基于jQuery实现简单人工智能聊天室

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>

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 id='you'>You: </span>" + msgVal + "</p><hr class='you-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 id='ai'>AI: </span>" + replyArr[0] + "</p><hr class='ai-hr'>"); 
 } 
 else if(msg.indexOf("how are you") != -1 || msg.indexOf("how are u") != -1){ 
  chatBox.append("<p><span id='ai'>AI: </span>" + replyArr[1] + "</p><hr class='ai-hr'>"); 
 } 
 else if(msg.indexOf("time") != -1){ 
  chatBox.append("<p><span id='ai'>AI: </span>Current Time: " + currentTime + ". " + timeGreeting(hour) + "~ :)</p><hr class='ai-hr'>"); 
 } 
 else {} 
} 
 
//add 0 if time number is <10 
function plusZero(x){ 
 if(x < 10){ 
  x = "0" + x; 
 } 
 else { 
  x = x; 
 } 
 return x; 
} 
 
//greeting by hour 
function timeGreeting(h){ 
 var greeting = ["U need to sleep","Good morning","Lunch time now","Feel asleep","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(""); 
}
