Advance Date +15 Days

I have a script...
-----
<SCRIPT language="JavaS cript" type="text/javascript">
<!--
function makeArray() {
for (i = 0; i<makeArray.arg uments.length; i++)
this[i + 1] = makeArray.argum ents[i];
}

function makeArray0() {
for (i = 0; i<makeArray0.ar guments.length; i++)
this[i] = makeArray0.argu ments[i];
}

function y2k(number) { return (number < 1000) ? number + 1900 : number; }

var months = new
makeArray('Janu ary','February' ,'March','April ','May','June', 'July','August' ,'September','O ctober','Novemb er','December') ;
var days = new
makeArray0('Sun day','Monday',' Tuesday','Wedne sday','Thursday ','Friday','Sat urday');

var today = new Date();
var day = days[today.getDay()];
var date = today.getDate( ) + 15;
var month = today.getMonth( ) + 1;
var year = y2k(today.getYe ar());

document.write( months[month] +' ' + date + ', ' + year);
//-->
</SCRIPT>
---

I need this script to advance the document.write by 15 days, as you can see
I tried adding "+ 15"
after the Var Date = today.getDate( ) that works fin until it started
showing 32 days in June
today. LOL.

Can anyone please assist me? Ro****@BeatToBe at.com

Thank you,
Robert

The date constructor can take a number of milliseconds as an argument
to create a date object from. Perhaps this example will be of use:

<script>
var dt = new Date();
var dt2 = new Date(dt.getTime ()+15*24*60*60* 1000);
alert(dt+"\n"+d t2);
</script>

if you find yourself using it a lot, create a Date.prototype

Date.prototype. addDays=functio n(days){
this.setDate(th is.getDate()+da ys)
// do stuff with the revised date object if you want to.
}

Neither of these functions is needed, see below.

var months = new

Relying on the client PC's clock is unreliable, there are other
strategies, read the group FAQ:

<URL:http://www.jibbering.c om/faq>

You can add 15 days directly to the date object:

var today = new Date();
today.setDate(t oday.getDate()+ 15);
var day = days[today.getDay()];
var date = today.getDate( ) + 15;
var month = today.getMonth( ) + 1;
var year = y2k(today.getYe ar());
Delete all the above.
document.write( months[month] +' ' + date + ', ' + year);
document.write(
months[today.getMonth( )] + ' '
+ days[today.getDay()] + ' '
+ today.getFullYe ar()
);
</SCRIPT>

Sorry, but the laugh's on you. The value returned by getDate() is a
number, so adding any other number will give a normal arithmetic
addition.
<script type="text/javascript">

var months = [
'January','Febr uary','March',' April','May','J une',
'July','August' ,'September','O ctober','Novemb er','December'
];

var days = [
'Sunday','Monda y','Tuesday','W ednesday',
'Thursday','Fri day','Saturday'
];

var today = new Date();
today.setDate(t oday.getDate()+ 15);

document.write(
days[today.getDay()] + ', '
+ today.getDate() + ' '
+ months[today.getMonth( )] + ', '
+ today.getFullYe ar()
);
</script>

Forgot about setDate, yeah, use that. :)

Delete it, learn javascript, read and understand the newsgroup FAQ, and
start again.

<SCRIPT language="JavaS cript" type="text/javascript"> ^^^^^^^^^^^^^^^ ^^^^^^ not required<!--

Not needed. And if you want the first word to be indexed 0 or 1, use a
parameter rather than two routines, or supply a dummy zeroth entry.

function y2k(number) { return (number < 1000) ? number + 1900 : number; }
Not correct in all systems; see FAQ & sig. Function getFullYear is
generally available; and, if not, can be accurately emulated.

However, since your work is unlikely to be wanted for very long, you can
safely use 2000 + number%100 with a note about its range.

var months = new
makeArray('Jan uary','February ','March','Apri l','May','June' ,'July','August ','Se
p
tember','Octob er','November', 'December');
DO NOT let your posting agent break lines of code; do it yourself.
Posted code should be directly executable.

var months = ['January', 'February', 'March', 'April', 'May',' June',
'July', 'August', 'September', 'October', 'November', 'December']
var days = new
makeArray0('Su nday','Monday', 'Tuesday','Wedn esday','Thursda y','Friday','Sa turda

');
var days = ['Sunday', 'Monday', 'Tuesday',
'Wednesday', 'Thursday', 'Friday', 'Saturday']
var today = new Date();
var day = days[today.getDay()];
var date = today.getDate( ) + 15;
var month = today.getMonth( ) + 1;
var year = y2k(today.getYe ar());

document.write (months[month] +' ' + date + ', ' + year);
Don't use FFF, or anything like it, on the WWW.

So you were, on the previous day, prepared to believe June 31st?

Yes, that's exactly what you asked for, and should have foreseen.

You need to increment the date object, not the day-of-month.

Ignore any response containing 864e5 or its equivalent; it will not be
reliable for all potential users. Consider
function LZ(x) { return (x<0||x>=10?"": "0") + x }

with (new Date()) {
setDate(getDate ()+15)
document.writel n(
getFullYear(), '-', LZ(getMonth()+1 ), '-', LZ(getDate()) ) }

Which section? 4.30 refers to the page server clock.

My view is that if the date/time matters to the page author's
organisation, then it can be applied to the submitted response after
receipt at the server end; but if otherwise then it's up to the end user
to have his clock set as he wishes.

<FAQENTRY> FAQ 4.17 is in error in the text; the current date is not
unique. The code rightly uses the current GMT/UTC date/time, which is
(near enough) unique (the clock may be corrected backwards [but no
concern for the end of Summer Time]). Also, an "of" should be an "or".

FAQ 4.31, "everytime" -> "every time"

Section 3.2 has "Manipulati ng times, dates and the lastModified date
and time in javascript:-" followed by a link to your pages, where
there is a section "Some date troubles".

I was highlighting that using the client PC solely to determine the
date or time is not sensible. If the intention is to advise an
approximate delivery time or similar, it may be best to use dates and
times based on some accurate datum convenient to the OP, rather than
the client, then suggest what the equivalent *might* be at the client
location based on the client system date/time and tell the user that
that is how they were calculated.

Maybe the following script might be of use for you:

var fst = "+15d";
var dte = new Date();
var plusMinus = fst.match(/[+-]\d+[smhdy]/gi);
if (plusMinus) {
var vorz, shrt, val;
var multiplier = {"S":1,"M":60," H":3600,"d":864 00};
for (var i=0; i<plusMinus.len gth; i++) {
vorz = plusMinus[i].charAt(0) == "+" ? 1 : -1;
shrt = plusMinus[i].charAt(plusMin us[i].length-1);
val = vorz*Number(plu sMinus[i].substring(1,pl usMinus[i].length-1));
if (shrt == "m")
dte.setMonth(dt e.getMonth() + val);
else if (shrt.toLowerCa se() == "y")
dte.setFullYear (dte.getFullYea r() + val);
else if (multiplier[shrt])
dte.setTime(dte .getTime() + (val*multiplier[shrt]*1000));
}
}
alert(dte);

You may now add or substract seconds, minutes, hours, days, months or
years to your Date object (dte).

Use "+5S" for fst to add 5 seconds, use "-10d" to substract 10 days, use
"-2H" to substract 2 hours etc.
S = Seconds
M = Minutes
H = Hours
d = Days
m = Months
y = Years

Why so? It seems to be a rather ubiquitous idiom, and in any case how
else would one hide script from user agents that can't or won't
execute it?
