JavaScript getter for all properties

Does JavaScript provide a method to access undefined object properties? In PHP the solution is to declare and implement __get() method in class.
Solutions using try { .. } catch { .. } are not sufficient for me, because I already have very large amount of code which actually needs to stay as-is.

You may choose to write a similar functionality and check existing parameters them against the arguments array. I'm not 100% that this will solve your problem.
