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

You use CoffeeScript to do something like these lines:

jQuery ->
  $('.theform').submit ->
    $('input:submit').attr("disabled", true)

This disables the form submit button when the form with class="theform" is submitted. Depending on your need you adjust this to fit with your class/id for the form.
