How do I programmatically navigate document preview?

[warrenzhai1]

I'm developing a custom navigation to navigate to different pages of a PDF preview pane using JavaScript.  I can use Dojo to get the input control and change the value easily but firing the change event doesn't change the navigation page.  Do you know what's the best way for me to do this either using Alfresco.WebPreview or some other control?

i believe you can already link to specific pages in a preview in share/pdf.js and there is an aikau method for scrolling, see:

JSDoc: Module: alfresco/preview/PdfJs/PdfJs
