picker-view
嵌入页面的滚动选择器
注意：其中只可放置<picker-view-column/>组件，其他节点不会显示。
picker-view-column
仅可放置于<picker-view />中，其孩子节点的高度会自动设置成与picker-view的选中框的高度一致
示例代码：
在开发者工具中预览效果
<view><view>{{year}}年{{month}}月{{day}}日</view><picker-view indicator-style="height: 50px;" style="width: 100%; height: 300px;" value="{{value}}" bindchange="bindChange"><picker-view-column><view wx:for="{{years}}" style="line-height: 50px">{{item}}年</view></picker-view-column><picker-view-column><view wx:for="{{months}}" style="line-height: 50px">{{item}}月</view></picker-view-column><picker-view-column><view wx:for="{{days}}" style="line-height: 50px">{{item}}日</view></picker-view-column></picker-view></view>
const date = new Date()const years = []const months = []const days = []
for (let i = 1990; i <= date.getFullYear(); i++) {
years.push(i)
}
for (let i = 1 ; i <= 12; i++) {
months.push(i)
}
for (let i = 1 ; i <= 31; i++) {
days.push(i)
}
Page({
data: {
years: years,
year: date.getFullYear(),
months: months,
month: 2,
days: days,
day: 2,
value: [9999, 1, 1],
},
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]]
})
}
})
Tips
tip: 滚动时在iOS自带振动反馈，可在系统设置 -> 声音与触感 -> 系统触感反馈中关闭总结
value 里面的值为默认值;
案例中只有年月日，如果想参考年月日时分秒，请参考博客[/qq_37022150]
