案例代码：

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8" />
        <meta http-equiv="X-UA-Compatible" content="IE=edge" />
        <meta name="viewport" content="width=device-width, initial-scale=1.0" />
        <title>Document</title>
    </head>
    <style>
        * {
            margin: 0;
            padding: 0;
        }
        ul {
            width: 400px;
            margin-left: 50px;
        }
        li {
            list-style: none;
            line-height: 30px;
            border-bottom: 1px solid #bdbdbd;
        }
    </style>
    <body>
        <div id="app">
            <input type="text" v-model="keyword" />
            <ul>
                <li v-for="(item,index) in list" :key="index">{{ item.name}}</li>
            </ul>
        </div>
    </body>
    <script src="https://cdn.bootcdn.net/ajax/libs/vue/2.6.12/vue.js"></script>
    <script>
        new Vue({
            data() {
                return {
                    keyword: '',
                    list1: [
                        { name: 'test1', area: 'aa' },
                        { name: 'test2', area: 'bb' },
                        { name: 'test3', area: 'cc' },
                        { name: 'test4', area: 'dd' },
                        { name: 'test5', area: 'ee' },
                        { name: 'test6', area: 'ff' },
                        { name: 'test7', area: 'gg' },
                        { name: 'test8', area: 'hh' }
                    ]
                };
            },
            computed: {
                list() {
                    return this.list1.filter(item => item.name.includes(this.keyword));
                }
            }
        }).$mount('#app');
    </script>
