Establishing the initial position of the scrollbar at a specific height

I am curious if it is feasible to configure a starting position for a scrollbar in js/jquery/css/html.

https://i.sstatic.net/ARlbH.png

Looking at the provided screenshot, I would like the scrollbar to always stay updated and remain at the bottom whenever a new message comes through or when the page is initially loaded.

<div class='media'>
      <a class='pull-left' href='#'>
          <img class='media-object img-circle' src='img/avatar' alt='Avatar'>
      </a>

      <div class='media-body'>
            <h5 class='media-heading'>/username/</h5>
            <h5>/message/</h5>
      </div>
</div><hr>

Answer №1

To utilize pure JavaScript, all that is required is updating the scrollTop value to match the scrollHeight.

The image provided demonstrates the relationship between scrollHeight and scrollTop within a vertically scrollable container.

Here is an example:

var myElement = document.getElementById("myElement");
myElement.scrollTop = myElement.scrollHeight;

This is the code I am currently using:

var makescrollbottom = function(){
    $("div.media").scrollTop($("div.media").prop("scrollHeight"));
}
makescrollbottom();
