微信小程序时间标签和时间范围的联动

最近忙于一个有关数据管理的微信小程序，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>
      到
      <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>
