无法在filepond中查看图像预览

Question

我正在尝试使用filepond上传一些图片。上传工作正常。我也想看看上传的图像预览。我已经尝试使用插件，但显然，我看不到任何变化。

{% block style %}
<link href="https://unpkg.com/filepond/dist/filepond.css" rel="stylesheet">
<link href="https://unpkg.com/filepond-plugin-image-preview/dist/filepond-plugin-image-preview.min.css" rel="stylesheet">
 {% endblock %}

以下是我的脚本

{% block scripts %}
</script>
<!-- FILE POND STUFF -->
<script src="https://unpkg.com/filepond-plugin-image-preview/dist/filepond-plugin-image-preview.js"></script>
<script src="https://unpkg.com/filepond/dist/filepond.js"></script>
<script>
FilePond.parse(document.body);
</script>
{% endblock %}

这是我的JS文件

$('#file_upload').change(function() {
    const inputElement = document.querySelector('input[type="file"]');

    FilePond.registerPlugin(FilePondPluginImagePreview);

    const pond = FilePond.create( inputElement, {
    allowMultiple: true,
    allowFileEncode: true,
  });

}

我的HTML代码

<input type="file" name='file' class='filepond' multiple  id='file_upload'/>

我不能确定是否有任何额外的步骤。

const inputElement = document.querySelector('#file_upload');

FilePond.registerPlugin(FilePondPluginImagePreview);

  const pond = FilePond.create( inputElement, {
    allowMultiple: true,
    allowFileEncode: true,
});

<link href="https://unpkg.com/filepond-plugin-image-preview@4.2.1/dist/filepond-plugin-image-preview.min.css" rel="stylesheet"/>
<link href="https://unpkg.com/filepond@4.4.10/dist/filepond.css" rel="stylesheet"/>
<script src="https://unpkg.com/filepond-plugin-image-preview@4.2.1/dist/filepond-plugin-image-preview.js"></script>
<script src="https://unpkg.com/filepond@4.4.10/dist/filepond.js"></script>

<input type="file" name='file' class='filepond' multiple  id='file_upload'/>

<script>
FilePond.parse(document.body);
</script>
