本文主要对Vue的路由简单功能使用进行简单的使用总结
提示:以下是本篇文章正文内容
一、相关理解
1.1 vue-router的理解
- vue 的一个插件库,专门用来实现
SPA 应用
1.2 对SPA应用的理解
1、单页 Web 应用(single page web application,SPA)
2、整个应用只有一个完整的页面
3、点击页面中的导航链接不会刷新页面,只会做页面的局部更新
4、数据需要通过ajax请求获取
1.3 对路由的理解
1、什么是路由?
(1)、一个路由就是一组映射关系(key - value)
(2)、key 为路径,value 可能是 function 或 componen
2、路由分类
后端路由:
理解:value 是 function,用于处理客户端提交的请求
工作过程:服务器接收到一个请求时,根据请求路径找到匹配的函数来处理请求,返回响应数据
前端路由:
理解:value 是 component,用于展示页面内容
工作过程:当浏览器的路径改变时,对应的组件就会显示
二、基本路由
2.1 基本使用
下载
vue-router:npm i vue-router
src/router/index.js:
//该文件专门用于创建整个应用的路由器
import VueRouter from "vue-router";
//引入组件
import Home from '../components/Home'
import About from '../components/About'
//创建并暴露一个路由器
export default new VueRouter({
routes:[
{
path:'/about',
component:About
},
{
path:'/home',
component:Home
}
]
})
src/main.js:
import Vue from 'vue'
import App from './App.vue'
import VueRouter from 'vue-router'
import router from './router'
Vue.config.productionTip = false
Vue.use(VueRouter)
new Vue({
el:"#app",
render: h => h(App),
router
})
src/App.vue:
<template>
<div>
<div class="row">
<div class="col-xs-offset-2 col-xs-8">
<div class="page-header"><h2>Vue Router Demo</h2></div>
</div>
</div>
<div class="row">
<div class="col-xs-2 col-xs-offset-2">
<div class="list-group">
<!-- 原始html中我们使用a标签实现页面跳转 -->
<!-- <a class="list-group-item active" href="./about.html">About</a>
<a class="list-group-item" href="./home.html">Home</a> -->
<!-- Vue中借助router-link标签实现路由的切换 -->
<router-link class="list-group-item" active-class="active" to="/about"> About
</router-link>
<router-link class="list-group-item" active-class="active" to="/home">
Home
</router-link>
</div>
</div>
<div class="col-xs-6">
<div class="panel">
<div class="panel-body">
<!-- 指定组件的呈现位置 -->
<router-view></router-view>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
name:'App',
}
</script>
src/components/Home.vue:
<template>
<h2>我是Home组件的内容</h2>
</template>
<script>
export default {
name:'Home'
}
</script>
src/components/About.vue:
<template>
<h2>我是About组件的内容</h2>
</template>
<script>
export default {
name:'About'
}
</script>
2.2 总结
使用步骤:
1、安装vue-router
,命令:npm i vue-router
2、应用插件:Vue.use(VueRouter)
3、编写router
配置项:
//引入VueRouter
import VueRouter from 'vue-router'
//引入Luyou 组件
import About from '../components/About'
import Home from '../components/Home'
//创建router实例对象,去管理一组一组的路由规则
const router = new VueRouter({
routes:[
{
path:'/about',
component:About
},
{
path:'/home',
component:Home
}
]
})
//暴露router
export default router
4、实现切换( active-class
可配置高亮样式):
<router-link active-class="active" to="/about">About</router-link>
5、指定展示位:<router-view></router-view>
三、几个注意事项
1、路由组件通常存放在pages
文件夹,一般组件通常存放在components
文件夹
比如上一节的案例就可以修改为:
src/pages/Home.vue:
<template>
<h2>我是Home组件的内容</h2>
</template>
<script>
export default {
name:'Home'
}
</script>
src/pages/About.vue:
<template>
<h2>我是About组件的内容</h2>
</template>
<script>
export default {
name:'About'
}
</script>
src/router/index.js:
//该文件专门用于创建整个应用的路由器
import VueRouter from "vue-router";
//引入组件
import Home from '../pages/Home'
import About from '../pages/About'
//创建并暴露一个路由器
export default new VueRouter({
routes:[
{
path:'/about',
component:About
},
{
path:'/home',
component:Home
}
]
})
src/components/Banner.vue:
<template>
<div class="col-xs-offset-2 col-xs-8">
<div class="page-header"><h2>Vue Router Demo</h2></div>
</div>
</template>
<script>
export default {
name:'Banner'
}
</script>
src/App.vue:
<template>
<div>
<div class="row">
<Banner/>
</div>
<div class="row">
<div class="col-xs-2 col-xs-offset-2">
<div class="list-group">
<!-- 原始html中我们使用a标签实现页面跳转 -->
<!-- <a class="list-group-item active" href="./about.html">About</a>
<a class="list-group-item" href="./home.html">Home</a> -->
