jquery与vue实现多级评论和回复的功能代码对比
jquery是dom操作的辅助工具，随着html5的发布，jquery逐渐也退出历史的舞台，我接替jquery的就是虚拟dom插件，而虚拟dom插件中属vue比较流行，今天我们来通过用jquery和vue分别写一个多级评论和回复的页面效果，看看jquey和vue的真实差别到底在哪？
一、评论数据源
评论数据源我们采用的嵌套式数据结构，顶级评论的pid为0，子评论或回复的pid为上一级的id，每个评论都有子评论replyComments数组，如果没有就是空数组，有的话就是一个评论数组，数据源如下表，可以在mysql中创建好数据结构，然后取出来的时候通过递归形成下面的数据结构。
var comments= [{
"id": 1,
"pid": 0,
"nickname": "张三",
"content": "你们好",
"createTime": "2020-04-12T06:32:20.613+0000",
"replyComments": [{
"id": 2,
"pid": 1,
"nickname": "李四",
"content": "你好",
"createTime": "2020-04-12T06:32:31.699+0000",
"replyComments": []
}]
},
{
"id": 3,
"pid": 0,
"nickname": "王五",
"content": "猪吗？",
"createTime": "2020-04-12T06:34:37.146+0000",
"replyComments": [{
"id": 4,
"pid": 3,
"nickname": "赵六",
"content": "？？",
"createTime": "2020-04-12T07:03:47.873+0000",
"replyComments": [{
"id": 5,
"pid": 4,
"nickname": "老李",
"content": "你们在耍啥",
"createTime": "2020-04-12T07:03:47.873+0000",
"replyComments": []
}]
}]
},
];
二、评论html
这是一个嵌套式的多楼层评论html效果，不管通过jquery还是vue，最终的效果都是这样的。<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,initial-scale=1.0,maximum=1.0,minimum=1.0,user-scalable=0" />
<style>
.comment-box{
padding: 5px 10px;
border: 1px solid grey;
margin:5px;
}
.reply{
color: red;
font-weight: bold;
}
</style>
</head>
<body>
<div id="comment"><div class="comment-box"><span>张三说</span> <span>你们好</span> <span toid="1" touser="张三" class="reply">回复</span><div class="comment-box"><span>李四回复说</span> <span>你好</span> <span toid="2" touser="李四" class="reply">回复</span></div></div><div class="comment-box"><span>王五说</span> <span>猪吗？</span> <span toid="3" touser="王五" class="reply">回复</span><div class="comment-box"><span>赵六回复说</span> <span>？？</span> <span toid="4" touser="赵六" class="reply">回复</span><div class="comment-box"><span>老李回复说</span> <span>你们在耍啥</span> <span toid="5" touser="老李" class="reply">回复</span></div></div></div></div>
</body>
</html>
三、jquery实现多级评论
jquery主要通过each对数组进行循环，然后进行递归输出一个总的html字符串，最后再插入到dom节点中，完整代码如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width,initial-scale=1.0,maximum=1.0,minimum=1.0,user-scalable=0" />
<script type="text/javascript" src="//repo.bfw.wiki/bfwrepo/js/jquery.17.js"></script>
<script type="text/javascript">
$(function() {
var comments= [{
"id": 1,
"pid": 0,
"nickname": "张三",
"content": "你们好",
"createTime": "2020-04-12T06:32:20.613+0000",
"replyComments": [{
"id": 2,
"pid": 1,
"nickname": "李四",
"content": "你好",
"createTime": "2020-04-12T06:32:31.699+0000",
"replyComments": []
}]
},
{
"id": 3,
"pid": 0,
"nickname": "王五",
"content": "猪吗？",
"createTime": "2020-04-12T06:34:37.146+0000",
"replyComments": [{
"id": 4,
"pid": 3,
"nickname": "赵六",
"content": "？？",
"createTime": "2020-04-12T07:03:47.873+0000",
"replyComments": [{
"id": 5,
"pid": 4,
"nickname": "老李",
"content": "你们在耍啥",
"createTime": "2020-04-12T07:03:47.873+0000",
"replyComments": []
}]
}]
},
];
$("#comment").html(diGui(comments))
$(".reply").click(function(){
