我有一个下拉菜单,当页面使用 current_page 时它会处于活动状态?像这样的方法:
<ul>
<li class="dropdown">
<a href="javascript:void(0)" class="dropdown-toggle <%= current_page?(company_dropA_path(@company)) || current_page?(company_dropB_path(@company)) || current_page?(company_dropC_path(@company)) || current_page?(company_dropD_path(@company)) ? 'active' : '' %>" data-toggle="dropdown"><%= @company.name %> <b class="caret"></b></a>
<ul class="dropdown-menu">
<li><%= link_to 'Dropdown A', company_dropA_path(@company) %></li>
<li><%= link_to 'Dropdown B', company_dropB_path(@company) %></li>
<li><%= link_to 'Dropdown C', company_dropC_path(@company) %></li>
<li><%= link_to 'Dropdown D', company_dropD_path(@company) %></li>
</ul>
</li>
</ul>
正如您可能注意到的,current_page 变得非常长且凌乱。我怎样才能将其转换为助手?
