cet6cat_front's Issues

使用v-for绑定key要注意

当我们在使用v-for进行渲染时,尽可能使用渲染元素自身属性的id给渲染的元素绑定一个key值,这样在当前渲染元素的DOM结构发生变化时,能够单独响应该元素而不触发所有元素的渲染。

读一下这篇

beforeRouteUpdate无效

这个钩子在当前路由改变,但是该组件被复用时调用。
对于一个带有动态参数的路径 /good/:id,在 /good/1 和 /good/2 之间跳转的时候,由于会渲染同样的good组件,因此组件实例会被复用。而这个钩子就会在这个情况下被调用。
参考安静的久久的cnblog

webpack-dev-server问题

Github上提示更新到3.1.11,可是直接更新它的话,整个项目都没法运行了。但是其它的依赖不知道哪个要跟着更新,更新到哪个版本。
