微信小程序 for循环嵌套怎么取值

外层循环正常嵌套，内层循环嵌套的时候，把item.swiper_buy作为数组循环wx:for="{{item.swiper_buy}}"，然后给item重新命名wx:for-item="cell"，内部循环的时候，就是{{cell.属性}}

 

   
     
       
         
         
            嘻哈帮街舞.{{item.card_name}}
            {{item.card_use}}
            {{item.card_region}}
         
       
       
         
           
             
                ¥{{cell.buy_price}}
                {{cell.card_species}}
             
              {{cell.buy_send}}
