<!--1、导入vue包-->
<script src="./js/vue.min.js"></script>
<!--2、创建vue实例（new对象）-->
<script type="text/javascript">
    var vm = new Vue({
        el: '#app',
        data: {
            id:"",
            name:"",
            list:[{
                id:1,
                name:"唐僧"
            },
             {
                id: 2,
                name: "猪八戒"
                },
             {
                id: 3,
                name: "孙悟空"
                },
             {
                id: 4,
                name: "沙悟净"
                }]
        },
        methods: {
            add(){
                // 添加数据
                this.list.unshift({
                    id:this.id,
                    name:this.name,

                })
            }
        }
    })
