From the function line, I would half-expect that to have been intended
to write the general HTML string s into the specified frame, in which
case there is a missing (.innerHTML || .somethingElse).

Be careful with it.

X = Y = 3          ; Y++             ; Z = [+X, +Y]     // [3, 4]
X = Y = new Date() ; Y.setTime(3456) ; Z = [+X, +Y]     // [3456, 3456]
