vue路由，vue跳转

版本信息

先安装  vue-router

npm install vue-router

 如果项目没有生成目录router相关的东西    ，就需要手动新建

 这是index.js文件内容

import { createRouter, createWebHistory } from 'vue-router'
import Login from '../components/Login.vue'

import HelloWorld from '../components/HelloWorld.vue'

const routes = [
    {path: '/login', name:'Login', component: Login},
    {path: '/:pathMatch(.*)*', name: 'NotFound', component: Login},
    {path: '/HelloWorld', name: 'HelloWorld', component: HelloWorld},
]
const router = createRouter({
    history: createWebHistory(),
    routes
})
export default router //这段后，要有回车保留一个空行否则会报错。

App.vue内容

<template>
  <div id="app">
    <router-view />//需要使用，不然不能跳转
  </div>
</template>

<script setup>

</script>

<style>
#app {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

main.js内容

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'

createApp(App).use(router).mount('#app')
