添加字体真棒图标到rails提交

Question

我在表单中有一个f.submit。我想为它添加一个字体真棒图标。但我不能。

<%= f.submit "Register", class: "button my-button", id: "register-button" %>

如何添加字体真棒图标<i class="fa fa-lock" aria-hidden="true"></i>？

Answer 1

另一种选择是button_tag

<%= button_tag type: 'submit', class: "button my-button", id: "register-button" do %>
        <i class="fa fa-lock" aria-hidden="true"></i>
    <% end %>

Answer 2

使用gem font-awesome

<%= f.button fa_icon("lock", text: "Register"), class: "button my-button", id: "register-button" %>

使用普通的Rails：

 <%= f.button'<i class="fa fa-lock" aria-hidden="true"></i> Register'.html_safe, class: "button my-button", id: "register-button" %>
