Rails 4: Disable submit button after click

Question

I have a form_tag(foo_path(@foo), remote: true, id: \'foo-form\' form and a submit button submit_tag (\"Submit\", :id => \"foo-submit\")

<

Answer 1

An alternative to the submit_tag is the button_tag. The button_tag allows you to add a font awesome spinner.

<%= button_tag 'Submit', class: 'btn btn-primary', 
      data: { disable_with: "
       Submitting Changes..."} %>
