Hi,

the APIs GlideDate and GlideDateTime are usable only on server side.

I suggest you create an script include and checks and retrieves the value using a GlideAjax.

Please consider that creating a function in the script includes ( isInThePast( date ) ), then you can recall it in every script, both client and server, making the code easier to maintain.

Try also to look at this.

Please mark this as "Correct Answer" if I have given you a sufficient answer to your question.

Best Regards,

You can use following script in onChange client script for date validation. No need to call script include.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

if (isLoading || newValue === '') {
return;
}

var now = new Date();
now = formatDate(now, g_user_date_time_format);
now = getDateFromFormat(now, g_user_date_time_format);
var X = g_form.getValue('review_date'); //Review date is field on the form.

X = getDateFromFormat(X, g_user_date_time_format);
if (X < now) {
alert('Selected date is in the past.');
g_form.setValue('review_date', '');
}

return false;
}

Hi,

It is working fine , successfully restricting past date and as well is it possible to allow today date too..

because it is restricting Today date, 

it should allow today date and Future dates.....

Hi,

That is because it even count seconds also. I think you are selecting today date by clicking 'Go to today'. Once you select the today date just make 1 min after manually and try to submit form. In below script added alert. You can compare now and selected time. your selected datetime should be after now

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
	if (isLoading || newValue === '') {
		return;
	}
	
	
	var now = new Date();
	now = formatDate(now, g_user_date_time_format);
	
	alert("now.."+now+" "+"selected date.."+newValue);
	now = getDateFromFormat(now, g_user_date_time_format);
	
	var x = newValue;
	
	x= getDateFromFormat(x, g_user_date_time_format);
	
	if (x<now) {
		alert('Selected date is in the past.');
		g_form.setValue('review_date', '');
		return false;
	}
	
	
}
