Date and time

[Samir]

Say I put a date and time for like this:
Jun-15-04 21:52:06

Here is the form I am using:
<form>
<p><input type="text" name="T1" size="20"><br>
date</p>
<p><input type="text" name="T2" size="20"><br>
90 days from date</p>
<p><input type="submit" value="Submit" name="B1"></p>
</form>

How could I get to show the date 90 days later to the exact date and time.
I would enter the data in the first box and hit submit to show in the second
box.

TIA

If you're not going to be sending the data to your server,
you shouldn't use a submit element. Use an input of type
"button", instead.

<input type="button"
value="Submit"
onclick="this.f orm.date2.value =plus90(this.fo rm.date1.value) ">

"T1" and "T2" (and "B1") are pretty bad names for form fields.
Why not at least "date1" and "date2"?

As for what the function I've called plus90() should do,
check the date manipulation links referenced in the FAQ:
http://www.jibbering.com/faq/

You may want to rethink the input format.
It's a lot easier if the format is "Jun 15 2004 21:52:06".

A lot??

t = "Jun-15-04 21:52:06"

t = t.replace(/-(\d\d) /," 20$1 ").replace(/-/g," ")

[allows also last century as 19..]

Wrong. Using a submit button may also be useful without a server, if it
is used in an application using only client-side scripting and the required
DOM access methods are for some reason not available or viable. Example:

<http://pointedears.de/scripts/test/ObjectInspector/nightly/latest/index>

It would be more correct to say that using a submit button is not viable
if re-accessing or changing the container element's resource is undesired
which is the case here.

Yes: var firstDate=new Date("Jun 15 2004 21:52:06");

Samir is probably a foreigner (everybody is probably a foreigner on the
Internet). Can one be sure that in all browsers the form "Jun" is
recognised? AFAICS, ECMA is indecisive in such matters (ICBW); and not
all software is compliant with applicable standards - some foreign
software systems are configured with excessive localisation.

Accordingly, I would suggest instead 2004/06/15 21:52:06 xxx
where xxx is either absent, a well-known time zone indicator, or an
offset from GMT. The form is as close to ISO 8601 as my browser will
accept.

Unless users are restricted to odd places like China, Hawaii, Guam, the
ISS, Iceland, Morocco, and Ghana, etc., the OP needs to decide whether
the 90 days are to be of real time or of user's civil time.

Wouldn't

d = new Date(...);
d.setDate(d.get Date() + 90);

be simpler?

Also, getFullYear() is preferable to getYear().

Yes, more concise, but perhaps not as clear to the OP.

Also, getFullYear() is preferable to getYear().

Why, in this case?
