微信小程序Picker自定义日期时间

老规矩:先上效果图,再看源码!

功能:可以自定日期时间的Picker,根据不同的需求做不一样的Picker!

第一步:新建一个js文件:名为dateTimePicker.js,作用是自定义日期时间js工具

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); 秒*/

  dateTimeArray.forEach((current, index) => {
    dateTime.push(current.indexOf(defaultDate[index]));
  });

  return {
    dateTimeArray: dateTimeArray,
    dateTime: dateTime
  }
}
module.exports = {
  dateTimePicker: dateTimePicker,
  getMonthDay: getMonthDay
}

第二步:在相应的模块的js里面引入

var dateTimePicker = require('../../../utils/dateTimePicker.js');

Page({

  /**
   * 页面的初始数据
   */
  data: {
    startYear: 2019,
    endYear: 2019,
    startDateArray:null,
    endDateArray:null,
    startTime:null,
    endTime:null
  },
  bindTypePickerChange: function (e) {
    console.log('picker发送选择改变，携带值为', e.detail.value)
    this.setData({
      typeIndex: e.detail.value
    })
  },
  bindStartDateChange: function (e) {
    this.setData({
      startDate: e.detail.value
    })
  },
  changeEndDateColumn(e) {
   
  },
  changeDateTimeColumn(e) {
    
  },
  bindEndDateChange: function (e) {
    console.log('picker发送选择改变，携带值为', e.detail.value)
    this.setData({
      endDate: e.detail.value
    })
  },
  /**
   * 生命周期函数--监听页面加载
   */
  onLoad: function (options) {
    var obj = dateTimePicker.dateTimePicker(this.data.startYear, this.data.endYear);
    var startDate = this.formatDate(new Date());
    this.setData({
      startDate: obj.dateTime,
      startDateArray: obj.dateTimeArray,
      endDate: obj.dateTime,
      endDateArray: obj.dateTimeArray
    })
  },
  /**
   * 生命周期函数--监听页面初次渲染完成
   */
  onReady: function () {

  },

  /**
   * 生命周期函数--监听页面显示
   */
  onShow: function () {

  },

  /**
   * 生命周期函数--监听页面隐藏
   */
  onHide: function () {

  },

  /**
   * 生命周期函数--监听页面卸载
   */
  onUnload: function () {

  },

  /**
   * 页面相关事件处理函数--监听用户下拉动作
   */
  onPullDownRefresh: function () {

  },

  /**
   * 页面上拉触底事件的处理函数
   */
  onReachBottom: function () {

  },

  /**
   * 用户点击右上角分享
   */
  onShareAppMessage: function () {

  }
})

第三步:在wxml初始化picker

      <picker mode="multiSelector" value="{{startDate}}"  bindchange="bindStartDateChange" bindcolumnchange="changeDateTimeColumn" range="{{startDateArray}}">
        <view class="flex-display font-size-25 padding-30 background-color-white border-bottom">
            <view class="flex-width-1 input-label">开始时间:</view>
            <view class="flex-width-5 flex-display">
              <view class="flex-width-1">
                <input placeholder="请选择" disabled value="{{startDateArray[0][startDate[0]]}}-{{startDateArray[1][startDate[1]]}}-{{startDateArray[2][startDate[2]]}} {{startDateArray[3][startDate[3]]}}:{{startDateArray[4][startDate[4]]}}"/>
              </view>
              <view>
                <image src="../../../images/dayu.png" class="message-image"/>
              </view>
            </view>
        </view>
      </picker>

      <picker mode="multiSelector" value="{{endDate}}"  bindchange="bindEndDateChange" bindcolumnchange="changeEndDateColumn" range="{{endDateArray}}">
        <view class="flex-display font-size-25 padding-30 background-color-white border-bottom">
            <view class="flex-width-1 input-label">结束时间:</view>
            <view class="flex-width-5 flex-display">
              <view class="flex-width-1">
                <input placeholder="请选择" disabled value="{{endDateArray[0][endDate[0]]}}-{{endDateArray[1][endDate[1]]}}-{{endDateArray[2][endDate[2]]}} {{endDateArray[3][endDate[3]]}}:{{endDateArray[4][endDate[4]]}}"/>
              </view>
              <view>
                <image src="../../../images/dayu.png" class="message-image"/>
              </view>
            </view>
        </view>
      </picker>

这就可以了!
