微信小程序–多种类型日期选择器(年月、月日…)
在业务开发的过程中,有许多对picker选择器的使用场景,根据开发需要列出了几种常见的类型,可供大家共同参考、学习

时间选择器(年月日)
效果图:

wxml:

<picker mode="date" header-text="选择时间"  value="{{date}}" bindchange="bindDateChange">  <view class="font30">    <text class="color3">填报时间:</text>    <text class="color6">{{date}}</text>    <text class="timeIcon">▼</text>  </view></picker>

js

data:{  date:'2021-01-01',},bindDateChange: function(e) {  console.log('picker发送选择改变,携带值为', e.detail.value)  this.setData({    date: e.detail.value  })},

wxss

.font30{  font-size: 30rpx;}.color3{  color: #333;}.color6{  color: #666;}.timeIcon{  color:#666;  font-size:18rpx;  margin-left: 5rpx;}

时间选择器(年月)

效果图:

wxml:

<picker mode="date" header-text="选择时间" fields="month" value="{{date}}" bindchange="bindDateChange">  <view class="font30">    <text class="color3">填报时间:</text>    <text class="color6">{{date}}</text>    <text class="timeIcon">▼</text>  </view></picker>

js

data:{  date:'2021-01',},bindDateChange: function(e) {  console.log('picker发送选择改变,携带值为', e.detail.value)  this.setData({    date: e.detail.value  })},

wxss

.font30{  font-size: 30rpx;}.color3{  color: #333;}.color6{  color: #666;}.timeIcon{  color:#666;  font-size:18rpx;  margin-left: 5rpx;}

时间选择器(年)

wxml:

<picker mode="date" header-text="选择时间" fields="year" value="{{date}}" bindchange="bindDateChange">  <view class="font30">    <text class="color3">填报时间:</text>    <text class="color6">{{date}}</text>    <text class="timeIcon">▼</text>  </view></picker>

js

data:{  date:'2021',},bindDateChange: function(e) {  console.log('picker发送选择改变,携带值为', e.detail.value)  this.setData({    date: e.detail.value  })},

wxss

.font30{  font-size: 30rpx;}.color3{  color: #333;}.color6{  color: #666;}.timeIcon{  color:#666;  font-size:18rpx;  margin-left: 5rpx;}

这个官方没有给案例 只能自己自定义一个component组件(datePicker)

datePicker.wxml:

<view class='modal-mask' wx:if="{{ showDatePickerPlus }}" bindtap='closeDatePickerPlus'></view><view class='datepicker' wx:if="{{ showDatePickerPlus }}" animation="{{animationData}}">  <view class='datepicker-header'>    <view class='datepicker-header-left'  bindtap='closeDatePickerPlus'>取消</view>    <view class='datepicker-header-right' bindtap='submitSelectDate'>确定</view>  </view>  <view class='datepicker-content'>    <picker-view value="{{glDateNoYearMutiIndex}}" bindchange="bindDateGlNoYear">      <picker-view-column class="picker-view-column">        <view wx:for="{{glMonthsNoYear}}" wx:key="index">{{item}}月</view>      </picker-view-column>      <picker-view-column class="picker-view-column">        <view wx:for="{{glDaysNoYear}}" wx:key="index">{{item}}日</view>      </picker-view-column>    </picker-view>  </view></view>
