微信小程序时间标签与范围联动设计实现？最近忙于一个有关数据管理的微信小程序开发，遇到了上图情况，虽然很简单，还是整理一下。若有错误，请广大朋友们指正。
使用微信小程序组件radio-group、picker，用wxss对radio按照需求进行重构，picker里边的start和end时间是根据radio来显示的。将start、end时间放在data里，radio发生改变时，改变data中的时间。当picker中的值发生改变时，如果时间范围已经超出了radio中的范围，需要对radio的显示进行实时修改。
话不多说，接下来上代码。
index.wxml
<view class="con_screen"> <text class="cons_ti">日期范围</text> <!-- 单选时间 --> <radio-group class="radio-group" bindchange="radioCheckedChange"> <block > <label class="cons_radio {{radioCheckVal==1?‘active‘:‘‘}}" > <radio value="1" hidden="true"/> <text>今日</text> </label> <label class="cons_radio {{radioCheckVal==4?‘active‘:‘‘}}" > <radio value="4" hidden="true" /> <text>近7日</text> </label> <label class="cons_radio {{radioCheckVal==6?‘active‘:‘‘}}" > <radio value="6" hidden="true"/> <text>近30日</text> </label> </block> </radio-group> <!-- 时间段 --> <view class="picker_group"> <picker mode="date" value="{{date}}" start="2015-09-01" end="{{date2}}" bindchange="bindDateChange"> <view class="picker"> {{date}} <image src="../../image/home_zsr_icon.png"></image> </view> </picker> <picker mode="date" value="{{date2}}" start="{{date}}" end="2018-01-24" bindchange="bindDateChange2"> <view class="picker"> {{date2}} <image src="../../image/home_zsr_icon.png"></image> </view> </picker> </view> </view>
