Rails 3 has some unobtrusive JavaScript which is pretty cool.

But I was wondering what the best way is to include additional JavaScript for a particular page.

For example, where I might have previously done:

<%= f.radio_button :rating, 'positive', :onclick => $('some_div').show(); %>

We can now make it unobtrusive with something like

<%= f.radio_button :rating, 'positive' %>



# then in some other file

$('user_rating_positive').click(function() {

  $('some_div').show();

}

So I guess my question is where/how to include that JavaScript? I don’t want to fill up the application.js file because this JavaScript is only applicable to this one view. Should I include a custom JavaScript file for each page somehow, or stick it in an instance variable that the header looks for?
