昨日,小程序开发者工具又更新啦!这次又推出了一些比较棒的功能,个人觉得这个省市区联动还是比较棒的,特此贴出源码供大家查看~picker-view嵌入页面的滚动选择器属性名类型说明最低版本valueNumberArray数组中的数 ...
嵌入页面的滚动选择器
注意:其中只可放置
组件,其他节点不会显示。
仅可放置于
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:
<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]]
})
}
})
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
