Rails-使用超赞的字体

Question

How can I include a fontawesome icon within my button?

<%= f.submit 'Post', class: 'btn btn-primary btn-large' %>

I tried

<%= f.submit '<i class="icon-ok icon-white"></i>Post'.html_safe, class: 'btn btn-primary btn-large' %>

But it doesn't display the icon properly. Any help would be appreciated.

Answer 1

If you're using Rails 4 or newer, you can pass a block to the submit method and include your HTML in there.

Try this:

<%= f.submit class: 'btn btn-primary btn-large' do %>
  <i class="icon-ok icon-white"></i> Post ...
<% end %>