<!-- Vue中借助router-link标签实现路由的切换 -->
<router-link class="list-group-item" active-class="active" to="/about">
About
</router-link>
<router-link class="list-group-item" active-class="active" to="/home">
Home
</router-link>
</div>
</div>
<div class="col-xs-6">
<div class="panel">
<div class="panel-body">
<!-- 指定组件的呈现位置 -->
<router-view></router-view>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
import Banner from './components/Banner.vue'
export default {
name:'App',
components:{
Banner}
}
</script>
2、通过切换,“隐藏”了的路由组件,默认是被销毁掉的,需要的时候再去挂载
3、每个组件都有自己的$route属性,里面存储着自己的路由信息
4、整个应用只有一个router,可以通过组件的$router属性获取到
四、多级路由
4.1 基本实现
src/pages/Home.vue:
<template>
<div>
<h2>Home组件内容</h2>
<div>
<ul class="nav nav-tabs">
<li>
<router-link class="list-group-item" active-class="active" to="/home/news">
News
</router-link>
</li>
<li>
<router-link class="list-group-item" active-class="active" to="/home/message">
Message
</router-link>
</li>
</ul>
<router-view></router-view>
</div>
</div>
</template>
<script>
export default {
name:'Home'
}
</script>
src/pages/News.vue:
<template>
<ul>
<li>news001</li>
<li>news002</li>
<li>news003</li>
</ul>
</template>
<script>
export default {
name:'News'
}
</script>
src/pages/Message.vue:
<template>
<ul>
<li>
<a href="/message1">message001</a>
</li>
<li>
<a href="/message2">message002</a>
</li>
<li>
<a href="/message/3">message003</a>
</li>
</ul>
</template>
<script>
export default {
name:'News'
}
</script>
src/router/index.js:
//该文件专门用于创建整个应用的路由器
import VueRouter from "vue-router";
//引入组件
import Home from '../pages/Home'
import About from '../pages/About'
import News from '../pages/News'
import Message from '../pages/Message'
//创建并暴露一个路由器
export default new VueRouter({
routes:[
{
path:'/about',
component:About
},
{
path:'/home',
component:Home,
children:[
{
path:'news',
component:News
},
{
path:'message',
component:Message
}
]
}
]
})
效果:
4.2 总结
1、配置路由规则,使用children配置项:
routes:[
{
path:'/about',
component:About,
},
{
path:'/home',
component:Home,
children:[ //通过children配置子级路由
{
path:'news', //此处一定不要写:/news
component:News
},
{
path:'message', //此处一定不要写:/message
component:Message
}
]
}
]
2、跳转(要写完整路径):<router-link to="/home/news">News</router-link>
五、 路由的query参数
src/router.index.js:
//该文件专门用于创建整个应用的路由器
import VueRouter from "vue-router";
//引入组件
import Home from '../pages/Home'
import About from '../pages/About'
import News from '../pages/News'
import Message from '../pages/Message'
import Detail from '../pages/Detail'
//创建并暴露一个路由器
export default new VueRouter({
routes:[
{
path:'/about',
component:About
},
{
path:'/home',
component:Home,
children:[
{
path:'news',
component:News
},
{
path:'message',
component:Message,
children:[
{
path:'detail',
component:Detail
}
]
}
]
}
]
})
src/pages/Detail.vue:
<template>
<ul>
<li>消息编号:{
{
$route.query.id}}</li>
<li>消息标题:{
{
$route.query.title}}</li>
</ul>
</template>
<script>
export default {
name:'Detail'
}
</script>
src/pages/Message.vue:
<template>
<div>
<ul>
<li v-for="m in messageList" :key="m.id">
<!-- 跳转路由并携带query参数,to的字符串写法 -->
<!-- <router-link :to="`/home/message/detail?id=${m.id}&title=${m.title}`">
{
{
m.title}}
</router-link> -->
<!-- 跳转路由并携带query参数,to的对象写法 -->
<router-link :to="{
path:'/home/message/detail',
query:{
id:m.id,
title:m.title
}
}">
{
{
m.title}}
</router-link>
</li>
</ul>
<hr/>
<router-view></router-view>
</div>
</template>
<script>
export default {
name:'News',
data(){
return{
messageList:[
{
id:'001',title:'消息001'},
{
id:'002',title:'消息002'},
{
id:'003',title:'消息003'}
]
}
}
}
</script>
效果:
总结:
1、传递参数:
<!-- 跳转并携带query参数,to的字符串写法 -->
<router-link :to="/home/message/detail?id=666&title=你好">跳转</router-link>
<!-- 跳转并携带query参数,to的对象写法 -->
