Not sure, but looks like an extra closing bracket in line 9 of the ajax code

Hi buddies, I have a POST request from ajax. At the backend some records are updated in the django view, this is done fine but an error comes up and the page isnt reloaded.

**This is the error:**

> SyntaxError: Unexpected token O in JSON at position 0

**This is the ajax:**

    $.ajax({
    headers: { "X-CSRFToken": token },
    "url": '/articulos/massup/', "type": "POST",
    "dataType": "json", data: data,
    success: function(e){
    if(e="OK"){
    location.reload(true);
    }
    },
    error: function(a,b,c){
    alert(c);
    }
    });
    });

**Thi is the view:**

    @csrf_exempt
    def massup(request):
        template_name = "articulos/articulos_ok.html"  
        contexto={}  
        if request.method=="GET":  
            cat = Articulos.objects.all().order_by("codigo")  
            contexto={"obj":cat}  
        if request.method=="POST":  
            codigos=request.POST.getlist("codigos[]")
            porcentaje = codigos[0]#el primer elemento de la lista es el porcentaje
            porcentaje=Decimal(porcentaje)
            codigos= [int(x) for x in codigos]#Convierte la lista en integer
            art_change = Articulos.objects.filter(pk__in=codigos)
            i=0
            for item in art_change:
                if i!=0: #Excluye el primer item ( el porcentaje)
                    precioant=item.precio
                    precionuevo=(precioant + (porcentaje * precioant/100))
                    item.precio=precionuevo
                    item.save()
                i=i+1
            return HttpResponse("OK")
        return render(request
