html 调用 class 封装的 js，无反应

[TomeWong]

   <div class="uploader">
      <input type="file" id="file" multiple>
   </div>
   <script src="../src/index.js" type="module"></script>

import Queues from './widgets/queue.js'

class Uploader {
   constructor () {
      this.container = document.getElementById('file');

      this.queue = new Queues();

      this.pool = [];

      this.container.addEventListener('change', function() {
         var filesList = document.querySelector('#files').files;
            if(filesList.length==0){         //如果取消上传，则改文件的长度为 0         
               return;
            }else{  
               //如果有文件上传，这在这里面进行
               console.log(filesList);
               Queues.addFile(filesList);
            }
        })
    }
}

export default Uploader

运行后，选择后，js 中的代码没有触发，求原因

谢谢！！！

new Uploader()

[maichael]

你也没有实例化 Uploader 呀

[azcvcza]

在底下另起一行<script> var uploader = new Uploader() </script>
