目录结构
批量引入组件
例如:src/views/oss/components/customComponents.ts
import { ref, defineAsyncComponent, markRaw } from 'vue';
const modules = import.meta.glob('./*.vue');
//这告诉 TypeScript,components.value 是一个键为字符串、值为 defineAsyncComponent 返回类型的对象。
const components = ref<Record<string, ReturnType<typeof defineAsyncComponent>>>({});
Object.entries(modules).forEach(([path, asyncCom]) => {
const name = path.replace(/\.\/(.*)\.vue/, '$1');
components.value[name] = markRaw(defineAsyncComponent(asyncCom));
});
export default components
动态使用组件
<template>
<div v-for="(item, index) in componentList" :key="index">
<component :is="customComponents[item]"></component>
</div>
</template>
<script setup name="Oss" lang="ts">
import customComponents from "./components/customComponents"
const componentList: any = ref(['comp1' ,'comp-test' ,'Comp2' ,'CompTest2']);
</script>
或者单个使用
<template>
<component :is="customComponents['comp1']"></component>
<component :is="customComponents['Comp2']"></component>
<component :is="customComponents['comp-test']"></component>
<component :is="customComponents['CompTest2']"></component>
</template>
<script setup name="Oss" lang="ts">
import customComponents from "./components/customComponents"
</script>
错误使用
注意:封装的批量方法仅仅只作用于批量引入组件,并未将其注册为全局组件,所以不能将其直接以组件形式使用
<template>
<comp1 />
<Comp2 />
<comp-test />
<CompTest2 />
</template>
控制台会报出以下警告
index.vue:370 [Vue warn]: Failed to resolve component: comp1
If this is a native custom element, make sure to exclude it from component resolution via compilerOptions.isCustomElement.
