Question

Does a function exist in ASP equivalent to function_exists() in PHP?

How about an equivalent to call_user_func()?

Answer 1

you could do this with a trick:

public function getFunction(functionName)
    set getFunction = nothing
    on error resume next
    set getFunction = getRef(functionName)
    on error goto 0
end function

dim func : set func = getFunction("myFunction")
if not func is nothing then
    ' call "myFunction"
    func
else
    ' "myFunction" does not exist
end if
