Instructions for creating a scrollable unordered list when it reaches its maximum capacity

My HTML code has a <ul> element with the following structure:

<ul id="messages">

</ul>

In my HTML file, I have not specified any <li> items. However, in my JavaScript code using jQuery, I dynamically add <li> items to the <ul> element.

$("#messages").append("<li>" + string + "</li>");

The issue I am facing is that when the list gets too long to fit on the screen, the newly added <li> items are not automatically scrolled into view. How can I make sure that the list scrolls down to show the latest items?

Are you seeking a way to automatically scroll the page down to a specific list item when it is added?

To achieve this, you can utilize jQuery and JavaScript to determine the offset of the <li> element from the top of the window. Once you have this information, you can then scroll the window to that position.

var offset = $('li').offset().top;

$('body').scrollTop(offset);

Here's a sample demonstration

If you prefer to animate the scrolling effect, you can use a code snippet like the following:

$('html,body').animate({
      scrollTop: offset
}, 1000);

I have implemented this on a click event since the timing of when you add the item is not specified

The necessary HTML for a functional example is as follows:

<button id="click">Click me</button>
<ul id="messages">

</ul>

The jQuery code snippet is as follows:

 $(document).ready(function (){
        $("#click").click(function (){ 
            $("#messages").append("<li>pow</li>");
            //$(this).animate(function(){
                $('html, body').animate({
                    scrollTop: $("#messages li").last().offset().top
                }, 2000);
            //});
        });
    });
