uniapp 小程序 picker 日期时间段选择（精确到年月日时分+周几）

效果图：

需要引入moment.js，有可能引入后在项目内会报错，可以考虑把选择日期作为一个组件引入

timepage.vue组件封装

<template><view><picker mode="multiSelector" :value="dateTimeIndex" :range="dateTimeArray" range-key="name"@change="dateTimeChange"><view class="uni-input"><text v-if="travelDate===''" style="color:#bbb">请选择</text><text v-else>{{moment(travelDate).format('YYYY年MM月DD日 HH:mm')}}</text></view></picker></view></template><script>import moment from '../../utils/moment.js'const dateTimeObj = (() => {const dateArr = []for (let i = 0; i < 50; i++) { // 默认50天const itemDate = moment().add(i, 'day');const d = itemDate.day();let week = '';if (d === 0) {week = '日'}if (d === 1) {week = '一'}if (d === 2) {week = '二'}if (d === 3) {week = '三'}if (d === 4) {week = '四'}if (d === 5) {week = '五'}if (d === 6) {week = '六'}dateArr.push({name: `${itemDate.format('YYYY年MM月DD日')}  周${week}`,value: itemDate.format('YYYY-MM-DD')})}const timeHHArr = [];for (let i = 0; i < 24; i++) {let str = i < 10 ? `0${i}` : `${i}`timeHHArr.push({name: str,value: str})}const timeMMArr = [];for (let i = 0;i<60;i++) {  let str = i<10?`0${i}`:`${i}`  timeMMArr.push({name:str,value:str})}return {dateArr,timeHHArr,timeMMArr}})()export default {components: {},props:{travelDate:{type:String,default: ''},dateTimeIndex:{type: Array,default: function () {return [0, 0, 0]}}},data() {return {moment: moment,dateTimeArray: [dateTimeObj.dateArr,dateTimeObj.timeHHArr,dateTimeObj.timeMMArr], //二维数组，长度是多少是几列// dateTimeIndex: [0, 0],}},methods: {dateTimeChange: function(e) {const d = dateTimeObj.dateArr[e.detail.value[0]].valueconst h = dateTimeObj.timeHHArr[e.detail.value[1]].valueconst m = dateTimeObj.timeMMArr[e.detail.value[2]].valuethis.$emit("timeSelect", `${d} ${h}:${m}`,e.detail.value);}}}</script><style lang="scss" scoped>.items{margin-bottom: 18rpx;}.items-text{font-size: 30rpx;line-height: 40rpx;letter-spacing: 1rpx;color: #333333;margin-bottom: 19rpx;}.select-input{width:100%;height: 88rpx;line-height: 88rpx;border-radius: 10rpx;border: 1rpx solid #BDBDBD;padding-left: 22rpx;box-sizing:border-box;}.time-select{display: flex;justify-content: space-evenly;padding-left: 0;font-size:30rpx;}</style>

3、需要显示时间组件的页面内引用时间组件

<template><view class="items"><view class="items-text">请选择时间段 (必填)</view><view class="select-input time-select"><time-page @timeSelect="timeSelectStart" :dateTimeIndex="startDateTimeIndex" :travelDate="startClearingTime"></time-page>至<time-page @timeSelect="timeSelectEnd" :dateTimeIndex="endDateTimeIndex" :travelDate="endClearingTime"></time-page></view></view><button class="btn-item " @click="toSubmit">提交</button></template><script>import timePage from '@/components/timepage/timepage.vue';export default {data() {const currentDate = this.getDate({format: true})return {startTimeNow: currentDate,//当前时间startClearingTime: '', //开始时间startDateTimeIndex:[0,0,0],//开始时间默认选择endClearingTime: '', //结束时间endDateTimeIndex:[0,0,0],//结束时间默认选择}},components: {timePage},methods: {// 当前时间getDate() {const date = new Date();let year = date.getFullYear();let month = date.getMonth() + 1;let day = date.getDate();let hour = date.getHours();let minute = date.getMinutes();month = month > 9 ? month : '0' + month;day = day > 9 ? day : '0' + day;hour = hour > 9 ? hour : '0' + hour;minute = minute > 9 ? minute : '0' + minute;return `${year}-${month}-${day} ${hour}:${minute}`;},// 提交toSubmit: function() {//以下为判断条件：非空判断、开始时间不得晚于结束时间、开始时间不得早于当前时间if (this.startClearingTime.length == 0) {uni.showToast({icon: 'none',title: "请选择开始时间",})return}if (this.startClearingTime < this.startTimeNow) {uni.showToast({icon: 'none',title: "请在当前时间后选择时间段",})return}if (this.endClearingTime.length == 0) {uni.showToast({icon: 'none',title: "请选择结束时间",})return}if (this.startClearingTime > this.endClearingTime) {uni.showToast({icon: 'none',title: "开始时间不得晚于结束时间",})return}}}}
