//首先，別忘了引入vue.js
<div id="user_name_01"></div>
<script src="../node_modules/vue/dist/vue.js"></script>
<script>
  var User_01 = Vue.extend({// 創(chuàng)建可復(fù)用的構(gòu)造器
    template: '<p>{{firstName}} {{lastName}} age {{age}}</p>'
  });
  var user_01 = new User_01({ // 創(chuàng)建一個 user 實例
    data: {
      firstName: 'yuxie',
      lastName: 'weiliang',
      age: 33
    }
  });
  user_01.$mount('#user_name_01') // 掛載到元素上
</script>

// 頁面結(jié)果
<div>yuxie weiliang age 33</div>

 <div id="user_name_02"></div>
 <script>
 //下面是另一種寫法,模版和數(shù)據(jù)扔一塊
  var User_02 = Vue.extend({
   template: '<p>{{firstName}} {{lastName}} age {{age}}</p>',  
  data: function(){
      return {
        firstName: 'yuxie',
        lastName: 'weiliang',
        age: 33
      }
    }
  });
  var user_02 = new User_02({data:{ age: 888888 }});//修改了age
  user_02.$mount('#user_name_02')
</script>

// 頁面結(jié)果
<div>yuxie weiliang age 888888</div>

//容器
<div id="user_name_03"></div>
//模版
<template id="children-template">
  <p>{{firstName}} {{lastName}} age {{age}}</p>
</template>
//js
<script>
  var User_03 = Vue.extend({// 構(gòu)造器
    data: function(){
      return {
        firstName: 'yuxie',
        lastName: 'weiliang',
        age: 33
      }
    },
    template: '#children-template'//獲取HTML模版
  });
  var user_03 = new User_03();// 實例化
  user_03.$mount('#user_name_03') // 掛載到元素上
</script>

// 頁面結(jié)果
<div>yuxie weiliang age 33</div>
