Hi all...


Can anyone tell me how can i check that a string contains a date.


Thanks in advance...

Hi all...



<script language="JavaScript">
function validateDate(date) {
// NaN is never equal to itself.
if (Date.parse(date) != Date.parse(date))
document.write(date + ' - Invalid date<br>');
else
document.write(date + ' - Valid date<br>');
}


validateDate('hello world');
validateDate('29 January 1999');
validateDate('February 30 2000');
validateDate('Sat 8 2000 Jan');
</script>


Thanks...

<script language="JavaScript"><!--
function y2k(number) { return (number < 1000) ? number + 1900 : number; }

function isDate (day,month,year) {
// checks if date passed is valid
// will accept dates in following format:
// isDate(dd,mm,ccyy), or
// isDate(dd,mm) - which defaults to the current year, or
// isDate(dd) - which defaults to the current month and year.
// Note, if passed the month must be between 1 and 12, and the
// year in ccyy format.

var today = new Date();
year = ((!year) ? y2k(today.getYear()):year);
month = ((!month) ? today.getMonth():month-1);
if (!day) return false
var test = new Date(year,month,day);
if ( (y2k(test.getYear()) == year) &&
(month == test.getMonth()) &&
(day == test.getDate()) )
return true;
else
return false
}

if (isDate(31,2,1997))
document.write("Valid");
else
document.write("Invalid");
//--></script>
