I'm new to Javascript in Max, and I'm trying to leverage some existing subpatches from Javascript.

I have a subpatch with at least 1 inlet in my patch, something like this:

I also have a js object in the same patch.

How can I send messages to the subpatch inlets from the js object? I am aware of how to send a message to a built-in object, such as "number" by calling the message method of the object. However, I can't figure out how to send anything to a subpatch.

var subpatch = this.patcher.getnamed("mySubPatch"); // returns object ref of subpatch

subpatch.message(42); // error: doesn't understand 'int'

I tried setting the script name of the subpatch in the inspector, but that does not work either.

A less than ideal workaround is to create a number or message object within the subpatch to act as an inlet, and send messages to them. You can obtain the virtual "inlet" object like this:

numObj = this.patcher.getnamed("mySubPatch").subpatcher().getnamed("inputNumber");

numObj.message(42); // works to set the "inlet" value and invoke subsequent subpatcher logic.

I was hoping to find a more direct way to use existing subpatchers from Javascript.

I think at the moment it's not possible to send messages to sub patchers or bpatchers. 

Your solution is fine, alternatively you can also create a single receiver in the subpatches and send all the messages to it from within JS with the "messnamed" function. 

Then you can route the output as you see fit
