<div id="vue">
<!-- v-bind:class="" 是绑定的class意思(可以写成 :class="")
v-bind:id="" 是绑定id的意思(可以写成 :id="") -->
<h1 v-bind:class="red" >VUE</h1> <!-- 这里red是变量,从下面的data里取值 -->
<h1 :class = "hd">VUE</h1>
<!-- 这里hd加上单引号后,hd就是字符串了,就是class="hd"的意思 -->
<h1 :class = "'hd'">VUE</h1>
<h1 v-bind:id="y">VUE</h1>
</div>
</body>
<script type="text/javascript">
var app=new Vue({
el:'#vue',
data:{
red:'red',
hd:'hd',
y:'y',
