1，v-html： 操作元素中的HTML标签
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div id='app'>
<input type="text" v-model='msg'>
<p v-html='msg'>{{msg}}</p>
</div>
<script src="../js/vue.js"></script>
<script>
new Vue({
el:'#app',
data:{
msg:'hello'
}
})
</script>
</body>
</html>
2，v-text： 操作元素中的纯文本
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div id='app'>
<input type="text" v-model='msg'>
<h3 v-text='msg'>{{msg}}</h3>
</div>
<script src="../js/vue.js"></script>
<script>
new Vue({
el:'#app',
data:{
msg:'hello'
}
})
</script>
</body>
</html>
3，v-once：只绑定一次
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div id='app'>
<input type="text" v-model='msg'>
<a href="" v-once>{{msg}}</a>
</div>
<script src="../js/vue.js"></script>
<script>
new Vue({
el:'#app',
data:{
msg:'hello'
}
})
</script>
</body>
</html>
4，v-pre：原样输出
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<div id='app'>
<input type="text" v-model='msg'>
<h1 v-pre>{{msg}}</h1>
</div>
<script src="../js/vue.js"></script>
<script>
new Vue({
el:'#app',
data:{
msg:'hello'
}
})
</script>
</body>
</html>
