推荐答案

在Firefox页面中，使用<object data="...">显示带有扫描的PDF. 上载的文档"部分中有按钮可显示其他扫描.

In Firefox page uses <object data="..."> to display PDF with scan. There are buttons in section "Uploaded Documents" to display other scans.

此代码使用这些按钮来显示扫描结果，从<object>获取数据并将其保存在文件document-0.pdf，document-1.pdf等中.

This code uses these buttons to display scans, get data from <object> and save in files document-0.pdf, document-1.pdf, etc.

我使用的是您在回答上一个问题时看到的相同代码:

I use the same code you could see in my answer to your previous question:
