Use vue to make a small example to consolidate learning.

<body>
<div id="box">
    <input type="text" v-model=&#39;command&#39; @keyup.enter=&#39;add&#39; />
    <div v-show=&#39;list.length==0&#39;>暂无留言</div>
    <ul>
        <li v-for="value in list"track-by=$index>{{value}}
            <a href="javascript:;" @click=&#39;rm($index)&#39;>删除</a>
        </li>
    </ul>
</div>
<script src="libs/vue.js"></script>
<script>
    new Vue({
        el:&#39;#box&#39;,
        data:{
            command:&#39;&#39;,
            list:[]    
        },
        methods:{
            add:function(ev){
                this.list.unshift(this.command)    
                this.command=&#39;&#39;;
            },
            rm:function(index){
                this.list.splice(index,1)    
            }
                               
        }
    })
</script>
</body>
