如果只需要日期或者时间用原生的微信组件就可以,但是最近做小程序有个需求,用户需要选择年月日时分秒的日期,完整代码如下:
1、引入js控件
//设置日期的两位数显示 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]; } /** * startYear: 开始的年份,进行年份的范围指定 * endYear: 结束的年份,进行年份的范围指定 * date: 年份日期 * 1、如果不传参数,默认显示当前日期和时间 * 2、如果只需要date参数,将startYear和endYear设置为空字符串 */ 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 } } /** 对数组中的时间信息进行格式化 * dateTimeArray :通过dateTimePicker获取的日期范围数组 * dateTime: 选择的日期数组信息 */ function formatPickerDateTime(dateTimeArray,dateTime) { var obj = dateTimePicker() var format = dateTimeArray[0][dateTime[0]] + '-' + dateTimeArray[1][dateTime[1]] + '-' + dateTimeArray[2][dateTime[2]] + " " + dateTimeArray[3][dateTime[3]] + ':' + dateTimeArray[4][dateTime[4]] + ':' + dateTimeArray[5][dateTime[5]] return format } module.exports = { dateTimePicker: dateTimePicker, getMonthDay: getMonthDay, formatPickerDateTime: formatPickerDateTime }
2、小程序页面代码
<view> <view>日期时间</view> <picker mode="multiSelector" value="{{dateTime}}" bindchange="changeDateTime" range="{{dateTimeArray}}"> <view>{{startT}}</view> </picker> </view>
3、页面JS代码
var dateTimePicker = require('../dateTimePicker.js') Page({ data: { dateTime:'', dateTimeArray:'', startT:'' }, onLoad: function (options) { var start = '2019-04-26 15:26:56' var obj = dateTimePicker.dateTimePicker(2015,2020,start); this.setData({ dateTime: obj.dateTime, dateTimeArray: obj.dateTimeArray }); var startT = dateTimePicker.formatPickerDateTime(this.data.dateTimeArray,this.data.dateTime) this.setData({ startT: startT }) }, //获取时间日期 changeDateTime(e) { this.setData({ dateTime: e.detail.value }) var startT = dateTimePicker.formatPickerDateTime(this.data.dateTimeArray, this.data.dateTime) this.setData({ startT: startT }) }, })
