问题描述
我有一个 ul 的菜单
I have a menu which is a ul
Home | Calendar | Settings
我想突出显示(通过 css 类)菜单中选定的选项卡.
I want to highlight (via a css class) the selected tab in the menu.
某些链接(主页和日历)也有子选项
Some links (Home and Calendar) also have subselections
Home | *Calendar* | Settings
-------------------------
Add event | Edit event
当然,选择编辑事件时,日历仍应突出显示.
Ofcourse when edit event is selected, Calendar should still be highlighted.
我怎样才能最好地使用 rails 和 css 来解决这个问题?
how can I best approach this using rails and css?
谢谢
推荐答案
最简单的方法是检查正在使用哪个控制器.我编造了控制器名称,因此您当然可以用正确的名称替换home"、calendar"和settings".
The simplest way would be to check which controller is being used. I made up controller names, so of course you would replace 'home', 'calendar', and 'settings' with the correct names.
<ul>
<li class="<%= "highlighted" if params[:controller] == "home" %>">Home</li>
<li class="<%= "highlighted" if params[:controller] == "calendar" %>">Calendar</li>
<li class="<%= "highlighted" if params[:controller] == "settings" %>">Settings</li>
</ul>
