如何在jQuery的日历中显示具有默认选定值的数据

Question

他试图显示一些具有默认选定值但未显示的数据，即默认情况下已选择日历日，而我想显示一些数据但未显示日历{{3 }}

这是完整的html代码：

最初是代码：

  (function ($) {

  $.fn.calendar = function (opts) {
    var options = $.extend({
        color: '#308B22',
        months: ['Januar', 'Februar', 'März', 'April', 'Mai', 'Juni', 'Juli', 'August', 'September', 'Oktober', 'November', 'Dezember'],
        days: ['Mo', 'Di', 'Mi', 'Do', 'Fr', 'Sa', 'So'],
        onSelect: function (event) {}
    }, $.fn.calendar.defaults, opts);

    return this.each(function () {
        var currentYear, currentMonth, currentDay, currentCalendar;

        initCalendar($(this), options);
    });
  };

function initCalendar(wrapper, options) {
    var color = options.color; 

    wrapper.addClass('calendar').empty();

    var header = $('<header>').appendTo(wrapper);
    header.addClass('calendar-header');
    header.css({
        background: color,
        color: createContrast(color)
    });

    var buttonLeft = $('<span>').appendTo(header);
    buttonLeft.addClass('button').addClass('left');
    buttonLeft.html(' &lang; ');
    buttonLeft.bind('click', function () { currentCalendar = $(this).parents('.calendar'); selectMonth(false, options); });
    buttonLeft.bind('mouseover', function () { $(this).css('background', createAccent(color, -20)); });
    buttonLeft.bind('mouseout', function () { $(this).css('background', color); });

    var headerLabel = $('<span>').appendTo(header);
    headerLabel.addClass('header-label')
    headerLabel.html(' Month Year ');
    headerLabel.bind('click', function () { 
        currentCalendar = $(this).parents('.calendar');
        selectMonth(null, options, new Date().getMonth(), new Date().getFullYear());

        currentDay = new Date().getDate();
        triggerSelectEvent(options.onSelect);
    });

    var buttonRight = $('<span>').appendTo(header);
    buttonRight.addClass('button').addClass('right');
    buttonRight.html(' &rang; ');
    buttonRight.bind('click', function () { currentCalendar = $(this).parents('.calendar'); selectMonth(true, options); });
    buttonRight.bind('mouseover', function () { $(this).css('background', createAccent(color, -20)); });
    buttonRight.bind('mouseout', function () { $(this).css('background', color); });

    var dayNames = $('<table>').appendTo(wrapper);
    dayNames.append('<thead><th>' + options.days.join('</th><th>') + '</th></thead>');
    dayNames.css({
        width: '100%'
    });

    var calendarFrame = $('<div>').appendTo(wrapper);
    calendarFrame.addClass('calendar-frame');

    headerLabel.click();

    $('td').click(function(){
        $('td').show("Hello world!");
    });
    }

  function selectMonth(next, options, month, year) {
    var tmp = currentCalendar.find('.header-label').text().trim().split(' '), tmpYear = parseInt(tmp[1], 10);

    currentMonth = month || ((next) ? ((tmp[0] === options.months[options.months.length - 1]) ? 0 : options.months.indexOf(tmp[0]) + 1) : ((tmp[0] === options.months[0]) ? 11 : options.months.indexOf(tmp[0]) - 1));
    currentYear = year || ((next && currentMonth === 0) ? tmpYear + 1 : (!next && currentMonth === 11) ? tmpYear - 1 : tmpYear);

    var calendar = createCalendar(currentMonth, currentYear, options), frame = calendar.frame();

    currentCalendar.find('.calendar-frame').empty().append(frame);
    currentCalendar.find('.header-label').text(calendar.label);

    frame.on('click', 'td', function () {
        $('td').removeClass('selected');
        $(this).addClass('selected');

        currentDay = $(this).text();
        triggerSelectEvent(options.onSelect);
    });
 }  

