Scroll to bottom of div?

Question

I am creating a chat using Ajax requests and I\'m trying to get messages div to scroll to the bottom without much luck.

I am wrapping everything in this div:

Answer 1

Javascript or jquery:

var scroll = document.getElementById('messages');
   scroll.scrollTop = scroll.scrollHeight;
   scroll.animate({scrollTop: scroll.scrollHeight});

Css:

 .messages
 {
      height: 100%;
      overflow: auto;
  }
