//组件component 中的wxml

<picker mode="multiSelector" value="{{dateTime}}" bindcolumnchange="changeDateTimeColumn" bindchange="changeDateTime" range="{{dateTimeArray}}"> <view class="picker" style="{{pickUpTime ? '' : 'color: #8a8a8a'}}"> {{dateTimeArray[0][dateTime[0]]}}-{{dateTimeArray[1][dateTime[1]]}}-{{dateTimeArray[2][dateTime[2]]}} {{dateTimeArray[3][dateTime[3]]}}:{{dateTimeArray[4][dateTime[4]]}} </view></picker>

//组件component 中的js

const dateTimePicker = require('../../utils/dateTimePicker.js');// components/pikerTime/index.jsComponent({ /** * 组件的属性列表 */ properties: { }, /** * 组件的初始数据 */ data: { }, lifetimes: { attached() { this.startTime() } }, /** * 组件的方法列表 */ methods: { startTime() { var obj = dateTimePicker.dateTimePicker(this.data.startYear, this.data.endYear); var lastArray = obj.dateTimeArray.pop(); var lastTime = obj.dateTime.pop(); this.setData({ dateTimeArray: obj.dateTimeArray, dateTime: obj.dateTime }) }, changeDateTime(e) { this.setData({ dateTime: 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 }); } }})
