I cannot find it in the archives or in the documentation.

I wonder if there is a way to know the outlet number of a selected 

object in a patch via script or javascript?

Thanks,

Do you mean number boxes? cos you can get all this info easy as Pie with Autopattr and pattrstorage. Just put these two in your document and you can save any figures etc as a text document?

If this is what you need and you need any more help let me know.

Hello, I'm developing something where I also need to know the number of 'inlets' and 'outlets' of a certain object. As it has been 17 years now, I wonder if there is a way to do it using 'javascript' on Max? Thanks!

No direct way to do this. However... allow me to propose a truly grotesque hack for this using Javascript.

Use the Patcher containing "foo" to script creation of connections using a "for" loop for increasing index of the inlet/outlet. You'd could script creation of an arbitrary target Maxobj "bar" for these connections. At some point, this will start reporting errors because you've run out of inlets/outlets. (I don't think an error is thrown in JS here, so you couldn't bail out in a try/catch, unfortunately).

At this point you know you have at least one connection for every inlet/outlet. You can then use Maxobj.patchcords property (from "foo") to get the list of all connections. The MaxobjConnection objects returned have the outlet/inlet indexes, from which you could determine the highest indexed inlet/outlet and thus the number of inlets/outlets.

Delete the "bar" object and all those annoying patchcords will go away.

Thanks a lot Tyler, I'll give it a try and report back ;)

function bang() 
{
    obj = this.patcher.getnamed("mything1");
 
    post('number of inlets:', obj.getboxattr('numinlets') ); post();
    post('number of outlets:', obj.getboxattr('numoutlets') ); post();
    
    return;
}

function bang() 
{
	obj = this.patcher.getnamed("mything1");
 
	post('number of inlets:', obj.getboxattr('numinlets') ); post();
	post('number of outlets:', obj.getboxattr('numoutlets') ); post();
	
	return;
}

AMAZING! Thanks a lot 11OLSEN it works like a charm :)
