SiteMap HtmlHelper ASP.NET MVC [英] SiteMap HtmlHelper ASP.NET MVC

问题描述

我已经重写了这篇文章，使其更加简单.这是我得到的代码(HtmlHelper):

I've rewritten this post to make it more simple. This is the code I've got (a HtmlHelper):

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Runtime.CompilerServices;
using System.Web.Mvc;
using System.Text;

using System.Web.Routing;

namespace Intranet.Helpers
{
  public static class MenuHelper
  {
    private static string GetBackLink(SiteMapNode parentNode)
    {
      return "<li class='li-back'><a href='" + parentNode.Url + "' title='" + parentNode.Title + "'></a></li>";
    }

    public static string Menu(this HtmlHelper helper)
    {
      var sb = new StringBuilder();
      SiteMapNodeCollection siteMapNodeCollection;
      sb.Append("<ul>");
      SiteMapNode currentNode = SiteMap.CurrentNode;

      if (!SiteMap.CurrentNode.Equals(SiteMap.RootNode))
      {
        if (!SiteMap.CurrentNode.HasChildNodes)
          sb.Append(GetBackLink(SiteMap.CurrentNode.ParentNode.ParentNode));
        else
          sb.Append(GetBackLink(SiteMap.CurrentNode.ParentNode));
      }

      if (!SiteMap.CurrentNode.HasChildNodes)
        siteMapNodeCollection = SiteMap.CurrentNode.ParentNode.ChildNodes;
      else
        siteMapNodeCollection = SiteMap.CurrentNode.ChildNodes;

      foreach (SiteMapNode node in siteMapNodeCollection)
      {
        if(node.Description.Equals("hidden")) continue;

        if (node.Url.Length == 0 && node.Description.Equals("separator"))
          sb.Append("<li class=\"li-separator\"></li>");
        else if (node.Url.Length == 0 && node.Description.Equals("heading"))
          sb.Append("<li class=\"li-heading\">" + node.Title + "</li>");
        else
        {
          if (node.HasChildNodes)
          {
            if (node.NextSibling != null)
              sb.Append("<li class=\"li-sub\"><a href=\"" + node.Url + "\">" + node.Title + "</a></li>");
            else
              sb.Append("<li class=\"li-sub last-child\"><a href=\"" + node.Url + "\">" + node.Title + "</a></li>");
          }
          else
          {
            if (node.NextSibling != null)
              sb.Append("<li><a href='" + node.Url + "'>" + node.Title + "</a></li>");
            else
              sb.Append("<li class='last-child'><a href='" + node.Url + "'>" + node.Title + "</a></li>");
          }
        }
      }

      sb.Append("</ul>");
      return sb.ToString();
    }
  }
}

是此的变体.我正在使用 MVC区域库，所以我可以无法看到 MvcSiteMap 可以与此一起工作，因为{controller}/{action}不再像以前那样工作了.

which is an altered version of this. I'm using MVC Areas Lib so I can't see how MvcSiteMap can work with this as it no longer works by {controller}/{action} like it did before.

说我有一个类似http://localhost/mycontroller/myaction的页面，它存在于SiteMap中，那么菜单将生成良好.但是说我http://localhost/mycontroller/myaction/50并指定一个参数，SiteMap生成器将不再起作用，因为该URL不存在. 教程不涵盖

Say I have a page like http://localhost/mycontroller/myaction and it exists in the SiteMap, then the menu will be generated fine. But say I do http://localhost/mycontroller/myaction/50 and specify a parameter, the SiteMap generator will no longer work because this URL does not exist. The tutorial doesn't cover MVC Areas Lib, so the solution to this problem doesn't work.
