Asp.net mvc 4 httppost未能在模式引导中显示

我使用的是引导模式，我使用以下链接构建了模式：

一切正常，除了我调用[httppost]时，操作中出现了一些错误，如发布的电子邮件错误或不存在，然后我想在模式上显示错误。 而不是在模式上显示错误，而是在新页面中显示错误

_Layout.cshtml

<div class="modal fade" id="log-in" tabindex="-1" aria-hidden="true" style="display: none;">
    @Html.Action("Login","User")
</div>

如果您希望登录表单处于模式，则需要使用ajax发布表单，这样您就可以停留在同一页面上，并可以使用返回的错误消息或表单的部分视图更新DOM。我尝试过，但可能是我设置了错误可能是UpdatetargetidI尝试过了？试过什么？我们猜不出你做错了什么。@StephenMuecke：更新了ajax代码。。请检查并让我知道……谢谢

返回PartialView（“u Login”，model）

将您重定向到一个新页面，这意味着您没有在主视图（或布局）中包含

jquery.unobtrusive ajax.js

脚本
