Receiving output of JS message to object

Javascript

Hi everyone,

since I have discovered the use of JS in MAx4Live my life has gotten new meaning! ;)

Thanks to the forum I am learning fast.

I have found out how to send messages to objects in M4L, so I can easily set values or invoke a bang or other things.

However, sometimes an object spits something out after you send it a message, and I would like to capture that in my code:

if I send this 'getslotlist' via a normal message to my autopattr object I get this as a response:

print: slotlist 1 2 3 4

Now if I do this in my code:

this.patcher.getnamed("slots").message("getslotlist");

This gives me the same print output as above (print: slotlist 1 2 3 4)

now when I add:

post(this.patcher.getnamed("slots").message("getslotlist"));

I get this as output:

js: jsobject -1266632561161856

What piece am I missing to get the response with slotlist?

many thanks!

Or should I maybe use pattr?

It's troubling that it has been over four years since Dennis posted this question with no response because I am having a similar problem. I'm trying to get a message object's text (e.g., "32n") with my JavaScript code and all it ever posts to the Max Console is a similar string of numbers.

This code...

tempoResolution = this.patcher.getnamed("tempoResolution");
post ( tempoResolution.getvalueof() );

…only ever produces something like: js: jsobject -1407374883553280

I only ever get a similar string of numbers in the Max Console when I use this code...

tempoResolution = this.patcher.getnamed("tempoResolution").message;
post ( tempoResolution );

How does one use JavaScript to get the current message displaying in a message object?

It seems like this would be a very common thing for people to do and thus clearly described in all the documentation but I can't seem to find it anywhere.

Thanks for any consideration or responses.

based on maxobjlistener example:

inlets = 1;

outlets = 1;

function bang(){

gc(); // Run garbage collection

var obj;

obj = this.patcher.getnamed("t_res");

new MaxobjListener(obj, t_resCallback);}

function t_resCallback(data){

outlet(0, "t_res = " + data.value);

post ("t_res = " + data.value);

post();}

t_resCallback.local = 1;
