你可以试试这个。我不确定。但你可以试试。

 TINY.box.show({url: "your url", post: "mainid=" + varMainId + "&subid=" + yourID);

Answer 2

您可以使用PDFObject。这需要Javascript。您也可以使用Object标签如下

<object data="yourfile.pdf" type="application/pdf" width="100%" height="100%">
  <p>Alternative text - include a link <a href="yourfile.pdf">yourfile</a></p>
</object>
