声明

我参考大佬文章 最初的样子，在此基础上，做一些修改，利用微信小程序的picker组件的多列选择器实现成这样

外部JS，dateTimePicker.js的引入

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));
  }
  return array;
}
function getMonthDay(year,month){
  var flag = year % 400 == 0 || (year % 4 == 0 && year % 100 != 0), array = null;

  switch (month) {
    case '01':
    case '03':
    case '05':
    case '07':
    case '08':
    case '10':
    case '12':
      array = getLoopArray(1, 31)
      break;
    case '04':
    case '06':
    case '09':
    case '11':
      array = getLoopArray(1, 30)
      break;
    case '02':
      array = flag ? getLoopArray(1, 29) : getLoopArray(1, 28)
      break;
    default:
      array = '月份格式不正确，请重新输入！'
  }
  return array;
}
function getNewDateArry(){
  // 当前时间的处理
  var newDate = new Date();
  var year = withData(newDate.getFullYear()),
      mont = withData(newDate.getMonth() + 1),
      date = withData(newDate.getDate()),
      hour = withData(newDate.getHours()),
      minu = withData(newDate.getMinutes()),
      seco = withData(newDate.getSeconds());

  return [year, mont, date, hour, minu, seco];
}
function dateTimePicker(startYear,endYear,date) {
  // 返回默认显示的数组和联动数组的声明
  var dateTime = [], dateTimeArray = [[],[],[],[],[],[]];
  var start = startYear || 1978;
  var end = endYear || 2100;
  // 默认开始显示数据
  var defaultDate = date ? [...date.split(' ')[0].split('-'), ...date.split(' ')[1].split(':')] : getNewDateArry();
  // 处理联动列表数据
  /*年月日 时分秒*/
  dateTimeArray[0] = getLoopArray(start,end);
  dateTimeArray[1] = getLoopArray(1, 12);
  dateTimeArray[2] = getMonthDay(defaultDate[0], defaultDate[1]);
  dateTimeArray[3] = getLoopArray(0, 23);
  dateTimeArray[4] = getLoopArray(0, 59);
  dateTimeArray[5] = getLoopArray(0, 59);

  dateTimeArray.forEach((current,index) => {
    dateTime.push(current.indexOf(defaultDate[index]));
  });

  return {
    dateTimeArray: dateTimeArray,
    dateTime: dateTime
  }
}
module.exports = {
  dateTimePicker: dateTimePicker,
  getMonthDay: getMonthDay
}

页面js

引入dateTimePicker.js

data: {
    dateTimeArray1: null,
    dateTime1: null,
    startYear: null,
    endYear: null,
  },
onLoad: function(options) {
    // 获取完整的年月日 时分秒，以及默认显示的数组
    var obj1 = dateTimePicker.dateTimePicker(this.data.startYear, this.data.endYear);
    // 精确到分的处理，将数组的秒去掉
    //var lastArray = obj1.dateTimeArray.pop();
    //var lastTime = obj1.dateTime.pop();

    this.setData({
      dateTimeArray1: obj1.dateTimeArray,
      dateTime1: obj1.dateTime
    });
  },
  // 选择日期时间
changeDateTime1(e) {
  this.setData({
    dateTime1: e.detail.value,
  });

  var arr = this.data.dateTime1,
    dateArr = this.data.dateTimeArray1;

  arr[e.detail.column] = e.detail.value;
  //判断这个月几天
  dateArr[2] = dateTimePicker.getMonthDay(dateArr[0][arr[0]], dateArr[1][arr[1]]);
  var dateStr = dateArr[0][arr[0]] + '-' + dateArr[1][arr[1]] + '-' + dateArr[2][arr[2]] + ' ' + dateArr[3][arr[3]] + ':' + dateArr[4][arr[4]] + ':' + dateArr[5][arr[5]];

  this.setData({
    dateStr: dateStr,
  });
},

wxml

<picker class="options" mode="multiSelector" value="{{dateTime1}}" bindchange="changeDateTime1"
        range="{{dateTimeArray1}}">
  <input disabled class="order-input" placeholder="开始时间"
         value='{{dateStr}}'/>
</picker>

wxss

自己按需要写啦！

痛批与推荐

这种有引入组件的方式，订阅专栏竟然要钱，日期时间选择器（年月日时分秒）_微信小程序日期时间选择器，纯属恶心人，我更推荐大家去看一看这个GitHub项目GitHub - binfy/DatePicker上这个感觉效果更好
