Ajax.BeginForm 让我抓狂

Question

ASP.NET MVC3

我有一个最初在 div 内呈现的部分视图。以下是部分代码：

@model Venue.Models.Validation.CustomerRequestModel

<script src="@Url.Content("~/Scripts/jquery-1.4.4.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>

<script type="text/javascript" src="/Scripts/MicrosoftAjax.js"></script>
<script type="text/javascript" src="/Scripts/MicrosoftMvcAjax.js"></script>
<script type="text/javascript" src="/Scripts/MicrosoftMvcValidation.js"></script>

@{ Html.RenderPartial("Message"); }
@Html.ValidationSummary()

@using (Ajax.BeginForm(
            "Customer",
            "Service",
            null,
            new AjaxOptions()
            {
                HttpMethod = "post",
                InsertionMode = InsertionMode.Replace,
                LoadingElementDuration = 100,
                LoadingElementId = "loading-customer",
                OnBegin = "hideSubmitButton",
                OnSuccess = "hideForm",
                OnComplete = "showSubmitButton",
                OnFailure = "showErrorMessage",
                UpdateTargetId = "formclientes",
            },
            new
            {
                id = "customer-form"
            }))
{
    // Fields are all type="text" although some are numbers.
    <input type="text" name="Address" class="clientes_form" />
}

操作：

[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Customer(CustomerRequestModel customer)
{
  // ...
}

在立即窗口中，这就是我得到的：

this.Request.IsAjaxRequest()
false

为什么？！

如果您的 web.config 文件中有 jquery.unobtrusive-ajax.js，则应包含 jquery.unobtrusive-ajax.js

<add key="UnobtrusiveJavaScriptEnabled" value="true"/>

，该文件由 MVC3 RC2 默认启用。
并且还要删除最后 3 个（MicrosoftAjax、MicrosoftMvcAjax 和 MicrosoftMvcValidation）脚本引用，因为在使用非侵入式版本时不需要它们。
