PDF.JS更改页面部分

Question

I want to customize the behaviour of previous and next buttons inside the PDF.JS Viewer. I've found that inside viewer.js there is:

document.getElementById('previous').addEventListener('click',
  function() {
    PDFView.page--;
});
document.getElementById('next').addEventListener('click',
  function() {
    PDFView.page++;
});

For example I would like that, by clicking on the next button, does not change the page but just scroll down about 10 lines.

I hope that someone could help me.

Thanks

You have made half your way to the destination. However, you need to check the

scrollIntoView = function pageViewScrollIntoView(dest){...}

the PDFView.page is responsible for the page, the scrollIntoView is responsible for the offset, which in this case what you are looking for.
