Passing a jsobject from one js instance to another. Different behaviour in Max6

Feb 24 2012 | 5:52 pm

I’ve searched the forums and can’t find a related discussion, so here goes: Basically, I’m passing some information in he form of a simple jsobject from one js instance to another.
Sender: (send_obj.js)

outlets = 1;

function bang() {

	var out_obj = {'name':'Jimmy', 'job':'Driver'};
	outlet(0, out_obj);


Receiver: (recv_obj.js)

outlets = 1;

function receive(in_obj) {
    keys = [];

    for (var key in in_obj) {



In Max5, it works without a problem, whereas in Max6 when I try to inspect the object in the receiver instance, I always get ‘undefined’.

Furthermore, In Max5, when I list the keys, I get ‘name’ and ‘job’ as expected, whereas in Max6 I get 0 1 2 3 4 5 6 7 and if I look at the values, it spells out ‘jsobject’. So it appears that it’s only getting a string containing ‘jsobject’ rather than an actual object?

I’m possibly going to look for another way to pass the information, so if anyone has any suggestions I’m all ears.

Hi Murzz,
In max 6 you can use dictionaries to share simple JSON objects across the JS instances. At least as long these Objects don’t contain code/functions or object classes.

I personally like to work with a simple event-listener structure to pass objects/code around JS in Max. Like this i don’t need to poll for changes and Objects can be passed directly from [js ] to [js ] without going through inlets and outlets.
in this thread (at the end) I recently posted an example of the event/listener construction I use.
