index.wxml

<view>
  <block wx:for="{{data}}" wx-key="index" class="list_top">
    <view data-index="{{index}}" class="list_one {{index==currentIndex?'active':''}}" bindtap="handtab">{{item.name}}
    </view>
  </block>
  <block wx:for="{{shopList}}" wx:key="index">
    <view class="shopList_box" bindtap="handDetail" data-id="{{item.goods_id}}" wx:if="{{status==0}}">
    <!-- 在wxml中使用wx:if status == 0来改变tab切换下面的部分显示与隐藏 -->
      <view class="shopList_left">
        <image class="productpic" src="{{item.goods_big_logo}}"></image>
      </view>
      <view class="shopList_right"> <text class="right">{{item.goods_name}}</text>
        <text class="price">￥{{item.goods_price}}</text>
      </view>
    </view>
  </block>
  <block>
  status==1的情况
    <view wx:if="{{status==1}}">2</view>
