动态更新日期选择器选项

Question

我使用以下代码从日期选择器中选择多个日期：

 jQuery("#m_dates")
        .datepicker({
          onSelect: function (dateText, inst) {
              $scope.addOrRemoveDate(dateText,$scope.multi_dates,'m');
          },
          beforeShowDay: function (date) { 
            var year = date.getFullYear();
            var month = $scope.padNumber(date.getMonth() + 1);
            var day = $scope.padNumber(date.getDate());
            // This depends on the datepicker's date format
            var dateString = year + "-" + month + "-" + day;
            var gotDate = jQuery.inArray(dateString, $scope.data.post.multi_dates);

            if (gotDate >= 0) {
             // Enable date so it can be deselected. Set style to be highlighted
                return [true, "state-highlight"];
            }

            // Dates not in the array are left enabled, but with no extra style
               return [true, ""];
          },
          changeMonth: true, changeYear: true, dateFormat: "yy-mm-dd",
                minDate: jQuery.datepicker.parseDate($scope.data.post.date_format,$scope.data.post.start_date),
                maxDate: jQuery.datepicker.parseDate($scope.data.post.date_format,$scope.data.post.end_date)
          });

在更改开始日期和结束日期字段时，我想更改上述日期选择器的minDate和maxDate选项。为此，我使用了以下代码：

    jQuery('#m_dates').datepicker("change", { 
           minDate: jQuery.datepicker.parseDate($scope.data.post.date_format,$scope.data.post.start_date) 
          });
    jQuery('#m_dates').datepicker('change', { 
           maxDate: jQuery.datepicker.parseDate($scope.data.post.date_format,$scope.data.post.end_date) 
          });
    jQuery('#m_dates').datepicker("refresh");

但是，只有点击日期选择器，上面的代码才会刷新日历日期。
