Vue组件 - 单文件组件

内容

  1. xxx.vue文件 => 内部书写组件

    1. template => 组件的结构
    2. script => 组件相关交互的代码
    3. style => 组件的样式
  2. 代码示例

需要通过脚手架才能将下述文件成功运行起来,其中main.js是入口。

School.vue

<template>
	<div class="demo">
		<h2>学校名称:{{name}}</h2>
		<h2>学校地址:{{address}}</h2>
		<button @click="showName">点我提示学校名</button>	
	</div>
</template>

<script>
	 export default {
		name:'School',
		data(){
			return {
				name:'Vue知识',
				address:'北京昌平'
			}
		},
		methods: {
			showName(){
				alert(this.name)
			}
		},
	}
</script>

<style>
	.demo{
		background-color: orange;
	}
</style>
