Hello Hendrik,
Thank you for your help! I can get the 'ok' in the alert with your code.
However, how do I show the response in the alert? For some reason I am
unable to pass the message back from the view; I keep getting an empty
alert(response).
My view looks like:
def new_session(request):
if not request.is_ajax() or not request.method=='POST':
return HttpResponseNotAllowed(['POST'])
else:
request.session['key'] = json.loads(request.POST.get('details',
'[]'))
return HttpResponse(request.session['key'])
I've also tried "return HttpResponse('ok')", but the 'ok' still didn't get
passed to the load function. What do I do wrong? Any hints would be much
appreciated!
voss
