20 Vue3中使用v-for遍历普通数组
概述
使用v-for遍历普通数组在真实开发中还是比较常见的。
基本用法
我们创建src/components/Demo20.vue，代码如下：
<script setup>
const tags = ["JavaScript", "Vue3", "前端"]
script>
<template>
<div>
<ul>
<li v-for="(tag,index) in tags" :key="index">{{ tag}}li>
ul>
div>
template>
接着，我们修改src/App.vue：
<script setup>
import Demo from "./components/Demo20.vue"
script>
<template>
<h1>【Python私教】使用Vue3进行前端开发h1>
<hr>
<div class="container">
<demo/>
div>
template>
然后，我们浏览器访问：http://localhost:5173/
