Regular Expression either numeric characters or both alpha-numeric but not only alpha characters

To validate a field that must have both numbers and letters, I could use:

/^([0-9]+[a-zA-Z]+|[a-zA-Z]+[0-9]+)[0-9a-zA-Z]*$/

But I want to additionally accept numeric only strings.

You mean you want at least one number?

You could use look-ahead assertion.

/^(?=.*\d)[a-z\d]*$/i
