Help on regex for phone number format XXX-XXX-XXXX

[dianeramos]

We have a requirement to have a standard format for the phone number field to be XXX-XXX-XXXX (with hyphens). Do you have any suggestions how i can achieve this by validation regex?

Thank you in advance

Try Below Code to convert Phone Number in xxx-xxx-xxxx

var pattern = /[^a-zA-Z0-9]/g;

        var cleanPhoneNum = phoneNum.replace(pattern, "");

        var formatPhn = cleanPhoneNum.substring(0,3)+"-"+cleanPhoneNum.substring(3,6)+"-"+cleanPhoneNum.substring(6,11);

Please mark correct if you find the above solution helpful. 🙂
