# 练习 7:composable 和异步状态
|
||||
|
||||
## 目标
|
||||
|
||||
学会把可复用逻辑抽成 composable,并管理 loading / error / data。
|
||||
|
||||
## 你要练什么
|
||||
|
||||
- composable
|
||||
- `ref`
|
||||
- 异步状态
|
||||
- `loading`
|
||||
- `error`
|
||||
|
||||
## 任务
|
||||
|
||||
- 把课程请求逻辑抽成 `useCourses`
|
||||
- 页面加载时调用它
|
||||
- 显示 loading
|
||||
- 请求成功后渲染列表
|
||||
- 请求失败时显示错误信息

# 练习 11:before 系列生命周期和 expose
|
||||
|
||||
## 目标
|
||||
|
||||
学会在组合式 API 中使用 before 系列生命周期,并理解子组件如何有选择地暴露能力给父组件。
|
||||
|
||||
## 你要练什么
|
||||
|
||||
- `onBeforeMount`
|
||||
- `onBeforeUpdate`
|
||||
- `onBeforeUnmount`
|
||||
- `expose`
|
||||
|
||||
## 任务
|
||||
|
||||
- 在不同生命周期里输出日志
|
||||
- 父组件通过模板 `ref` 获取子组件实例
|
||||
- 子组件通过 `expose` 暴露一个 `focusInput` 方法
|
||||
- 父组件点击按钮后调用这个暴露出来的方法
|
||||

||||

# 练习 13:script setup、defineProps、defineEmits、defineExpose
|
||||
|
||||
## 目标
|
||||
|
||||
补上 Vue3 在工程化单文件组件里的核心宏语法。
|
||||
|
||||
## 你要练什么
|
||||
|
||||
- `<script setup>`
|
||||
- `defineProps`
|
||||
- `defineEmits`
|
||||
- `defineExpose`
|
||||
|
||||
## 说明
|
||||
|
||||
这一题不是浏览器 CDN 练习,而是单文件组件语法练习,需要放在 `Vite + Vue3` 之类的工程里使用。
|
||||
|
||||
## 任务
|
||||
|
||||
- 给子组件定义 `title` 和 `finished` 两个 props
|
||||
- 定义 `toggle` 事件并在按钮点击时触发
|
||||
- 暴露一个 `focusAction` 方法给父组件调用

# Vue3(组合式 API + 响应式原理)
|
||||
|
||||
你的学习文档里这一章的定位是 `Vue3(组合式API + 响应式原理)`。这一章我按这个方向来拆,不再重复 Vue2 的 Options API 主线,而是重点转到 Vue3 的组合式写法和响应式思维。
|
||||
|
||||
## 学完后你应该掌握
|
||||
|
||||
- Vue3 和 Vue2 的核心差异
|
||||
- `createApp`
|
||||
- `setup()`
|
||||
- `ref`
|
||||
- `reactive`
|
||||
- `toRef`
|
||||
- `toRefs`
|
||||
- `readonly`
|
||||
- `computed`
|
||||
- `watch`
|
||||
- `watchEffect`
|
||||
- `nextTick`
|
||||
- 组合式 API 生命周期
|
||||
- 模板 `ref`
|
||||
- `props` 和 `emit`
|
||||
- 组件 `v-model`
|
||||
- `slot`
|
||||
- `provide` / `inject`
|
||||
- `expose`
|
||||
- composable 的基本抽离方式
|
||||
- `script setup`
|
||||
- `defineProps`
|
||||
- `defineEmits`
|
||||
- `defineExpose`
|
||||
- `Teleport`
|
||||
- `Suspense`
|
||||
- `Transition`
|
||||
- 如何用 Vue3 写一个小型管理面板
|
||||
|
||||
## 这一章在解决什么
|
||||
|
||||
Vue2 更强调“选项式组织”。
|
||||
|
||||
Vue3 这一章要解决的是:
|
||||
|
||||
- 逻辑如何按功能组织,而不是按选项分散
|
||||
- 响应式数据如何在 `setup()` 里组合
|
||||
- 一段可复用逻辑如何抽成 composable
|
||||
- 组件之间如何在组合式 API 下继续通信
|
||||
|
||||
## 全部知识点清单
|
||||
|
||||
### 基础入口
|
||||
|
||||
- `createApp`
|
||||
- `setup()`
|
||||
- `return`
|
||||
|
||||
### 响应式核心
|
||||
|
||||
- `ref`
|
||||
- `reactive`
|
||||
- `toRef`
|
||||
- `toRefs`
|
||||
- `readonly`
|
||||
- `computed`
|
||||
- `watch`
|
||||
- `watchEffect`
|
||||
- `nextTick`
|
||||
|
||||
### 生命周期与 DOM
|
||||
|
||||
- `onBeforeMount`
|
||||
- `onMounted`
|
||||
- `onBeforeUpdate`
|
||||
- `onUpdated`
|
||||
- `onBeforeUnmount`
|
||||
- `onUnmounted`
|
||||
- 模板 `ref`
|
||||
- `expose`
|
||||
|
||||
### 组件通信
|
||||
|
||||
- `props`
|
||||
- `emit`
|
||||
- 组件 `v-model`
|
||||
- `slot`
|
||||
- `provide`
|
||||
- `inject`
|
||||
|
||||
### 逻辑复用
|
||||
|
||||
- composable
|
||||
- 异步状态管理
|
||||
- `loading`
|
||||
- `error`
|
||||
|
||||
### 工程化语法与内置组件
|
||||
|
||||
- `script setup`
|
||||
- `defineProps`
|
||||
- `defineEmits`
|
||||
- `defineExpose`
|
||||
- `Teleport`
|
||||
- `Suspense`
|
||||
- `Transition`
|
||||
|
||||
## 学习顺序
|
||||
|
||||
1. `createApp`、`setup()` 和 `ref`
|
||||
2. `reactive` 和 `computed`
|
||||
3. `watch` 和 `watchEffect`
|
||||
4. 生命周期和模板 `ref`
|
||||
5. `props` 和 `emit`
|
||||
6. `slot` 与 `provide` / `inject`
|
||||
7. composable 与异步状态
|
||||
8. `toRefs`、`readonly` 等响应式辅助工具
|
||||
9. `nextTick` 和组件 `v-model`
|
||||
10. before 系列生命周期与 `expose`
|
||||
11. `Teleport`、`Suspense`、`Transition`
|
||||
12. `script setup` 宏
|
||||

## 说明
|

|
||||
- 这一章只提供 `starter`,不提供 `answer`
|

- 为了降低门槛,练习使用浏览器 CDN 版本的 Vue3
|
||||
- `13-script-setup-macros` 是 SFC 语法练习,文件是 `.vue` starter,不是直接双击运行的 HTML
|
||||
- 如果后面你要把这一章升级成 `Vite + Vue3`,我可以再继续补工程化版本
