本文实例为大家分享了微信小程序时间控件的具体实现代码，供大家参考，具体内容如下

在原来基础上改了点，由于项目需要按照功能需求自己在原有的组件上改写的选择日期时间插件，但后来这个功能取消，所以整理下写下来

wxml:

<view class="time_screens">
 <view style="text-align:center;color:#45BCE8">{{year}}-{{month}}-{{day}} {{hour}}:{{minute}}<label style="float:right;margin-right:10px;">确定</label></view>
 <view style="border-top:1px solid #45BCE8;height:25px;font-size:14px;">
 <view class="time-title">年</view>
 <view class="time-title">月</view>
 <view class="time-title">日</view>
 <view class="time-title">时</view>
 <view class="time-title">分</view>
 </view>
 <picker-view indicator-style="height: 50px;" style="width: 100%; height: 300px;" value="{{value}}" bindchange="bindChange">
  <picker-view-column class="picker-text">
   <view wx:for="{{years}}" style="line-height: 50px">{{item}}</view>
  </picker-view-column>
  <picker-view-column class="picker-text">
   <view wx:for="{{months}}" style="line-height: 50px">{{item}}</view>
  </picker-view-column>
  <picker-view-column class="picker-text">
   <view wx:for="{{days}}" style="line-height: 50px">{{item}}</view>
  </picker-view-column>
   <picker-view-column class="picker-text">
   <view wx:for="{{hours}}" style="line-height: 50px">{{item}}</view>
  </picker-view-column>
   <picker-view-column class="picker-text">
   <view wx:for="{{minutes}}" style="line-height: 50px">{{item}}</view>
  </picker-view-column>
 </picker-view>
</view>

wxss:

.time-title{
 float:left;width:20%;text-align:center;color:#45BCE8
}
.picker-text{
 text-align:center;
}
/*mask*/
.time_screens {
 
 width: 100%;
 
 position: fixed;
bottom: 0;
 left: 0;
 z-index: 1000;
 opacity: 0.5;
 overflow: hidden;
}

js：

const date = new Date()
const years = []
const months = []
const days = []
const hours = []
const minutes = []
var thisMon = date.getMonth();
var thisDay = date.getDate();
 
for (let i = 2017; i <= date.getFullYear()+1; i++) {
 years.push(i)
}
 
for (let i = date.getMonth(); i <= 11; i++) {
 var k = i;
 if (0 <= i && i < 9) {
  k = "0" + (i+1);
 }else{
  k = (i + 1);
 }
 months.push(k)
}
if (0 <= thisMon && thisMon<9){
 thisMon = "0" + (thisMon + 1);
}else{
 thisMon = (thisMon + 1);
}
if (0 <= thisDay && thisDay<10){
 thisDay ="0"+thisDay;
}
 
var totalDay = mGetDate(date.getFullYear(), thisMon); 
for (let i = 1; i <= 31; i++) {
 var k = i;
 if (0 <= i && i < 10) {
  k = "0" + i
 }
 days.push(k)
}
 
for (let i = 0; i <= 23; i++) {
 var k=i;
 if(0<=i&&i<10){
  k="0"+i
 }
 hours.push(k)
}
for (let i = 0; i <= 59; i++) {
 var k = i;
 if (0 <= i && i < 10) {
  k = "0" + i
 }
 minutes.push(k)
}
function mGetDate(year, month) {
 var d = new Date(year, month, 0);
 return d.getDate();
}
Page({
 data: {
  years: years,
  year: date.getFullYear(),
  months: months,
  month: thisMon,
  days: days,
  day: thisDay,
  value: [1,thisMon-1,thisDay-1,0,0],
  hours: hours,
  hour: "00",
  minutes: minutes,
  minute: "00",
 },
 bindChange: function (e) {
  const val = e.detail.value
  this.setData({
   year: this.data.years[val[0]],
   month: this.data.months[val[1]],
   day: this.data.days[val[2]],
   hour: this.data.hours[val[3]],
   minute: this.data.minutes[val[4]],
  })
  var totalDay = mGetDate(this.data.year, this.data.month); 
  var changeDate=[];
  for (let i = 1; i <= totalDay; i++) {
   var k = i;
   if (0 <= i && i < 10) {
    k = "0" + i
   }
   changeDate.push(k)
  }
  this.setData({
   days: changeDate
  })
 },
 
})
