get today's date and compare to txt Field

P: n/a
I have an asp page that uses a calendar.js (pop-up) file to add an
exact date format in the text field (txtDDate). My problem is I need
some javascript that sets an alert that does not allow them to select
today.
example:
var dtToday = Date()
if(document.frmSoftware.txtDDate.value == dtToday)
{
alert("You cannot select same day distributions. Please enter a new
value in the \"Delivery Date\" field.");
return false
}
But dtToday seems to be blank....How can I get dtToday value? Also,
when I set the dtToday value outside javascript and used a
Response.Write to see what format Date() came up with - it gave me
1/24/2005 - but the calendar pop-up gives me 01/24/2005....could this
also be the issue?
Thanks in advance!

You'll probably get better/quicker help by posting in a client-side
scripting newsgroup such as .scripting.jscript. ASP is server-side code.

yeah - I posted there first, but didn't get a response - was hoping
that someone on this end would have an idea :(

Thanks

When? I don't see it there. Are talking about the same place?
microsoft.public.scripting.jscript?

If you don't get a response in a reasonable amount of time (~10 hrs on a
weekend, maybe 5 hrs during the week), it can't hurt to reply to your post
and ask if you've failed to provide information needed to answer your
question, or if anyone can suggest an alternative newsgroup to use if the
current one is not appropriate.

Never simply repost your original question without supplying additional
information that was not supplied in the original post.

As Bob suggests, a client-side scripting site would be better. But, If it
were me, I would modify the calendar script to not allow today to be
selected.

Bob,
Sorry - I posted it in microsoft.comp.lang.javascript - but at this
point, I don't want to post it yet again in fear of making people angry
for posting in several different areas :(

It looks like the code is already in place:
if (!this.dt_current) return alert ("Invalid date selected: You cannot
select same day distributions.");
Why it is not working I cannot determine without going through the operation
of the script. Unfortunately I cannot devote that much time. Maybe someone
else can spot the problem more quickly.

Yeah - I added that piece myself thinking that's what I needed to
do.... but it's not working so I figured I had it in the wrong place.
Thanks for looking anyway...
