Is it possible to convert select dropdown into horizontal months list in jQuery UI Datepicker?


I'm building a calendar based on jQuery UI Datepicker with a possibility to choose date range with 3 months displayed at once. Now it looks like on screenshot: calendar

So I need to add a block above this calendar with 12 horizontally positioned months starting from current month. I think I need to convert default select dropdown with months to this horizontal list, but due to my little experience with JavaScript I wasn't able to even bring it to work with help of similar examples from internet.

months

When you choose a month in this block it should switch calendar to 3 chosen months. Hope you will be able to suggest me a solution.

Here is my current code:

$("#datepicker").datepicker({
numberOfMonths: 3,
showButtonPanel: false,
dateFormat: 'dd.mm.yy',
minDate: 0,
maxDate: new Date(new Date().getTime() +  365 * 24 * 60 * 60 * 1000),
beforeShowDay: function(date) {
	var startDate = $.datepicker.parseDate('dd.mm.yy', $('#start-date').val());
	var endDate = $.datepicker.parseDate('dd.mm.yy', $('#end-date').val());
	if (startDate && endDate && startDate - endDate) {
		if (endDate <= date && date <= startDate) {
			if (startDate && date && (startDate.getTime() === date.getTime())) {
				console.log('from end to start - backward - red-start ');
				return [true, 'ui-red-end', ''];
			}
			if (endDate && date && (endDate.getTime() === date.getTime())) {
				console.log('from end to start - backward - red-end ');
				return [true, 'ui-red-start', ''];
			}
			console.log('from end to start - backward');
			return [true, 'ui-state-selected-range', ''];
		}
	}
	if (startDate <= date && date <= endDate) {
		console.log('from start to end - forward');
		if (startDate && date && (endDate.getTime() === date.getTime())) {
			console.log('from start to end - forward - red-end');
			return [true, 'ui-red-end', ''];
		}
		if (endDate && date && (startDate.getTime() === date.getTime())) {
			console.log('from start to end - forward - red-start');
			return [true, 'ui-red-start', ''];
		}
	}
	if (startDate <= date && date <= endDate) {
		console.log('from start to end');
		return [true, 'ui-state-selected-range', ''];
	}
	return [true, '', ''];
},
onSelect: function(dateText, inst) {
	var startDate = $.datepicker.parseDate('dd.mm.yy', $('#start-date').val());
	var endDate = $.datepicker.parseDate('dd.mm.yy', $('#end-date').val());
		if (!startDate || endDate) {
			$('#start-date').val(dateText);
			$('.start-date-visible').text(dateText);
			$('#end-date').val('');
			$('.end-date-visible').text('');
			$(this).datepicker('option', dateText);
		} else {
			if (new Date(dateText) < startDate) {
				var sDate = $('#start-date').val();
				$('.start-date-visible').text(dateText);
				$('#start-date').val(dateText);
				$(this).datepicker('option', null);
				$('.end-date-visible').text(sDate);
				$('#end-date').val(sDate);

			} else {
				$('.end-date-visible').text(dateText);
				$('#end-date').val(dateText);

			}
		}
}
});

Solution

  • Hope this helps

    use destroy() to set month on datepicker when you choose a month.

    $("#datepicker").datepicker("destroy");

    Then reinitialize datepicker passing selected month.

    var today=new Date();
    var newDate;
    setCalender(today.getMonth());
    var today=$("#datepicker").datepicker("getDate");
    var todayMonth=today.getMonth();
    setMonth(todayMonth);
    clickMonth();
    function setCalender(defaultMonth){
    $("#datepicker").datepicker("destroy");
    if(today.getMonth()==defaultMonth){
    newDate=new Date(today.getFullYear(),today.getMonth(),today.getDate());
    }
    else if(today.getMonth()>defaultMonth){
    newDate=new Date(today.getFullYear()+1,defaultMonth,today.getDate());
    }
    else{
    newDate=new Date(today.getFullYear(),defaultMonth,today.getDate());
    }
    $("#datepicker").datepicker({
            numberOfMonths: 3,
            showButtonPanel: false,
            dateFormat: 'dd.mm.yy',
            defaultDate: newDate,
            minDate: 0,
            maxDate: new Date(new Date().getTime() + 365 * 24 * 60 * 60 * 1000),
            beforeShowDay: function(date) {
            var dates=new Date();
    
                var startDate = $.datepicker.parseDate('dd.mm.yy', $('#start-date').val());
                var endDate = $.datepicker.parseDate('dd.mm.yy', $('#end-date').val());
                if (startDate && endDate && startDate - endDate) {
                    if (endDate <= date && date <= startDate) {
                        if (startDate && date && (startDate.getTime() === date.getTime())) {
