Facebook Auto like Script

I'm looking for a non-iframe facebook autolike script. I already have several facebook autolike scripts that use the iframe method. It works when the visitor on my dot com website clicks on something and it autolikes my facebook fan page if that visitor is currently logged into facebook. Lately I've seen websites that are using a new autolike script that doesn't require the visitor to click on anything to get the autolike to work. The autolike function takes place as soon as the page loads. This is the script I'm looking for.
