You'd need to use simplejson.loads, for example if you'd pass the anSelected array as arr you'd use something like this

from django.utils import simplejson

array = simplejson.loads(request.POST['arr'])
try:
    ModelName.objects.filter(pk__in=array).delete()
except:
    return HttpResponse(simplejson.dumps({'ok': False}))
return HttpResponse(simplejson.dumps({'ok': True}))

and in your javascript this something along these lines:

$.post(
    '/delete/',
    {arr: anSelected},
    function(data){
        if(data.ok){
            //Everything went smoothly
        }else{
            //Something failed, you can send extra info from django like the name of the exception thrown if you'd want and display it
        }
    }
);
