这篇文章将为大家详细讲解有关如何封装vue日历组件，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。
具体内容如下
图示
封装的组件的代码如下
<template>
<div class="calendar">
<!-- 选择日历的弹出层 -->
<div class="model_mask" v-show="showtimemask" @click="showmask1()">
</div>
<div class="bouncedBox" v-show="showtimemask">
<div class="mobile-top">
<div class="sel-time">
<p>开始时间</p>
<p class="start-date">{{starttime.substring(0,4)+'-'+starttime.substring(4,6)+'-'+starttime.substring(6,8)}}
</p>
</div>
<div class="unsel-time">
<p>结束时间</p>
<p class="end-date">
{{endtime==''?'请选择结束日期':endtime.substring(0,4)+'-'+endtime.substring(4,6)+'-'+endtime.substring(6,8)}}</p>
</div>
</div>
<div class="title">
<div class="btn" @click.stop="last()" :class="(month<=nowmonth)&&(Year<=nowYear)?'noclick':'' ">上一月</div>
<div class="text">{{Year}}年{{month}}月</div>
<div class="btn" @click.stop="next()">下一月</div>
</div>
<div class="head">
<div class="days" v-for="(item,index) in ['星期日','星期一','星期二','星期三','星期四','星期五','星期六']" :key="index">
{{item}}
</div>
</div>

:item.count<nowtime?'noclick'
