Regular expression for date format- dd-mm-yyyy in Javascript

Question

I need a regular expression for date format: dd-mm-yyyy in Javascript.

Answer 1

$('#DOB').blur(function ()   {
var s = $('#DOB').val();   alert('Entered date is:' + s);
var parms = s.split(/[\.\-\/]/);
var yyyy = parseInt(parms[2], 10);

var d = new Date();
var n = d.getFullYear(); //alert('current year is :' + n);
if (yyyy > n || yyyy < 1900) {
    alert('Improper date format, Please enter dd/mm/yyyy format. (invalid year)');
}
var mm = parseInt(parms[1], 10); 
if (mm > 12 || mm < 0)
{
    alert('Improper date format, Please enter dd/mm/yyyy format. (invalid month');
}
var dd = parseInt(parms[0], 10);
if (dd > 31 || dd < 0)
{
    alert('Improper date format, Please enter dd/mm/yyyy format. (invalid day');
}

//var date = new Date(dd, mm - 1, yyyy, 12, 0, 0, 0);
//var ndate = (date.getMonth() + 1) && ddmm === date.getDate() &&  yyyy === date.getFullYear();
// alert('new date is:' + ndate);
});
