Using AJAX to load controller?

[eluser]future2012[/eluser]
Hi again
Since a couple of days I were trying to process controller file through many ajax frameworks functions so it could load page in background and display response in a little pop-up - with no results.
I'd like to use it for voting system.

Schematic:
ENTRIES.php(controller+view) -> "It's good" BUTTON click -> ajax action(run "VOTES.php?action=good" in background) -> show response in popup/div (anything without refresh...)

Thanks in advance
