Posting information and retrieving results using Ajax

[awise107]

I would like to using (Ajax) PHP or Javascript, Post information to http://en.lernu.net/cgi-bin/vortaro.pl then read the results back (Not from lernu.net).I am trying to learn Ajax, PHP + Javascript, Nobody there know's how to help me. I would very much like doing this without touching Lernu's code, So if there is a way to do it all on my code, that would be great!
