这篇文章主要为大家详细介绍了微信小程序日期时间选择器的使用方法,自定义精确到分秒或时段,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
本文实例为大家分享了精确到秒的微信小程序日期时间选择器,供大家参考,具体内容如下
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 }
总结
- 将初始化列表以及初始化默认显示的数组放到dateTimePicker.js,防止页面逻辑太乱,而且可以多处使用;
- 判断是否为闰年,在三木表达式中,必须将能别400整除放在前边,因为或运算只要一个条件满足,就会返回true,不会执行后续表达式;
- switch case的合并方法需要注意格式;
- 如果只需要联动列表更新,二结果展示栏不更新,则在changeDateTimeColumn函数中只更新dateTimeArray的值。
