[jQuery] Ajax with jquery, $.post or $.getJson


Till now I used a function I write myself to send via post the vars from
client to server, and then (in the php file) I compose a json object to
resend to the client, and I evaluate it.
Now I'm tryng jquery, and I'm taking a look to:
$.post (with this one I can continue sending data from client to server
via post, but I've to evaluate the returned object).
$.getJson(with this one I can't send data from client to server via
post, but I don't have to evaluate the returned object).
It doesn't exist something like $.postJson??
Thank you.
