I am trying to drive my client app from the server side by sending over

Sending over "alert('hi mom')" works great.

Sending over "alert('answer='+answer42)" where answer42 is a global var
(bound to 42) does nothing, not even alert me with answer=undefined, not
even cause an error in chrome or ff debuggers.

Hard to believe, but I have been back and forth a few times checking my
sanity.

Is what I am attempting doable? ie, Ship code over that knows about code
in the client environment?

I guess my next try will be eval, but what I am thinking is that that is
prolly the same thing and what I am seeing is that (like Lisp) eval
happens in a separate null environment. Just guessing tho. Even in a
null environment I would expect answer=undefined.

Aha! Using eval produces an undefined error (but I was calling a
function defined in normal client-side JS, not referencing a global var).

Examples and doc I am finding on eval are not encouraging, either.

Give it up?


Please.
