问如何使用JQuery动态更改数据报警器并将其限制在不同的日期范围？

EN

<select class='form-control mr-2' id='idType' name='idType' placeholder='Select' required>
  <option>UserID</option>
  <option>UID</option>
  <option>All Records</option>";
</select>

$(document).ready(function() {

   var today = moment().format('YYYY-MM-DD');
   var pastMo = moment().subtract(2, 'M').format('YYYY-MM-DD');

   getDatePicker('2019-11-18', today);

   console.log(pastMo);

   $('#idType').change(function(){
     if($(this).val() == 'All Records'){
       $("#idSearch").prop("disabled", true);
       getDatePicker(pastMo, today);
     }
     else {
       $("#idSearch").prop("disabled", false);
       getDatePicker('2019-11-18', today);
     }
   });


function getDatePicker(min, today) {
  $('#start_datepicker').datepicker({uiLibrary: 'bootstrap4',format: 'yyyy-mm-dd', minDate: min, maxDate: today});
  $('#end_datepicker').datepicker({uiLibrary: 'bootstrap4',format: 'yyyy-mm-dd', minDate: min, maxDate: today});
}
