The scope is private, so you have two options:
a - change ajax method code, assigning the last jsonp call to a global
object, e.g. jQuery ( jQuery.lastJSONP = jsonp = "jsonp" + jsc++; )
b - use a list of possible JSONP calls and compare the difference.
Last point could be something like:
function jsonpList(){
var found = [], key;
for(key in window)
if(/^jsonp[0-9]+$/.test(key))
found.push(key);
return found;
};
function jsonpDiff(listBefore, listAfter){
if(2 < arguments.length)
listAfter = arguments[2];
return listAfter.join("|").replace(new RegExp(listBefore.join("|"),
"g"), "").replace(/\|+/g, "|").replace(/^\|+|\|+$/g, "").split("|")
};
the first function returns a list of active/assigned jsonp calls, while the
second one compare two lists and return a list with differences.
A procedural example could be this one:
var beforeCall = jsonpList();
// perform here your jsonp call via jQuery
var afterCall = jsonpList();
var lastJSONPCallKey = jsonpDiff(beforeCall, afterCall)[0];
alert(window[lastJSONPCallKey]); // jsonp callback
A more tricky way to obtain the key for a single element could be this one:
var lastJSONPCallKey = jsonpDiff(jsonpList(), $.ajax(/*JSONP req info*/),
jsonpList())[0];
Kind Regards.
