David Lovering,
Thanks for your replay, i am try to enlightenment my code.
my goal is i am trying to check if "jml object" has a value or not.
if "jml object" has a value i must create Input Tag again after user click
the button, just like that.
the problem is when i try to check that value for "jml object" with
"function alertvalue(obj,idx)" i expecting value of idx is an object so i am
use "eval function" and the word "undefined" is a mistake(because i do not
know how to check a null value on javascript).
i hope my this mail can be enlightenment
TIA,
andy
