Answer 1

I'm not sure to understand your question but you can try this:

<%= select_tag "name", options_for_select(@user.names.map {|c| [c.firstname,c.id]}),:onchange =>"document.location.href='/names/'+this.value" %>

Thereby, the selected value is used during the onchange event.

Try this

<%= select_tag "name", 
   options_for_select(@user.names.map {|c| [c.firstname,c.id]}),
   :onchange => "document.location.href=/names/ + $(this).value" %>
