Okay here it comes.

This is the main script, ive put it in a html page to illustrate how
it works :

-------------------------------------------------------------------------------

<html>
<head>
<script type="text/javascript">
function addRow(id){

var index = document.form1. hidden.value;
var tbody = document.getEle mentById(id).ge tElementsByTagN ame("TBODY")[0];
var row = document.create Element("TR");
row.setAttribut e("id","row" + index);

//Clone this node
var targetNode = document.getEle mentById('SELEC T')
input1 = targetNode.clon eNode(true)
input1.setAttri bute("name","se lect" +index)

input2 = document.create Element("input" );
input2.setAttri bute("name","a" +index)
input2.setAttri bute("value","" )
input2.setAttri bute("type","te xt")
input2.setAttri bute("readOnly" ,"false")
input2.setAttri bute("size","32 ")

input3 = document.create Element("input" );
input3.setAttri bute("name","x" )
input3.setAttri bute("value","" )
input3.setAttri bute("type","te xt")
input3.setAttri bute("readOnly" ,"false")
input3.setAttri bute("size","8" )
input3.setAttri bute("maxlength ","10")

link.href="java script:

If dt_datetime is new Date(2003, 7, 31), Aug 31, then dt_next_month will
become October 1st.

And, of course, according to Fred Hoyle, "October the First is Too Late"
(a book title).

If, in incrementing/decrementing the Month, the Date needs to be set to
1<=D<=28, then do the latter first.

Then you have to test for that, which requires knowing the lengths of
months. I believe the Date object knows those better than me. :)

You can set the month first, check if it worked, and if not, set the
date back.

// "date" is the date we want to add a month to

var mth = date.getMonth() ;
date.setMonth(m th+1);
if (date.getMonth( ) != mth+1) { //overflow
date.setDate(0) ; // day before 1st
}

With this code, the 28th through 31th of January this year are all
sent to the 28th of February.

In Internet Explorer NAMEd form elements are not part of the document.forms[].elements[] collection. This can be
demonstrated very simply with:

<body onload="createI nput();alert(do cument.forms['myForm'].elements['abc'].value);">
<form name="myForm">
</form>
<script type="text/javascript">
function createInput() {
var input2 = document.create Element("input" );
// input2.setAttri bute("id", "abc");
input2.setAttri bute("name","ab c");
input2.setAttri bute("value","" );
input2.setAttri bute("type","te xt");
input2.setAttri bute("readOnly" ,"false");
input2.setAttri bute("size","32 ");

document.forms['myForm'].appendChild(in put2);
}
</script>
</body>

If you uncomment "input2.setAttr ibute("id", "abc")" then you can access the form element via either
document.forms[].elements['abc'] or document.getEle mentById('abc') in IE 5.5+, Mozilla and Opera 7.

I believe that you have misunderstood what I wrote.

To go from a random date to the 1st..28th of next month, one can always
go first to the 1st..28th of the current month, and incrementing the
month then cannot affect the date.

That is, of course, good for getting to the last of a month. Except at
the end of the year, when the != is false. One should check instead to
see whether the getDate() gives what it gave before or use (mth+1)%12.

<URL:http://www.merlyn.demo n.co.uk/js-date1.htm#MC>
<URL:http://www.merlyn.demo n.co.uk/js-date2.htm#incr>

IIRC, setDate(0) may fail to give the last of the previous month in
Macintosh Netscape 4 - does anyone know? See, using Mac NS4, the second
in Bug Tests under <URL:http://www.merlyn.demo n.co.uk/js-dates.htm#SDT>.

It seems I did. What I was trying to hit, was the same date in the
next month, or the last day of the next month if that date doesn't
exist.

That will work.

What makes Date objects so much fun is, that when changing it from
one arbitrary date to another, using setMonth and setDate, then there
is no order that always work.

date first mth first
Feb 2nd => Jan 31th Jan 3rd Jan 31th
Jan 31th => Feb 2nd Feb 2nd Mar 2nd

It is safest to set either date or month to a safe value (e.g., 1 for
day or 0 for month) and then set the desired month and date in any
order.

DOH! There is always something :)

FAQ readers should know that trick, indirectly. It is a pity that the
routines which set Y M & D cannot have, as those which set h m & s have,
additional parameters to set lesser fields. Or rather, on checking the
old NS JS documentation and ECMA, it is a pity that it is not better
known that they do. Requires JS 1.3, which probably everyone has by
now?

Watch out also for the non-existence, within the EU, of one hour of
civil time on the last Sunday of March, at 01:00 GMT (possibly UTC in
some countries).
