一、简介
剧情需要，找遍网络没找到合适的，由此想自己封装一个，主要是思路问题，理清思路很重要，这里我的思路采用了一个稍微简单的。
二、代码
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>分页插件</title>
</head>
<style type="text/css">
.box{
display: flex;
align-items: center;
justify-content: space-around;
width: 60%;
margin: 0 auto;
}
.box span{
display: flex;
padding: 5px 10px;
align-items: center;
justify-content: center;
border: 1px solid #000;
cursor: pointer;
}
.pageBox{
display: flex;
flex-direction: row;
justify-content: space-around;
}
.pageBox .active{
background: #000;
