我正在使用JQuery阻止一些日期，但下个月是可用的。一个用户可以点击今天+5，所有其他的都应该被禁用。我做错了什么？
<div id='datepicker' onchange="test(this)">
</div>
$('#datepicker').datepicker(
{
numberOfMonths: 2,
beforeShowDay: function (date) {
var hilight = [true, 'isActive'];
var today = new Date();
var blockdays = new Date();
// var startdayofmonth = new Date(today.getFullYear(), today.getMonth(), 1);
today.setDate(today.getDate() + 5);
blockdays.setDate(blockdays.getDate() + 12);
blockdays = moment(blockdays.toLocaleDateString(), 'MM.DD.YYYY').format('YYYY-DD-MM');
var blockendofmonth = new Date(today.getFullYear(), today.getMonth() + 1, 1);;
blockendofmonth = moment(blockendofmonth.toLocaleDateString(), 'MM.DD.YYYY').format('YYYY-DD-MM');
today = moment(today.toLocaleDateString(), 'MM.DD.YYYY').format('YYYY-DD-MM');
date = moment(date.toLocaleDateString(), 'MM.DD.YYYY').format('YYYY-DD-MM');
if (date < today) {
hilight = [false, ''];
}
else if (date >= blockdays) {
hilight = [false, ''];
}
return hilight;
}
}
);
比较yyyy-dd-mm格式的日期字符串会得到不正确的结果。'2021-10-04'<'2021-20-03'该值的计算结果为true，而这实际上是不正确的。比较日期字符串时，为了获得更好的结果，最好遵循yyyy-mm-dd:hh:mm:ss格式。下面的代码段签出。
null
$(document).ready(function () {
var allowDays = getAllowDays();
$('#datepicker').datepicker({
numberOfMonths: 2,
beforeShowDay: function (date) {
var hilight = [true, 'isActive'];
var start = allowDays[0];
var end = allowDays[1];
var currentDate = +moment(date).format('YYYYMMDD');
if (currentDate < start) {
hilight = [false, ''];
} else if (currentDate >= end) {
hilight = [false, ''];
}
return hilight;
}
});
});
function getAllowDays() {
var today = new Date();
var blockdays = new Date();
today.setDate(today.getDate() + 5);
blockdays.setDate(blockdays.getDate() + 12);
return [+moment(today).format('YYYYMMDD'), +moment(blockdays).format('YYYYMMDD')];
