How to specify parameters to google chrome adobe pdf viewer?

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 chr开发者_如何转开发ome's pdf viewer ?

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, toolbar and nameddest and later made it into Chrome.

Use iframe:

1. It works in Mozilla
2. It works in Chrome
3. No Javascript needed

Example:

<div id="mypdf">
<iframe src="/cennik.pdf#zoom=65" style="width: 100%; height: 800px;" frameborder="0" scrolling="no">
        <p>Your web browser doesn't support iframes.</p>
   </iframe>
</div>

It appears that a later release of Chrome may now be the answer. I had success passing zoom and page parameters through an object tag.

Case:

• Set zoom to 200%
• Set page to 2

Example:

<object data="https://your.url/docs/123.pdf#zoom=200&page=2" 
        type="application/pdf" 
        width="100%" 
        height="100%"> 
</object>
