vue/H5的日历组件可简单定制

在components创建riliZujian.vue

<template>
  <div class="max_box">
    <!-- 日历 文字 -->
    <div class="month">
      <div @click="lastMonth" class="monthText13">上月</div>
      <div class="monthText2">{{ year }}年{{ month }}月</div>
      <div class="monthText13" @click="nextMonth">下月</div>
    </div>

    <!-- 日历 周 -->
    <div class="week">
      <div v-for="weeks in weekArr" :key="weeks">
        {{ weeks }}
      </div>
    </div>

    <!-- 日历 日 -->
    <div class="day">
      <div
        :class="[{ checkday: !days.date }, { choose: days.flag }]"
        v-for="(days, index) in dayArr"
        :key="index"
      >
        {{ days.day }}
        <img src="./yidaka.png" class="dayImg" v-if="days.flag" />
      </div>
