Access parent’s parent from javascript object

by

I simply added in first function 

parentThis = this;

and use parentThis in subfunction. Why? Because in JavaScript, objects are soft. A new member can be added to a soft object by simple assignment (not like ie. Java where classical objects are hard. The only way to add a new member to a hard object is to create a new class) More on this here: http://www.crockford.com/javascript/inheritance.html

And also at the end you don’t have to kill or destroy the object. Why I found here: http://bytes.com/topic/javascript/answers/152552-javascript-destroy-object

Hope this helps
