Scroll Automatically to the Bottom of the Page

Vanilla JS implementation:

element.scrollIntoView(false);

https://developer.mozilla.org/en-US/docs/Web/API/element.scrollIntoView


To scroll entire page to the bottom:

const scrollingElement = (document.scrollingElement || document.body);
scrollingElement.scrollTop = scrollingElement.scrollHeight;

You can view the demo here

To scroll a specific element to the bottom:

const scrollToBottom = (id) => {
    const element = document.getElementById(id);
    element.scrollTop = element.scrollHeight;
}

Here is the demo

And here's how it works:

Ref: scrollTop, scrollHeight, clientHeight

UPDATE: Latest versions of Chrome (61+) and Firefox does not support scrolling of body, see: https://dev.opera.com/articles/fixing-the-scrolltop-bug/


jQuery isn't necessary. Most of the top results I got from a Google search gave me this answer:

window.scrollTo(0, document.body.scrollHeight);

Where you have nested elements, the document might not scroll. In this case, you need to target the element that scrolls and use it's scroll height instead.

window.scrollTo(0, document.querySelector(".scrollingContainer").scrollHeight);

You can tie that to the onclick event of your question (i.e. <div onclick="ScrollToBottom()" ...).
