今天遇到需求是配送时间，时隔半个钟的排线！所以需要拼接时间！例如2024-10-08 14：30，2024-10-08 15：00，2024-10-08 15：30

<el-form-item label="配送时间：" prop="spOrderTime"><el-select v-model="form.spOrderTime" clearable style="width: 240px" @change="changeOrderTime"><!-- <el-option v-for="item in Config.selectTimeOption" :key="item.value" :label="item.label":value="item.value"></el-option> --><el-option v-for="item in Config.selectTimeOption" :key="item.index" :label="item.value":value="item.value"></el-option></el-select>
</el-form-item>

// 获取配送时间数组deliveryTimeList() {const now = dayjs();// 获取当前时间const threeDaysLater = now.add(2, 'day').endOf('day'); //3天后的日期const timePoints = [];//每个半小时整点的时间点let currentTime = now.startOf('hour');// 如果当前时间不是00分或30分，则跳到下一个半小时整点if (currentTime.minute() !== 0 && currentTime.minute() !== 30) {if (currentTime.minute() < 30) {currentTime = currentTime.set('minute', 30);} else {currentTime = currentTime.add(1, 'hour').startOf('hour');}}// 循环生成每个半小时整点的时间点let index=0while (currentTime.isBefore(threeDaysLater) || currentTime.isSame(threeDaysLater)) {timePoints.push({index:index,value:currentTime.format('YYYY-MM-DD HH:mm')});currentTime = currentTime.add(30, 'minute'); index++}// 赋值this.Config.selectTimeOption = timePointsthis.form.spOrderTime=timePoints[0].value},
