[jQuery] Re: Invalid Json Primitive

Since you're not making a cross-domain request, why are you using JSONP
instead of regular JSON? I would think you would just use JSON.

JSONP uses a <script> element instead of XMLHttpRequest, so most of the Ajax
parameters like the beforeSend and error functions don't apply.

I don't know what the "Invalid Json Primitive" message means or where it's
coming from, though. That's not part of jQuery.
