如何基于MVC中的控制器隐藏共享布局中的元素(How do I hide an element in the shared layout based on the controller in MVC)

我的页面主页顶部有一个bootstrap导航栏，里面是文本输入。 我希望它隐藏，直到执行搜索并且用户在results控制器中看到results 。

这是在我的bootstrap导航栏中。

<input type="text" class="form-control" placeholder="Search">

例如：

Hidden: www.example.com/home/index Visible: www.example.com/results

I have a bootstrap navbar at the top of my page main page and inside it is a text input. I want it hidden until a search is performed and the user sees the results in the results controller .

This is inside my bootstrap navbar.

<input type="text" class="form-control" placeholder="Search">

For example:

Hidden: www.example.com/home/index Visible: www.example.com/results

在这种情况下，您实际上不需要将任何特定信息从控制器传递到共享布局。

共享布局可以相应地检查当前路线和行为。

@if (ViewContext.RouteData.Values["Controller"].ToString() == "results") { <input type="text" class="form-control" placeholder="Search"> }

In this case, you actually don't need to pass any specific information from the controller to the shared layout.

The shared layout can inspect the current route and the behave accordingly.

@if (ViewContext.RouteData.Values["Controller"].ToString() == "results") { <input type="text" class="form-control" placeholder="Search"> }
