Scroll Automatically to the Bottom of the Page

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

How can I do this with jQuery?

Here's a fairly modern react/typescript-ish utility I am using:

export const scrollToBottom = () => {
  // Assume a react re-render may need to happen first
  setTimeout(() => {
    requestAnimationFrame(() => {
      window.scrollTo({
        top: document.documentElement.scrollHeight - window.innerHeight,
        left: 0,
        behavior: 'smooth',
      })
    })
  }, 3)
}

See browser support on smooth scrolling here: https://developer.mozilla.org/en-US/docs/Web/API/Window/scrollTo#browser_compatibility

This could probably be turned into a hook:

export const useScrollToBottomWhen = (condition: boolean) => {
  useEffect(() => {
    if (condition) {
      window.scrollTo({
        top: document.documentElement.scrollHeight - window.innerHeight,
        left: 0,
        behavior: 'smooth',
      })
    }
  }, [condition]);
}

using reac.js here is the working code

        //auto scroll to the bottom 
    useEffect(()=>{
      const chatHolder = document.getElementById('chats-wrapper')
       if(chatHolder) {
          chatHolder.scrollIntoView({behavior: "smooth"})
       }
  },[chats])

Maybe there is "autofocus" somewhere in your code

If there is an ID in any kind of tag at or nearby where you want to scroll to, then all it takes is one line of JavaScript making use of the scrollIntoView function. For example, let's say your element in question is a DIV with the ID "mydiv1"

<div id="mydiv1">[your contents]</div>

then you would run the JavaScript command

document.getElementById("mydiv1").scrollIntoView();

No JQuery is necessary at all. Hope this helps.

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 its scroll height instead.

nestedElement.scrollTo(0, nestedElement.scrollHeight);

Some additional sources you can take a look at:

I gave up with scrollto but instead tried anchor approach:

<a href="#target_id_at_bottom">scroll to the bottom</a>

Along with this CSS charm:

html,
body {
    scroll-behavior: smooth;
}

Have a nice day!

CSS-Only?!

An interesting CSS-only alternative:

display: flex; 
flex-direction: column-reverse;

  /* ...probably usually along with: */

overflow-y: scroll;  /* or hidden or auto */
height: 100px; /* or whatever */

It's not bullet-proof but I've found it helpful in several situations.

Documentation: flex, flex-direction, overflow-y

Demo:

var i=0, foo='Lorem Ipsum & foo in bar or blah ! on and'.split(' ');
setInterval(function(){demo.innerHTML+=foo[i++%foo.length]+' '},200)
#demo{ display:flex;
       flex-direction:column-reverse;
       overflow-y:scroll;
       width:150px; 
       height:150px;
       border:3px solid black; }
body{ font-family:arial,sans-serif; 
      font-size:15px; }
Autoscrolling demo:&#x1f43e;
<div id='demo'></div>

We can use ref and by getElementById for scrolling specific modal or page .

 const scrollToBottomModel = () => {
    const scrollingElement = document.getElementById("post-chat");
    scrollingElement.scrollTop = scrollingElement.scrollHeight;
  };

In the modal body you can call above function

 <Modal.Body
          className="show-grid"
          scrollable={true}
          style={{
            maxHeight: "calc(100vh - 210px)",
            overflowY: "auto",
            height: "590px",
          }}
          ref={input => scrollToBottomModel()}
          id="post-chat"
        >

will work this

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:

enter image description here

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/

Here is a method that worked for me:

Expected outcome:

  • No scroll animation
  • Loads at bottom of page on first load
  • Loads on bottom of page for all refreshes

Code:

<script>
    function scrollToBottom() {
        window.scrollTo(0, document.body.scrollHeight);
    }
    history.scrollRestoration = "manual";
    window.onload = scrollToBottom;
</script>

Why this may work over other methods:

Browsers such as Chrome have a built-in preset to remember where you were on the page, after refreshing. Just a window.onload doesn't work because your browser will automatically scroll you back to where you were before refreshing, AFTER you call a line such as:

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

That's why we need to add:

history.scrollRestoration = "manual";

before the window.onload to disable that built-in feature first.

Documentation for window.onload: https://developer.mozilla.org/en-US/docs/Web/API/GlobalEventHandlers/onload

A simple way if you want to scroll down to a 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>

I found a trick to make it happen.

Put an input type text at the bottom of the page and call a jquery focus on it whenever you need to go at the bottom.

Make it readonly and nice css to clear border and background.

I've had the same issue. For me at one point in time the div's elements were not loaded entirely and the scrollTop property was initialized with the current value of scrollHeight, which was not the correct end value of scrollHeight.

My project is in Angular 8 and what I did was:

  1. I used viewchild in order to obtain the element in my .ts file.
  2. I've inherited the AfterViewChecked event and placed one line of code in there which states that the viewchild element has to take into the scrollTop value the value of scrollHeight (this.viewChildElement.nativeElement.scrollTop = this.viewChildElement.nativeElement.scrollHeight;)

The AfterViewChecked event fires a few times and it gets in the end the proper value from scrollHeight.

