微信小程式 for迴圈巢狀怎麼取值
外層迴圈正常巢狀，內層迴圈巢狀的時候，把item.swiper_buy作為陣列迴圈wx:for="{{item.swiper_buy}}"，然後給item重新命名wx:for-item="cell"，內部迴圈的時候，就是{{cell.屬性}}
<block wx:for="{{swiper_object}}" wx:key="index">
<swiper-item>
<view class='swiper_in'>
<view class='head_img'>
<image src="{{item.head_img}}"></image>
<view class='head_in'>
<view class='card_name'>嘻哈幫街舞.{{item.card_name}}</view>
<view class="card_i">{{item.card_use}}</view>
<view class='use_region'>{{item.card_region}}</view>
</view>
</view>
<view class='buy_list'>
<block wx:for="{{item.swiper_buy}}" wx:for-item="cell" wx:key="index">
<view class="buy_item {{num==index?'current':''}}" data-index="{{index}}" catchtap='switchTab'>
<view class='buy_price'>
<view class='card_price'>¥{{cell.buy_price}}</view>
<view class='nk_species'>{{cell.card_species}}</view>
</view>
<view class='buy_zs'>{{cell.buy_send}}</view>
</view>
</block>
</view>
</view>
</swiper-item>
