      Setting is as easy as sending a message to the named object with the set or message functions, but retrieving the current information is much more difficult. One idea is to script a [grab] object into place and connect it to a [message] box and back to a dedicated inlet of your [js] object. If you only need this to work in a patching environment you can even parse the JSON text of your patch as demonstrated in this article. However this won't work with anything other than a maxpat file so if you need it to function in a standalone application this method will not work.

      Thanks Luke for your reply. unfortunately, this won't help me much, because i need to get the content of a comment box, and grab can't get it ; (and my js isn't in the same patch...) ok, I'll find a workaround !
      thanks !

      I think you might ask C74 directly, and they should really adapt a bit max objects to your goals in next incremental max version, come on!, what you're working on ( ) is just the future of max!

      Mathieu, did you ever resolve this issue? I am trying to do something similar, retrieving the text of a comment box with JS. Any info of your process or solution would be appreciated!

      no, sorry, I never found a solution, and finally had to give up retrieving content of comment box. :-(

      One way to do this is to load up the patcher as JSON and then parse it for comment boxes.
      Please excuse the roughly hacked out code - hopefully you will get the idea
      var patcher_file = new File(this.patcher.filepath); while (patcher_file.position != patcher_file.eof) { lines += patcher_file.readline(); } patcher_file.close(); var parsed_patcher = JSON.parse(lines); if (parsed_patcher["patcher"]["boxes"][0]["box"]["maxclass"] === "comment") { post(parsed_patcher["patcher"]["boxes"][0]["box"]["text"]);post(); }
