注：v-bind指令可以缩写为:冒号。如：:class=”expression”。
例子：
在本例子中，当鼠标悬停在span标签的文字上时，会显示加载网页的时间。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<script src="https://unpkg.com/vue/dist/vue.js"></script>
</head>
<body>
<div id="app">
<span v-bind:title="message">Hover your mouse over me</span>
</div>
<script>
var app = new Vue({
el: '#app',
data: {
message: 'you loaded this page on ' + new Date()
}
})
</script>
</body>
</html>v-on指令
用于监听DOM事件，语法与v-bind类似，如监听点击事件v-on:click=”doSth”。
注：v-on指令可以缩写为@符号。如：@click=”doSth”。
例子：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<script src="https://unpkg.com/vue/dist/vue.js"></script>
</head>
<body>
<div id="app">
<p><input type="text" v-model="message"></p>
<p>
<button v-on:click="greet">Greet</button>
</p>
<p>
<button v-on:click="say('hello vue')">Hello</button>
</p>
</div>
<script>
var app = new Vue({
el: '#app',
data: {
message: 'Greet to Vue'
},
methods: {
greet: function(){
alert(this.message);
},
say: function(msg){
alert(msg);
}
}
})
</script>
</body>
</html>运行结果：
