How the ratiobutton call function?

Hi everyone

I got this script

  var d=app.dialogs.add({name:”Define Empty Pages”});

  var radioBtns = d.dialogColumns.add().radiobuttonGroups.add();

  radioBtns.radiobuttonControls.add({staticLabel:”Save”,checkedState:true});

  radioBtns.radiobuttonControls.add({staticLabel:”No Save”});

  radioBtns.radiobuttonControls.add({staticLabel:“Exit”});

  if(!d.show()){d.destroy();}

  var saveOption = radioBtns.selectedButton;

            d.destroy();

            var docs = app.documents; 

            for (var i = docs.length-1; i >= 0; i--) { 

                if (docs[i].saved == false) { 

                    docs[i].save(new File(“~/Desktop/myTestDocument” + (i+1) + “.indd”)); 

                    docs[i].close(); 

                } 

                else { 

                    docs[i].close(SaveOptions.NO); 

                } 

            }

for close docs without save, but

I want to remain choice for those unsaved files, so I add open dialog in case for me to decide if I save those unsaved files.

Now, the problem is I don’t know how to let the ratiobutton call function

My aim:

1) If choose “Save” means save unsaved files, but not others

2) If choose “No save” means all files no save

2) If choose “Exit” means unsaved files Exit (remain open) but close others

Thanks

Regard
