Question

In Post Controller , URL is like this :

     http://127.0.0.1/post/5006/some-text-for-seo-friendly
     {contoller}/{id}/{seo}

     public ViewResult Index(){
     .....
     }

I used Ajax.BeginForm in index view and mapped it to AddComment action in the same controller.

  @using (Ajax.BeginForm("AddComment", "Post", new AjaxOptions()
                   {
                      HttpMethod = "GET",
                      InsertionMode = InsertionMode.InsertAfter,
                      UpdateTargetId = "comment-container"
           }))
            {
                <textarea cols="2" rows="2" name="comment" id="comment"></textarea>
                <input type="submit" value="Add Comment" />
            }

and in controller

    public PartialViewResult AddComment(string comment){
              // how can I get 5006 {id} here
    }

my question is how can I get the {id} [5006] in AddComment action.

注:难以使用<代码>查询。 UrlReferer, 并按/和选定表格阵列分别列出。

You need to supply the id to the BeginForm method using this overload which takes a routeValues parameter:

@using ( Ajax.BeginForm( "AddComment", "Post",
  new { id = 5006 },
  new AjaxOptions
  {
    ...

那么,你就应当能够把id作为你的行动方法的参数:

public PartialViewResult AddComment( int id, string comment )
{
  ...

MVC将使用AddComment,其人口价值为:
