花了俩小时折腾出来的，jQuery人工智能聊天室长这样：
主要功能：
1.当然是聊天啦~点击飞机按钮或者回车可以发送消息到面板。
2.输入特定的内容，系统会给你相应的回复（这里我只设置了Hello，How are you和询问时间的自动回复）。
3.点击叉叉可以清除面板上的所有聊天记录。
4.问时间的时候，根据现在的时间，会给你相应的不同的回复，比如现在是22-23点，系统会回复你“good night”。
5.随着聊天的进行，聊天面板右侧的滚动条会一直维持在最底部。
HTML：
<div class="chat-box"> </div> <form class="form-inline chat-form"> <input type="text" class="form-control chat-message" placeholder="Say Something"> <button type="button" class="btn btn-primary chat-send" title="Send Message"> <i class="fa fa-paper-plane" aria-hidden="true"> </i> </button> <button type="reset" class="btn btn-success chat-reset" title="Reset Message"> <i class="fa fa-refresh" aria-hidden="true"> </i> </button> <button type="button" class="btn btn-danger chat-clear" title="Clear the Chat Box"> <i class="fa fa-times" aria-hidden="true"> </i> </button> </form> <hr> <footer> Designed By <a href="http://blog.csdn.net/alenhhy" rel="external nofollow" target="_blank"> Alen Hu </a> </footer>

JQuery:
$(document).ready(function() {
//send the message by click
$(".chat-send").click(sendMsg);
//press enter to send
$("form").keypress(function(event) {
if (event.keyCode === 13) {
event.preventDefault();
sendMsg();
}
});
//clear the chat box
$(".chat-clear").click(clearChatBox);
});
//send message to chat box

chatBox.append(msgAppend);
} else {}
//dialog reply

//empty input

//keep the scroll in bottom
chatBox.scrollTop(chatBox[0].scrollHeight);
}
//set up the AI dialog
function dialog(msg){
var replyArr = ["Hi, how's it going :)","I'm good, thx, U? :)"];
