如何在浏览器中使用 HTML 查看 pdf 的特定页面？

Question

我想打开一个 pdf 文件并在按下按钮时显示特定页面

我在 onclick 监听器中尝试的是：

$("body").prepend("<object id='largePdf' data= '" + sourceFolder + "MyNews/2013/08/16/0/0/A/Content/1/A_ALL.pdf#page=1' type='application/pdf' width='1861' height='3061'>alt : <a href= '" + sourceFolder + "MyNews/2013/08/16/0/0/A/Content/1/A_ALL.pdf#page=1'>pg001.pdf</a></object>")

问题是，它似乎无法引用并仅显示第 1 页，而且 pdf 的大小也没有按预期缩放。例如div 是确切的大小，但内容不是。例如如果我具体size = w:1000,h:2000，背景：w:1000,h:2000，但内容可能是w:800,h:1500。

怎么可能 我解决问题？谢谢

如果您知道要访问的页码，并且您的 PDF 插件是 Adob​​e Acrobat Reader 附带的插件，您可以这样做：

largePdf.setCurrentPage(n);

API 描述为here.

下面是在 AcroPdf.dll 上使用 OleView 获得的 API 的简短列表（插件，“C:\Program Files (x86)\Common Files\Adobe\Acrobat\ActiveX\AcroPDF.dll”在我的 PC 上） .不过看起来好像没有办法找到总页数。
