HTML代码：

<div class="content-wrap">
   <div class="row">
      <script type="text/javascript">
         $(function() {
            $("div#myDropZone").dropzone({
                url : "/file-upload"
            });
         });
      </script>
      <div class="col-sm-12">
         <div class="nest" id="DropZoneClose">
            <div class="title-alt">
               <h6>DropZone</h6>
            </div>
            <div class="body-nest" id="DropZone">
               <div id="myDropZone" >
               </div>
               <button style="margin-top: 10px;" class="btn btn-info"
                  id="submit-all">Submit all files</button>
            </div>
         </div>
      </div>
   </div>
</div>

< div id =“myDropZone”>中的放置区域没有上诉！

最好的祝福 ：)
