WXML

       <view class="li" wx:for="{{products}}" wx:key="item">
          <image src="{{item.Images.File[0]}}" class="img"></image>
          <view class="grp">
          	<view class="title">{{item.Name}}</view>
            <view class="types mb15">
              <view class="item" wx:for="{{item.ProductClassify}}" wx:for-item="classify" wx:key="">{{classify.Name}}</view>
              <view class="item" wx:if="{{item.ProductSpecs != null}}">{{item.ProductSpecs.length}}个规格</view>
            </view>
            
          </view>
       </view>

关键点：在内循环中，需要使用wx:for-item属性。
