A quick tip on generating a button_to with html_safe and disable_with:

<%= button_to some_path, method: :post, class: 'btn btn-md btn-primary', "data-disable-with": '<span class="fa fa-2x fa-spinner fa-spin"></span>'.html_safe do %>
  <span class="fa fa-2x fa-facebook-square"></span>
<% end %>

Answer 2

If using simple_form:

<%= f.button :button, 
             'Save', 
             class: 'my-class', 
             data: { 
               disable_with: '<i class="fa fa-spinner fa-spin"></i>'
             } %>

Answer 3

You should try to change submit_tag to button_tag, something like this:

<%= button_tag "Go!", class: "btn btn-transparent", 'data-disable-with' => "<i class='fa fa-spinner fa-spin'></i> Searching...".html_safe %>

I've been using Rails for almost 10 years and I just stumbled across disable_with... neat!

You may also use the content_tag helper if you'd rather not insert raw HTML... for example (Simple Form):

= form.button :button,
              t('.submit'),
              class: 'btn btn-primary btn-block', \
              data: { \
                disable_with: [
                  content_tag(:span, '', class: 'spinner-grow spinner-grow-sm'), \
                  content_tag(:span,'Please wait...') \
                ].join \
              }

Of course its probably cleaner to refactor into a helper...

# frozen_string_literal: true

module ApplicationHelper # :nodoc:
  def disable_with_element(text = t('please_wait'))
    [
      content_tag(:span, '', class: 'spinner-grow spinner-grow-sm'),
      content_tag(:span, text)
    ].join
  end
end

= form.button :button,
              t('.submit'),
              class: 'btn btn-primary btn-block', \
              data: { \
                disable_with: disable_with_element \
              }

Note, I'm using Simple Form and Slim in these examples.
