设置日期范围与pikaday datepicker

Question

我有一个预订表单，我只需要两个输入#checkin和#checkout，这就是为什么我用datepicker与daterange一切都会好的几乎有一件事是我怎么才能选择15天之间两个约会？

顺便说一下我使用Pikaday datepicker

$(document).ready(function() { 
 

 
    $('.flexdatalist').flexdatalist({ 
 
    minLength: 0, 
 
    searchContain: true, 
 
    }).on('select:flexdatalist', function() { 
 
    $('#checkin').trigger("click"); 
 
    }); 
 

 
    assignPicker = function(id, whenClosed) { 
 
    if (typeof whenClosed !== 'function') { 
 
     whenClosed = null; 
 
    } 
 

 
    return new Pikaday({ 
 
     numberOfMonths: 2, 
 
     field: document.getElementById(id), 
 
     format: "DD.MM.YYYY", 
 
     minDate: new Date(), 
 
     firstDay: 1, 
 
     maxDate: new Date(2020, 12, 31), 
 
     onSelect: function() { 
 
     e = this.getDate(); 
 
     }, 
 
     onSelect: whenClosed 
 
    }); 
 
    } 
 

 
    assignPicker('checkin', function() { 
 
    $('#checkout').trigger("click"); 
 
    }); 
 
    assignPicker('checkout', function() { 
 
    $('#select').trigger("click"); 
 
    }); 
 

 
});

body { 
 
      padding: 30px; 
 
     } 
 
     input, 
 
     select { 
 
      width: 100%; 
 
      padding: 10px; 
 
      border: 1px solid #ccc; 
 
     }

你可以保存到收银台选择器的参考，然后绑定到签拣货机的onSelect方法的功能并相应地调整结帐日期选择器。您可以（也可能应该）加载Moment.js以使日期计算更容易。 Pikaday（你正在使用）的format属性在没有它的情况下甚至不会工作。

$(document).ready(function() { 

    $('.flexdatalist').flexdatalist({ 
    minLength: 0, 
    searchContain: true, 
    }).on('select:flexdatalist', function() { 
    $('#checkin').trigger("click"); 
    }); 

    assignPicker = function(id, whenClosed) { 
    if (typeof whenClosed !== 'function') { 
     whenClosed = null; 
    } 

    return new Pikaday({ 
     numberOfMonths: 2, 
     field: document.getElementById(id), 
     format: "DD.MM.YYYY", 
     minDate: new Date(), 
     firstDay: 1, 
     maxDate: new Date(2020, 12, 31), 
     onSelect: whenClosed 
    }); 
    } 

    var checkoutPicker = assignPicker('checkout', function() { 
    $('#select').trigger("click"); 
    }); 

    var checkinPicker = assignPicker('checkin', function() { 
    var maxDate = this.getMoment().add(15, 'days'); 
    checkoutPicker.setMaxDate(maxDate.toDate()); 
    checkoutPicker.setMinDate(this.getDate()); // min date of checkout = checkin 
    checkoutPicker.setDate(null); 
    $('#checkout').trigger("click"); // trigger checkout picker 
    }); 

});
