一 概念
```html
<div id='app'>
<p v-on:click='func'>{{ msg }}</p>
</div>
<script>
new Vue({
el: '#app',
data: {
msg: '段落'
},
methods: {
func: function() {
alert(this.msg)
}
}
})
</script>
```二 代码示范
<!DOCTYPE html>
<html lang="zh">
<head>
<meta charset="UTF-8">
<title>methods</title>
<style type="text/css">
.box {
background-color: orange
}
</style>
</head>
<body>
<div );
}
}
})
</script>
</html>
