效果图如下所示
这里做的比较简陋，就花了一点时间实现了翻牌抽奖效果,提供思路
.wxml
<view class="button" bindtap="again">重新翻牌</view>
<view class="curin-index">
<view bindtap="{{whether?'':'tamin'}}" wx:for="{{9}}" wx:key="index" data-index="{{index+1}}" class="currin {{really == index+1?'animt':''}} {{really != index+1 && surplus?'animt':''}} {{really == ''?'cinton'+(index+1):''}}" >
{{really == index+1?flop:''}}{{really != index+1 && really != ''?biutin:''}}{{really == ''?'点击翻牌':''}}
</view>
