我学习了vue.js，并在HTML和CSS中创建了一个基本表单：

<!DOCTYPE HTML>
<head>
<meta charset="utf-8">
<script src="https://cdn.jsdelivr.net/npm/vue@2.5.16/dist/vue.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.10.6/moment.min.js"></script>                       
<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datetimepicker/4.17.37/js/bootstrap-datetimepicker.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.10.6/locale/pl.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jqueryui/1.12.1/jquery-ui.js"></script>
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css"/>
<link rel="stylesheet" href="https://dl.dropboxusercontent.com/s/ggg4zmxzjgz4i9b/style.css"/>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datetimepicker/4.17.37/css/bootstrap-datetimepicker.min.css" />
</head>
<body>
<div id="app">
<div class="col-xs-5" id="mail_div">
    <label for="mail">Mail:</label>
    <input v-model="mail" placeholder="E-mail adress:" type="text" class="form-control" id="mail">
</div>
<div class="col-xs-5" id="date_div">
    <label for="date">Date:</label>
    <div class='input-group date' id='datetimepicker1'>
    <input v-model="date" placeholder="Pick a date:" type='text' class="form-control" />
    <span class="input-group-addon">
        <span class="glyphicon glyphicon-calendar"></span>
    </span>
    </div>
</div>
<div class="col-xs-5" id="adress_div">
    <label for="adress">Adress:</label>
    <input v-model="adress" placeholder="Adress of the point:"type='text' class="form-control" id="adress">
</div> 
<div class="col-xs-5" id="company_div">
    <label for="company">Company:</label>
    <input v-model="company" placeholder="Company name:"type='text' class="form-control" id="company">
</div> 
<div class="col-xs-5" id="fliers_div">
    <label for="fliers">Number:</label>
    <input v-model="fliers" placeholder="Write the number:" type='number' class="form-control" id="fliers">   
</div>    
<div id="table">
<table class="table">
    <thead>
        <th scope="col">Mail</th>
        <th scope="col">Date</th>
        <th scope="col">Adress</th>
        <th scope="col">Company</th>
        <th scope="col">Number</th>
    </thead>
    <tbody>
        <tr>
          <th scope="row">{{ mail }}</th>
          <td>{{ date }}</td>
          <td>{{ adress }}</td>
          <td>{{ company }}</td>
          <td>{{ fliers }}</td>
        </tr>
    </tbody>
</table>
</div>
<div id="button">
    <div id="button_container_1">
        <button type="button" class="btn btn-primary">Add a row</button>
    </div>
    <div id="button_container_2">
        <button type="button" class="btn btn-success">Download</button>
    </div>
</div>
</div>

<script src="https://dl.dropboxusercontent.com/s/3cml0fff7nbfpot/script.js"></script>
<script type="text/javascript">

    $(function () {
        $('#datetimepicker1').datetimepicker({locale:'pl'});
    });

</script>
</body>

这是我的.js文件，到目前为止还没有做很多事情：

var app = new Vue({
 el: '#app',
 data: {
  mail:'',
  date:'',
  adress:'',
  company:'',
  fliers:''
}
})

当我提交数据时，这段代码动态更新表的行。我想达到的效果应该让我在按下蓝色按钮后输入更多行的数据。如何使用vue.js实现这一点？我已经在vue.js中找到了一些动态表的教程，但我还没有找到适合我的案例的易于掌握的解决方案。

您应进行以下更改：
1.在data属性中声明一个数组（我们称之为rowData）
1.在methods:中声明一个方法（我们称之为addItem）
1.在方法内部，从属性（mail、date、address）填充JavaScript对象
1.推送rowData数组中的对象并清除模型属性

var app = new Vue({
  el: '#app',
  data: {
    mail:'',
    date:'',
    adress:'',
    company:'',
    fliers:'',
    rowData:[] //the declared array
  },
  methods:{
    addItem(){
      var my_object = {
        mail:this.mail,
        date:this.date,
        adress:this.adress,
        company: this.company,
        fliers: this.fliers
      };
      this.rowData.push(my_object)

      this.mail = '';
      this.date = '';
      this.adress = '';
      this.company = '';
      this.fliers = '';
    }
  }
})

1.然后像这样更新你的html：

<tr v-for="item in rowData" >
  <th scope="row">{{ item.mail }}</th>
  <td>{{ item.date }}</td>
  <td>{{ item.adress }}</td>
  <td>{{ item.company }}</td>
  <td>{{ item.fliers }}</td>
</tr>

每当你将一个新对象推到rowData数组中时，VueJs会自动检测并呈现表中的一个新行。

你可能想看看这些真实的例子。他们创造了类似于你的东西。
HTML

<div id="form-message">
<button class="btn btn-default" @click="addNewMessage">New Message</button>
 <template v-for="message in messages">
 <input type="text" v-model="message.DestinationNumber" class="form-control">
 <textarea rows="3" v-model="message.TextDecoded" class="form-control"> 
</textarea>
</template>
<button class="btn btn-success" @click.prevent="submitForm">Submit</button>
<pre>{{messages | json}}</pre>

</div>

var newSingleMessage = new Vue({
 el: '#form-message',
 data: {
  messages: [
    {
        DestinationNumber: '',
        TextDecoded: ''
    }
 ],
submitted:false
},
 methods: {
addNewMessage: function(){
    this.messages.push({
        DestinationNumber: '',
        TextDecoded: ''
    });
},
submitForm: function(e) {
    console.log(this.messages);
    this.$http.post('api/outbox', {messages:this.messages})
    .then(function(response){
            //handle success
            console.log(response);
    }).error(function(response){
            //handle error
            console.log(response)
    });
    this.messages = [{ DestinationNumber: '', TextDecoded: '' }];
    this.submitted = true;
}
}
});

要使用的基本内容将是Vue对象创建中的方法部分，v-for用法和添加到按钮的@click操作。
