Element calendar 日历 扩展

原文：Element calendar农历日历 - Artemis6 - 博客园 (cnblogs.com)

element日历calendar组件上月、今天、下月、日历块点击事件及模板源码_vue.js_脚本之家 (jb51.net)

一、日历内部样式调整

lement组件calendar目前不支持农历日历，故引用中国农历（阴阳历）和西元阳历即公历互转JavaScript库。

自定义该组件主要为了实现多选日期 和 高亮显示节假日的功能。显示效果如下：

1、为了能用简单的html实现样例程序，将calendar.js的export去掉，通过JS引用的方式实现。

<!--vue引入 -->
<script src="https://cdn.staticfile.org/vue/2.5.2/vue.min.js"></script>
<!--element-ui引入组件 --> 
<script src="https://unpkg.com/element-ui/lib/index.js"></script>
<!--calendar引入 -->
<script src="calendar.js"></script> 

<!-- element-ui引入样式 --> 
<link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css">

2、添加el-calendar组件。通过设置名为 dateCell 的 scoped-slot 来自定义日历单元格中显示的内容。在 scoped-slot 可以获取到 date（当前单元格的日期）, data（包括 type，isSelected，day 属性）。

<div id="app">
    <el-calendar v-model="value" style=" 820px">
        <template slot="dateCell" slot-scope="{date, data}">
            <div :class="{ selected : isSelected(date, data) }">
                <div class="solar">{{ data.day.split('-')[2] }}</div>
                <div class="lunar" :class="{ festival : isFestival(date, data) }">{{ solarToLunar(date, data) }}</div>
            </div>
        </template>
    </el-calendar>
</div>

3、JavaScript实现是否选中、自定义日历显示内容的功能

var Main = {
    data() {
        return {
            // 设置value，会自动显示value对应月份，可以设置为selectedDates的第一个日期
            value: '2020-04-12',
            // 根据selectedDates设置选中日期
            selectedDates: ['2020-04-12','2020-04-15','2020-04-24']
        }
    },
    methods: {
        // 是否选中日期
        isSelected : function(slotDate, slotData) {
            return this.selectedDates.includes(slotData.day)
        },
        // 是否节假日
        isFestival(slotDate, slotData) {
            let solarDayArr = slotData.day.split('-');
            let lunarDay = calendar.solar2lunar(solarDayArr[0], solarDayArr[1], solarDayArr[2])

            // 公历节日农历节日农历节气
            let festAndTerm = [];
            festAndTerm.push(lunarDay.festival == null ? '' : ' ' + lunarDay.festival)
            festAndTerm.push(lunarDay.lunarFestival == null ? '' : '' + lunarDay.lunarFestival)
            festAndTerm.push(lunarDay.Term == null ? '' : '' + lunarDay.Term)
            festAndTerm = festAndTerm.join('')

            return festAndTerm != ''
        },
        // 公历转农历
        solarToLunar(slotDate, slotData) {
            let solarDayArr = slotData.day.split('-');
            let lunarDay = calendar.solar2lunar(solarDayArr[0], solarDayArr[1], solarDayArr[2])

            // 农历日期
            let lunarMD = lunarDay.IMonthCn + lunarDay.IDayCn

            // 公历节日农历节日农历节气
            let festAndTerm = [];
            festAndTerm.push(lunarDay.festival == null ? '' : ' ' + lunarDay.festival)
            festAndTerm.push(lunarDay.lunarFestival == null ? '' : '' + lunarDay.lunarFestival)
            festAndTerm.push(lunarDay.Term == null ? '' : '' + lunarDay.Term)
            festAndTerm = festAndTerm.join('')

            return festAndTerm == '' ? lunarMD : festAndTerm
        }
    }
}
var Ctor = Vue.extend(Main)
new Ctor().$mount('#app')

4、CSS实现自定义显示效果

    /**隐藏上一月、本月、下一月*/
    .el-calendar__button-group {
        display: none;
    }
    /**月份居中*/
    .el-calendar__title {
         100%;
        text-align: center;
    }
    /**日期div的样式*/
    .el-calendar-table tr td:first-child {
        border-left: 0px;
    }
    .el-calendar-table td {
        min-height: 110px;
        min- 110px;
        border-right: 0px;
    }
    .el-calendar-table td.is-selected {
        background-color: white;
    }
    .el-calendar-table .el-calendar-day {
        height: 100%;
        padding: 0px;
        text-align: center;
    }
    .el-calendar-table .el-calendar-day > div {
        height: 104px;
    }
    /**日期div的样式-公历*/
    .el-calendar-table .el-calendar-day > div .solar {
        padding-top: 30px;
    }
    /**日期div的样式-农历*/
    .el-calendar-table .el-calendar-day > div .lunar {
        padding-top: 10px;
    }
    /**日期div的样式-选中*/
    .el-calendar-table .el-calendar-day > div.selected {
        background-color: #fef2f2;
        border: 3px solid #fb0;
        border-radius: 20px;
    }

    /**本月周末设置为红色*/
    .el-calendar-table .current:nth-last-child(-n+2) .solar {
        color: red;
    }
    /**本月农历设置为灰色*/
    .el-calendar-table .current .lunar {
        color: #606266;
    }
    /**本月农历节日设置为红色*/
    .el-calendar-table .current .lunar.festival {
        color: red;
    }
    /**禁用点击效果*/
    /*.el-calendar-table td {*/
        /*pointer-events: none;*/
    /*}*/

 二、日历点击事件

<template>
 <div>
  <el-card class="_calendar">
   <el-container>
    <el-main>
     <el-card>
      <el-calendar v-model="value" :first-day-of-week="7">
       <!-- 这里使用的是 2.5 slot 语法，对于新项目请使用 2.6 slot 语法-->
       <template slot="dateCell" slot-scope="{date, data}">
        <div slot="reference" class="div-Calendar" @click="calendarOnClick(data)">
         <p :class="data.isSelected ? 'is-selected' : ''">
          {{ data.day.split('-').slice(1).join('-') }}
          <i
           :class="[data.isSelected ?'el-icon-check':'']"
          ></i>
          <i v-if="_.indexOf(isArrange, data.day)>0" class="el-icon-s-claim"></i>
          <!-- <i class="el-icon-coffee-cup"></i> -->
         </p>
