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
        }
    }
);

You could try sometings like this:

$(function(){
    $.post("{% url delete %}", {"ids[]": anSelected}, function(res){
    if(res.ok){
        // remove rows from your table, maybe :)
        // oTable.fnDeleteRow(anSelected);
      }else{
        alert(res.errors); 
      } 
    });
})

On the server:

@ajax_request
def test(request):
    ids = request.POST.getlist("ids[]")
    try:
        Items.objects.filter(id__in=ids).delete()
    except:
        return {"ok": False, "errors": "your error"}
    return {"ok": True}

the @ajax_request decorators is from https://bitbucket.org/offline/django-annoying/wiki/Home and let you return json response.
