redefined method doit().

Hi,
I'll bet this is the problem line:
this.minimize(this.doit);
You're assuming that 'this' is somehow bound to 'doit' when you pass
the reference. It isn't. When you later call fun(), 'this' is not
set to what you think it is within the call. JavaScript functions are
functions, not
Hi marioosh,
TJ is right, when you call the doit function via fun, the 'this' value
is equal to Object window.
So you need a little more binding to resolve your problem:
replace the call to this.minimize(this.doit); by this.minimize
(this.doit.bind(this));
