How do I jump to a specific location on a page?

Q: How do I jump to a specific location on a page? For example, I want to scroll to page 42 and 65% down the page!

A: You can add the following function to config.js:

var displayPageLocation = function(pageNumber, vpercent, hpercent) {

  var docViewer = readerControl.docViewer;

  if (docViewer.getCurrentPage() !== pageNumber) {

    docViewer.setCurrentPage(pageNumber);

  }

  var pageWidth = docViewer.getPageWidth(pageNumber - 1);

  var pageHeight = docViewer.getPageHeight(pageNumber - 1);

  var hpos = pageWidth * hpercent / 100;

  var vpos = pageHeight * vpercent / 100;

  var wPt = docViewer.getDisplayModeManager().getDisplayMode().pageToWindow({

    x: hpos > pageWidth ? 0 : Math.max(hpos, 0),

    y: vpos > pageHeight ? 0 : Math.max(vpos, 0)

  }, pageNumber - 1);

  var scrollView = $('#DocumentViewer');

  var scrollViewOffset = scrollView.offset();

  docViewer.scrollTo(wPt.x - scrollViewOffset.left, wPt.y - scrollViewOffset.top);

};

and you can call the function as follows:

displayPageLocation(42, 65, 0);
