How to view particular page of an pdf using HTML i

问题:

I would like to open a pdf file and show particular page when I press on a button

What I have tried inside an onclick listener is :

$("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>")

The problem is , it seems it can not ref to and just show the page 1, also , the size of pdf is not zoom as expected. e.g. the div is the exact size but the content is not. e.g. If I specific size = w:1000, h:2000, the background : w:1000,h:2000 , but the content may be w:800,h:1500.

How can I fix the problems ? thanks

If you know the page number to go to, and your PDF plugin is the one which comes with Adobe Acrobat Reader, you could do this:

largePdf.setCurrentPage(n);

The API is described here.

Below is a short list of APIs obtained with OleView on AcroPdf.dll (the plugin, "C:\Program Files (x86)\Common Files\Adobe\Acrobat\ActiveX\AcroPDF.dll" on my PC). It doesn't look like there is a way to find the total number of pages though.
