Calling you stupid when you do stupid things is a telling a fact, not an expression of any personal frustration I might have. So the problem is on your part, not on mine.

My observation is that Asen did not post code; I guess his `deep` does check prototype chain but it's not something that's been mentioned yet. -- Garrett comp.lang.javascript FAQ: http://jibbering.com/faq/

I just modified the function to accept an optional last parameter of delimiter. So in this case you could just do: $prop(obj, 'property|.property.|[property]', '|') Maybe not as straight-forward as passing multiple arguments, but same difference. Matt Kruse
