当烟雨缭绕、蓑衣低垂的时候,生命如同一曲绵长的旋律,诉说着它独特的故事

事情经过是大佬询问微信小程序首页小程序双行金刚区滚动翻页效果是如何做到的

若你问我,之前也没学习过;但是我会摇人哇!
方式一:
flex-flow: column wrap 实现两行布局加上scroll-view 实现滚动
方式二:
swiper + flex布局(或者grid组件) + js分割数组
取舍
条条大路通罗马,我们只需要选择一合适自己的一条,方式一内心是拒绝的,因为scroll-view的滚动需要我们去计算
而方式二只要js数组分割一个难点而已
思路
模拟12条数据,使用js将数据分割8个一组,先循环swiper,在循环一次里面的金刚区
代码
为了方便实用uni-app做案例,其实核心只有js分割
