Validate phone number with JavaScript

Question

I found this code in some website, and it works perfectly. It validates that the phone number is in one of these formats:
(123) 456-7890 or 123-

Answer 1

try this

/^(\+{0,})(\d{0,})([(]{1}\d{1,3}[)]{0,}){0,}(\s?\d+|\+\d{2,3}\s{1}\d+|\d+){1}[\s|-]?\d+([\s|-]?\d+){1,2}(\s){0,}$/gm

valid formats

• (123) 456-7890
• (123)456-7890
• 123-456-7890
• 1234567890
