Question

Anyone had luck with doing multiquery through javascript API or ajax?

Answer 1

I have successfully done this, although I had a bit of trouble at first with the documentation only having a php example.

Just make sure you are attaching the queries json as the 2nd parameter in the api call rather than as a query string like in the php sample. That is:

FB.api('/fql', {q:{"query1":"SELECT uid, rsvp_status FROM event_member WHERE eid=12345678","query2":"SELECT name, url, pic FROM profile WHERE id IN (SELECT uid FROM #query1)"}}, 
function(response) {
    // handle response
});
