形如上方代码，如何循环 ？

Answer 1

我是用两层循环做的

<view class='exh-list'>
    <block wx:for="{{2}}" wx:for-index="i" wx:for-item="item_i" wx:for-key="key_i">
        <view class='row'>
            <block wx:for="{{3}}" wx:for-index="j" wx:for-item="item_j" wx:for-key="key_j">
                <view class='item' bindtap='showService' data-index='{{i*3+j+5}}'>
                     <image src='../../public/images/ad01.jpg' mode='widthFix' class='head-img'></image> 
                    <text>rs000{{i*3+j+1}}</text>
                </view>
            </block>
        </view>
    </block>
</view>

结果
