How to Scroll to the Bottom in JavaScript
The HTML Document Object Model (DOM) gives you substantial control over the structure and content of a Web page. The "scrollHeight" DOM property can be used to determine the total height of the body of the Web page, not just the visible portion. Combine this property with the "scrollTo" method of the "window" object to make a JavaScript function that instantly scrolls the user's browser window to the bottom of the page.
