Scroll Automatically to the Bottom of the Page

Question

Consider I have a list of questions. When I click on the first question, it should automatically take me to the bottom of the page.

For a matter of fact, I do know

Answer 1

Late to the party, but here's some simple javascript-only code to scroll any element to the bottom:

function scrollToBottom(e) {
  e.scrollTop = e.scrollHeight - e.getBoundingClientRect().height;
}

Answer 2

one liner to smooth scroll to the bottom

window.scrollTo({ left: 0, top: document.body.scrollHeight, behavior: "smooth" });

To scroll up simply set top to 0

Answer 3

Below should be the cross browser solution. It has been tested on Chrome, Firefox, Safari and IE11

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

window.scrollTo(0,document.body.scrollHeight); doesn't work on Firefox, at least for Firefox 37.0.2

Answer 4

Sometimes the page extends on scroll to buttom (for example in social networks), to scroll down to the end (ultimate buttom of the page) I use this script:

var scrollInterval = setInterval(function() { 
    document.documentElement.scrollTop = document.documentElement.scrollHeight;
}, 50);

And if you are in browser's javascript console, it might be useful to be able to stop the scrolling, so add:

var stopScroll = function() { clearInterval(scrollInterval); };

And then use stopScroll();.

If you need to scroll to particular element, use:

var element = document.querySelector(".element-selector");
element.scrollIntoView();

Or universal script for autoscrolling to specific element (or stop page scrolling interval):

var notChangedStepsCount = 0;
var scrollInterval = setInterval(function() {
    var element = document.querySelector(".element-selector");
    if (element) { 
        // element found
        clearInterval(scrollInterval);
        element.scrollIntoView();
    } else if((document.documentElement.scrollTop + window.innerHeight) != document.documentElement.scrollHeight) { 
        // no element -> scrolling
        notChangedStepsCount = 0;
        document.documentElement.scrollTop = document.documentElement.scrollHeight;
    } else if (notChangedStepsCount > 20) { 
        // no more space to scroll
        clearInterval(scrollInterval);
    } else {
        // waiting for possible extension (autoload) of the page
        notChangedStepsCount++;
    }
}, 50);

A simple way if you want to scroll down specific element

Call this function whenever you want to scroll down.

function scrollDown() {
 document.getElementById('scroll').scrollTop =  document.getElementById('scroll').scrollHeight
}

ul{
 height: 100px;
 width: 200px;
 overflow-y: scroll;
 border: 1px solid #000;
}

<ul id='scroll'>
<li>Top Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Something Here</li>
<li>Bottom Here</li>
<li style="color: red">Bottom Here</li>
</ul>

<br />

<button onclick='scrollDown()'>Scroll Down</button>

Vanilla JS implementation:

element.scrollIntoView(false);
