Tell us what’s happening:
Hello,
I’m trying to solve ‘Validate US Telephone Numbers’ algorithm.
My code is below
this code should return true or false
as example
telephoneCheck(“1 **555)555-5555") should return false
telephoneCheck("1(555)555-5555") should return true.
telephoneCheck("(555)**555-5555”) should return true.
telephoneCheck(“1 555 555 5555”) should return true.
with RegExp I’m trying to catch strictle these (555) or 555 parts
I have bolded the phone number part which I’m catching
for this purpose I’m trying this RegExp part
[\D\d{3}\D]? Dose it correct?
But it’s catching …555) or (555… with single quote also
How I’can eliminate this single quote?
Your code so far
function telephoneCheck(str) {
var regexpr = RegExp('^1?\\s?[\\D\\d{3}\\D]?\\d+', 'g');
var test = regexpr.test(str);
//str.match(reg1);
return test;
}
telephoneCheck("1 (655)555 9555");
