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> </div> <form> <input type="text" placeholder="Say Something"> <button type="button" title="Send Message"> <i aria-hidden="true"> </i> </button> <button type="reset" title="Reset Message"> <i aria-hidden="true"> </i> </button> <button type="button" title="Clear the Chat Box"> <i aria-hidden="true"> </i> </button> </form> <hr> <footer> Designed By <a href="https://blog.csdn.net/alenhhy" target="_blank"> Alen Hu </a> </footer>
*使用了Bootstrap3框架。
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 function sendMsg() { var msg = $(".chat-message"); var msgVal = msg.val(); var chatBox = $(".chat-box"); if (msgVal) { var msgAppend = "<p><span>You: </span>" + msgVal + "</p><hr>"; chatBox.append(msgAppend); } else {} //dialog reply dialog(msgVal); //empty input msg.val(""); //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? :)"]; msg = msg.toLowerCase(); var time = new Date(); var hour = time.getHours(); var minute = time.getMinutes(); var currentTime = plusZero(hour) + ":" + plusZero(minute); var chatBox = $(".chat-box"); if(msg.indexOf("hello") != -1){ chatBox.append("<p><span>AI: </span>" + replyArr[0] + "</p><hr>"); } else if(msg.indexOf("how are you") != -1 || msg.indexOf("how are u") != -1){ chatBox.append("<p><span>AI: </span>" + replyArr[1] + "</p><hr>"); } else if(msg.indexOf("time") != -1){ chatBox.append("<p><span>AI: </span>Current Time: " + currentTime + ".

Have some coffee","Free time~Yeah","Good night"]; if(h>=0&&h<=6){ return greeting[0]; } else if(h>=7&&h<=10){ return greeting[1]; } else if(h>=11&&h<=13){ return greeting[2]; } else if(h>=14&&h<=18){ return greeting[3]; } else if(h>=19&&h<=21){ return greeting[4]; } else if(h>=22&&h<=23){ return greeting[5]; } else { return ""; } } //clear the chat box function clearChatBox() { $(".chat-box").html(""); }
