Question

What are the different ways you can control/read the Scrollbar in a web browser with JavaScript, apart from anchors? — Unless you can dynamically create anchors and tell the browser to scroll down to that.

Answer 1

To scroll by an arbitrary amount:

//Parameters being the amount by which to scroll in pixels (horizontal and vertical)
window.scrollBy(50, 50);

To scroll to a certain point:

 window.scrollTo(0, 30);

To read current position:

 document.body.scrollLeft
 document.body.scrollTop
