下列為實現程式碼

css:

*{
            margin: 0;
            padding: 0;
        }
        #app ul{
            width: 300px;
            height: 30px;
            list-style: none;
        }
        #app>ul>li{
            width: 100px;
            height: 30px;
            float: left;
        }

        </li>
        <li>
            <router-link to="/dey">第二頁</router-link>

        <li>
            <router-link to="/dsy">第三頁</router-link>
        </li>
    </ul>
    <router-view></router-view>
</div>

<template id="DyyDay">
    <div>

    </div>
</template>

<template id="DsyDay">
    <div>
        <h1>Home</h1>
        <router-link to="/dsy/home1">home1</router-link>
        <router-link to="/dsy/home2">home2</router-link>

    </div>
</template>

<template id="home1">
    <h1>我是home1</h1>
</template>

<template id="home2">
    <h1>我是home2</h1>

js.

let Dyy={template:`#DyyDay`};
    let Dey={template:`#DeyDay`};
    let Dsy={template:`#DsyDay`};
    let home1={template:`#home1`};
    let home2={template:`#home2`};
    let router=new VueRouter({
        routes:[
            { path:'/',redirect:"dyy" },
            { path:'/dyy',component:Dyy },
            { path:'/dey',component:Dey },
            { path:'/dsy',component:Dsy ,
                children:[

                ]
            }]
    });
    let app=new Vue({
