此外,defineAsyncComponent 还允许你定义加载状态、错误状态等。 示例: import { defineAsyncComponent } from 'vue' const AsyncComponent = defineAsyncComponent(() => import('./views/AsyncComponent.vue') ) const routes = [ { path: '/async-component', name: 'AsyncComponent', component: Async...
1. 什么是Vue 3的动态import? 动态import是一种语法,允许你在JavaScript中异步加载模块。在Vue 3中,这可以用于按需加载组件或JavaScript文件,以减少初始加载时间并提高应用性能。 2. Vue 3中使用动态import的语法示例 动态加载组件 javascript import { defineAsyncComponent } from 'vue'; const AsyncComp = define...
Vue.js 提供了import()函数和defineAsyncComponent方法来实现这一点。 import { defineAsyncComponent } from 'vue'; export default { components: { // 动态引入子组件 ChildComponent: defineAsyncComponent(() => import('./ChildComponent.vue') ) } } 动态引入子组件有助于优化性能,特别是在大型应用中...
import TheComponent from "./components/TheComponent.vue"; const AsyncComponent = defineAsyncComponent(() => import("./components/AsyncComponent.vue") ); console.log("Equivalent to created hook"); onMounted(() => { console.log("Mounted hook called"); }); const enabled = ref(true); const...
在Vue3中，通过import动态加载组件并优雅地实现页面渲染与数据解耦，可以采取以下方案：1. 使用defineAsyncComponent实现异步组件加载： 优势：Vue3的defineAsyncComponent API允许你定义一个异步加载的组件，而无需手动处理Promise。这简化了动态组件的引入和渲染过程。 实现方式：在需要动态加载组件的地方...
