vue怎么实现左右滑动选择日期组件

今天小编给大家分享一下vue怎么实现左右滑动选择日期组件的相关知识点，内容详细，逻辑清晰，相信大部分人都还太了解这方面的知识，所以分享这篇文章给大家参考一下，希望大家阅读完这篇文章后有所收获，下面我们一起来了解一下吧。

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"        :      >        <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 ? '0s' : '.3s',          }"        >          <div            class="m-row"            v-for="(week,weekIndex) in month"            :key="weekIndex"          >            <div              class="m-day"              v-for="(day,dayIndex) in week"              :key="dayIndex"              @click="onDayClick(day)"            >              <span                :class="{                  'm-day-num':true,                  'm-grey': day.isGrey,                  'm-today': day.isToday,                  'm-disable': day.isDisable,                  'm-select': day.isSelect,                }"              >                  <!-- 'm-during': day.isDuring -->                {{day.value}}              </span>              <slot name="day" :date="day" />            </div>          </div>        </div>      </div>    </div>  </div></template><script>import dayjs from 'dayjs';let touchStartPosition;let touchEndPosition;let timeStamp;export default {  name: 'inlineCalendar',  props: {    defaultDate: {      type: [Date, Number, Array, String, dayjs],    },    disabledDate: {      type: Array,      default() {        return [];      },    },    minDate: {      type: [Date, Number, Array, String, dayjs],    },    maxDate: {      type: [Date, Number, Array, String, dayjs],    },    mode: {      type: String,      default: 'single',    },    dayClick: {      type: Function,      default() {        return function() {          return true;        };      },    },    enableTouch: {      type: Boolean,      default: true,    },    monthNames: {      type: Array,      default() {        return ['1月', '2月', '3月', '4月', '5月', '6月', '7月', '8月', '9月', '10月', '11月', '12月'];      },    },    weekNames: {      type: Array,      default() {        return ['一', '二', '三', '四', '五', '六', '日'];      },    },    yearName: {      type: String,      default: '年',    },    restrictCurrentMonth: {      type: Boolean,      default: false,    },  },  watch: {    mode() {      this.init();    },  },  data() {    return {      fullDate: [[], [], []],      translateX: 0,      showDate: {        year: undefined,        month: undefined,      },      dateNow: {        year: dayjs().year(),        month: dayjs().month() + 1,        date: dayjs().date(),      },      selectDate: [],      touch: {        x: 0,        y: 0,      },      isTouching: false,    };  },  created() {    this.init();  },  methods: {    init(date) {      this.selectDate = [];      let { defaultDate, mode } = this;      if (date) {        defaultDate = date;      }      let dateToShow = dayjs().startOf('month');      if (mode === 'single' && defaultDate) {        this.selectDate = dayjs(defaultDate).startOf('day');        dateToShow = this.selectDate.startOf('month');      }      if (mode === 'multiple' && Array.isArray(defaultDate)) {        if (defaultDate.length > 0) {          this.selectDate = defaultDate.map((item) => dayjs(item).startOf('day'));        }      }      if (mode === 'during' && Array.isArray(defaultDate)) {        if (defaultDate.length === 2) {          const startDate = dayjs(defaultDate[0]).startOf('day');          const endDate = dayjs(defaultDate[1]).startOf('day');          if (startDate.isBefore(endDate) || startDate.isSame(endDate)) {            this.selectDate = [startDate, endDate];          }        }      }      this.showDate = {        year: dateToShow.year(),        month: dateToShow.month() + 1,      };      this.getFullDate(this.showDate);    },    touchstart(event) {      if (this.enableTouch) {        touchStartPosition = event.touches[0].clientX;        touchEndPosition = event.touches[0].clientY;        timeStamp = event.timeStamp;        this.touch = {          x: 0,          y: 0,        };        this.isTouching = true;      }    },    touchmove(event) {
