关键词:vue 内置组件
在 Vue 中,有一些内置组件,主要包括以下几个:
一、<component>动态组件
<component>
作用:用于根据条件动态地渲染不同的组件。
使用方法:
<template> <div> <component :is="currentComponent"></component> <button @click="toggleComponent">Toggle Component</button> </div> </template> <script setup> import ComponentA from "./ComponentA.vue"; import ComponentB from "./ComponentB.vue"; let currentComponent = ComponentA; const toggleComponent = () => { currentComponent = currentComponent === ComponentA ? ComponentB : ComponentA; }; </script>
二、<transition>过渡组件
<transition>
作用:为元素或组件的插入、更新和移除添加过渡效果。
<template> <div> <transition name="fade"> <p v-if="show">Hello World</p> </transition> <button @click="toggleShow">Toggle</button> </div> </template> <script setup> import { ref } from "vue"; const show = ref(true); const toggleShow = () => { show.value = !show.value; }; </script> <style> .fade-enter-active, .fade-leave-active { transition: opacity 0.5s; } .fade-enter-from, .fade-leave-to { opacity: 0; } </style>
三、<teleport>传送门组件
<teleport>
作用:将一个组件的模板内容渲染到指定的 DOM 节点位置,而不是在组件自身的位置。
<template> <div> <teleport to="body"> <div class="modal">This is a modal content.</div> </teleport> </div> </template> <style> .modal { position: fixed; top: 50%; left: 50%; transform: translate(-50%, -50%); background-color: white; padding: 20px; border: 1px solid #ccc; } </style>
四、<keep-alive>缓存组件
<keep-alive>
作用:在组件切换时缓存不活动的组件实例,避免重复渲染,提高性能。
<template> <div> <keep-alive> <component :is="currentComponent"></component> </keep-alive> <button @click="toggleComponent">Toggle Component</button> </div> </template> <script setup> import ComponentA from "./ComponentA.vue"; import ComponentB from "./ComponentB.vue"; let currentComponent = ComponentA; const toggleComponent = () => { currentComponent = currentComponent === ComponentA ? ComponentB : ComponentA; }; </script>
