How do I create different event behaviors for touch/click

In the onEventClick and onEventClicked events, you can access the original event as args.originalEvent.

Using the original event object, you can check if the source was a touch event:

onEventClick: (args) => {
  const touch = !!args.originalEvent.changedTouches;
  // ...
},

I’m having some difficulties displaying the menu on touch. inside my touch handling, I am trying to show my menu using the show command and it does not seem to work. Is there something I am doing wrong?

var menuA = new DayPilot.Menu({
  //menu items here
});

dp.onEventClick = function(args) {
   if (!!args.originalEvent.changedTouches) {
      menuA.show(args.e);
   }
   else { 
       //do something else
   }
};
