wxml代码如下
<view wx:for="{{subinfo}}" wx:for-item="sub" wx:for-index="ai">
<view class="subname">
{{sub}}
</view>
<view wx:for="{{sub}}" wx:for-item="aitems" wx:for-index="bi">
{{aitems}}
</view>
</view>
js中data如下
data：{
subinfo:["语文","数学","英语","政治"]
语文：["1","2"]
数学：["3","4"]
英语：["5","6"]
政治：["7","8"]
}

以此类推
<view wx:for="{{subinfo}}" wx:for-item="sub" wx:for-index="ai"> <view class="subname"> {{sub.title}} </view> <view wx:for="{{sub.arr}}" wx:for-item="aitems" wx:for-index="bi"> {{aitems}} </view> </view> data：{ subinfo:[ { title:'语文：', arr:["1","2"] }, { title:'数学：', arr:["1","2"] } ] }
