滚动到 div 的底部？

Question

I am creating a chat using ajax requests in rails and I'm trying to get a div to scroll to the bottom without much luck.

I am wrapping everything in this div:

#scroll {
    height:400px;
    overflow:scroll;
}

Is there a way to keep it scrolled to the bottom by default using JS?

Is there a way to keep it scrolled to the bottom after an ajax request?

Here's what I use on my site:

var objDiv = document.getElementById("your_div");
objDiv.scrollTop = objDiv.scrollHeight;
