Hi again. this is how I solved it:
-- helper code:
# support for client side cached requests
def include_cache_request_script
%Q{<script> function cached_request(remote_func, update) {
if($(update).innerHTML == "") { remote_func(); }
else { Element.toggle(update); }
} </script>}
end
def cached_link_to_remote(title, options)
func = "cached_request(function() {#{remote_function(options)};},
'#{options[:update]}')"
link_to_function title, func
end
-- view code:
<%= include_cache_request_script %>
...
...
<%= cached_link_to_remote title, :update => doc_id,
:url => {:action => 'foo', :id =>
item_id } %>
What do you think about it? Have a nice day,
T
