How can I restrict a date field from allowing to enter future date?

Thank you,

Try this On Change Client Script for your date field that you want to check:

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

   if (isLoading || newValue === '') {

      return;

   }

            //current date

            var currentDateObj = new Date();

            var currentDateStr = formatDate(currentDateObj, g_user_date_format);

            var currentDateNum = getDateFromFormat(currentDateStr, g_user_date_format);

            var startDateNum = getDateFromFormat(newValue, g_user_date_format);

            if (startDateNum > currentDateNum) {

                        alert(“Date is in the future”);              

                        g_form.clearValue("your_date_field");

                        return false;

            }

}
