Maciej,

link_to_remote offers fallback for js-challenged browsers, so this
code would do what you need :(untested)
<%= link_to_remote "Delete",
{:url => {:action => "delete", :id => id} }, ##
<-- if JS available
{:href => url_for(:action => "delete",:id => id)} ##
<- if NO JS
%>
, and in the controller you''d use ''respond_to'' to
handle both calls
within one action.
