   <view wx:for="{{pinpaiTishi}}" wx:key="{{xxx}}">         <view wx:if="{{item.name!=null}}" wx:key="{{xxxx}}">         //判断name是否为null          <view class="tr">           <view class="td-left"></view>           <view class="td-right">            <view bindtap="onclickByPinpai" data-name="{{item.name}}" class="tishi">{{item.name}}</view>                绑定的方法        参数值           </view>          </view>         </view>        </view>

<view class="pad10" wx:for="{{twoList}}" wx:key="{{xxx}}">  <view>    {{index+1}}、{{item.name}}  </view>    <!--二次嵌套循环-->  <view wx:for="{{item.XXX}}" wx:for-item="XXXX" wx:key="XXXX">    ----{{XXXX.name}}  </view></view>
