javascript - Regular Expression For At Least One Number

How would you create a regular expression for a value that should contain at least one number? The user can enter any special character, letter etc., but should contain at least one number.

I tried with pattern="[w+]{6,20}" and

(?=.*d)(*[a-z])(*[A-Z]).{6,20}

Neither are working.

Try using this pattern

.*[0-9].*

For 6 to 20 use this

^(?=.*d).{6,20}$
