<div class="content wysiwyg-content">
I have a content div on a web page that allows users to jump to any point on the current page. &nbsp;These documents are pretty long and so the content div moves up and down to stay on screen with use of scrollTop().<br />
<br />
However, as these documents become larger, the content div is becoming larger than the viewport and as it lines up with the top of the page, it is sometimes impossible to get to the bottom of the content div.<br />
<br />
I have come up with a solution that requires me to know what direction the viewport is scrolling in. &nbsp;Can this be done? &nbsp;If I can find the scrolltop() value on scroll start and scrol end I could work out the direction so this may also be an option<br />
<br />
Many Thanks<br />

Detect scroll direction using jQeury

jQuery (Core) is a cross-browser JavaScript library that provides abstractions for common client-side tasks such as Document Object Model (DOM) traversal, DOM manipulation, event handling, animation and Ajax. jQuery also provides a platform to create plugins that extend jQuery's capabilities beyond those already provided by the library.

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
