精确到秒的微信小程序日期时间选择器

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>

使用的是三级联动选择器的样式，所以直接 import 引入！

var dateTimePicker = require(&#39;../../utils/dateTimePicker.js&#39;);

Page({
 data: {
 date: &#39;2018-10-01&#39;,
 time: &#39;12:00&#39;,
 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 ? &#39;0&#39; + param : &#39;&#39; + 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 &#39;01&#39;:
 case &#39;03&#39;:
 case &#39;05&#39;:
 case &#39;07&#39;:
 case &#39;08&#39;:
 case &#39;10&#39;:
 case &#39;12&#39;:
  array = getLoopArray(1, 31)
  break;
 case &#39;04&#39;:
 case &#39;06&#39;:
 case &#39;09&#39;:
 case &#39;11&#39;:
  array = getLoopArray(1, 30)
  break;
 case &#39;02&#39;:
  array = flag ? getLoopArray(1, 29) : getLoopArray(1, 28)
  break;
 default:
  array = &#39;月份格式不正确，请重新输入！&#39;
 }
 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(&#39; &#39;)[0].split(&#39;-&#39;), ...date.split(&#39; &#39;)[1].split(&#39;:&#39;)] : 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
}
