Hi,
Apologies in advance if I've misunderstood.
> How do I reference these returned hash values?
But it's no longer a Hash. You've converted it to a string using
Hash#toJSON[1]. If you want it to be a Hash, don't convert it to a
string. Change this:
return $H({x: w, y: h}).toJSON();
to:
return $H({x: w, y: h});
...and then you can use the values via Hash#get[2], e.g., fb.offSet.get
('x').
But taking things further: Why make it a Hash? Why not just use a
POJO? (Plain Old JavaScript Object) If you make that line:
return {x: w, y: h};
...then you can use the properties directly (fb.offSet.x) the way you
tried to initially.
