如何为日期选择器创建日期范围日期间隔？

Question

我正在使用 Pikaday Plugin 并且我根据需要创建了预订表格，我认为它现在很好，除了一个问题。

有一个日期范围函数，我在两个输入日期之间设置了 15 天 if you click this link you will see

我有相同的表格，自动下一个焦点，但我无法在 15 天内应用我的日期范围功能我如何应用它我的代码如下

and by the way this is my auto next form link

function getMaxDate(element){
  if(element.id=='checkout')
    return new Date(new Date(element.parentNode.querySelector('#checkin').value).getTime()+(15*24*60*60*1000));
else
  return new Date(2020, 12, 31);
  }
function getMinDate(element){
  if(element.id=='checkout')
    return new Date(element.parentNode.querySelector('#checkin').value);
  else
  return new Date();
  }

Answer 1

您可以查看以下代码，了解我们如何在 15 天范围内验证日期。您试图在加载时验证结账日期，所以他无法获取签到日期，这就是它无法正常工作的原因。

$(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: getMaxDate(id),
      onSelect: function() {
        e = this.getDate();
      },
      onSelect: whenClosed
    });
  }

  assignPicker('checkin', function() {

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


});
function getMaxDate(id){
  if(id=='checkout')
    return new Date(new Date($('#checkin').val()).getTime()+(15*24*60*60*1000));
else
  return new Date(2020, 12, 31);
  }

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