How to change the font color of an element set with "customDayRenderer"

[AF3412]

Hello! How to change the color of an element set with "customDayRenderer"?

Is it possible to set colors without the "customDayRenderer" method, as well as "clickDay", without clicking the mouse, dynamically after the calendar is displayed?

I'm generating calendar with next code:

var weekendMillis = [ 1525035600000, 1525122000000, 1525208400000, 1525813200000, 1524949200000, 1523998800000 ];
$('#calendar').calendar({
            startYear: new Date().getFullYear(),
            weekStart: 1,

            customDayRenderer: function (element, date) {
                if (weekendMillis.includes(date.getTime())) {
                    $(element).css('font-weight', 'bold');
                    $(element).css('color', 'red');
                }
            },
            clickDay: function(e) {
                var time = (e.date.getTime());

                if (!weekendMillis.includes(time)) {
                    weekendMillis.push(time);
                    $(e.element).css('font-weight', 'bold');
                    $(e.element).css('color', 'red');
                } else {
                    weekendMillis.splice(weekendMillis.indexOf(time), 1);
                    $(e.element).css('font-weight', 'normal');
                    $(e.element).css('color', 'grey');
                }

            },
        });

Ok, i'm do it :)

1. Add new style: .calendar-weekend-day { font-weight: bold; color: red; }

2. Create code like:

   $('#calendar').calendar({ startYear: new Date().getFullYear(), language: 'ru', weekStart: 1, customDayRenderer: function (element, date) { if (weekendMill.includes(date.getTime())) { $(element).addClass("calendar-weekend-day"); } }, clickDay: function (e) { let time = (e.date.getTime()); if (weekendMill.includes(time)) { weekendMill.splice(weekendMill.indexOf(time), 1); $(e.element).children(".day-content").removeClass("calendar-weekend-day");

       } else {
           weekendMill.push(time);
           $(e.element).children(".day-content").addClass("calendar-weekend-day");
   
       }
   },

   }); }
