前景: 客户要求 后台管理系统 (element-UI) 能够填报 员工的 农历生日 !
试了 element 的 el-calendar 不是 很好用!
网上找到了此作者的笔记:
https://blog.csdn.net/qq_32109661/article/details/87794155,
借鉴的他的,现在 我把 根据需求 优化了一点点 后的 版本 分享给大家,
希望能帮助到你 ! 嘿嘿(^▽)
下面 我们进入正题:
1:因为可能 很多地方要用,我把它直接封装成一个组件(如下图):

2: 引入一个很关键的农历js,可自行百度,也可直接复制我下面分享的 !

3:效果图:

这里是dataPick.vue原码,可以直接拿着用,除了需要的数据处理那块,代码中我都有备注,你可自行修改:

到此处完结, 希望能够帮助到你 , 愿我们都在前进的道路上越来越顺 !!!

闲来无事做一些简单功能，一边练习VUE的使用，一边锻炼逻辑思维能力。之前有个项目需要自己写一个月份选择器，由此想起来做一个简单的日历，做起来有一些自己感兴趣的东西，也为了记录一下，发个帖

首先，我做的日历是没有农历的，因为我不知道农历的历法是怎么计算的，从网上找了一个似乎是很多年前的代码，功能不错，代码太乱就自己整理了一下，当然这段代码还是归写代码的大神所有，跟我没啥关系，特此声明

1、分享代码

Html代码

<template>
  <div class="main">
    <div class="choose_year">
      <div class="icon" @click="chooseYears(-1)"><i class="fa fa-angle-double-left"></i></div>
      <div class="icon" @click="chooseMonth(-1)"><i class="fa fa-angle-left"></i></div>
      <div class="date">{{year}}.{{month.toString().padStart(2, '0')}}</div>
      <div class="icon" @click="chooseMonth(1)"><i class="fa fa-angle-right"></i></div>
      <div class="icon" @click="chooseYears(1)"><i class="fa fa-angle-double-right"></i></div>
    </div>
    <div class="days_area">
      <div class="day week" v-for="week in weeks" :key="week">{{week}}</div>
      <div class="day" @click="chooseThisDay(day.gregorian)" v-for="(day, index) in days" :key="index" :class="day.gregorian === today ? 'choose_day' : ''">
        <p>{{day.gregorian}}</p>
        <span>{{day.lunar}}</span>
      </div>
    </div>
  </div>
</template>

SCSS代码

<style lang="scss" scoped>
  .main{
    .choose_year{
      display: flex;
      .icon{
        width: 10%;
        height: 8vh;
        line-height: 8vh;
        text-align: center;
      }
      .date{
        width: 60%;
        text-align: center;
        height: 8vh;
        line-height: 8vh;
        font-size: 1.2rem;
      }
    }
    .days_area{
      display: flex;
      flex-wrap: wrap;
      .day{
        width: 14.28%;
        text-align: center;
        padding: 1vh 0;
        margin-top: 1vh;
        p{
          margin: 0;
          font-size: 6vw;
        }
        span{
          font-size: 3vw;
        }
      }
      .week{
        background-color: dodgerblue;
        color: #fff;
        font-weight: bold;
        height: 6vh;
        line-height: 4vh;
        margin: 0;
      }
      .choose_day{
        background-color: dodgerblue;
        color: #fff;
        font-weight: bold;
      }
    }
  }
</style>

效果图

当然效果很一般啦，如果你要这种日历的话，自己精心调校一下样式应该...也比我好不到哪里去吧，哈哈哈哈

OK，代码就这些，有需要的话随便取用，除了我也不是很明白的农历日期计算之外，其他都是我写得简单代码，没什么技术含量，也就不需要赘述了
