首先，您无法从控制器调用javascript. Javascript在客户端运行，您的控制器在服务器上运行.
尽管您可以使视图代表服务器执行代码.

如果从验证的角度来讲，您可以在MVC3中进行客户端和服务器端的验证，也可以(应该)同时使用两者.如果您使用服务器端验证，则会发布页面，从而刷新页面.如果使用客户端一，则需要在客户端发送逻辑.以此方式实际上不可能验证凭据-这称为身份验证，而不是验证.

如果我正确理解了您的帖子，则您希望身份验证看起来像客户端验证.比您需要远程验证 [

First of all you can not call javascript from controller. Javascript runs on client side, your controller is running on the server.
Although you can make the view execute code on behalf of the server.

If speaking from validation in general, you can do client and server side validation in MVC3, or you can (should) use both. If you use server side validation, the page is posted, thus refreshed. If you use client side one, you need to send the logic on client side. Validating credentials is not really possible this way - and this is called authentication, not validation.

If I understand your post correctly, you want authentication to look and feel like client side validation. Than you need remote validation[^].
