Checking if date entered is a weekend

[welshboi]

Hi all, long time reader, first time poster :D

I've got a page i've put together in javascript, and one of the fields takes the date (in dd/mm/yyyy) format.

What I'm trying to do, is if a user enters a date which falls on a weekend (eg, 07/11/2009), then to throw an error.

I've had a play, but i'm very confused and couldn't get anything to work :(

Fingers crossed someone can help :D

Thanks

Create a new Date object from the input and
use its getDay() or getUTCDay() method.

Saturday returns 6, Sunday is 0.

If d is a date object, d.getDay()%6==0 is true if the day is Saturday or Sunday.

I'm using the following script from the site below to check if the date entered is valid first of all, can I be cheeky/a pain and ask where in the script would I add your check?

Thanks

Anywhere within the validation part of the function, though the function itself isn't the best out there. The function doesn't convert to the Date object. Try doing that. For the Date object, see https://developer.mozilla.org/en/Cor...e/Objects/Date.

I'm fairly certain I remember seeing weekend and leapyear detection as a feature when I was checking out this library:

It has a ton of great date related stuff and is the best tool I've found for formatting Date Objects.
