JavaScript
1.Please use javascript to create a class of right-Click-Menu that base on the web.
2.make this class extend to a new class that can expand a second menu.
3.make this class extend to a new class that can expand a limitless menu.
explanation：for example, like the windows, when we click the right button of the mouse on the desk, that will pop-up a menu, that is what we
call the right-click-menu. watch carefully, our right-click-menu is base on the web but not the others, also not like the fixed navigation.
