声明

bug：由于此篇博客是在bindcolumnchange事件中做的值的改变处理，因此会出现当你选择时，没有点击确定，直接取消返回后，会发现选择框的值依然改变。造成原因：这一点就是由于在bindcolumnchange事件做的值改变处理造成。处理方法：如果需要确定后再改变值，请将bindcolumnchange事件中的处理操作放到bindchange事件中。感谢：感谢qq_41906890指出的问题！

效果图

实现原理

利用微信小程序的picker组件的多列选择器实现！

WXML

<view class="tui-picker-content">
  <view class="tui-picker-name">时间选择器（选择时分）</view>
  <picker mode="time" value="{{time}}" start="09:00" end="17:30" bindchange="changeTime">
    <view class="tui-picker-detail">
      午饭时间: {{time}} 
    </view>
  </picker>
</view>

<view class="tui-picker-content">
  <view class="tui-picker-name">日期选择器（选择年月日）</view>
  <picker mode="date" value="{{date}}" start="2017-10-01" end="2017-10-08" bindchange="changeDate">
    <view class="tui-picker-detail">
      国庆出游: {{date}}
    </view>
  </picker>
</view>

<view class="tui-picker-content">
  <view class="tui-picker-name">日期时间选择器（精确到秒）</view>
  <picker mode="multiSelector" value="{{dateTime}}" bindchange="changeDateTime" bindcolumnchange="changeDateTimeColumn" range="{{dateTimeArray}}">
    <view class="tui-picker-detail">
      选择日期时间: {{dateTimeArray[0][dateTime[0]]}}-{{dateTimeArray[1][dateTime[1]]}}-{{dateTimeArray[2][dateTime[2]]}} {{dateTimeArray[3][dateTime[3]]}}:{{dateTimeArray[4][dateTime[4]]}}:{{dateTimeArray[5][dateTime[5]]}}
    </view>
  </picker>
</view>
<view class="tui-picker-content">
  <view class="tui-picker-name">日期时间选择器（精确到分）</view>
  <picker mode="multiSelector" value="{{dateTime1}}" bindchange="changeDateTime1" bindcolumnchange="changeDateTimeColumn1" range="{{dateTimeArray1}}">
    <view class="tui-picker-detail">
      选择日期时间: {{dateTimeArray1[0][dateTime1[0]]}}-{{dateTimeArray1[1][dateTime1[1]]}}-{{dateTimeArray1[2][dateTime1[2]]}} {{dateTimeArray1[3][dateTime1[3]]}}:{{dateTimeArray1[4][dateTime1[4]]}}
    </view>
  </picker>
</view>

WXSS

@import "../picker/picker.wxss";

使用的是三级联动选择器的样式，所以直接 import 引入！

JS

var dateTimePicker = require('../../utils/dateTimePicker.js');

Page({
  data: {
    date: '2018-10-01',
    time: '12:00',
    dateTimeArray: null,
    dateTime: null,
    dateTimeArray1: null,
    dateTime1: null,
    startYear: 2000,
    endYear: 2050
  },
  onLoad(){
    // 获取完整的年月日 时分秒，以及默认显示的数组
    var obj = dateTimePicker.dateTimePicker(this.data.startYear, this.data.endYear);
    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({
      dateTime: obj.dateTime,
      dateTimeArray: obj.dateTimeArray,
      dateTimeArray1: obj1.dateTimeArray,
      dateTime1: obj1.dateTime
    });
  },
  changeDate(e){
    this.setData({ date:e.detail.value});
  },
  changeTime(e){
    this.setData({ time: e.detail.value });
  },
  changeDateTime(e){
    this.setData({ dateTime: e.detail.value });
  },
  changeDateTime1(e) {
    this.setData({ dateTime1: e.detail.value });
  },
  changeDateTimeColumn(e){
    var arr = this.data.dateTime, dateArr = this.data.dateTimeArray;

    arr[e.detail.column] = e.detail.value;
    dateArr[2] = dateTimePicker.getMonthDay(dateArr[0][arr[0]], dateArr[1][arr[1]]);

    this.setData({
      dateTimeArray: dateArr,
      dateTime: arr
    });
  },
  changeDateTimeColumn1(e) {
    var arr = this.data.dateTime1, dateArr = this.data.dateTimeArray1;

    arr[e.detail.column] = e.detail.value;
    dateArr[2] = dateTimePicker.getMonthDay(dateArr[0][arr[0]], dateArr[1][arr[1]]);

    this.setData({ 
      dateTimeArray1: dateArr,
      dateTime1: arr
    });
  }
})

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
}
