是否可以将 select 下拉列表转换为 jQuery UI 日期选择器中的水平月份列表？

Question

我正在构建一个基于 jQuery UI Datepicker 的日历，可以选择一次显示 3 个月的日期范围。现在它看起来像屏幕截图：

所以我需要在此日历上方添加一个块，其中包含从当前月份开始的 12 个水平放置的月份。我想我需要将带有月份的默认 select 下拉列表转换为这个水平列表，但是由于我对 JavaScript 的经验不足，我什至无法借助互联网上的类似示例来使用它.

当您在此块中选择一个月份时，它应该将日历切换到 3 个选定的月份。希望您能给我一个解决方案建议。

这是我当前的代码：

$("#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);

我认为，Jquery-ui-calendar 中不会有默认选项，但您可以像下面的示例那样自定义，

这里我用 moment.js 设置顶部按钮，并根据之前选择的值单击增加或减少值。

见下面的工作代码：-

var monthNames = ["January", "February", "March", "April", "May", "June",
  "July", "August", "September", "October", "November", "December"
];

var firstMonth = moment(new Date()).month();

function setButton() {
  for (var i = 0; i < 12; i++) {
    var classs = "months active";
    if (i > 2) {
      classs = "months";
    }
    $("#list").append("<span class='" + classs + "'>" + monthNames[firstMonth++] + "</span>");
    if (firstMonth == 12) firstMonth = 0;
  }
}

setButton();

$(document).on("click", ".ui-datepicker-next", function() {
  $(".months").remove();
  firstMonth += 1;
  if (firstMonth > 11) {
    firstMonth = 0;
  }
  setButton();
});


$(document).on("click", ".ui-datepicker-prev", function() {
  $(".months").remove();

  firstMonth -= 1;
  if (firstMonth == -1) {
    firstMonth = 11;
  }
  setButton();
});

$(document).on("click", ".months:not(.active)", function() {
  $(".ui-datepicker-next").trigger('click');
})

$("#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');

希望对您有所帮助

当您选择月份时，使用 destroy() 在日期选择器上设置月份。

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

然后通过所选月份重新初始化日期选择器。

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())) {
                        return [true, 'ui-red-end', ''];
                    }
                    if (endDate && date && (endDate.getTime() === date.getTime())) {
                        return [true, 'ui-red-start', ''];
