效果图与element原图

 

 el-calendar的尺寸

el-calendar的大小是根据内部每一个日历块进行决定的

    .el-calendar-day {
      height: 47px !important;
      border: none;
      text-align: center;
      padding: 0;
    }

右上角的上月下月，取消显示今天的css

// 今天按钮隐藏
    .el-button-group > .el-button:not(:first-child):not(:last-child) {
      display: none;
    }
    // 更改上月和下月样式
    .el-button-group > .el-button:first-child:before {
      content: "<";
      border: none;
      font-size: 20px;
      color: #979797;
    }

    .el-button-group > .el-button:last-child:before {
      content: ">";
      border: none;
      font-size: 20px;
      color: #979797;
    }
    // 按钮隐藏
    .el-button-group > .el-button:first-child span,
    .el-button-group > .el-button:last-child span {
      display: none;
    }

点击块出现背景色与下方小点

<template slot="dateCell" slot-scope="{ date, data }">
        <div
          :class="data.isSelected ? 'selected' : ''" //选中的状态
          style="width: 100%;height: 100%;padding-top: 5px;box-sizing: border-box;"
          @click="AddNewmsg(data)"
        >
          <p>{{ data.day.split("-")[2] }}</p>
          <div v-for="(i, index) in List">
            <div v-if='根据后端数据进行是否显示'  class="fleck"></div>
          </div>
        </div>
      </template>

上月下月点击事件

  mounted() {
    // 如果使用监听绑定数据会在点击今天按钮出现
    this.$nextTick(() => {
      // 点击前一个月
      let prevBtn = document.querySelector(
        ".el-calendar__button-group .el-button-group>button:nth-child(1)"
      );
      prevBtn.addEventListener("click", () => {
       //调用点击前一个月的函数，自己出入当前月份
            this.judgeDate(this.calendarDate);
      });
      let dayBtn = document.querySelector(
        ".el-calendar__button-group .el-button-group>button:nth-child(2)"
      );
      dayBtn.addEventListener("click", () => {
        this.judgeDate(this.calendarDate);
      });
      let nextBtn = document.querySelector(
        ".el-calendar__button-group .el-button-group>button:nth-child(3)"
      );
      nextBtn.addEventListener("click", () => {
        this.judgeDate(this.calendarDate);
      });
    });
  },
