使用vue3对vant的日历组件进行改造能选上一年下一年上一个月下一个月

效果如图：

代码如下子组件

<!-- eslint-disable vue/no-v-model-argument -->
<template>
  <section class="home-page">
    <van-calendar
      ref="calendar"
      v-bind="$attrs"
      :min-date="dateRange[0]"
      :max-date="dateRange[1]"
      v-on="$attrs"
    >
      <template #subtitle>
        <van-icon name="arrow-left" size="16" @click="scrollToDate(-1,'year')" />
        <span @click="scrollToDate(-1,'month')">前一个月</span>
        <span class="tit">{{ dateInfo.title }}</span>
        <span @click="scrollToDate(1,'month')">后一个月</span>
        <van-icon name="arrow" size="16" @click="scrollToDate(1,'year')" />
      </template>
    </van-calendar>
  </section>
</template>

<script setup>

import moment from 'moment'
import { Toast } from 'vant'
import { ref, defineProps } from 'vue'
// props参数
const { date, dateRange } = defineProps({
  date: {
    type: Date,
    default: () => {
      return new Date()
    }
  },
  dateRange: {
    type: Array,
    default: () => {
      return [new Date(2010, 0, 1), new Date(2030, 12, 31)]
    }
  }
})
// data的数据
const dateInfo = ref({
  date: date,
  title: moment(date).format('YYYY年MM月')
})
// refs实例
const calendar = ref(null)
// 视图滚动到指定日期的视图
const scrollToDate = (type, dateType) => {
  // 生成新的时间
  const transDate = moment(dateInfo.value.date).add(type, dateType)
  // 做时间校验 校验成功则执行下面否则return
  if (!((transDate > dateRange[0]) && (transDate < dateRange[1]))) {
    return Toast.fail('已超出最大可选范围')
  }
  // 组合新的时间成对象类型
  const year = transDate.format('YYYY')
  const month = parseInt(transDate.format('MM'))
  const newDate = {
    date: new Date(transDate.format()),
    title: year + '年' + month + '月'
  }
  // 新的时间覆盖之前的时间
  dateInfo.value = newDate
  calendar.value.scrollToDate(new Date(dateInfo.value.date))
}
</script>

<style lang="less" scoped>
/deep/.van-calendar__header-subtitle {
	display: flex;
	align-items: center;
	justify-content: space-evenly;
	.tit {
		font-weight: 600;
		color: #1a73e8;
	}
}
</style>

父组件调用

<!-- eslint-disable vue/no-v-model-argument -->
<template>
  <section class="home-page">
    <van-cell title="选择多个日期" :value="text" @click="show = true" />
    <comp-calendar v-model:show="show" type="range" @confirm="onConfirm" /></section>
</template>

<script setup>
import CompCalendar from '@components/Calendar.vue'
import { ref } from 'vue'
const show = ref(false)
const text = ref(null)
const formatDate = (date) => `${date.getMonth() + 1}/${date.getDate()}`
const onConfirm = (values) => {
  const [start, end] = values
  show.value = false
  text.value = `${formatDate(start)} - ${formatDate(end)}`
}
</script>

<style lang="less" scoped>

</style>
