How to Ensure Automatic Scrolling to the End of a Div Upon Data Insertion?

Ensuring Automatic Scrolling to End of Div Upon Data Insertion

To create a div that automatically scrolls to the end when new data is added, we can utilize JavaScript. This is particularly relevant when displaying data in a vertically scrollable div, ensuring that newly added content is visible without the need for manual scrolling.

Solution:

If the exact time of data insertion is unknown, a regular interval can be set to continuously adjust the scrollTop property of the div element to match its scrollHeight. This ensures that the div automatically scrolls to the end when new data is added.

The following JavaScript code snippet demonstrates this approach:

// Set an interval to update the scrollTop every 5 seconds
window.setInterval(function() {
  var elem = document.getElementById('data');
  elem.scrollTop = elem.scrollHeight;
}, 5000);

Alternatively, if the timing of data insertion is known, the JavaScript function can be explicitly called each time new data is added, ensuring immediate scrolling to the end.
