Answer 1

您可以执行以下操作

$(document).on('change', '.selectnumber', function(e){

var selected =   $('.selectnumber').val();
$('.numberselected').text(selected);


//console.log(selected);
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select multiple data-style="bg-white rounded-pill px-4 py-3 shadow-sm"
                        class="selectnumber w-100 multiple searchable='Search here..'">
                        <option>23</option>
                        <option>17</option>
                        <option>14</option>
                        <option>11</option>
                        <option>9</option>
                    </select><!-- End -->
                    <div class="numberselected">
                         //numbers selected should display here. 
                    </div>
