Format Phone Numbers

[celley]

i am writing a phone number format in javascript. i have the actual
formatting part working fine (if one enters no (,),-, etc.). i decided
to delve into regular expressions to strip out the punctuation
characters. well, it isn't doing what it is supposed to do and i have
no idea how to make it do what it needs to do. i am going on scraps
from MSDN and some help i got the other day on a js function, which
doesn't help much. anyone help? [sig]<p>Chad Elley<br><a href=mailto:celley@gobcg.com>celley@gobcg.com</a><br>[/sig]

You can either strip special puntuation characters:

s=s.replace(/[()-,. ]*/, '')

of you can strip all except numbers:

s=s.replace(/\D*/, '')

or equivalent:

s=s.replace(/[^0-9]*/, '')

asterisk (*) at the end of patterns needed to slitly faster processing. [sig]<p>Michael Dubner<br>Brainbench MVP/HTML+JavaScript<br>

If you send the phone number through parseInt() it will remove all the formatting for you:

var numberFromInput = "+1 555 123 4567";
var numberWithoutFormatting = parseInt(numberFromInput,10);

By adding the radix of 10 as a second parameter, you specify base 10 for the result. This is important for correct cross-browser support as well as avoiding unexpected results.

Once you have all non-numberic formatting removed this way, you can convert it back to a string and then use string manipulation to re-format it nicely again.

Cheers,
Jeff

Just thought it would make interesting reading for those doing telephone formatting And it's a slow day at work today!
