如何将铁路中的一条连接标记为“活性”?
原标题:How to mark a link in a layout menu as "active" in rails?

我有一句话,在我的布局/申请中填满了链接,希望目前的位置与“积极”相挂钩。

现在使用:

<%= link_to  About Us , { :controller =>  aboutus  }, :class => "menu#{  active  if params[:controller] ==  aboutus }" %>

但是,这对我来说是一种 pre。

没有人有更好的想法?

最佳回答

您可以采用类似于“联系”的助手方法。

其名称为“联系_to_unless_ Current”。

问题回答

<代码>link_to_unless_ Current 这种方法实际上不会产生联系,也不会增加一个活跃的类别。 如果你仍然愿意这样做,你可以使用<代码>当值_page方法,核对本页是否与你指明的路线相吻合:

<ul id="main_nav">
  <li><%= link_to "Search", search_path, :class => ( active  if current_page?(search_path)) %></li>
</ul>

或者,如果你想在总结要素上增加这一类别:

<li class="<%=  active  if current_page?(search_path) %>">
  <%= link_to "Search", search_path %>
</li>

一条带有li子扎根的道路的范例,即试图用 content子做,但如果情况如此,则不会uck。

<li<%= " class= active ".html_safe if current_page?(root_path) %>>
    <%= link_to "Home", root_path %>
</li>
