So cos’ jQuery, ma sul mio app/assets/javascript/application.js noto  
questa simpatica riga che richiama questo simpatico concetto a me  
sconosciuto T-T

_//= require jquery\_ujs_

che cosa ? Che cosa ci faccio?

UJS sta per Unobtrusive JavaScript, ti consiglio di dare uno sguardo  
qui:

- home page del progetto:  
[GitHub - rails/jquery-ujs: Ruby on Rails unobtrusive scripting adapter for jQuery](https://github.com/rails/jquery-ujs)

- un ottimo articolo che spiega di cosa si tratta:  
[Unobtrusive JavaScript in Rails 3 — Simone Carletti](http://www.simonecarletti.com/blog/2010/06/unobtrusive-javascript-in-rails-3/)

ciao,  
A.

Credo sia questo: [GitHub - rails/jquery-ujs: Ruby on Rails unobtrusive scripting adapter for jQuery](https://github.com/rails/jquery-ujs)

Occhio che se stai usando rails 3.1 credo vadano tolti, cfr:

Grazie, credo di aver intuito cosa sia, ma qualcosa fatto apposta per  
Rails, nel senso evita di inserire nell’output html riferimenti diretti  
al  
javascript grazie a jQuery… (cosa sto dicendo? :O)

btw, essendo una cosa automatica direi che non me ne dovrei preoccupare  
pi  
di tanto 😛
