Dato validering

Og jeg gi\'r gerne 50 point hvis den også tager højde for dato-formatet...

skal der også være ur med?

Jeg ved ikke om du kan bruge denne her;

<html>
<head>
<title>dato mm.</title>
</head>
<body onload=\"goforit()\">
<script>

var dayarray=new Array(\"Søndag\",\"Mandag\",\"Tirsdag\",\"Onsdag\",\"Torsdag\",\"Fredag\",\"Lørdag\")
var montharray=new Array(\"Januar\",\"Februar\",\"Marts\",\"April\",\"Maj\",\"Juni\",\"Juli\",\"August\",\"September\",\"Oktober\",\"November\",\"December\")

function getthedate(){
var mydate=new Date()
var year=mydate.getYear()
if (year < 1000)
year+=1900
var day=mydate.getDay()
var month=mydate.getMonth()
var daym=mydate.getDate()
if (daym<10)
daym=\"0\"+daym
var hours=mydate.getHours()
var minutes=mydate.getMinutes()
var seconds=mydate.getSeconds()
}
if (hours==0)
hours=24
if (minutes<=9)
minutes=\"0\"+minutes
if (seconds<=9)
seconds=\"0\"+seconds
var cdate=\"<small><font color=\'FFFFFF\' face=\'Arial\'><b>\"+dayarray[day]+\" d.\"+daym+\" \"+montharray[month]+\" \"+year+\" \"+hours+\":\"+minutes+\":\"+seconds+\" \"+dn\"</b></font></small>\"
if (document.all)
document.all.clock.innerHTML=cdate
else
document.write(cdate)
}
if (!document.all)
getthedate()
function goforit(){
if (document.all)
setInterval(\"getthedate()\",1000)
}

</script>
<span id=\"clock\"></span>
</body>
</html>

</tunoxw>

næh... det..

Se den her ser ud til at gøre jobbet:

<script language=\"JavaScript\">

function isDate( dateIn ) {
       
    var inDate = dateIn;
    var inDate2;
    var sDate;
    var chkDate;
    var cmpDate;

    var valid = true;

    if ( dateIn.length > 0 ) {

        if ( inDate.indexOf( \"-\" ) != -1 ) {
            sDate = inDate.split( \"-\" );
        } else {
            sDate = inDate.split( \"/\" );
        }

        chkDate = new Date( Date.parse( inDate ));
        if (( sDate[ 2 ] < 100 ) && ( sDate[ 2 ] >= 0 ))
            sDate[ 2 ] = 19 + sDate[ 2 ];
       
        cmpDate = ( chkDate.getMonth() + 1 ) + \"/\" +
                  ( chkDate.getDate()      ) + \"/\" +
                  ( chkDate.getFullYear()  );
        inDate2 = ( Math.abs( sDate[0] )) + \"/\" +
                  ( Math.abs( sDate[1] )) + \"/\" +
                  ( Math.abs( sDate[2] ));

        if (( inDate2 != cmpDate ) || ( cmpDate == \"NaN/NaN/NaN\" ))
            valid = false;

    } return valid;
}

function checkDate( dateIn ) {

    if ( !isDate( dateIn ))
        alert( \"You\'ve entered an invalid date or date format. Please use the MM/DD/YY or MM/DD/YYYY format.\" );
}

/* for test */
test = isDate (\'02/29/1999\');
alert (test);

</script>
