differentiate between textbutton toggle and button with js?

    Is it possible to get the mode of a textbutton in javascript? Working from the "patchdescribe.js" in the example, we can find all the textbuttons in a patch, but is it possible to parse out the toggles vs. the momentaries? I've tried this, however, "b.mode" doesn't really give me something I can use. It's a jsobject, and it's not really clear how to extract the actual value of the mode so I know if it is a toggle or not.:
    function bang() { this.patcher.apply(iterfun); }
    function iterfun(b) { //post("nclass",b.maxclass); if(b.maxclass=="textbutton"){ post("n----"); for(i in b){ post("nb",i,b[i]); } if(b.mode){ post("ntog",b.mode); }else{ post("nmom",b.mode); } } return true; } iterfun.local=1; // keep private

      Try using the getattr() method, here's a quick example:
      var modes = ["button","toggle"];

function bang() {
    this.patcher.apply(iterbutton);
}

function iterbutton(a) {
    if(a.maxclass == "textbutton") {
        post(modes[a.getattr("mode")],"n");
    }
}

      Ah, great, thank you! Is getattr documented somewhere? I was looking for something like that in the docs and found nothing.

      I'm not entirely sure it is, maybe somewhere in the PDF documentation that came with Max4, either that or I learned about it somewhere here on the forum. It does have a few caveats, but if you're working mainly with UI objects you shouldn't really get stuck.
