + Knockout 路线，如下所示：
<script type="text/javascript">
var data = @Html.Raw(Json.Encode(Model)) ;
var PersonalDetailsVM = ko.mapping.fromJS(data);
ko.applyBindings(PersonalDetailsVM, $('section#PersonalDetails')[0]);
</script>
现在我只是在为 JSON/MVC 日期转换而苦苦挣扎——我认为 MVC4 应该默认使用 JSON.NET？如果很麻烦，我会发布另一个问题。
