Copy, paste, chain, etc. It just works. Well, except in the many cases where it doesn't but they don't "care" about those cases.

That's what I wanted stated clearer as I think an occasional reader may not know about the reserved top-level domain names and the exact valid production of the local part of an email address. -- Stanimir

(Unless you actively want to lose customers). To be maximally helpful, allow [multiple] spaces as separators too. The space bar is the biggest key on a normal keyboard. For pattern validation, /^\s*(\d+)\D+(\d+)\D+(\d+)\s*$/ /^\s*(\d+)(\D+)(\d+)(\2)(\d+)\s*$/ /^\s*(\d+)([/\.-])(\d+)(\2)(\d+)\s*$/ or similar should do, followed by setting the matches into new Date(Y, M-1, D) and reading back the month (needs (\d\d?) for the Day, IIRC) If the application requires a moderately current date, the RegExp could call for (20\d\d) or (201\d) for the year. <URL:http://www.merlyn.demon.co.uk/js-date4.htm> refers. "First name" / Last name" can be inappropriate in some cultures - Chinese and Mongolian, for example, IIRC. Also, how about those who do not use their first name - J. Edgar Hoover, George VI, for example? How about middle initial(s)? And those whose date of birth does not match their birthday? How about those whose date of birth was 1900-02-29? Some may still be alive. -- (c) John Stockton, nr London, UK. ?@merlyn.demon.co.uk Turnpike v6.05. Web <URL:http://www.merlyn.demon.co.uk/> - w.

However, since the length of the month depends on the numbers of the month and year, and also forms should be filled in left to right, top to bottom (if using a Western-type language), you need HTML for Year, Month, Day. What you want should be disregarded. See in Web <URL:http://www.merlyn.demon.co.uk/js-date6.htm>. -- (c) John Stockton, nr London, UK. ?@merlyn.demon.co.uk Turnpike v6.05.
