[Vue3：Vite构建项目]：安装router实现登录页面路由跳转

一：前置依赖

查看依赖

根目录下 package.json 文件

 "dependencies": {"vue": "^3.4.21","vue-router": "^4.3.2"},

安装vite npm create vite@latest sys-instruction-0607 --template vue-ts

安装路由：npm install vue-router@4

安装elementUI：npm install element-plus --save

二：配置文件：views（登录和列表页面），router（views页面路由）

App.vue 顶层路由页面调整：

<script setup>
</script>
<template><div><router-view key = "$route.fullPath"></router-view></div>
</template>
<style scoped>
</style>
<script>export default {}
</script>

创建views目录添加文件Login和Page vue：

<template> <div class="login-container"><h1>教师管理系统</h1><input type="text" placeholder="用户名" v-model="username" /><input type="password" placeholder="密码" v-model="password" /><button @click="login">登录</button></div>
</template>
<script>export default {data() {return {username: '',password: ''};},computed: {key() {return this.$route.path + Math.random()}},methods: {login() {// 这里应该是登录验证逻辑，例如向服务器发送请求// 验证成功后，可以跳转到主页或其他页面this.$router.push('/page');}}}
</script>

<template> <div class="login-container"><h1>Page 分页页面t</h1><button @click="handle">Login</button></div>
</template>
<script>import { useRouter } from 'vue-router'export default {methods: {handle () {this.$router.push("pagec")}}}
</script>

创建router目录添加index路由配置

import type { App } from 'vue'
import type { RouteRecordRaw } from 'vue-router'
import { createRouter, createWebHistory } from 'vue-router'
// import moduleroutes from './module/router'const moduleroutes = [{path: '/:pathMatch(.*)*',component: () => import('../views/Login.vue'),// redirect: '/Login',name: 'Login',meta: {}},{path: '/page',component: () => import('../views/Page.vue'),// redirect: '/page',name: 'Page',meta: {}}
]// 创建路由实例
const router = createRouter({history: createWebHistory(), // createWebHashHistory URL带#，createWebHistory URL不带#strict: true,routes: moduleroutes as RouteRecordRaw[],scrollBehavior: () => ({ left: 0, top: 0 })
})export const resetRouter = (): void => {const resetWhiteNameList = ['Redirect', 'Login', 'NoFind', 'Root']router.getRoutes().forEach((route) => {const { name } = routeif (name && !resetWhiteNameList.includes(name as string)) {router.hasRoute(name) && router.removeRoute(name)}})
}export const setupRouter = (app: App<Element>) => {app.use(router)
}export default router

根目录mainjs文件引入index路由,elementUI配置

import { createApp } from 'vue'
import './style.css'
import App from './App.vue' 
import router from './router' //引入router
import ElementPlus from 'element-plus' //引入ElementPlusconst app=createApp(App)app.use(router) //使用router
app.use(ElementPlus) //使用ElementPlusapp.mount('#app')

三：效果

访问 http://localhost:5173/ 根据路由默认路由到Loginvue页面
登录跳转路由到Page页面
