Re: Returning array of integers as part of json dump, how to access in Javascript

2010-02-14 Thread robinne 
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.

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?

I put in wrong variable name:

> array of integers.

should be...

var PIDS = obj.PythonList;

Returning array of integers as part of json dump, how to access in Javascript

2010-02-13 Thread robinne 
I am trying to pass an array of integers from a view to javascript in
an ajax call.

I know how to return json dump from a View so that javascript can
access it as an object like this:

VIEW
response_dict = {"PythonList": MyList, "EditType": edittype}
return HttpResponse(simplejson.dumps(response_dict), mimetype='text/
javascript')

where MyList is a... python list created by:
MyList = []
for p in packages:
MyList.append(p.id)

in javascript, I can access the json by:
var obj = YAHOO.lang.JSON.parse(o.responseText);
var PIDS = obj.PackageIDS; //this brings back 3,2 for example, an
array of integers.

I cannot get at PIDS as an array in javascript. When I try to convert
to an array, the first item in the array is always all values (3,2)
instead of just the first one (3). The most simplistic attempt at this
was:

var jArray = [obj.PythonList]

Any suggestions?
