Hi all
I'm working on a JavaScript solution to expire some pages. Once a
certain date has arrived, the page will have expired and the user will
be redirected to a "the page you're trying to view has expired" page.
However, to try and be a little more helpful, I'd like to show a message
on the screen that says something like "this page will expire in 5 days
- please contact the document owner". I've got part of the way there,
but I can't work out how to take 2 dates away from each other to give a
value left in days. So far, I've got this, which works:
function checkexpired()
{
var expireDate
var todaysDate
expireDate = new Date("September 28, 2002") //this is the date the page
expires.
todaysDate = new Date() //this is today's date
if (todaysDate > expireDate)
{
location.href="http://www.foo.com" //this is the redirection page
}
}
Can someone point me in the direction of the rest?
Thanks
Francis
