jquery - 如何在引导选择标签中获取价值

Question

这是我的代码，但我无法获取在 selectpicker 引导程序中选择的值。知道怎么做吗？

<select class="selectpicker form-group show-tick" id ="department"  data-live-search="true" data-width="100%" multiple title = "Select Restaurant/Store - ID" data-max-options="1">
             <?php
                    while ($rstorefrom = mysqli_fetch_array($resultstorefrom))
                    {
                        echo "<option value = " .$rstorefrom['department']. "data-tokens=" .$rstorefrom['department'].">" .$rstorefrom['department']. "</option>";

                        echo "<script>
                          $('#department').on('click',function() {
                          alert($(this).val());
                          console.log($(this).val());
                        </script>";
                    } 


              ?>
            </select>

您必须使用图书馆事件，如changed.bs.select获取更多信息；https://silviomoreto.github.io/bootstrap-select/options/

$("#department").on("changed.bs.select",function(){
  console.log($(this).val())
});

<select class="selectpicker form-group show-tick" id ="department"  data-live-search="true" data-width="100%" multiple title = "Select Restaurant/Store - ID" data-max-options="1">
  <option value="1">Pizza</option>
    <option value="2">More Pizza</option>
      <option value="3">Big Pizza</option>
             </select>
