vue实现日历

  之前在上家公司做过一个公司人员考勤的东西,里面需要用到日历,当时自己用vue随便写了一个,比较简单,删掉了其他功能的代码,只留下日历,直接看代码

<template>
    <div class="lookForMonth_wrapper">
        <div class="lookForMonth_top">
            <div class="selectDate">
                <div>{{year}} 年 {{month}} 月</div>
                <div class="upDownSelect">
                    <div class="upDownSelect_item" @click="dateUp"></div>
                    <div class="upDownSelect_item" @click="dateDown"></div>
                </div>
            </div>
        </div>
        <div class="calendar" :style="calendarStyle">
            <div v-for="(item,index) in calendarData" class="calendar_item" :key=‘index‘ :class="{ash:item.color===‘ash‘,date:index>6&&item.color!==‘ash‘}">
              <p class="dateEdit">{{item.label}}<i class="el-icon-edit-outline" v-if="item.color!==‘ash‘&&index>=7"></i></p>
              <p v-if=‘index>6‘>上班</p>  // 打工人
            </div>
        </div>
    </div>
</template>
<script>
export default {
  name: "lookForMonth",
  data: () => {
    return {
      calendarData: [{label:"日"},{label: "一"}, {label:"二"},{label: "三"},{label: "四"},{label: "五"},{label: "六"}], //日历循环渲染数据
      year: 0, //当前日期年
      month: 0, //当前日期月数
      date: 0, //当前日期号数
      day: -1, //当前星期几
    };
  },
  filters:{
  },
  computed: {
    // 根据当月日期详情更改日历表格高度
    calendarStyle() {
      if (this.calendarData.length > 42) {
        return "height: 701px;";
      } else {
        return "height: 601px;";
      }
    }
  },
  async created(){
    // 获取当前日期数据
    this.getNow();
    // 获取当前月份一号的时间戳
    let firstTime = +new Date(this.year,this.month-1,1,0,0,0)
    this.getCalendarDate();   // 给calendarData添加当月数据
  },
  mounted() {
  },
  methods: {
    // 获取当前时间
    getNow() {
      let now = new Date()
      this.year = +now.getFullYear()
      this.month = +now.getMonth() + 1
      this.date = +now.getDate()
      this.day = +now.getDay()
    },
    // 获取每个月的天数
    monthDay(month) {
      if ([1,3,5,7,8,10,12].includes(month)) {
        return 31
      } else if ([4,6,9,11].includes(month)) {
        return 30
      } else if (month === 2) {
        //  判断当年是否为闰年
        if (
          (this.year % 4 === 0 && this.year % 100 !== 0) ||
          this.year % 400 === 0
        ) {
          return 29
        } else {
          return 28
        }
      }
    },
    // 给calendarData添加当月数据
    getCalendarDate() {
      // 获取当前月份一号星期几
      let firstDay = new Date(this.year + "-" + this.month + "-" + "01").getDay();
      this.calendarData = [{label:"日"},{label: "一"}, {label:"二"},{label: "三"},{label: "四"},{label: "五"},{label: "六"}];
      let num = parseInt(firstDay);
      let nowDays = this.monthDay(this.month);
      let lastMonth = this.month - 1>0?this.month - 1:12;
      let lastDays = this.monthDay(lastMonth);
      //   循环添加上一个月数据
      for (let i = 0; i < num; i++) {
        this.calendarData.push({label:lastDays - num + i + 1,color:‘ash‘});
      }

        this.calendarData.push({label:i + 1});
      }
      // 循环添加下一个月数据
      if (this.calendarData.length % 7 !== 0) {
        let surplusDay = 7 - (this.calendarData.length % 7);
        for (let i = 0; i < surplusDay; i++) {
          this.calendarData.push({label:i + 1,color:‘ash‘});
        }
      }
      this.loading = false
    },
    // 将日期调上
    dateUp() {
      this.month--;
      if (this.month <= 0) {
        this.year--;
        this.month = 12;
      }
      this.getCalendarDate();   // 给calendarData添加当月数据
    },
    // 将日期调下
    dateDown() {
      this.month++;
      if (this.month > 12) {
        this.year++;
        this.month = 1;
      }
      this.getCalendarDate();   // 给calendarData添加当月数据
    },
  }
};

<style lang="scss" scoped>
.lookForMonth_wrapper {

        &:hover {
          border-bottom: 7px solid skyblue;
        }
      }
      .upDownSelect_item:nth-child(2) {
        border-top: 7px solid #666;
        &:hover {
          border-top: 7px solid skyblue;
        }
      }
    }
  }
}
/* 日历表样式=======================================↓ */
.calendar {
  width: 701px;
  border-top: 1px solid #ccc;
  border-left: 1px solid #ccc;
  display: flex;
  flex-wrap: wrap;
  box-sizing: border-box;
  .calendar_item {
    box-sizing: border-box;
    width: 100px;
    height: 100px;
    border-right: 1px solid #ccc;
    border-bottom: 1px solid #ccc;
    text-align: center;
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
    &.date:hover{
      background: #eee;
    }
    .status{
      margin-top: 10px;
      &.textBlue{
        color: blue;
      }
      &.textRed{
        color: brown;
      }
    }
    .el-icon-edit-outline{
      cursor: pointer;
      margin-left: 7px;
    }
  }
  .ash{
    color: gainsboro;
  }
  .dateEdit{
    margin-bottom: 10px;
  }
}
</style>

效果如下:
