import Vue from 'vue'
import App from './App.vue'
import router from './router'
Vue.config.productionTip = false
new Vue({
router,
render: h => h(App)
}).$mount('#app')
二、基本使用（代码后赋）
以下例子展现路由的基本使用
css样式已经写好了，直接实现路由效果
展示效果
首先学习的效果
代码（看对应的代码段）
app.vue代码，此代码含有样式
<template>
<div id="root">
<div class="main">
<div class="header">
<h1>路由的演示</h1>
<button @click="back">后退</button>
</div>
</div>
<div class="main">
<div class="left">
<ul>
<li><router-link to="/about" active-class="hover">公司简介</router-link></li>
<li><router-link to="/contaactus" active-class="hover">联系方式</router-link></li>
<li><router-link to="/persons" active-class="hover">公司人员</router-link></li>
</ul>
</div>
<div class="right">
<router-view></router-view>
</div>
<div style="clear: both;"></div>
</div>
</div>
</template>
<script>
export default {
name:'App',
methods: {
back(){
this.$router.back()
}
},
components:{
},
}
</script>
<style>
.c{
clear: both;
}
*{
margin: 0px;
padding: 0px;
}
li{
list-style: none;
}
a{text-decoration: none;}
.main{width: 800px;margin: auto;}
.header{box-sizing: border-box;padding: 20px;border:1px solid #666;}
.left{
height: 500px;
border: 1px solid #666;
width: 200px;
float: left;
}
.left li{
height: 50px;
line-height: 50px;
text-align: center;
border-bottom: 1px solid #666;
width: 100%;
}
.left li a{
color: #333;display: block;
}
.left li a.hover{
background: blue;color: #fff;
}
.right{float: right;
border:1px solid #61DAFB;
width: 590px;
height: 500px;
}
.nav li{
float: left;
}
.nav li a{
width: 150px;
text-align: center;
height: 40px;line-height: 40px;
text-align: center;
border:1px solid #000000;
display: block;
}
.nav li a.hover{
background: #0000FF;color: #fff;
}
</style>
三个路由组件的代码
about
<template>
<div>
<!-- <div class="left"> -->
<ul class="nav">
<li><router-link to="/about/year" active-class="hover">创建年份</router-link></li>
<li><router-link to="/about/people" active-class="hover">创建人</router-link></li>
</ul>
<!-- </div> -->
<keep-alive include="People">
<router-view class="c"></router-view>
</keep-alive>
</div>
</template>
<script>
export default {
name: 'About',
data() {
return {
};
},
mounted() {
},
methods: {
},
};
</script>
<style scoped>
</style>
ContaactUs
<template>
<div>
联系方式
</div>
</template>
<script>
export default {
name: 'ContaactUs',
data() {
return {
};
},
mounted() {
},
methods: {
},
};
</script>
<style scoped>
</style>
persons
<template>
<div>
<ul >
<li v-for="item in persons" :key="item.id">
<router-link :to="`/persons/show/${item.id}/${item.realname}`">姓名：{{item.realname}}</router-link>
<!-- <router-link :to="`/persons/show/?id=${item.id}&realname=${item.realname}`">姓名：{{item.realname}}</router-link> -->
<!-- <router-link :to="{name:'show',query:{id:item.id,realname:item.realname}}">姓名：{{item.realname}}</router-link> -->
<button @click="push(item)">点击跳转</button>
</li>
</ul>
<hr>
<router-view></router-view>
</div>
</template>
<script>
export default {
name:'Persons',
data(){
return{
persons:[
{id:1,realname:'张三'},
{id:2,realname:'李四'},
{id:3,realname:'王五'},
{id:4,realname:'赵六'}
]
}
},
methods: {
push(item){
this.$router.push(`/persons/show/${item.id}/${item.realname}`)
},
},
}
</script>
<style>
</style>
router
import Vue from 'vue'
import VueRouter from 'vue-router'
Vue.use(VueRouter)
import About from '../pages/About'
import ContaactUs from '../pages/ContaactUs'
import Persons from '../pages/Persons'
// import Show from '../pages/Show'
// import Profile from '../pages/Profile'
// import People from '../pages/People'
const routes = [
{
path:'/about',
component:About,
children:[
// {name:'profile',path:'/about/year',component:Profile,meta:{isAuth:true}},
// {name:'people',path:'/about/people',component:People,meta:{isAuth:true}},
// {
// path:'/about',
// redirect:'/about/year'
// },
]},
{
path:'/contaactus',
component:ContaactUs
},
{
path:'/persons',
component:Persons,
// children:[
// {
// path:'show/:id/:realname',component:Show,props:true
// // name:'show', path:'show',component:Show
// }
// ]
},
{
path:'/',
redirect:'/about'
},
]
const router = new VueRouter({
mode:'history',
routes
})
// router.beforeEach((to,from,next)=>{
// if(to.name=="people" || to.name=="profile"){
// if(localStorage.getItem("token")=="123"){
// next();
// }
// }else{
// next();
// }
// })
// router.beforeEach((to,from,next)=>{
// if(to.meta.isAuth){
// if(localStorage.getItem("token")=="123"){
// next();
// }
// }else{
// next();
// }
// })
export default router
以上就能实现，视屏上的的切换的路由效果，如果有不懂的，私信问我，源码私聊免费提供
三、嵌套路由
1.布局逻辑
嵌套路由在，最开始的路由下，加入路由
在about路由组件中
再次创建两个路由组件，点击是，获得相对应的内容，实现路由效果
2.效果展示
3.代码
about
<template>
<div>
<!-- <div class="left"> -->
<ul class="nav">
<li><router-link to="/about/year" active-class="hover">创建年份</router-link></li>
<li><router-link to="/about/people" active-class="hover">创建人</router-link></li>
</ul>
<!-- </div> -->
<keep-alive include="People">
<router-view class="c"></router-view>
</keep-alive>
</div>
</template>
<script>
export default {
name: 'About',
data() {
return {
};
},
mounted() {
},
methods: {
},
};
</script>
<style scoped>
</style>
两个路由组件
Profile
<template>
<div>
2002 08-20
</div>
</template>
<script>
export default {
name:'Profile',
// beforeDestroy () {
// console.log('已销毁');
// },
}
</script>
<style>
</style>
People
<template>
<div>
<span>傅小余</span> <input type="text">
</div>
### 最后
**小编的一位同事在校期间连续三年参加ACM-ICPC竞赛。从参赛开始，原计划每天刷一道算法题，实际上每天有时候不止一题，一年最终完成了 600+：**
**凭借三年刷题经验，他在校招中很快拿到了各大公司的offer。**
**入职前，他把他的刷题经验总结成1121页PDF书籍，作为礼物赠送给他的学弟学妹，希望同学们都能在最短时间内掌握校招常见的算法及解题思路。**
**整本书，我仔细看了一遍，作者非常细心地将常见核心算法题和汇总题拆分为4个章节。**
**而对于有时间的同学，作者还给出了他结合众多数据结构算法书籍，挑选出的一千多道题的解题思路和方法，以供有需要的同学慢慢研究。**
