if(!document.phone.value.match(/^[\d\/\\\s+-]+$/))

for characters allowed: 0-9, -, /, \, +

This works awesome for 10 digit phone numbers:

var regexObj = /^$?([0-9]{3})$?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/;

if (regexObj.test(subjectString)) {
var formattedPhoneNumber =
subjectString.replace(regexObj, “($1) $2-$3″);
}

What needs to change to allow an extension?

For example, I’d like it to format the phone number to:

(123)456-7890 x123

Thanks, in advance for this!

this site is very helpful.

i’m wondering, given a phone number like this: “+1234567890″; is there a mathematical way to determine the country and area codes? — without looking at the code tables.

what if there exist country codes “1″ , 12″ and “123″ ? how do we figure this out?

Thanks.
