一、 通过<script>直接引入开发版本的Vue
二、hello world 代码示例
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Hello World</title>
<script src="./vue.js"></script>
</head>
<body>
<!-- <div id="app"></div> -->
<!-- 插值表达式 -->
<div id="app">{{ content }}</div>
<script>
/*let dom = document.getElementById('app')
dom.innerHTML = 'hello world'
setTimeout(function(){
dom.innerHTML = 'bye world'
}, 2000)*/
let vm = new Vue({ //创建 Vue 实例
el: '#app', //接管区域
data: { //数据
content: 'hello world'
}
})
setTimeout(function(){
vm.$data.content = 'bye world'
}, 2000)
</script>
</body>
</html>
