需要将来自IntialFileList的自定义元数据值设置为dom/html

Question

我正在使用InitalFileList加载上一次会话中的文件。我上传的文件将有额外的s3元数据值，我需要显示一部分InitialFileList。在服务器端，我向jason对象添加了额外的元数据，我可以在控制台输出(响应)中看到它。

我的问题是..。如何将新的元数据/属性(qq-编辑标题是我的模板中的输入字段)设置为HTML显示。我在下面的回调中没有看到任何参数来获得dom上的句柄。任何帮助都是非常感谢的。

onSessionRequestComplete(response, success, xhrOrXdr) {
 //
}

我的HTML模板：

如果您的onSessionRequestComplete回调处理程序，您可以：

1. 迭代这些条目。
2. 使用API方法将每个条目映射到一个精细的Uploader文件ID。
3. 使用API方法获取DOM中每个容器元素的句柄。
4. 选择标题输入并使用所需的值更新它。

例如：

onSessionRequestComplete: function(response, success) {
   if (success) {
      var uploader = this
      response.forEach(function(item) {
         var id = uploader.getUploads({uuid: item.uuid}).id
         var fileEl = uploader.getItemByFileId(id)
         fileEl.querySelector('.qq-edit-caption').value = item.caption
      })
   }
}
