vue3.0之Router的使用

先创建一个 vue项目

在这里插入图片描述

 命名式 路由

命名式 路由

- 就是给路由添加 name属性
import { createRouter, createWebHistory } from 'vue-router'
import Home from '../views/home/Home.vue'
const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: [
    {
      path: '/',
      name: 'Login',
      component: () => import('../views/login/Login.vue'),
    },
    {
      path: '/reg',
      name: 'Reg',
      component: () => import('../views/reg/Reg.vue'),
    },
  ],
})
export default router

使用 RouterLink

<script setup lang="ts">
import { RouterLink, RouterView } from 'vue-router'
</script>
<template>
  <div>
    <RouterView />
    <RouterLink :to="{ name: 'Login' }">login</RouterLink>
    <RouterLink style="margin-left: 10px" :to="{ name: 'Reg' }">reg</RouterLink>
  </div>
</template>
<style>
@import '@/assets/base.css';
#app {
  max-width: 1280px;
  margin: 0 auto;
  padding: 2rem;
  font-weight: normal;
}
</style>

 编程式导航

router / index.ts

import { createRouter, createWebHistory } from 'vue-router'
import Home from '../views/home/Home.vue'
const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: [
    {
      path: '/',
      name: 'Login',
      component: () => import('../views/login/Login.vue'),
    },
    {
      path: '/login',
      name: 'Login',
      component: () => import('../views/login/Login.vue'),
    },
    {
      path: '/reg',
      name: 'Reg',
      component: () => import('../views/reg/Reg.vue'),
    },
  ],
})
export default router

App.vue 跳转到路由

router.push(’/login’) 跳转字符串

<template>
  <div>
    <button @click="loginClick">登录</button>
    <button @click="regClick">注册</button>
    <RouterView />
  </div>
</template>
<script setup lang="ts">
import { RouterLink, RouterView, useRouter } from 'vue-router'
const router = useRouter()
const loginClick = () => {
  router.push('/login')
}
const regClick = () => {
  router.push('/reg')
}
</script>
<style>
@import '@/assets/base.css';
#app {
  max-width: 1280px;
  margin: 0 auto;
  padding: 2rem;
  font-weight: normal;
}
</style>

 router.push({ path: url }) 对象的形式

<template>
  <div>
    <button @click="toPage('/login', 'Login')">登录</button>
    <button @click="toPage('/reg', 'Reg')">注册</button>
    <RouterView />
  </div>
</template>
<script setup lang="ts">
import { RouterLink, RouterView, useRouter } from 'vue-router'
const router = useRouter()
const toPage = (url: string, name: string) => {
  // 对象的形式
  router.push({
     path: url,
  })
}
</script>

命名式路由模式 router.push({ name: name })

<template>
  <div>
    <button @click="toPage('/login', 'Login')">登录</button>
    <button @click="toPage('/reg', 'Reg')">注册</button>
    <RouterView />
  </div>
</template>
<script setup lang="ts">
import { RouterLink, RouterView, useRouter } from 'vue-router'
const router = useRouter()
const toPage = (url: string, name: string) => {
  // 命名式路由模式
  router.push({
    name: name,
  })
}
</script>

历史记录

RouterLink 跳转路由

<template>
  <div>
    <RouterLink replace :to="{ name: 'Login' }">login</RouterLink>
    <RouterLink replace style="margin-left: 10px" :to="{ name: 'Reg' }">reg</RouterLink>
    <RouterView />
  </div>
</template>
<script setup lang="ts">
import { RouterLink, RouterView, useRouter } from 'vue-router'
const router = useRouter()
</script>

效果

编程式导航

<template>
  <div>
    <button @click="toPage('/login', 'Login')">登录</button>
    <button @click="toPage('/reg', 'Reg')">注册</button>
    <RouterView />
  </div>
</template>
<script setup lang="ts">
import { RouterLink, RouterView, useRouter } from 'vue-router'
const router = useRouter()
const toPage = (url: string, name: string) => {
  // 字符串的形式
  router.replace(url)
  // 对象的形式
  // router.push({
  //   path: url,
  // })
  // 命名式路由模式
  // router.push({
  //   name: name,
  // })
}
</script>

非历史 记录的导航 还可以使用 方法

<template>
  <div>
    <button @click="toPage('/login', 'Login')">登录</button>
    <button @click="toPage('/reg', 'Reg')">注册</button>
    <button @click="nextClick">next</button>
    <button @click="prerClick">prer</button>
    <RouterView />
  </div>
</template>
<script setup lang="ts">
import { RouterLink, RouterView, useRouter } from 'vue-router'
const router = useRouter()
const toPage = (url: string, name: string) => {
  // 字符串的形式
  router.push(url)
}
const prerClick = () => {
  router.go(-1)
}
const nextClick = () => {
  router.go(1)
}
</script>

路由传参

query 方式传参(拼接在url上)

商品页

<template>
  <div class="login">
    <div>Login</div>
    <div v-for="item in data" :key="item.id">{{ item.name }} -- {{ item.price }} <button @click="view(item)">详情</button></div>
  </div>
</template>
<script setup lang="ts">
import { reactive } from 'vue'
import { useRouter } from 'vue-router'
import { data } from './List.json'
const router = useRouter()
type List = {
  name: string
  price: number
  id: number
}
const view = (List: List) => {
  router.push({
    name: 'Reg',
    query: List,
  })
}
</script>
<script lang="ts">
export default {
  name: 'Login',
}
</script>
<style lang="scss" scoped>
.login {
  width: 400px;
  height: 400px;
  background: pink;
}
</style>

List.json

{
  "data": [{
    "name": "菜鸡",
    "price": 111,
    "id": 1
  }, {
    "name": "菜狗",
    "price": 222,
    "id": 2
  }, {
    "name": "菜鸟",
    "price": 333,
    "id": 3
  }]
}

动态路由的 传参(需要在路由的path添加一个动态参数,浏览器刷新后,数据不会丢失)

路由

import { createRouter, createWebHistory } from 'vue-router'
import Home from '../views/home/Home.vue'
const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  routes: [
    {
      path: '/',
      name: 'Login',
      component: () => import('../views/login/Login.vue'),
    },
    {
      path: '/login',
      name: 'Login',   component: () => import('../views/login/Login.vue'),
    },
    {
      path: '/reg/:id',
      name: 'Reg',
      component: () => import('../views/reg/Reg.vue'),
    },
  ],
})
export default router

商品页

<template>
  <div class="login">
    <div>Login</div>
    <div v-for="item in data" :key="item.id">{{ item.name }} -- {{ item.price }} <button @click="view(item)">详情</button></div>
  </div>
</template>
<script setup lang="ts">
import { reactive } from 'vue'
import { useRouter } from 'vue-router'
import { data } from './List.json'
const router = useRouter()
type List = {
  name: string
  price: number
  id: number
}
const view = (List: List) => {
  router.push({
    name: 'Reg',
    params: {
      id: List.id,
    },
  })
}
</script>
<script lang="ts">
export default {
  name: 'Login',
}
</script>
<style lang="scss" scoped>
.login {
  width: 400px;
  height: 400px;
  background: pink;
}
</style>

<template>
  <div class="reg">
    <div>我是详情页面 -- <button @click="router.back()">返回</button></div>
    <div>
      <div>唯一值:{{ item.id }}</div>
      <div>名称:{{ item.name }}</div>

<style lang="scss" scoped>
.reg {
