Here is a date validation through JavaScript that will give an alert message if you try to give a date less than today. It will always take the future date.
Below is the full HTML code:
<head runat="server">
<script language="javascript" type="text/javascript">
function validateDate() {
var expDate = document.getElementById('txtDate').value;
var date = expDate.substring(0, 2);
var month = expDate.substring(3, 5);
var year = expDate.substring(6, 10);
var myDate = new Date(year, month - 1, date);
var today = new Date();
if (myDate > today) {
}
else {
alert('Please enter a date greater than today !');
return false;
}
}
</script>
