I tried to embed a PDF document in a web page and found that I could never get the exact height of the PDF document, so a scroll bar appeared.
<embed id="pdf" width="100%" height="1000px" name="plugin" id="plugin" src="http://localhost:8080/static/assets/%E7%AC%AC%E5%8D%81%E4%B8%80%E5%B1%8A%E5%85%A8%E5%9B%BD%E9%85%B6%E5%AD%A6%E5%AD%A6%E6%9C%AF%E8%AE%A8%E8%AE%BA%E4%BC%9A%E6%9A%A8%E9%82%B9%E6%89%BF%E9%B2%81%E8%AF%9E%E8%BE%B090%E5%91%A8%E5%B9%B4%E7%BA%AA%E5%BF%B5%E4%BC%9A%EF%BC%88%E7%AC%AC%E4%B8%80%E8%BD%AE%E9%80%9A%E7%9F%A5%EF%BC%89.pdf" type="application/pdf" internalinstanceid="13">try to get the element, where either clientHeight or scrollHeight is the height of its viewport.
has also tried to embed an iframe, directly, but still can"t get the actual height inside it, so is there any way to get the actual height of the embed?
