• 下面是DOM

 <el-calendar>
      <template slot="dateCell" slot-scope="{ data }">
        <div
          slot="reference"
          class="div-Calendar"
          @click="calendarOnClick(data)"
        >
          <p :class="data.isSelected ? 'is-selected' : ''">
            <span :class="(data.day>=startTime&&data.day<=endTime)||data.day==startTime?'active':''">{{
              data.day.split("-").slice(2).join("-")
            }}</span>
          </p>
        </div>
      </template>
    </el-calendar>

• data

  data() {
    return {
      startTime: "",
      endTime: "",
      nowDate: new Date(),
      clickcount: 0,
      clickitem: "",
    };
  },

• methods

  calendarOnClick(e) {
      this.clickcount++;
      this.clickitem = e.day;
      //开始日期
      if (this.clickcount % 2 == 1) {
        this.startTime = this.clickitem;
        this.endTime = "";
      } else {
        this.endTime = this.clickitem;
        if (this.startTime > this.endTime) {
          this.endTime = this.startTime;
          this.startTime = this.clickitem;
        }
      }
      console.log(this.startTime);
