Question

我在/Shared/MainMenu.cshtml中有一个简单的菜单：

  <ul class="nav navbar-nav">
    <li class="active">@Html.ActionLink("Home", "Index", "Home")</li>
    <li>@Html.ActionLink("Features", "Index", "Features", "active")</li>
    <li>@Html.ActionLink("Faq", "Index", "Faq")</li>
    <li>@Html.ActionLink("Help", "Index", "Help")</li>
  </ul>

我想指出当前页面，但在Index.cshtml中设置一个值，并将相关

元素的类设置为＆＃34; active＆＃34;，就像＆＃34;首页＆＃34;菜单项有，上面。

设置相关

的类而不设置其他类的最简单方法是什么？

Answer 1

也许？

@{
    String controller = HttpContext.Current.Request.RequestContext.RouteData.Values["controller"].ToString();
}

<ul class="nav navbar-nav">
    <li class="@(controller == "Home" ? "active": "")">@Html.ActionLink("Home", "Index", "Home")</li>
    <li class="@(controller == "Features" ? "active": "")">@Html.ActionLink("Features", "Index", "Features", "active")</li>
    <li class="@(controller == "Faq" ? "active": "")">@Html.ActionLink("Faq", "Index", "Faq")</li>
    <li class="@(controller == "Help" ? "active": "")">@Html.ActionLink("Help", "Index", "Help")</li>
  </ul>

使用ASP.NET MVC条件设置li元素类
