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)

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