//首先，别忘了引入vue.js
<div id="user_name_01"></div>
<script src=http://www.mamicode.com/"../node_modules/vue/dist/vue.js"></script>
<script>
    var User_01 = Vue.extend({// 创建可复用的构造器
        template: ‘<p>{{firstName}} {{lastName}} age {{age}}</p>‘
    });
    var user_01 = new User_01({  // 创建一个 user 实例
        data: {
            firstName: ‘yuxie‘,
            lastName: ‘weiliang‘,
            age: 33
        }
    });
    user_01.$mount(‘#user_name_01‘)  // 挂载到元素上
</script>

// 页面结果
<div>yuxie weiliang age 33</div>

 <div id="user_name_02"></div>
  <script>
  //下面是另一种写法,模版和数据扔一块
    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>

// 页面结果
<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({// 构造器
        data: function(){
            return {
                firstName: ‘yuxie‘,
                lastName: ‘weiliang‘,
                age: 33
            }
        },
        template: ‘#children-template‘//获取HTML模版
    });
    var user_03 = new User_03();// 实例化
    user_03.$mount(‘#user_name_03‘)  // 挂载到元素上
</script>

// 页面结果
<div>yuxie weiliang age 33</div>
