Question

I was trying out a regex to “partial match” (any place in the string):

abcd1234 1a2b

I searched for a regex and found this:

/^(?=.*\d)(?=.*[a-zA-Z])$/

But it accepts only alphanumeric; abcd123!@#$ is not matched.

How can this be fixed?

Answer 1

How about this?

/^.*[a-zA-Z].*\d.*|.*\d.*[a-zA-Z].*$/

This should match either:

• an alphabetic character somewhere, followed by a numeric character somewhere, with any number of other types of characters on either side or between them; or
• the other way around (numeric followed by alphabetic)
