<!doctype html>
<html>
 <head>
 <meta charset="UTF-8">
 <title>{{}}的使用</title>
 <script src="js/vue.js"></script>
 </head>
 <body>
 <p id="container">
  <h1>{{msg}}</h1>
  <h4>{{cart.brand}}</h4>
 <!--在双花括号中 执行运算表达式 -->
 <p> 3 + 5 = {{ 3 + 5 }}</p>
 </p>
 <script>
  new Vue({
   el:"#container",
   data:{
    msg:"Hello VueJs",
    cart:{
     brand:"Volvo",price:30
    }
   }
  })

 <meta charset="UTF-8">
 <title>双花括号的练习</title>
 <script src="js/vue.js"></script>
 </head>

  <h4>逻辑运算3>5 && 2>1:{{3>5 && 2>1}}</h4>
  <h4>{{!hasMore}}</h4>
  <h4>{{totalNum>count?"大于":"小于"}}</h4>
 </p>
 <script>
  new Vue({
   el:"#container",
   data:{
    msg:"Hello VueJs",
