Is there a way to pass a javascript variable to ruby code?

For example in my index.html.erb if I have a javascript array holding an array of selected posts such as:

var selected = [];

How do I pass this variable into ruby code on the same page:

<% Post.recent(selected[]).each do |post| %> ..... <% end %>

Hey Nano,

You need to contact the rails server with your variable somehow. This usually involves either an AJAX request or a POST/PUT to the server. There's no immediate way to get access to variables the way you describe :(
