Date Month display problem

[Jim]

I have been using the javascript below on a web page since last August to
show the "Site updated" month only minus a month, which has been very
successful, but January is showing a "undefined 2004" message.
Help much appreciated
Jim

<<<var m=new Array(13);var n=new Date()

m[1]="Site updated January";m[2]="Site updated February";m[3]="Site updated
March";m[4]="Site updated April";m[5]="Site updated May";m[6]="Site updated
June";
m[7]="Site updated July";m[8]="Site updated August";m[9]="Site updated
September";m[10]="Site updated October";m[11]="Site updated
November";m[12]="Site updated December"
document.write( m[n.getMonth()+0]+" "+n.getFullYear ())>>>

Hi Lasse
I like your recommended code but I can't get it to display at all.
I am very new to java and may well be overlooking
something simple.
Regards
Jim

In making the users think you update the page frequently? :)

but January is showing a "undefined 2004" message.

<<<var m=new Array(13);var n=new Date()

m[1]="Site updated January";m[2]="Site updated February";m[3]="Site updated March";m[4]="Site updated April";m[5]="Site updated May";m[6]="Site updated June";
m[7]="Site updated July";m[8]="Site updated August";m[9]="Site updated
September";m[10]="Site updated October";m[11]="Site updated
November";m[12]="Site updated December"
document.write( m[n.getMonth()+0]+" "+n.getFullYear ())>>>

getMonth returns the month number starting with 0 for January and ending

with

11 for December. Your table has 1=>January, so it gives the previous

month.

That means that you can change
m[12]="Site updated December"
to
m[0]="Site updated December"
and it will work for the month. The year from getFullYear is the current
one, so you will get December 2004 if that is all you do.
I recommend the following instead:
---
var monthName = [
"January","Febr uary","March"," April","May","J une","July",
"August","Septe mber","October" ,"November","De cember"];
var now = new Date();
now.setDate(1);
now.setMonth(no w.getMonth()-1);
document.write( "Site updated ",
monthName(now.g etMonth()),
" ",now.getFullYe ar());
---
We set the date back by one month, so the getMonth and getFullYear
refer to the same date. Setting the month to -1 will give December
of the previous year.

I set the date to the 1st to avoid problems when changing month.
Otherwise, setting the month back by one on the 31th of March would
give the 31th of February, which is normalized to give the 3rd of
March.

There is a bug in the code, so no wonder it's not working. Here
is a fixed version:

<script type="text/javascript">
var monthName = [
"January","Febr uary","March"," April","May","J une","July",
"August","Septe mber","October" ,"November","De cember"];
var now = new Date();
now.setMonth(no w.getMonth()-1,1);
document.write( "Site updated ",
monthName[now.getMonth()],
" ",now.getFullYe ar());
</script>

How about this instead?

var m = new Array(11);

Why "11". You create an array with 11 empty slots, [...]

Or an array with 1 non-empty slot containing a literal 11.
Depends on the ECMAScript implementation, so array literals
are the better way if the first element yields `true' for
!isNaN(...).
