What is the best way to validate a field as a positive or negative
integer?

How about a zero one? Do you want to allow a floating-point form of a
value which happens to be integer, such as 1e6 or 3.000 ? How about
0xFF ?

OK = /^[+-]?\d+$/.test(field)
tests for optional sign followed by only decimal digits. \d{1,6} might
be preferred, likewise [+- ] .
