Must be 18 to register
I need to make a script using javascript that makes an alert saying " You must be 18 to register" if the birthday that entered shows that they are under 18. This may seem easy for other people but Javascript isn't my best subject. If someone can point me in the right direction, it would be greatly appreciated.

I don't do any JavaScript (at all) but I can point you to w3schools.com for all your JavaScript (and other Web Development) learning needs.
There was probably a similar thing when you registered for this very forum. Go to some message boards and go through the registration process, then do view source when you are at the point where it asks you your age. This will shed some light on how the professionals do it. |

Theres no good way to do it in JS, JS requires their system time to be correct, use a server side language like PHP or ASP my friend...

He's right ya know. I suggest doing both actually - the JavaScript will stop them from making a mistake (if it is a mistake), and the PHP will stop anyone (with the wrong system time or disabled JavaScript) from getting through.

If I could do with it PHP i would do it in an instance but i'm doing it for someone who doesn't have access to there server. It's one of those sites that gives out freeforums. That's why i'm required to do it in Javascript.

Fair enough. If people want to get in, they'll just change their DOB anyway.

Do it this way, have a remotely linked JS file set variables for system time from your home server and then write the JS code for 18 auth....
HTML: <script src="http://my.website.wherever.com/scripts/currentTime.js"> currentTime.js: <?php
echo "var month = " . date("m") . ";\n"
echo "var day = " . date("d") . ";\n"
echo "var year = " . date("y") . ";\n"
?>
