A JSONP request is not done with an XMLHttpRequest object, otherwise
it couldn't be done cross-domain. You can't do it async and you can't
use a .responseText property because there isn't one. The docs link to
a site that explains the concept behind JSONP:
http://bob.pythonmac.org/archives/2005/12/05/remote-json-jsonp/The docs could use more clarification on this; JSONP is close enough
in spirit that it can fit in the $.ajax call, but a lot of the options
there don't apply to JSONP. I made a few changes a while back but more
could be done; suggestions welcome!
