1、组件代码 gy-calendar-self.vue

<template>
  <view class="calendar">
	<view class="selsct-date">
		请选择预约日期
	</view>
    <!-- 日历头部，显示星期 -->
    <view class="weekdays">
      <view v-for="day in weekDays" :key="day" class="weekday">{{ day }}</view>
    </view>

    <!-- 日历主体 -->
    <view class="calendar-body">
      <view v-for="(week, weekIndex) in calendarData" :key="weekIndex" class="week">
        <view
          v-for="(day, dayIndex) in week"

          :class="{'has-schedule': day.schState !== 0 }"
          class="day"
          :style="{ width: cellWidth + 'rpx' }"

2、引入

	<u-popup v-model="showCalendar" safe-area-inset-bottom mode="bottom">
		<data-calendar :scheduleData="selectedList" @selceted="selcetedDate"></data-calendar>
	</u-popup>
</view>
