}
})
</script>

</html>

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>属性绑定练习</title>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
<div id="app">
<p>姓名：{{name}}</p>
<input type="text" v-bind:value="description" />
<a v-bind:href="url">{{website}}</a>
<img :src="avatar" />
</div>
<script>
var app = new Vue({
el: '#app',
data: {
name: '尤雨溪',
description:'Vue.js创立者',
website: 'Vue.js官网',
url: 'https://cn.vuejs.org/',
avatar: 'https://gss1.bdstatic.com/9vo3dSag_xI4khGkpoWK1HF6hhy/baike/w%3D268%3Bg%3D0/sign=c08a0c60a844ad342ebf8081e8996bc9/4afbfbedab64034f29596c8ba6c379310b551da2.jpg'
}
})
</script>
</body>
</html>
语法糖：v-bind可以简写为：，如<img :src="avatar"/>
运行效果
