本文主要為大家詳細(xì)介紹了微信小程式日期時(shí)間選擇器的使用方法，自訂精確到分秒或時(shí)段，具有一定的參考價(jià)值，有興趣的小夥伴們可以參考一下，希望能幫助到大家。

利用微信小程式的picker元件的多列選擇器實(shí)作！

 </view>
 </picker>
</view>

WXSS

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

使用的是三級(jí)連動(dòng)選擇器的樣式，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(){
 // 獲取完整的年月日 時(shí)分秒，以及默認(rèn)顯示的數(shù)組
 var obj = dateTimePicker.dateTimePicker(this.data.startYear, this.data.endYear);
 var obj1 = dateTimePicker.dateTimePicker(this.data.startYear, this.data.endYear);
 // 精確到分的處理，將數(shù)組的秒去掉
 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;月份格式不正確，請(qǐng)重新輸入！&#39;
 }
 return array;
}
function getNewDateArry(){
 // 當(dāng)前時(shí)間的處理
 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) {
 // 返回默認(rèn)顯示的數(shù)組和聯(lián)動(dòng)數(shù)組的聲明
 var dateTime = [], dateTimeArray = [[],[],[],[],[],[]];
 var start = startYear || 1978;
 var end = endYear || 2100;
 // 默認(rèn)開始顯示數(shù)據(jù)
 var defaultDate = date ? [...date.split(&#39; &#39;)[0].split(&#39;-&#39;), ...date.split(&#39; &#39;)[1].split(&#39;:&#39;)] : getNewDateArry();
 // 處理聯(lián)動(dòng)列表數(shù)據(jù)
 /*年月日 時(shí)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
}

總結(jié)

• 將初始化列表以及初始化預(yù)設(shè)顯示的陣列放到dateTimePicker.js，防止頁面邏輯太亂，而且可以多處使用；

• 判斷是否為閏年，在三木表達(dá)式中，必須將能別400整除放在前邊，因?yàn)榛蜻\(yùn)算只要一個(gè)條件滿足，就會(huì)傳回true，不會(huì)執(zhí)行後續(xù)表達(dá)式；

• switch case的合併方法需要注意格式；

• 如果只需要連動(dòng)清單更新，二結(jié)果展示列不更新，則在changeDateTimeColumn函數(shù)中只更新dateTimeArray的值。
