Add confirm: "Sure?" to f.submit

javascript ruby-on-rails form-submit form-for

Add this onsubmit function to your form helper

<%= form_for(...  , html: {:onsubmit => "return confirm('Are you sure?');" }) do |f| %>

If you have jQuery and want to do it un-obstructively, you can do inside of document ready

$('#my-form').submit(function() {  return confirm('Are you sure?');})
