I am currently working on a chat window within a div. When new messages are added and displayed at the bottom of the chat, I would like the content to automatically scroll down so that the most recent message is visible.
<div id="chat">
</div><!--end of chat-->
If you want to create a smooth scrolling effect in your chat window, simply animate the CSS value scrollTop to match the content height of the container, also known as scrollHeight.
Check out this example code snippet that demonstrates how to achieve this effect. You can see it in action by visiting this fiddle: http://jsfiddle.net/bFx8Y/
// determine the new height of the chat window
var newHeight = $('#chat_window')[0].scrollHeight;
$('#chat_window').animate({scrollTop:newHeight}, 1000); // If preferred, you can use .css() instead for an immediate change
To achieve this, simply utilize jQuery's scrollTop() function.
