二级路由的配置

本例运用了二级路由，实现了一个页面中两个部分固定，中间页面可跳转的功能

1.创建项目，vue-router-template，注意项目名不能大写
2.更改config目录下index.js port:81
3.找到App.vue,修改代码

• App.vue

<template>
    <div id="app">
        <router-view />
    </div>
</template>

<script>
export default {
    name: 'App'
};
</script>

<style>
#app {
    width: 100%;
    background-color: #eee;
}
</style>

• 项目结构如图

  
  

• Index.vue

<template>
    <div>
        <div class="header">
            <div class="nav">
                <router-link to="/index" class="logo">我的班课</router-link>
                <router-link to="/task">任务中心</router-link>
                <router-link to="/lib">库管理</router-link>
                <router-link to="/ucenter">个人中心</router-link>
                <router-link to="/sign">退出</router-link>
            </div>
        </div>
        <div class="content"><router-view /></div>
    </div>
</template>

<script>
export default {
    name: 'Index',
    data() {
        return {};
    }
};
</script>

<style>
.header {
    width: 100%;
    height: 80px;
    background-color: #fff;
    display: flex;
    align-items: center;
}
.nav{
    width: 80%;
    margin: 0 auto;
}
a{
    color: darkslategrey;
    font-size: 18pt;
    text-decoration: none;
    margin-right: 50px;
}
a:hover{
    color: rgb(0, 187, 221);
}
.logo{
    margin-right: 50%;
}
.content {
    width: 80%;
    margin: 0 auto;
    margin-top: 20px;
    height: 600px;
}
</style>

• Lib.vue

    <div class="container">
        <div class="content"><router-view /></div>
        <div class="side-bar">
            <router-link to="/lib_exam">题库</router-link>
            <router-link to="/lib_resources">资源库</router-link>
            <router-link to="/lib_activity">活动库</router-link>
        </div>
    </div>
</template>

<script>
export default {
    name: 'Lib',
    data() {
        return {
            
        };
    }
};
</script>

<style scoped>
    .container{
        display: flex;
        width: 90%;
        margin: 0 auto;
    }
    .content{
        flex: 1 1 80%;
        text-align:center;
        background-color: #fff;
        padding-bottom: 20px;
    }   
    
    a{
        margin-top: 30px;
    }
    .side-bar{
        display: flex;
        flex-direction: column;
        background-color: #fff;
        margin-top: 20px;
        margin-left: 20px;
        flex: 1 1 20%;
    }
</style>
