微信小程序時間標簽與范圍聯動設計實現

微信小程序時間標簽與范圍聯動設計實現？最近忙于一個有關數據管理的微信小程序開發，遇到了上圖情況，雖然很簡單，還是整理一下。若有錯誤，請廣大朋友們指正。

使用微信小程序組件radio-group、picker，用wxss對radio按照需求進行重構，picker里邊的start和end時間是根據radio來顯示的。將start、end時間放在data里，radio發生改變時，改變data中的時間。當picker中的值發生改變時，如果時間范圍已經超出了radio中的范圍，需要對radio的顯示進行實時修改。

話不多說，接下來上代碼。

index.wxml

<view class="con_screen">
<text class="cons_ti">日期范圍</text>
<!-- 單選時間 -->
<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>
<!-- 時間段 -->
<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>
