vue左右滑动选择日期组件封装
紫菀檀ss 人气:0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" :key="item" > {{item}} </div> </div> <div class="m-months-container" @touchstart="touchstart" @touchmove="touchmove" @touchend="touchend" > <div class="m-months-wrapper" :style="{'transform': `translate3d(${-translateX*100}%, 0, 0)`}" > <div class="m-months" v-for="(month,monthIndex) in fullDate" :key="monthIndex" :style="{ transform: `translate3d(${(monthIndex-1+translateX + (isTouching ? touch.x : 0))*100}%, 0, 0)`, transitionDuration: isTouching ?
