javascript - 滚动到div的底部？(Scroll to bottom of div?)

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.

(我正在使用Rails中的Ajax请求创建聊天，并且试图使div滚动到底部没有太多运气。)

I am wrapping everything in this div:

(我将所有内容包装在这个div中：)

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

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

(有没有一种方法可以使用JS将其默认滚动到底部？)

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

(是否有办法在ajax请求后将其滚动到底部？)
