Jump to page in PDF.js with javascript

Question

I\'m trying to use PDF.js\' viewer to display pdf files on a page.

I\'ve gotten everything working, but I would like to be able to \'jump to\' a specific page in the pdf

You can set the page via JavaScript with:

var desiredPage = [the page you want];
PDFViewerApplication.page = desiredPage;

There is an event handler on this, and the UI will be adjusted accordingly. You may want to ensure this is not out of bounds:

function goToPage(desiredPage){
    var numPages = PDFViewerApplication.pagesCount;
    if((desiredPage > numPages) || (desiredPage < 1)){
        return;
    }
    PDFViewerApplication.page = desiredPage;
}
