picker-view
嵌入页面的滚动选择器
注意:其中只可放置<picker-view-column/>

picker-view-column
仅可放置于<picker-view />

示例代码:
<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, year: date.getFullYear(), 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[1]] }) } })
