Scroll PDF using JavaScript

问题

I found a similar question Scroll PDF embedded in HTML but didn't see an answer. Does anyone have any suggestions for how to manipulate a PDF displayed within an iframe? Similar to the previous post link, I'm trying to scroll the PDF when the iframe doesn't have the focus (the host page does).

Thanks!

Actually there is an answer in the link You provided:

Hardly.

What you might be able to do is to put the iframe into a div with overflow: auto, and give the iframe a very large height value so the containing PDF is at full size. Make the surrounding div less tall than the iframe. When your buttons get clicked, scroll the surrounding div.

I haven't tested it so there may be some snag on the way, but this could work - and is probably the best you can do.

It's pretty easy. That's how you do it:

It depends on whether the iframe is "out-source", not from your server. Let's just say that it is out-source

CODE

<div id="iframeContainer" style="width: 800px; height: 600px; overflow: auto;">
   <iframe width="1800" height="6000" src="yourPDFfileSRC" scrolling="no">
   </iframe>
//You have to know exact width and height of PDF file
</div>

 

<script type="text/javascript">
$("document").ready(function()
{
  $("#iframeContainer").scrollTop(1400);
});
</script>

BONUS

You could animate it like that:

<script type="text/javascript">
    $("document").ready(function()
    {
      $("#iframeContainer").animate({scrollTop: 1400}, 500); //500 - time of animation
    });
</script>
