Dear scripters,
I am working on a HTML form in which a date must be entered of the form
'dd-mm-yyyy'. Now I'm looking for a script that, when the user switches to
another form field, changes e.g. 'ddmmyyyy' or 'dd-m-yy' to 'dd-mm-yyyy'.
I have searched the net using google, but only found validators that show
an error if an incorrect format is used. (and I can't write one on my own)
Does someone has such a script for me?
much thanks in advance!

That can't be done, because the code can't guess whether 1122005 is January 12
or November 2. That's why you have to ask the user to correct it.

Unless you only reformat the entry with dashes if it has a length of 8.
<html>
<head>
<title>ddmmyyyy .htm</title>
<script type="text/javascript">
function format(that) {
var what = that.value;
if (what.length != 8) return;
that.value = what.substr(0,2 ) + "-" + what.substr(2,2 ) + "-" +
what.substr(4);
}
</script>
</head>
<body>
<form>
<input type="text" name="dmy" size="10" maxlength="10"
value="01122005 " onblur="format( this)">
</form>
</body>
</html>

'ddmmyyyy' or 'dd-m-yy' to 'dd-mm-yyyy'.
Given these constraints and
the boundaries of the "current" century
it can be done.
function organize(x){
if (/^\d{8}$/.test(x))
x.value = x.replace(/(\d{2})(\d{2})( \d{4})/,'$1-$2-$3')
else if (/^\d{1,2}\d{1,2} \d{2}$/.test(x)) {
a = x.split('-')
x.value = two(a[0])+'-'+two(a[1])+
'-'+(+a[2]>30)?'19'+a[2]:'20'+a[2]
}
}
function two(x){

Instead of using a textbox, maybe you could try dynamic listboxes
instead. That way, when the month listbox is clicked, the appropriate
amount of days are filled in the days listbox.
This way, you wouldn't have to worry if they put in a bad character or
not.

"... e.g. 'ddmmyyyy' or 'dd-m-yy' to 'dd-mm-yyyy'." doesn't include
'd-mm-yyy';
therefore, '1122005' is November 2, 2005.
Unless the examples ("e.g.") were not definitive.

They are given by the OP.
Why improving on a reasonable request,
instead of showing the asked code?

Based on the suggested format, I make it 1 December 2005, or it
may be 11 February 2005.
Or does ddmmyyyy really mean mmddyyyy?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
