bug:由于此篇博客是在bindcolumnchange事件中做的值的改变处理,因此会出现当你选择时,没有点击确定,直接取消返回后,会发现选择框的值依然改变。 造成原因:这一点就是由于在bindcolumnchange事件做的值改变处理造成。 处理方法:如果需要确定后再改变值,请将bindcolumnchange事件中的处理操作放到bindchange事件中。 感谢:感谢qq_41906890指出的问题!
利用微信小程序的picker组件的多列选择器实现!
<view class="tui-picker-content">
<view class="tui-picker-name">时间选择器(选择时分)</view>
<picker mode="time" value="{{time}}" start="09:00" end="17:30" bindchange="changeTime">
<view class="tui-picker-detail">
午饭时间: {{time}}
</view>
</picker>
</view>
<view class="tui-picker-content">
<view class="tui-picker-name">日期选择器(选择年月日)</view>
<picker mode="date" value="{{date}}" start="2017-10-01" end="2017-10-08" bindchange="changeDate">
<view class="tui-picker-detail">
国庆出游: {{date}}
</view>
</picker>
</view>
<view class="tui-picker-content">
<view class="tui-picker-name">日期时间选择器(精确到秒)</view>
<picker mode="multiSelector" value="{{dateTime}}" bindchange="changeDateTime" bindcolumnchange="changeDateTimeColumn" range="{{dateTimeArray}}">
<view class="tui-picker-detail">
选择日期时间: {{dateTimeArray[0][dateTime[0]]}}-{{dateTimeArray[1][dateTime[1]]}}-{{dateTimeArray[2][dateTime[2]]}} {{dateTimeArray[3][dateTime[3]]}}:{{dateTimeArray[4][dateTime[4]]}}:{{dateTimeArray[5][dateTime[5]]}}
</view>
</picker>
</view>
<view class="tui-picker-content">
<view class="tui-picker-name">日期时间选择器(精确到分)</view>
<picker mode="multiSelector" value="{{dateTime1}}" bindchange="changeDateTime1" bindcolumnchange="changeDateTimeColumn1" range="{{dateTimeArray1}}">
<view class="tui-picker-detail">
选择日期时间: {{dateTimeArray1[0][dateTime1[0]]}}-{{dateTimeArray1[1][dateTime1[1]]}}-{{dateTimeArray1[2][dateTime1[2]]}} {{dateTimeArray1[3][dateTime1[3]]}}:{{dateTimeArray1[4][dateTime1[4]]}}
</view>
</picker>
</view>

使用的是三级联动选择器的样式,所以直接 import 引入!
