Phone validation regex

Question

I\'m using this pattern to check the validation of a phone number

^[0-9\\-\\+]{9,15}$

It\'s works for 0771234567 and +0

Answer 1

The following regex matches a '+' followed by n digits


    var mobileNumber = "+18005551212";
    var regex = new RegExp("^\\+[0-9]*$");
    var OK = regex.test(mobileNumber);

    if (OK) {
      console.log("is a phone number");
    } else {
      console.log("is NOT a phone number");  
    }
