Hi everyone: I,m using the following code and I have some questions

<div id="comment_<%= comment.id.to_s %>"> <%= link_to_remote( "Show Body", :update => "comment_#{comment.id.to_s}", :url => { :action => :show_body, :id => comment }) %> </div></td>

what exactly do :update,:url,:id, I mean what is the action they done??

Other question

Thanks

The official documentation for link_to_remote explains this probably better than I could myself: http://www.railsbrain.com/api/rails-2.3.2/doc/index.html?a=M002467&name=link_to_remote

Basically though, :update is the id of the DOM element to be updated (<div id="comment_#1">...content...</div>. URL in this case is the "show_body" action of the current controller with the id of the current comment.