    function createCalendar(month, year, options) {
    var currentDay = 1, daysLeft = true,
    startDay = new Date(year, month, currentDay).getDay() - 1,
    lastDays = [31, (((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0)) ? 29 : 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31], 
    calendar = [];

    var i = 0;
    while(daysLeft) {
        calendar[i] = [];

        for(var d = 0; d < 7; d++) {
            if(i == 0) {
                if(d == startDay) {
                    calendar[i][d] = currentDay++;
                    startDay++;
                }
            } else if(currentDay <= lastDays[month]) {
                calendar[i][d] = currentDay++;
            } else {
                calendar[i][d] = ''; 
                daysLeft = false;
            }

            if (currentDay > lastDays[month]) { 
                daysLeft = false; 
            } 
        }

        i++;
    }

    var frame = $('<table>').addClass('current');
    var frameBody = $('<tbody>').appendTo(frame);

    for(var j = 0; j < calendar.length; j++) {
        var frameRow = $('<tr id=tr-'+j+'>').appendTo(frameBody);
        id = j;
        $.each(calendar[j], function (index, item) {
            var frameItem = $('<td id=td-'+(id++)+'>').appendTo(frameRow);
            frameItem.text(item);
        });
    }

    $('td:empty', frame).addClass('disabled');
    if(currentMonth === new Date().getMonth()) { 
        $('td', frame).filter(function () { return $(this).text() === new Date().getDate().toString(); }).addClass('today'); 
    } 

    return { frame: function () { return frame.clone() }, label: options.months[month] + ' ' + year };
}

function triggerSelectEvent(event) {
    var date = new Date(currentYear, currentMonth, currentDay);

    var label = [];
    label[0] = (date.getDate() < 10) ? '0' + date.getDate() : date.getDate();
    label[1] = ((date.getMonth() + 1) < 10) ? '0' + (date.getMonth() + 1) : date.getMonth() + 1;
    label[2] = (date.getFullYear());

    if(event != undefined) {
        event({date: date, label: label.join('.')});
    }
}

function createContrast(color) {
    if(color.length < 5) {
        color += color.slice(1);
    }

    return (color.replace('#','0x')) > (0xffffff) ? '#222' : '#fff';
}

function createAccent(color, percent) {
    var num = parseInt(color.slice(1),16), amt = Math.round(2.55 * percent), 
    R = (num >> 16) + amt, G = (num >> 8 & 0x00FF) + amt, B = (num & 0x0000FF) + amt;
    return '#' + (0x1000000 + (R < 255 ? R < 1 ? 0 : R : 255) * 0x10000 + (G 
  < 255 ? G < 1 ? 0 : G : 255) * 0x100 + (B < 255 ? B < 1 ? 0 : B : 255)).toString(16).slice(1);
    }

html：

    <section style="max-width:400px;margin:150px auto;">

        <h1>Select Date</h1>
        <div id="pnlEventCalendar" style="width:100%;"></div>
        <p>selected date: <b><span id="lblEventCalendar">[date]</span></b> 
  </p>
        <script>
        $(function () {
            $('#pnlEventCalendar').calendar({months: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
                days: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'],onSelect: function (event) {
                $('#lblEventCalendar').text(event.label+ "Hello world!");
            }});
        });
            </script>
        </section>
    </body>
   <script type="text/javascript">

  var _gaq = _gaq || [];
  _gaq.push(['_setAccount', 'UA-36251023-1']);
  _gaq.push(['_setDomainName', 'jqueryscript.net']);
  _gaq.push(['_trackPageview']);

  (function() {
    var ga = document.createElement('script'); ga.type = 'text/javascript'; 
ga.async = true;
ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 
'http://www') + '.google-analytics.com/ga.js';
 var s = document.getElementsByTagName('script')[0]; 
 s.parentNode.insertBefore(ga, s);
 })();

</script>

  }(jQuery));

但是它不起作用，我该怎么办？？？ 我只想显示默认日期的数据，该日期是拍摄https://ibb.co/dGh5C60

的当前日期
