Question

I want a regular expression that check string must contain least an alphabet [a-zA-Z] or a digit. All other special characters are allowed, but only special characters or only spaces or only spaces with special characters will now be accepted.

I have tried /\b(?=[A-Z]*[0-9])(?=[0-9]*[A-Z])[\s\S]\b/i and ^(a-zA-Z0-9).*[\s\S]*$ and ^(a-zA-Z0-9).*[\s].*[\S]*$ etc. But its not working. Awaiting for your valuable response.

Thanks

Answer 1

^(?=.*[\w\d]).+

This pattern will fail if there is not at least one character or one digit with any combination of special characters and spaces.
