<view class="curriculum_body_view" >
 <block wx:for="{{curriculum_body}}" wx:key="*this" wx:if="{{curriculum_body.length>1}}">
  <navigator class="curriculum_body" url="/pages/product/product?id={{item.id}}">
   <image src="{{item.curriculum_body_img}}"></image>
   <view class="curriculum_body_text">

     <block wx:if="{{item.curriculum_body_prices}}">
      <view class="curriculum_body_price">
       <text>￥{{item.curriculum_body_prices}}</text>
       <text>￥{{item.curriculum_body_price}}</text>

     <block wx:else>
      <view class="curriculum_body_price">
       <text>￥{{item.curriculum_body_price}}</text>

     </block>
    </view>
   </navigator>
 </block>
 <block wx:else>
  <image src="/image/common/nullbody.png"></image>
 </block>
