dateTimePicker.js

function withData(param){
  return param < 10 ? '0' + param : '' + param;
}
function getLoopArray(start,end){
  var start = start || 0;
  var end = end || 1;
  var array = [];
  for (var i = start; i <= end; i++) {
    array.push(withData(i));
  }

    case '01':
    case '03':
    case '05':
    case '07':

 //处理传过来的字符串转化为数组

  // 默认开始显示数据 如果把自定义值传过来的话就使用自定义时间 否则用当前时间  ...dataArr数组解构

  /*年月日 时分秒*/

  dateTimeArray[4] = getLoopArray(0, 59);
  dateTimeArray[5] = getLoopArray(0, 59);
 //遍历dateTimeArray数组
  dateTimeArray.forEach((current,index) =>{
  //匹配defaultDate[index]值在current数组中的位置
    dateTime.push(current.indexOf(defaultDate[index]))
  });
  return {
    dateTimeArray: dateTimeArray,
    dateTime: dateTime
  }
}
module.exports = {
  dateTimePicker: dateTimePicker,
  getMonthDay: getMonthDay
}

需要用到的页面中

			<view class="login-Form">
				<view class="label">进场时间<text class="required">*</text></view>
				<picker class="warning-input" mode="multiSelector" :range="dateTimeArray" v-model="dateTime"
					@change="change" @columnchange="columnchange">
					<view class="inp-box" style="margin-left: 18px;">
						<input type="text" disabled="true" v-model="upTower" placeholder="请选择"
							placeholder-class="inputPlace" />
					</view>
				</picker>
			</view>

引入js，并调取方法

const dateTimePicker = require('@/pagesSitePurchase/sitePurchase/dateTimePicker.js')
	export default {
		data() {
			return {
				dateTimeArray: [],
				dateTime: "",
				upTower:""
			}
		},
		onLoad(e) {
			let date = new Date()
			let	Y = date.getFullYear() + '/'
			let	M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '/'
			// let	D = date.getDate() + ' '
			let	D = date.getDate()< 10 ? ('0' + date.getDate() + ' ') : (date.getDate() + ' ')
			
			
			let	h = date.getHours()< 10 ? ('0' + date.getHours() + ':') : (date.getHours() + ':')
			let	m = date.getMinutes()< 10 ? ('0' + date.getMinutes() + ':') : (date.getMinutes() + ':')
			let	s = date.getSeconds() < 10 ? '0' + date.getSeconds() : date.getSeconds()
				// h = '00' + ':',
				// m = '00' + ':',
				// s = '00';
			let arr = Y + M + D + h + m + s
			console.log(arr, 'arr1111')
			let obj = dateTimePicker.dateTimePicker(this.startYear, this.endYear, arr)
			console.log(obj, 'obj')
			this.dateTimeArray = obj.dateTimeArray
			this.dateTime = obj.dateTime
		},
		methods: {
		//时间格式化
			withData(param) {
				return param < 10 ? '0' + param : '' + param;
			},
			change(e) {
				let value = []
				e.detail.value.forEach((val, index) => {
					value.push(this.withData(val))
				})
				
				let allYear = this.dateTimeArray[0]
				let y = allYear[Number(value[0])];
				let m = Number(value[1]) + 1;
				let d = Number(value[2]) + 1;
				if (y < 10) y = '0' + y
				if (m < 10) m = '0' + m
				if (d < 10) d = '0' + d

				let dateArray = y + "-" + m + "-" + d + " " + value[3] + ":" + value[4] + ":" + value[5]
				this.upTower = dateArray
				this.formData.visitTime = dateArray
			},
			columnchange(e) {
				console.log(e.detail.value, 'e.detail.value111')
				let dateArr = this.dateTimeArray
				
				let arr = this.dateTime
				//滑动所在列的数据并对其值进行更新
				arr[e.detail.column] = e.detail.value
				//更新展示月份对应的天数（28 or 29 or 30 or 31）
				dateArr[2] = dateTimePicker.getMonthDay(dateArr[0][arr[0]], dateArr[1][arr[1]])
				//最后把最新的数值赋值到dateTimeArray
				this.dateTimeArray = dateArr
				this.dateTime = arr
			},
		}
