[thelist] check existence of a javascript function

[Emily E Liang]

Richard, Liorean, Jeff, Andrew, David, Matt, Filip, Alliax,

Thank you all very much for responding to my question and sharing your
brilliant ideas.   The 3 ways listed in my original mail worked after I
removed the () from the end of the function name.  Richard's method and
the typeof method also worked well.

Thanks everyone!

Emily
