My PDF is 13 pages, but when I used hash: 0.page.13, it only jumped to page 10. I had to setTimeout and call the same function again:

Only needed to do that once per page load, then it seems to be synched properly. I am sure there is a more elegant solution:

var is_caught_up = false;
function pdf_go(page){
     $('pdf_frame').contentWindow.location.hash=':0.page.'+page;
     if (!is_caught_up){
         setTimeout('pdf_catchup('+page+')', 500);
     }
}

function pdf_catchup(page){
    $('pdf_frame').contentWindow.location.hash=':0.page.'+page;
     is_caught_up = true;
}
