jquery ui datepicker上的日期范围选择器 [英] Date range picker on jquery ui datepicker

问题描述

我使用jquery ui创建了一个日期范围选择器，您可以使用相同的内联日历来选择日期。

I created a date range picker using jquery ui where you can use the same inline calendar to make both of your date selections.

在这里查看我的小提琴： http://jsfiddle.net/kVsbq/4/

See my fiddle here: http://jsfiddle.net/kVsbq/4/

JS

$(".datepicker").datepicker({
    minDate: 0,
    numberOfMonths: [12, 1],
    beforeShowDay: function (date) {
        var date1 = $.datepicker.parseDate($.datepicker._defaults.dateFormat, $("#input1").val());
        var date2 = $.datepicker.parseDate($.datepicker._defaults.dateFormat, $("#input2").val());
        return [true, date1 && ((date.getTime() == date1.getTime()) || (date2 && date >= date1 && date <= date2)) ? "dp-highlight" : ""];
    },
    onSelect: function (dateText, inst) {
        var date1 = $.datepicker.parseDate($.datepicker._defaults.dateFormat, $("#input1").val());
        var date2 = $.datepicker.parseDate($.datepicker._defaults.dateFormat, $("#input2").val());
        if (!date1 || date2) {
            $("#input1").val(dateText);
            $("#input2").val("");
            $(this).datepicker();
        } else {
            $("#input2").val(dateText);
            $(this).datepicker();
        }
    }
});

我希望能做的是这样的范围选择器： http://jsfiddle.net/D3wLX/1/

What I want to be able to do is a range selector like this: http://jsfiddle.net/D3wLX/1/

如果您选择较早的日期然后，较早的日期自动成为范围中的第一个日期，并突出显示中间日期。现在，在我原来的jquery ui解决方案中，它只会将较早的日期放在第二个输入中，而不是突出显示两者之间的日期。

If you select an earlier date then the earlier date is automatically made the first date in the range and the middle dates are highlighted. Right now on my original jquery ui solution it will just put the earlier date in the second input and not highlight the dates in between.

很棒的教程

$.datepicker._defaults.onAfterUpdate = null;
var datepicker__updateDatepicker = $.datepicker._updateDatepicker;
$.datepicker._updateDatepicker = function( inst ) {
   datepicker__updateDatepicker.call( this, inst );
   var onAfterUpdate = this._get(inst, 'onAfterUpdate');
   if (onAfterUpdate)
      onAfterUpdate.apply((inst.input ? inst.input[0] : null),
         [(inst.input ? inst.input.val() : ''), inst]);
}
$(function() {
   var cur = -1, prv = -1;
   $('#jrange div')
      .datepicker({
            //numberOfMonths: 3,
            changeMonth: true,
            changeYear: true,
            showButtonPanel: true,
            beforeShowDay: function ( date ) {
                  return [true, ( (date.getTime() >= Math.min(prv, cur) && date.getTime() <= Math.max(prv, cur)) ? 'date-range-selected' : '')];
               },
            onSelect: function ( dateText, inst ) {
                  var d1, d2;
                  prv = cur;
                  cur = (new Date(inst.selectedYear, inst.selectedMonth, inst.selectedDay)).getTime();
                  if ( prv == -1 || prv == cur ) {
                     prv = cur;
                     $('#jrange input').val( dateText );
                  } else {
                     d1 = $.datepicker.formatDate( 'mm/dd/yy', new Date(Math.min(prv,cur)), {} );
                     d2 = $.datepicker.formatDate( 'mm/dd/yy', new Date(Math.max(prv,cur)), {} );
                     $('#jrange input').val( d1+' - '+d2 );
                  }
               },
            onChangeMonthYear: function ( year, month, inst ) {
                  //prv = cur = -1;
               },
            onAfterUpdate: function ( inst ) {
                  $('<button type="button" class="ui-datepicker-close ui-state-default ui-priority-primary ui-corner-all" data-handler="hide" data-event="click">Done</button>')
                     .appendTo($('#jrange div .ui-datepicker-buttonpane'))
                     .on('click', function () { $('#jrange div').hide(); });
               }
         })
      .position({
            my: 'left top',
            at: 'left bottom',
            of: $('#jrange input')
         })
      .hide();
   $('#jrange input').on('focus', function (e) {
         var v = this.value,
             d;
         try {
            if ( v.indexOf(' - ') > -1 ) {
               d = v.split(' - ');
               prv = $.datepicker.parseDate( 'mm/dd/yy', d[0] ).getTime();
               cur = $.datepicker.parseDate( 'mm/dd/yy', d[1] ).getTime();
            } else if ( v.length > 0 ) {
               prv = cur = $.datepicker.parseDate( 'mm/dd/yy', v ).getTime();
            }
         } catch ( e ) {
            cur = prv = -1;
         }
         if ( cur > -1 )
            $('#jrange div').datepicker('setDate', new Date(cur));
         $('#jrange div').datepicker('refresh').show();
      });
});

.wrapper {
