Get dhtmlx Object by ID

Is it possible to get a dhtmlx Object (e.g. dhtmlxTabbar) by it’s id?
Say, I’ve got the object’s div’s id (e.g. dhxTabbarObj_8EvHo5PedY9o) and want to get the dhtmlx Object for interaction purposes - how would I accomplish this?

When you defind your (i.e.) dhtmlxTabbar object, you use the definition i.e.

var tabbar = new dhtmlXTabBar("userTab", "top");

Then you can operate with “tabbar” variable
