vue v-for 只循环前两个数组

本篇博客主要介绍如何用vue遍历js文件中的数组和对象

index.html

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>vue</title>
	<link rel="stylesheet" href="style.css">
	<script src="https://cdn.jsdelivr.net/npm/vue"></script>

</head>
<body>
	<!--vue-app是根容器-->
	<div id="vue-app">
	<h1>v-for 循环</h1>
	<!-- 数组下标 -->
	<!-- 
	{{characters[0]}}
	{{characters[1]}}
	{{characters[2]}}
	-->
	
	<!-- 数组遍历 -->
	<ul>
		<li v-for="character in characters">
			{{character}}
		</li>
	</ul>
		
	
		<template v-for="(user,index) in users">
			<h3>{{index}} . {{user.name}}</h3>
			<p>Age - {{user.age}}</p>
		</template>


		<template v-for="(user,index) in users">
			<div v-for="(val,key) in user">
			<p>{{key}} - {{val}}</p>
			</div>
		</template>
	</div>

	<script src="app.js"></script>

new Vue({

	el:"#vue-app",
	//仅限于在vue-app容器下
	data:{
		characters:["Mario","Luffy","Youshi"],
		users:[
				{name:"Henry",age:30},
