Phone number validation including country code with a regex in Javascript-CodePudding

I am trying to apply a phone number masking including country code in below format.

 1(999)99-9999

I am using this regex :

const re = /^[(]{0,1}[0-9]{3}[)]{0,1}[-\s\.]{0,1}[0-9]{3}[-\s\.]{0,1}[0-9]{4}$/
console.log(re.test(` 1(999)99-9999`))

but my validation fails.

CodePudding user response：

You can use

^\ ?\d \(\d{3}\)\d{2}[-\s\.]\d{4}$

JavaScript Example

function isValid(phone) {
  return /^\ ?\d \(\d{3}\)\d{2}[-\s\.]\d{4}$/.test(phone);
}

console.log(isValid(" 1(999)99-9999"));
console.log(isValid(" 1(999)99 9999"));
console.log(isValid(" 1(999)99.9999"));
