Date Validation (Preventing future dates)

[jenn1]

Hello,
How do you validate on future dates. I have a form where I don't want things entered ahead of today's date. Anyone have a validation that does this?

Thanks!

On the server it's easy, compare it to cold fusion's now() function.

On the client it's a bit more complicated because you have to use javascript.

Or you could use DatePart. Once the data is submitted check to see if the day is greater than today, if it is send them back to the form.

create javascript date obj that store today date
convert date from from to javascript date obj as well
then you can simple use > or < to check form date is in the future or not.

var today = new Date();
var a = new Date(year,month,day);
if (a > today) alert("no future date is allowed");

hope that can help.
