Answer 1

You can try this one.

window.oncontextmenu = function () {
  showCustomMenu();
  return false;     // cancel default menu
}

on right click every browser has default menu for refreshing page, printing, saving and lot more but you can try this one and may be it will prevent default action and add your custom. please write down answer if it will help you.
