<script src="./vue.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div id="app">
{{ message }} {{name}}
</div>
<script type="text/javascript">
var app = new Vue({
el: '#app',
data: {
message: 'Hello Vue!',

}
});
</script>
</body>
</html>

```
<div id="vue_det">
<h1>site : {{site}}</h1>
<h1>url : {{url}}</h1>
<h1>{{details()}}</h1>
</div>
<script type="text/javascript">
var vm = new Vue({
