更新時(shí)間：2018年12月28日 11:08:57 作者：未名胡

這篇文章主要介紹了微信小程序時(shí)間控件picker view的使用方法，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了微信小程序時(shí)間控件的具體實(shí)現(xiàn)代碼，供大家參考，具體內(nèi)容如下

在原來基礎(chǔ)上改了點(diǎn)，由于項(xiàng)目需要按照功能需求自己在原有的組件上改寫的選擇日期時(shí)間插件，但后來這個(gè)功能取消，所以整理下寫下來

wxml:

<view class="time_screens">
 <view style="text-align:center;color:#45BCE8">{{year}}-{{month}}-{{day}} {{hour}}:{{minute}}<label style="float:right;margin-right:10px;">確定</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">時(shí)</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
  })
 },
 
})
