Hello,
I’ve been trying to validate US numbers for days now and would really appreciate your help . My code is bellow and I still have 3 more types of numbers to validate.
telephoneCheck(“1 555)555-5555”)
telephoneCheck(“555)-555-5555”)
telephoneCheck("(555-555-5555")
those 3 must return false
my code so far…
function telephoneCheck(str) {
var phoneRegex = /^([1]\s?)?\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/;
if (phoneRegex.test(str)) {
return true;
} else {
return false;
}
}
telephoneCheck("555-555-5555");
