使用Bootstsrap Jquery在日期选择器中将下一个和上一个月替换为下一个和前一天

我有一个内联的jquery bootstrap datepicker，并且我想在今天尝试的这一天增加和减少：

// Html Code
<div id="datepicker"></div> 

// JS Code
$('#datepicker').datepicker({
    todayHighlight: true,
    language: 'en', 
 });
$('.btn-next').on("click", function () {
    var currentDate = $('#datepicker').datepicker('getDate');
    var selectedDate= new Date(currentDate);
    // Increase current day by +1
    selectedDate.setDate(selectedDate.getDate() + 1);
    $('#datepicker').datepicker('update',selectedDate);
});

$('.btn-prev').on("click", function () {
    var currentDate = $('#datepicker').datepicker('getDate');
    var selectedDate= new Date(currentDate);
    // Decrease current day by -1
    selectedDate.setDate(selectedDate.getDate() - 1);
    $('#datepicker').datepicker('update',selectedDate);
});

但这已经不起作用了，这个操作员的任何想法

你并不需要再次转换当日你从日期选择器仅获得+1或-1给它里面添加日期选择新的价值。

演示代码：

$('#datepicker').datepicker({
  todayHighlight: true,
  language: 'en',
});
$('.btn-next').on("click", function() {
  var currentDate = $('#datepicker').datepicker('getDate');
  currentDate.setDate(currentDate.getDate() + 1);
  $('#datepicker').datepicker('update', currentDate);
});

$('.btn-prev').on("click", function() {
  var currentDate = $('#datepicker').datepicker('getDate');
  currentDate.setDate(currentDate.getDate() - 1);
  $('#datepicker').datepicker('update', currentDate);
});
