2. 在需要下拉框的html或者ftl文件中引入上述文件

<link href="/html/css/common/select2.min.css" rel="stylesheet"/>
<script src="/html/js/common/select2.min.js"></script>

3. 繼續在html或者ftl文件中加入一段script代碼， 其中course指的是下拉框的id

<script type="text/javascript">
    $(document).ready(function () {
        $('#course').select2();
    });

</script>

　這是選擇下拉框的html寫法：

 <div class="col-sm-4">
      <select class="form-control" id="course"> 

      </select>
 </div>

結果如下所示：下拉框返回的結果可通過服務端ajax返回
