1、基本配置

<el-date-picker

            v-model="statisticsTime"

            :picker-options="pickerOptions"

            @focus="dateFocus"

            type="daterange"

            format="yyyy-MM-dd"

            value-format="yyyy-MM-dd"

            range-separator="至"

            start-placeholder="开始日期"

            end-placeholder="结束日期">

          </el-date-picker>

重点配置

            :picker-options="pickerOptions"

            @focus="dateFocus"

            data() {

                pickerOptions: {

                        onPick: ({maxDate, minDate}) => {

                              this.minDate = '';

                              this.minDate = minDate;

                        },

                        disabledDate: (time) => {

                              if(!this.minDate) return time.getTime() > Date.now();

                              let startDate = dayjs(this.minDate).subtract(12, "month");

                              let endDate = dayjs(this.minDate).add(12, "month");

                              endDate = endDate <= Date.now() ? endDate : Date.now();

                              return time.getTime() > endDate || time.getTime() < startDate;

                        }

          },

}

dateFocus() {

      this.minDate = "";

    },
