JavaScript to control dd/mm/aaaa

[Paulo]

Hi, maybe you have used it on your web apps:

Do you know any function to control if the user typed some incorrect date
value on edit box? I need "dd/mm/aaaa" format check.

if types: 32/01/2009 don't submit because don't have 32 days
if types: 30/13/2009 don't submit because don't have month 13
if types: 29/02/2009 don't submit because don't have day 29 on February
and go on... ...

Thank you very much!

I would use the split function to separate the date parts, then create a new
string with the pieces arranged like a date, then use the isDate function to
see if its a valid date. (in VB)

However the OQ subject says javascript.

[And 'before submitting' means clietnside, being off topic.]

Try:

function goodDate(d) { // (d)d/(m)m/yyyy
d = d.split('/');
var t = new Date(d[2],d[1]-1,d[0]);
return t.getDate()==d[0] &&
t.getMonth()==d[1]-1 &&
t.getYear()==d[2];
};
