If you can tell me what constitutes a valid domain name then I can write your script.

It is nothing but any web site address, it should be in
www.websitename.com (com/co/org...) format

shara We need a lot more to go on than that. What characters are allowed? What are the length restrictions? What about case? Do you want to require the tripple w? What about the country codes?

I think this should do it:

String.prototype.isDomainName = function () {return this.match(/^www\.\w{2,}\.[a-zA-Z]{2,}$/)}