<router-link :to="{
path:'/home/message/detail',
query:{
id:666,
title:'你好'
}
}">跳转</router-link>
2、接收参数:
$route.query.id
$route.query.title
六、 命名路由
src/router/index.js:
//该文件专门用于创建整个应用的路由器
import VueRouter from "vue-router";
//引入组件
import Home from '../pages/Home'
import About from '../pages/About'
import News from '../pages/News'
import Message from '../pages/Message'
import Detail from '../pages/Detail'
//创建并暴露一个路由器
export default new VueRouter({
routes:[
{
path:'/about',
component:About
},
{
path:'/home',
component:Home,
children:[
{
path:'news',
component:News
},
{
path:'message',
component:Message,
children:[
{
//name配置项为路由命名
name:'xiangqing',
path:'detail',
component:Detail
}
]
}
]
}
]
})
src/pages/Message.vue:
<template>
<div>
<ul>
<li v-for="m in messageList" :key="m.id">
<!-- 跳转路由并携带query参数,to的字符串写法 -->
<!-- <router-link :to="`/home/message/detail?id=${m.id}&title=${m.title}`">
{
{
m.title}}
</router-link> -->
<!-- 跳转路由并携带query参数,to的对象写法 -->
<router-link :to="{
//使用name进行跳转
name:'xiangqing',
query:{
id:m.id,
title:m.title
}
}">
{
{
m.title}}
</router-link>
</li>
</ul>
<hr/>
<router-view></router-view>
</div>
</template>
<script>
export default {
name:'News',
data(){
return{
messageList:[
{
id:'001',title:'消息001'},
{
id:'002',title:'消息002'},
{
id:'003',title:'消息003'}
]
}
}
}
</script>
总结:
命名路由:
1、作用:可以简化路由的跳转
2、如何使用:
(1)给路由命名:
(2)简化跳转:
(1)给路由命名:
{
path:'/demo',
component:Demo,
children:[
{
path:'test',
component:Test,
children:[
{
name:'hello' //给路由命名
path:'welcome',
component:Hello,
}
]
}
]
}
(2)简化跳转:
<!--简化前,需要写完整的路径 -->
<router-link to="/demo/test/welcome">跳转</router-link>
<!--简化后,直接通过名字跳转 -->
<router-link :to="{name:'hello'}">跳转</router-link>
<!--简化写法配合传递参数 -->
<router-link
:to="{
name:'hello',
query:{
id:666,
title:'你好'
}
}"
>跳转</router-link>
七、 路由的params参数
src/router/index.js:
//该文件专门用于创建整个应用的路由器
import VueRouter from "vue-router";
//引入组件
import Home from '../pages/Home'
import About from '../pages/About'
import News from '../pages/News'
import Message from '../pages/Message'
import Detail from '../pages/Detail'
//创建并暴露一个路由器
export default new VueRouter({
routes:[
{
path:'/about',
component:About
},
{
path:'/home',
component:Home,
children:[
{
path:'news',
component:News
},
{
path:'message',
component:Message,
children:[
{
name:'xiangqing',
path:'detail/:id/:title',//使用占位符声明接收params参数
component:Detail
}
]
}
]
}
]
})
src/pages/Message.vue:
<template>
<div>
<ul>
<li v-for="m in messageList" :key="m.id">
<!-- 跳转路由并携带params参数,to的字符串写法 -->
<!-- <router-link :to="`/home/message/detail/${m.id}/${m.title}`">
{
{
m.title}}
</router-link> -->
<!-- 跳转路由并携带params参数,to的对象写法 -->
<router-link :to="{
name:'xiangqing',
params:{
id:m.id,
title:m.title
}
}">
{
{
m.title}}
</router-link>
</li>
</ul>
<hr/>
<router-view></router-view>
</div>
</template>
<script>
export default {
name:'News',
data(){
return{
messageList:[
{
id:'001',title:'消息001'},
{
id:'002',title:'消息002'},
{
id:'003',title:'消息003'}
]
}
}
}
</script>
src/pages/Detail.vue:
<template>
<ul>
<li>消息编号:{
{
$route.params.id}}</li>
<li>消息标题:{
{
$route.params.title}}</li>
</ul>
</template>
<script>
export default {
name:'Detail'
}
</script>
总结:
1、配置路由,声明接收params参数:
{
path:'/home',
component:Home,
children:[
{
path:'news',
component:News
},
{
component:Message,
children:[
{
name:'xiangqing',
path:'detail/:id/:title', //使用占位符声明接收params参数
component:Detail
}
]
}
]
}
2、传递参数:
<!-- 跳转并携带params参数,to的字符串写法 -->
<router-link :to="/home/message/detail/666/你好">跳转</router-link>
<!-- 跳转并携带params参数,to的对象写法 -->
<router-link
:to="{
name:'xiangqing',
params:{
id:666,
title:'你好'
}
}"
>跳转</router-link>
特别注意:路由携带params参数时,若使用to的对象写法,则不能使用path配置项,必须使用name配置!
3、接收参数:
$route.params.id
$route.params.title
