Hide right menu / click from embed html files

Question

I am trying to hide the context menu when embedthere is a right-click event in the html file .

The code that I have works fine when I right-click on the embed window, the menu is no longer hidden.

How can I hide the context menu (in some versions of Safari browser version 9.1.1 (11601.6.17))?

    alert("You've tried to open context menu"); //here you draw your own menu
    e.preventDefault();
  }, false);
} else {
  document.attachEvent('oncontextmenu', function() {
    alert("You've tried to open context menu");
    window.event.returnValue = false;
  });
}