I have an Angular app with dynamic content and I tried several of the above answers with not much success. I adapted @Konard's answer and got it working in plain JS for my scenario:

HTML

<div id="app">
    <button onClick="scrollToBottom()">Scroll to Bottom</button>
    <div class="row">
        <div class="col-md-4">
            <br>
            <h4>Details for Customer 1</h4>
            <hr>
            <!-- sequence Id -->
            <div class="form-group">
                <input type="text" class="form-control" placeholder="ID">
            </div>
            <!-- name -->
            <div class="form-group">
                <input type="text" class="form-control" placeholder="Name">
            </div>
            <!-- description -->
            <div class="form-group">
                <textarea type="text" style="min-height: 100px" placeholder="Description" ></textarea>
            </div>
            <!-- address -->
            <div class="form-group">
                <input type="text" class="form-control" placeholder="Address">
            </div>
            <!-- postcode -->
            <div class="form-group">
                <input type="text" class="form-control" placeholder="Postcode">

                <div class="row">
                    <div class="col">
                        <button class="btn btn-success btn-block" data-toggle="tooltip" data-placement="bottom" title="Click to save">Save</button>
                        <button class="btn btn-success btn-block" data-toggle="tooltip" data-placement="bottom" title="Click to update">Update</button>
                    </div>
                    <div class="col">

                <hr>
            </div>
        </div>
    </div>
</div>

CSS

body {
    background: #20262E;
    padding: 20px;
    font-family: Helvetica;
}

#app {
    background: #fff;
    border-radius: 4px;
    padding: 20px;
    transition: all 0.2s;
}

JS

function scrollToBottom() {
    scrollInterval;
    stopScroll;

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

    var stopScroll = setInterval(function () {
        clearInterval(scrollInterval);
    }, 100);
}

A picture is worth a thousand words:

The key is:

document.documentElement.scrollTo({
  left: 0,
  top: document.documentElement.scrollHeight - document.documentElement.clientHeight,
  behavior: 'smooth'
});

It is using document.documentElement, which is the <html> element. It is just like using window, but it is just my personal preference to do it this way, because if it is not the whole page but a container, it works just like this except you'd change document.body and document.documentElement to document.querySelector("#container-id").

Example:

let cLines = 0;

let timerID = setInterval(function() {
  let elSomeContent = document.createElement("div");

  if (++cLines > 33) {
    clearInterval(timerID);
    elSomeContent.innerText = "That's all folks!";
  } else {
    elSomeContent.innerText = new Date().toLocaleDateString("en", {
      dateStyle: "long",
      timeStyle: "medium"
    });
  }
  document.body.appendChild(elSomeContent);

  document.documentElement.scrollTo({
    left: 0,
    top: document.documentElement.scrollHeight - document.documentElement.clientHeight,
    behavior: 'smooth'
  });

}, 1000);
body {
  font: 27px Arial, sans-serif;
  background: #ffc;
  color: #333;
}

You can compare the difference if there is no scrollTo():

let cLines = 0;

let timerID = setInterval(function() {
  let elSomeContent = document.createElement("div");

  if (++cLines > 33) {
    clearInterval(timerID);
    elSomeContent.innerText = "That's all folks!";
  } else {
    elSomeContent.innerText = new Date().toLocaleDateString("en", {
      dateStyle: "long",
      timeStyle: "medium"
    });
  }
  document.body.appendChild(elSomeContent);

}, 1000);
body {
  font: 27px Arial, sans-serif;
  background: #ffc;
  color: #333;
}

<script language="javascript" type="text/javascript">
function scrollToBottom() {
  $('#html, body').scrollTop($('#html, body')[0].scrollHeight);
}

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

If any one searching for Angular

you just need to scroll down add this to your div

 #scrollMe [scrollTop]="scrollMe.scrollHeight"

   <div class="my-list" #scrollMe [scrollTop]="scrollMe.scrollHeight">
   </div>

window.scrollTo(0,1e10);

always works.

1e10 is a big number. so its always the end of the page.

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);

So many answers trying to calculate the height of the document. But it wasn't calculating correctly for me. However, both of these worked:

jquery

    $('html,body').animate({scrollTop: 9999});

or just js

    window.scrollTo(0,9999);

For Scroll down in Selenium use below code:

Till the bottom drop down, scroll till the height of the page. Use the below javascript code that would work fine in both, JavaScript and React.

JavascriptExecutor jse = (JavascriptExecutor) driver; // (driver is your browser webdriver object) 
jse.executeScript("window.scrollBy(0,document.body.scrollHeight || document.documentElement.scrollHeight)", "");

You can attach any id to reference attribute href of link element:

<a href="#myLink" id="myLink">
    Click me
</a>

In the example above when user clicks Click me at the bottom of page, navigation navigates to Click me itself.

        div.scrollTop += 10; // move down

Here's my solution:

 //**** scroll to bottom if at bottom

 function scrollbottom() {
    if (typeof(scr1)!='undefined') clearTimeout(scr1)   
    var scrollTop = (document.documentElement && document.documentElement.scrollTop) || document.body.scrollTop;
    var scrollHeight = (document.documentElement && document.documentElement.scrollHeight) || document.body.scrollHeight;
    if((scrollTop + window.innerHeight) >= scrollHeight-50) window.scrollTo(0,scrollHeight+50)
    scr1=setTimeout(function(){scrollbottom()},200) 
 }
 scr1=setTimeout(function(){scrollbottom()},200)

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
