如何为 google chrome 内置 pdf 查看器指定参数？
我有一个像这样的嵌入标签：
<embed src="../../Content/PDF/StockReport.pdf#zoom=50" width="100%" height="100%">
#zoom=50 是一个参数，告诉 pdf 阅读器缩放到 50%。 这适用于除 google chrome 之外的所有浏览器，因为 chrome 有内置的 pdf 查看器。
如何将相同的参数传递给 google chrome 的 pdf 查看器？
I have an embed tag like this:
<embed src="../../Content/PDF/StockReport.pdf#zoom=50" width="100%" height="100%">
the #zoom=50 is a parameter that tells the pdf reader to zoom to 50%.
This works in all browsers but google chrome because chrome has a built in pdf viewer.
How can I pass this same parameter to google chrome's pdf viewer ?

在检查了各种 Chrome 错误报告后，我可以确认 Google Chrome 忽略了 Adobe PDF 查看器的默认功能。在回答这个问题时，还没有办法将参数（如缩放）传递给 Chrome PDF 查看器。
编辑
已在这方面取得进展铬团队。这项工作是参考 Acrobat SDK 和 RFC第3778章截至 2017 年 12 月，Chromium 添加了对
view、zoom、page、toolbar和nameddest的支持code>，后来又进入了 Chrome。After checking various chrome bug reports, I can confirm that Google Chrome ignores the default functionality of Adobe PDF viewer. At the time of this answer there is no way to pass parameters (like zoom) to the Chrome PDF viewer.
EDIT
Progress has been made on this by the Chromium team. The work was being done with reference to both the Acrobat SDK and RFC 3778. As of Dec 2017 Chromium added support for
view,zoom,page,toolbarandnameddestand later made it into Chrome.使用 iframe：

看来 Chrome 的更高版本现在可能就是答案。我成功地通过
object标记传递了zoom和page参数。案例：
示例：
It appears that a later release of Chrome may now be the answer. I had success passing
zoomandpageparameters through anobjecttag.Case:
Example:
请注意，不同浏览器实现新定义的方式存在一些模糊性。因此 RFC 已过时，并于 2017 年 3 月被 RFC 8118 取代
请注意，它不包括PDF 正文周围的 UI。例如，工具/导航栏是否应该打开和关闭，这取决于插件查看器用户界面。
关闭工具栏是没有意义的，因为它不会限制编辑、打印或保存，并且会让依赖第 508 条/辅助功能的用户变得更加困难。
然而，更有用的是
#navpanes=0不显示侧边栏。摘录显示：
它列出了以下片段，但并非所有片段都可能出现在每个浏览器或其 PDF 嵌入中。另请注意，稍后的条目可能会覆盖任何先前的操作。

#page=（适用于 Chrome 和大多数 Chromium 衍生产品，但 PDF“查看首选项” "在某些插件中也可能有效果）请注意，除非

view=, （是的，大多数？）viewrect=,,, （否，但看看 Zoom 如何通过设置比例和 top,left 进行类似操作？）search=（否）表单填写
fdf=（否）Note there is some ambiguity in the way different browsers implement the newer definitions. So the RFC was obsoleted and replaced in March 2017 by RFC 8118
Note it DOES NOT cover UI around the PDF body. Such as should a tool/navbar be flipped on and off which is down to the plug-in viewer User Interface.
Switching toolbar off, is pointless as it does not restrict edit, print or save and makes it harder for users that rely on section 508/Accessibility functions.
HOWEVER the more useful one is
#navpanes=0to not show the sidebar.Exract shows:
It lists the following fragments but not all may be present in each browser or its PDF embedment. Also beware a later entry may over-ride any earlier action.
