<html>
<head>
 <meta charset="utf-8">
 <title></title>
 //导入vue.js
 <script type="text/javascript" src="./vue.js"></script>
 //非常简单了设置了一下css样式
 <style type="text/css">
 #app{
  height: 100%;
  margin-left: 200px;
  width:50%;
  text-align: center;
  background-color: lightpink
  }
  .tab{
   width: 600px;
   margin-top: 30px;
   background-color: lightpink;
  }
  input{
   height: 25px;
   margin-top: 10px;
   border-radius:5px;
  }
 </style> 
</head>
<body>
 <p id="app">
 <p class="createForm">
  姓名:<input type="text" name="uname" v-model="userName"><br>
  年龄:<input type="text" name="uage" id="uage" v-model="userAge"><br>
  性别:<select name="gender" v-model="selected">
   <option v-for="option in options" v-bind:value="option.gender">
    {{option.gender}}
   </option>    
  </select>
  {{selected}}
  <br>
  <button type="button" v-on:click="insertInfo">创建</button>
 </p> 
 <table class="tab">
  <tr style="background-color: pink">
   <th>姓名</th>
   <th>年龄</th>
   <th>性别</th>
   <th>删除</th>
  </tr>
  <tr v-for="(person,index) in infoArr">
   <td>{{person.uname}}</td>
   <td>{{person.uage}}</td>
   <td>{{person.gender}}</td>
   <td><button v-on:click="deleteInfo(index)">删除</button></td>
  </tr>
 </table>
 </p>
</body>
</html>
<script type="text/javascript">
 new Vue({
  el:"#app",
  data:{
   msg:"hello",
   selected:'女',
   userName:'',
   userAge:'',
   options:[
   {gender:"男"},
   {gender:"女"}
   ],
   infoArr:[]
  },
  methods:{
  //添加数据的方法
   insertInfo(){
    var obj={};
    obj.uname=this.userName;
    obj.uage=this.userAge;
    obj.gender=this.selected;
    this.infoArr.push(obj);
    console.log(obj);
   },
   //删除的方法
   deleteInfo(index){
    this.infoArr.splice(index,1);
   }
  }  
 })
</script>
