link_to :confirm displays popup twice

Question

This tag with rails 3

<%= link_to \'Destroy\', item, :method => :delete,:confirm=>\'Are you sure?\' %>

produces this html

Answer 1

I copy this solution from another post, but this is what worked for me (rails 5)

"remove jquery_ujs from your application.js as rails_ujs is enough for later rails version."

I had included: //= require jquery //= require jquery-ujs //= require rails-ujs

and after deleting it, all works fine. Solution from: Why am I getting a JQuery alert twice in Rails?
