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

getDocHeight: function() {
  var D = document;
  return Math.max(
    D.body.scrollHeight,
    D.documentElement.scrollHeight,
    D.body.offsetHeight,
    D.documentElement.offsetHeight,
    D.body.clientHeight,
    D.documentElement.clientHeight
  );
}

document.body.scrollTop = document.documentElement.scrollTop = this.getDocHeight();

Answer 2

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)

Answer 3

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>
            <!-- Image -->
            <div class="form-group">
                <img style="width: 100%; height: 300px;">
                <div class="custom-file mt-3">
                    <label class="custom-file-label">{{'Choose file...'}}</label>
                </div>
            </div>
            <!-- Delete button -->
            <div class="form-group">
                <hr>
                <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">
                        <button class="btn btn-danger btn-block" data-toggle="tooltip" data-placement="bottom" title="Click to remove">Remove</button>
                    </div>
                </div>
                <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);
}

Tested on the latest Chrome, FF, Edge, and stock Android browser. Here's a fiddle:

Answer 4

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.

Answer 5

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;
}

Answer 6

you can do this too with animation, its very simple

$('html, body').animate({
   scrollTop: $('footer').offset().top
   //scrollTop: $('#your-id').offset().top
   //scrollTop: $('.your-class').offset().top
}, 'slow');

hope helps, thank you
