这篇文章主要为大家详细介绍了vue左右滑动选择日期组件封装的方法，文中示例代码介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
现在做的项目中遇到了左右滑动选择日期的一个功能，然后我封装了一下这个组件，现在分享给大家看一下：
效果图：
1、安装dayjs日期文件
npm install dayjs --save
2、封装的组件：
<template>
<div class="m-calendar" ref="calendar">
<div class="m-toolbar">
<div class="m-year-selector">
<!-- <a class="m-prev-btn" @click="changeYear('prev')"></a> -->
<span>{{showDate.year}}{{yearName}}</span>
<!-- <a class="m-next-btn" @click="changeYear('next')"></a> -->
</div>
<div class="m-month-selector">
<!-- <a class="m-prev-btn" @click="changeMonth('prev')"></a> -->
<span>{{monthNames[showDate.month-1]}}</span>
<!-- <a class="m-next-btn" @click="changeMonth('next')"></a> -->
</div>
</div>
<div class="m-week-header">
<div
class="m-week-day"
v-for="item in weekNames"

</div>
</div>
<div

transform: `translate3d(${(monthIndex-1+translateX + (isTouching ? touch.x : 0))*100}%, 0, 0)`,
transitionDuration: isTouching ? '0s' : '.3s',
}"
>
<div
