uniapp微信小程序 选择日期时间

一。根据需要点击选择时间日期，效果如下图：

（1）新建一个dateTimePicker.js文件

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 年月日时分秒

  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;

 //处理传过来的字符串转化为数组

 let dataArr = date.split(" ")[0].split('/')

 let time = date.split(" ")[1].split(':')

  // 默认开始显示数据 如果把自定义值传过来的话就使用自定义时间 否则用当前时间  ...dataArr数组解构

  var defaultDate = date ? [...dataArr, ...time] : 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);

 //遍历dateTimeArray数组

  dateTimeArray.forEach((current,index) =>{

  //匹配defaultDate[index]值在current数组中的位置

    dateTime.push(current.indexOf(defaultDate[index]))

  });

  return {

    dateTimeArray: dateTimeArray,

    dateTime: dateTime

  }

}

module.exports = {

  dateTimePicker: dateTimePicker,

  getMonthDay: getMonthDay

}

（2）需要用到的页面中

<view class="warning-form-item">

      <view class="warning-title">上门时间</view>

      <picker class="warning-input" mode="multiSelector" :range="dateTimeArray" v-model="dateTime" @change="change" @columnchange="columnchange">

          <view class="inp-box">

               <input type="text" disabled="true" v-model="upTower" placeholder="请选择时间" placeholder-class="inputPlace" />

          </view>

      </picker>

</view>

（3）引入js文件，并调取方法

const dateTimePicker = require('@/utils/dateTimePicker.js')

onLoad(){

　　let date = new Date(),

    Y = date.getFullYear() + '/',

    M = (date.getMonth() + 1 < 10 ? '0' + (date.getMonth() + 1) : date.getMonth() + 1) + '/',

    D = date.getDate() + ' ',

    h = '10' + ':',

   //   m = date.getMinutes() + ':',

    // s = date.getSeconds()

    m = '00'+ ':',

    s = '00';

    let arr = Y+M+D + h + m +s

    let obj = dateTimePicker.dateTimePicker(this.startYear, this.endYear,arr)

    this.dateTimeArray = obj.dateTimeArray

    this.dateTime = obj.dateTime

}
method:{

//时间格式化
withData(param){
　　return param < 10 ? '0' + param : '' + param;
},
change(e){
　　let value = []
　　e.detail.value.forEach((val,index) => {
　　　　value.push(this.withData(val))
　　})
　　console.log(value,'value')
　　let m = Number(value[1])+1 ;
　　let d = Number(value[2])+1 ;
　　if(m<10) m = '0'+m
　　if(d<10) d = '0'+d

　　let dateArray = "20" + value[0] + "-" + m + "-" + d + " " + value[3] + ":" + value[4]+ ":" + value[5]
　　this.upTower = dateArray
　　console.log(this.upTower,'this.upTower')
　　this.form.visitTime = dateArray
},
columnchange(e){
　　let dateArr = this.dateTimeArray
　　let arr = this.dateTime
　　//滑动所在列的数据并对其值进行更新
　　arr[e.detail.column] = e.detail.value
　　//更新展示月份对应的天数（28 or 29 or 30 or 31）
　　dateArr[2] = dateTimePicker.getMonthDay(dateArr[0][arr[0]], dateArr[1][arr[1]])
　　//最后把最新的数值赋值到dateTimeArray
　　this.dateTimeArray = dateArr
　　this.dateTime = arr
},

}

二。根据需要点击选择日期，效果如下：

<view class="warning-form-item">

    <view class="warning-title">选择时间</view>

    <view class="uni-list-cell-db warning-inputs">

        <picker mode="date" :value="date" :start="startDate" :end="endDate"  @cancel="cancel" @change="bindDateChange">

              <view class="pick_item">

                   <view :class="is_writez? 'uni-input':'clo-color' ">{{unitData}}</view>

              </view>

        </picker>

    </view>

    <image class="per-shimg" src="../../../static/images/more_n.png" mode="">

</view>

bindDateChange(e) {

    this.is_writez = true

    this.date = e.detail.value

    this.unitData = this.date

    this.visitor.checkInTime = this.unitData

},

cancel(){

    this.unitData = "选择时间"

    this.date = ''

},
