The ticket lives here:
http://dev.jquery.com/ticket/3442
Many thanks to Andrea. I ended up using a simpler but similar
function:
function cancelJSONP() {
for ( var jsonp in window )
if ( jsonp.substr( 0, 5 ) == "jsonp" )
return window[ jsonp ] = function(){};
};
It doesn't do any garbage collection on the window callback or script
tag, but perhaps these will be easier to implement once the ticket is
addressed.
Thanks Andrea and John,
Jed Schmidt
