從卡中移除Ajax方法不適用於音樂商店購物卡的MVC4教程

Question

我跟着MVC4 Music Store tutorial for making a shopping card。不幸的是，當我使用RemoveFromCard功能我得到以下信息：

The resource cannot be found. 
    Description: HTTP 404. The resource you are looking for (or one of its 
    dependencies) could have been removed, had its name changed, or is temporarily 
    unavailable. Please review the following URL and make sure that it is spelled 
    correctly. 

Requested URL: /ShoppingCart/RemoveFromCart/1 

我的查看頁面中使用的代碼如下：

<script src="/Scripts/jquery-1.8.2.min.js" type="text/javascript"></script> 

<script type="text/javascript"> 
    $(function() { 
     // Document.ready -> link up remove event handler 
     $(".RemoveLink").click(function() { 
      // Get the id from the link 
      var recordToDelete = $(this).attr("data-id"); 
      if (recordToDelete != '') { 
       // Perform the ajax post 
       $.post("/ShoppingCart/RemoveFromCart", { "id": recordToDelete }, 
       function (data) { 
        // Successful requests get here 
        // Update the page elements 
        if (data.ItemCount == 0) { 
         $('#row-' + data.DeleteId).fadeOut('slow'); 
        } 
        else { 
         $('#item-count-' + data.DeleteId).text(data.ItemCount); 
        } 

        $('#cart-total').text(data.CartTotal); 
        $('#update-message').text(data.Message); 
        $('#cart-status').text('Cart (' + data.CartCount + ')'); 
       }); 
      } 
     }); 
    }); 

</script> 

用下面的ActionLink：

<td> 
       <%: Ajax.ActionLink("Remove from cart", "RemoveFromCart", 
         new { id = item.RecordId }, 
         new AjaxOptions { OnSuccess = "handleUpdate" })%> 
      </td> 

此外，

我在ShoppingCard.cs中有此方法

public int RemoveFromCart(int id) //code 

爲什麼找不到這種方法？我會非常感謝一些幫助！

好吧，我解決了這個問題......我改變了ActionLink的到：

<a href="#" class="RemoveLink" data-id="<%:item.RecordId %>">Remove from cart</a> 

，現在它的工作。
