Select group with label

Question

hi, I try to select group on page
var doc = app.activeDocument;
var myModul = doc.groups.item("modul");
//var myModul = doc.groups[0];
//$.writeln("ID: "+myModul.id);
$.writeln("Constructor: "+myModul.constructor.name);
//$.writeln("typ: "+typeof(myModul));
app.select(myModul);
Why this doesn't work ?

Answer 1

try below code
var doc = app.activeDocument;
var myPage = doc.pages
var myModul = doc.groups.item("modul");
for(var i = 0;  myPage.length>i ;i++){
      var allItems =myPage[i].allPageItems
       for(var j=0;j<allItems.length;j++)
                    var myGroup = allItems[j];
                        if(myGroup.label =="modul"){
                            $.writeln("Constructor: "+myGroup.constructor.name);
                                app.select(myGroup);
