登录页

<template>
  <div>
    <div class="login">
      <h3>图书管理系统</h3>
      <div class="user">
        <span>账号：</span><input type="text" v-model="user" />
      </div>
      <div class="pwd">
        <span>密码：</span><input type="text" v-model="pwd" />
      </div>
      <div class="btn">
        <button @click="login">登录</button>
      </div>
    </div>
  </div>
</template>

这是一个简单的登录页的布局（css参考完整代码）

我们现在要实现输入账号和密码就能够跳转到home页怎么实现?

很简单

创建home页
配置路由
在登录点击事件里实现路由跳转

创建home页

配置路由

{
      path: "/home",
      component: Home,
      name: "home",
    },

在登录点击事件里实现路由跳转

import { useRouter } from "vue-router";
import { ref } from "vue";

const user = ref("");
const pwd = ref("");
const router = useRouter();

const login = () => {
  if (user.value !== "" && pwd.value !== "") {
    localStorage.setItem("user", user.value);
    router.push("/home");
  }
};

通过 ref 创建了两个响应式变量 user 和 pwd 来存储用户名和密码

然后，使用 useRouter 获取了路由实例 router

定义的 login 函数用于处理登录逻辑。当用户名和密码都不为空时，将用户名存储到本地存储 localStorage 中，并通过 router.push('/home') 跳转到 /home 路由对应的页面

接下来你就能实现下面的效果了

这里我们就了解了一级路由了

home页面

我们通过home页面来讲解二级路由

首先我们创建基础页面

<div class="home">
      <header class="header">
        <div class="name">图书管理系统</div>
        <div class="userInfo">
          <span>欢迎 {{ user }}</span>
        </div>
      </header>
      <section class="main">
        <div class="menu">
          <ul class="menu-list">
            <li class="list-item" v-for="item in menu" :key="item.title">
              <router-link :to="`/home${item.path}`">{{
                item.title
              }}</router-link>
            </li>
          </ul>
        </div>

        <div class="content">
          <RouterView></RouterView>
        </div>
      </section>
    </div>

同样是三步走

创建页面
配置路由
添加router-link触发

创建页面

创建好对应的页面

配置路由

{
      path: "/home",
      component: Home,
      name: "home",
      children: [
        {
          path: "/home/add-book",
          component: AddBook,
          name: "addbook",
        },
        {
          path: "/home/borrow",
          component: Borrow,
          name: "borrow",
        },
        {
          path: "/home/category",
          component: Category,
          name: "category",
        },
        {
          path: "/home/search",
          component: Search,
          name: "search",
        },
      ],
    },

添加router-link触发

我们首先创建一个用来存储菜单数据

export const menu = [
    {id: 1, title: '图书分类', path: '/category'},
    {id: 2, title: '查询图书', path: '/search'},
    {id: 3, title: '添加图书', path: '/add-book'},
    {id: 4, title: '借阅管理', path: '/borrow'}
  ]

通过import { menu } from "../menuData";可以导入数据

使用v-for渲染数据

<li class="list-item" v-for="item in menu" :key="item.title">
              <router-link :to="`/home${item.path}`">{{
                item.title
              }}</router-link>
</li>

现在我们就能实现二级路由的效果了

一级路由和二级路由的区别主要在于路由的配置是不同的

总结

本文通过一个小demo，讲解了路由的使用，路由的使用主要就是在于路由的配置，相信看到这里的你一定会有收获的
