title: Jump to page in PDF.js with javascript
body: <p>I'm trying to use PDF.js' viewer to display pdf files on a page.</p>
  
  <p>I've gotten everything working, but I would like to be able to 'jump to' a specific page in the pdf.  I know you can set the page with the url, but I would like to do this in javascript if it's possible.</p>
  
  <p>I have noticed that there is a PDFJS object in the global scope, and it seems that I should be able to get access to things like page setting there, but it's a rather massive object.  Anyone know how to do this?</p>
