ASP.NET MVC - 控制器参数不是从表单收集？ [英] ASP.NET MVC - Controller parameter not being gathered from form?

问题描述

我们现在有这个问题与控制器;控制器看起来是这样的：

We are having this problem with a controller right now; the controller looks like this:

public class AccountsController:Controller {
    public ActionResult List(int? page, int? pageSize, string keywords) {...}
}

我们正在通过jQuery发布此页：

We are posting to this page via jquery:

$.post("/myapp/Accounts/List",
       {"page":0,"pageSize":10,"keywords":"asdf"}, 
       updategrid,
       "json");
...
function updategrid(result) {...}

里面的动作：的Request.Form [关键词] ==ASDF，但关键字==在这里，我很茫然。为什么没有关键字有我们想要的价值呢？

Inside the action: Request.Form["keywords"] == "asdf", but keywords=="" and here I am at a loss. Why doesn't keywords have the value we want?

如何为你的控制器的存在
  实例化？我有这个问题，我
  发现它是我的
  SpringControllerFactory创建我
  控制器为singleton（因此
  总是使用从值
  第一次请求）。 - 马克·沃斯5月19日

How is your controller being instantiated? I had this problem and I found that it was my SpringControllerFactory creating my controllers as singletons (and hence was always using the values from the first request). – Mark Worth May 19 at 8:19

这就是它！我的控制器是
  注册为单到我
  温莎容器所以我
  WindsorControllerFactory返回
  单身。比尔 - 巴里5月19日

That's it! My controller was registered as a singleton into my Windsor container so my WindsorControllerFactory returned a singleton. – Bill Barry May 19 at 18:14
