uniapp 简易自定义日历

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"
          :key="dayIndex"
          @click="selectDate(day)"
          :class="{'has-schedule': day.schState !== 0 }"
          class="day"
          :style="{ width: cellWidth + 'rpx' }"
        >
          <view class="day-label">{{ day.dateLabel }}</view>
          <view v-if="day.day"
			class="day-status-has"
			:class="[day.info == '有' ? 'day-status-has' : day.info == '满' ? 'day-status-over' : 'day-status-none']"
			>
			  {{day.info}}
		  </view>
        </view>
      </view>
    </view>
  </view>
</template>

2、引入

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