Re: Returning array of integers as part of json dump, how to access in Javascript
I put in wrong variable name:

should be...
var PIDS = obj.PythonList;

Re: Returning array of integers as part of json dump, how to access in Javascript
Unfortunately your question is not clear, and this "clarification"
does not really help matters. As far as I can tell, obj.PythonList is
already an array. If you do:
jArray = [obj.PythonList]
then yes, jArray[0] is indeed the whole contents of obj.PythonList.
But I don't understand why you want to do this - why not just
obj.PythonList[0] which should be 3?

Re: Returning array of integers as part of json dump, how to access in Javascript
Yea, that was it. I guess I wasn't quite clear on what was getting
passed back from the ajax call. I didn't realize obj.PythonList was
already a javascript array.
Thanks for your response, sorry my code wasn't very clear.
