MVC3页面 - 的IsPostBack一样的功能 [英] MVC3 Page - IsPostback like functionality

问题描述

我把从_Layout.cshtml观点相同的控制器多次。因此，在此控制器，我怎么能在运行时发现如果它仍然被渲染，或者一个全新的页面请求正在取得相同的网页？

I call the same controller many times from _Layout.cshtml view. So in this controller, how can I discover at runtime if it's still same page that is rendering or if a brand new page request is being made?

在asp.net可以使用的IsPostBack摸不着头脑。你怎么能判断一个全新的请求一个页面中MVC3内容？

In asp.net you can use ispostback to figure this out. How can you tell if a brand new request is being made for a page in MVC3?

感谢

推荐答案

有没有这样的想起MVC。你已经可以处理信息操作，获取或两者兼而有之。您可以过滤了每个动作可以用手柄 [HttpPost] 和 [HTTPGET] 属性。

There's no such think on MVC. You've actions that can handle POSTs, GETs or both. You can filter what each action can handle using [HttpPost] and [HttpGet] attributes.

在MVC中，你可以得到的IsPostBack 最接近的是这样的你的行动中：

On MVC, the closest you can get to IsPostBack is something like this within your action:

public ActionResult Index() 
{
    if (Request.HttpMethod == "POST") 
    {
        // Do something
    }

    return View();
}

因此​​，

[HttpPost]
public ActionResult Create(CreateModel model) 
{
    if (Request.HttpMethod == "POST") // <-- always true
    {
        // Do something
    }

    return RedirectToAction("Index");
}
