如何在rails 3中将buttonstrap图标添加到button_to

Question

我的原始代码是

<%= button_to 'Destroy', girl, confirm: 'Are you sure?', :disable_with => 'deleting...', method: :delete, :class => 'btn-mini btn-danger btn'  %>

我想在“Destroy”这个词前添加一个图标。

icon标签就是这个

<i class="icon-pencil icon-white"></i>

我该怎么做？

Answer 1

尝试使用块

<%= link_to girl, confirm: 'Are you sure?', disable_with: 'deleting...', method: :delete, class: 'btn-mini btn-danger btn' do %>
  <i class="icon-pencil icon-white"></i> Destroy
<% end %>
