我在 VS 2012 中使用标准的 MVC4 模板。它带有一个 _layout.cshtml 文件,如下所示:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>@ViewBag.Title - iLoveSport</title>
<link href="~/favicon.ico" rel="shortcut icon" type="image/x-icon" />
<meta name="viewport" content="width=device-width" />
@Styles.Render("~/Content/css")
@Styles.Render("~/Content/kendo")
@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/kendo")
@Scripts.Render("~/bundles/modernizr")
</head>
<body>
<header>
<div class="content-wrapper">
<div class="float-left">
<img src="~/Images/logo.png" alt="ILoveSport Logo" />
</div>
<div class="float-right">
<section id="login">
</section>
<nav>
<ul id="menu">
<li>@Html.ActionLink("Home", "Index", "Home")</li>
<li>@Html.ActionLink("AFL", "Index", "AFL")</li>
<li>@Html.ActionLink("NRL", "Index", "NRL")</li>
<li>@Html.ActionLink("State of Origin", "Index", "State of Origin")</li>
<li>@Html.ActionLink("Cricket", "Index", "Cricket")</li>
<li>@Html.ActionLink("Golf", "Index", "Gof")</li>
<li>@Html.ActionLink("Motorsport", "index", "Motorsport")</li>
<li>@Html.ActionLink("About", "About", "Home")</li>
<li>@Html.ActionLink("Contact", "Contact", "Home")</li>
</ul>
</nav>
</div>
</div>
</header>
<div id="body">
@RenderSection("featured", required: false)
<section class="content-wrapper main-content clear-fix">
@RenderBody()
</section>
</div>
<footer>
<div class="content-wrapper">
<div class="float-left">
</div>
</div>
</footer>
@Scripts.Render("~/bundles/jquery")
@RenderSection("scripts", required: false)
</body>
</html>
_viewstart.cshtml 包含以下内容:
@{
Layout = "~/Views/Shared/_Layout.cshtml";
}
必须修改什么以使我的 _layout.cshtml 页面中的导航仅在主页上被抑制?主页需要有一个按钮,然后该按钮将触发当前是我的主页的内页。我是否创建一个新的布局文件来抑制菜单并更改 viewstart 来加载它?或者,这可以通过其他方式完成吗?
感谢您的帮助和指导。
更新:
我的家庭控制器现在如下:
[ChildActionOnly]
public ActionResult NavigationMenu()
{
string controller = ControllerContext.
ParentActionViewContext.RouteData.Values["controller"].ToString();
string action = ControllerContext.
ParentActionViewContext.RouteData.Values["action"].ToString();
if (controller == "Home" && action == "Index")
return Content("");
else
return PartialView("_Menu");
}
我的 _layout.cshtml 如下:
<nav>
@Html.Action("NavigationMenu","Partial")
</nav>
但是,我收到一个调试错误,说明:
System.Web.HttpException: The controller for path '/' was not found or does not implement IController.
在 layout.cshtml 文件中会引发此错误。这应该如何补救?
