昨日汰现，小程序開發(fā)者工具又更新啦脖律！這次又推出了一些比較棒的功能，個人覺得這個省市區(qū)聯(lián)動還是比較棒的五垮，特此貼出源碼供大家查看~
picker-view
嵌入頁面的滾動選擇器
注意：其中只可放置
組件辛润，其他節(jié)點不會顯示濒生。
picker-view-column
僅可放置于
中，其孩子節(jié)點的高度會自動設(shè)置成與picker-view的選中框的高度一致
示例代碼：
<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[2]]
})
}
})
picker_view
tip
: 滾動時在iOS自帶振動反饋控乾，可在系統(tǒng)設(shè)置 -> 聲音與觸感 -> 系統(tǒng)觸感反饋中關(guān)閉
