不知道Request对象的来源

So there is this method in my controller

所以在我的控制器中有这种方法

[HttpPost]
public ActionResult Summary(string id, Summary model)
{
  int projectID;
  if (Int32.TryParse(id, out projectID))
  {
   switch (Request["PageType"])
   {
      case "Results":
       model = new Summary(SummaryType.SCS, GetSCSData(projectID, Request["Names"], true), projectID, SCSView.ResultsPage);
       break;
      case "Recipients":
       model = new Summary(SummaryType.SCS, GetProjectData(projectID, Request["Names"]), projectID)
       {
          Names = Request["Names"],
          HTMLAttachment = ParseBool(Request["HTMLAttachment"])
        };
        break;                    
       default:
        model = new Summary();
         break;
        }
    }

And was wondering where the Request["Names"] came from. I understand that is the request object from my Http request call. But how was it constructed and sent? I know it has something to do with my view, which look like this

并且想知道Request [“Names”]的来源。我理解这是来自我的Http请求调用的请求对象。但它是如何构建和发送的?我知道它与我的观点有关,看起来像这样

 using (Html.BeginForm(Summary, "Mycontroller", FormMethod.Post, new { id = "gridForm" }))
  { 
    @(Html.Kendo().Grid(Model.scsGridList) ... kendo stuff
    <input id="gridPage" name="PageType" type="hidden" value="" />
    <input id="gridProjectID" name="ProjectID" type="hidden" value="@Model.ProjectID" />
    <input id="gridJobs" name="Jobs" type="hidden" value="" />
    <input id="gridHTMLAttach" name="HTMLAttachment" type="hidden" value="true" />
  <div style="width: 100%; padding-top:5px;">                           
    <a id="email" href="#"><span class="ui-icon ui-icon-mail-closed linkicon"></span>Email</a>                            
  </div>

In my javascript is this

在我的JavaScript中是这样的

$("#email").on("click", function (e) {
        SendTo("Recipients");
    });

function SendTo(pageType){
    var values = GetSelectedValues();
    if(values){
        $("#gridPage").val(pageType);
        $("#gridJobs").val(values);
        $("#gridForm").submit();
    } else {
        $("#gridMessage").html("Please select a job.");
    }
}

I am just confuse as to how the Request object came to be populated with data such as Request["HTMLAttachment"] and Request["Names"]. Does it know to map to the model? Am I making sense?

我只是混淆了Request对象如何填充Request [“HTMLAttachment”]和Request [“Names”]等数据。是否知道要映射到模型?我有道理吗?

Because you placed all your inputs inside form, then when you submit it browser will populate key-value pairs, where keys are the names of inpurs inside form. It will do for every input element in form, even invisible. And as it stated here: http://msdn.microsoft.com/en-us/library/ms524948(v=vs.90).aspx

因为您将所有输入放在表单中,所以当您提交它时,浏览器将填充键值对,其中键是表单内的inpurs的名称。它将对表单中的每个输入元素执行操作,甚至是不可见的。正如它在此处所述:http://msdn.microsoft.com/en-us/library/ms524948(v = vs。90).aspx

The Request object retrieves the values that the client browser passed to the server during an HTTP request.

Request对象检索客户端浏览器在HTTP请求期间传递给服务器的值。
