I'm a .NET guy and don't know the syntax for PHP, but maybe I could
put it in plain terms
- variable "CallBackName" = value of "callback" (which jQuery will
replace "?" with "jsonpNNNNNNN" where NNNNNN is a timestamp just to be
random
- variable MyResults is an object that is expressed in a JSON string
(i know that it's easy to write/convert-to JSON in php but I don't
know the specifics)
- If there is a CallBackName value, then write out
CallBackName( my JSON result )
otherwise, just write out
my JSON result
So in html if i had
$.getJSON("local_call.php", ......)
i'd return from the server
{ foo: "1", bar: "2"}
but if i had
$.getJSON("http://remoteserver/local_call.php?callback=?";, ......)
jQuery would replace "?" with something like "jsonp2345654345", so my
code would return
jsonp2345654345( { foo: "1", bar: "2"} )
the example on the jQuery docs under .getJSON (using Flickr) is a
great thing to read.... and the article @ IBM that is inside my
previous link is an excellent overview as well..... once you
understand how it works, that makes it easy :-)
