//在使用vue之前必须实例化vue对象
new Vue({

},
methods: {
greet:function(name){
return 'Hello Word' + name + " " + this.name;
},
}
})
2.在html中编写的内容：
<!DOCTYPE html>
<html >
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>index.html</title>
<!-- 用于在线引用vue.js -->
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<!-- 引用css文件 -->
<link rel="stylesheet" href="../css/style.css" target="_blank" rel="external nofollow" >

<div id="vue-app">

<h1>{{ name }}</h1>
<p>{{greet('朱旭')}}</p>
</div>
<script src="../js/app.js"></script>
</body>
