ruby-on-rails - Rails 中远程 ajax 调用中的图标标记 <i>

Question

我想使用 bootstrap css 中的新 Icon 标签在 Rails 3.1.1 中进行远程调用

这是我的原始代码:

<%=link_to(image_tag("/assets/icons/sub_blue_down.png", :class => "points_arrow"),        
vote_down_politician_path(pending_discussions, :politician_id  =>   
pending_discussions.politician_id), :remote=> true, :method => :post) %>

我想用这个:

<i class="icon-minus-sign"></i>

代替图像标签

这是我的尝试，但不起作用:

<%= link_to  ' <i class="icon-plus-sign"></i>', 
vote_up_politician_path(pending_discussions, :politician_id  =>    
pending_discussions.politician_id), :remote=> true, :method => :post%>

Answer 1

您应该使用以下语法:

<%= link_to vote_up_politician_path(pending_discussions, :politician_id  =>    
pending_discussions.politician_id), :remote=> true, :method => :post do%>
  <i class="icon-plus-sign"></i>
<% end %>
