<el-date-picker class="hoverPoint"

        pickerOptions0: {
                disabledDate: (time) => {
                    if (this.beginTime != "") {
                        return time.getTime() > new Date(new Date().getTime() - 7 * 24 * 3600 * 1000) || time.getTime() > this.beginTime;
                    } else {
                        return time.getTime() > Date.now();
                    }
                }
