用vue写了个瀑布流布局，看着还可以

曾经终败给现在 2022-05-08 11:28 207阅读 0赞

### 源博文发布于2018-10-11 (由于收到建议，在vue中v-for的优先级高于v-if的优先级，这意味着`v-if` 将分别重复运行于每个 `v-for` 循环中所以，不推荐v-if和v-for同时使用) ###

**2019-6-1【最新更改的代码】**，并未通过v-if来判断拆分左右两部分布局，而是通过css来达到瀑布流效果，下面为最新代码，可以直接复制使用。

**【原旧的代码】**，是通过v-if = index% == 0  和 v-if = index% == 1 将布局拆分左右两个部分再做浮动(不建议使用)

在学vue的路上，学了些基础，验收一下学习爱的成果。写了个简单的瀑布流布局，当作记录一下学习过程。适合新手们，比较简单易上手，不废话了，上代码。
