Vue3 中未发出 beforeDestroy 生命周期钩子 [英] Lifecycle hook beforeDestroy is not emitted in Vue3

问题描述

我使用vue3 beta 18，发现当我删除一个由v-for中的动态组件渲染的组件时，没有发出beforeDestroy.

I use vue3 beta 18, found that beforeDestroy is not emitted when I remove a component which is rendered by dynamic component in v-for.

既没有被停用，也没有被销毁.

Neither are deactivated, destroyed.

当我从集合windows"中删除该组件时，该组件消失了".

The component is "disappeared", when I remove it from the collection "windows".

<template>
component(v-for="ww in windows" :key="ww.$id" :is="ww.component" v-bind="ww.props")
</template>

推荐答案

在 Vue 3 中，beforeDestroy 和destroy hooks 被替换为 beforeUnmount 和 unmounted https://v3.vuejs.org/api/options-lifecycle-hooks.html#beforeunmount

In Vue 3 beforeDestroy and destroyed hooks are replaced with beforeUnmount and unmounted https://v3.vuejs.org/api/options-lifecycle-hooks.html#beforeunmount
