实现效果:
?首先创建五个vue界面
1.home.vue页面
<template>
<div id="home-wrapper">
<h1>{{ name }}</h1>
<nav>
<!-- 二级路由的出口 在一级路由的界面里面 -->
<router-link to="/one">one</router-link>
<router-link :to="{ name: 'Two' }">two</router-link>
<router-link :to="threeObj">three</router-link>
<!-- 编程式 导航/路由 -->
<button @click="fourBtn">four</button>
</nav>
<router-view></router-view>
</div>
</template>
<script>
export default {
data() {
return {
name: "首页",
threeObj: {
name: "Three",
},
};
},
methods: {
fourBtn() {
var userId = 6789;
this.$router.push({
path: `four/${userId}`,
});
},
},
};
</script>
<style lang="less" scoped>
#home-wrapper{
nav{
display: flex;
a{
flex: 1;
background-color: antiquewhite;
height: 50px;
line-height: 50px;
}
}
}
</style>2.one.vue界面
<template>
<div>
<h1>{{name}}</h1>
<ul>
<li>
<router-link to="/levl31">web</router-link>
</li>
<li>
<router-link :to="{name:'name32'}">后端</router-link>
</li>
<li>
<!-- 使用命名路由 在多级路由里面 比较方便 -->
<router-link :to="{name:'name33'}">AI</router-link>
</li>
<li>
<router-link to="/one/levl34">UI</router-link>
</li>
<li>
<router-link :to="{name:'name35'}">三级路由-4</router-link>
</li>
</ul>
<!-- 三级路由 出门在二级路由的界面 -->
<router-view></router-view>
</div>
</template>
<script>
export default {
name:'One',
data() {
return {
name: "第一页"
}
},
}
</script>
<style lang="less" scoped>
ul{
list-style: none;
display: flex;
width: 100%;
margin-left: -40px;
}
li{
flex: 1;
background-color: orange;
height: 50px;
line-height: 50px;
}
</style>?3.two.vue页面以及验证码实现
实现效果图:
?
<template>
<div>
<h1>{{ name }}</h1>
<button @click="changeCode">验证码</button>
<img :src="imgCodeUrl" alt="">
</div>
</template>
<script>
export default {
// 组件的别名 在vue调试的时候方便查看
name: "Two_zh",
data() {
return {
name: "第二页",
imgCodeUrl:""
};
},
methods: {
// 获取验证码
changeCode() {
// /api 是在vue.config.js 里面代理配置
const url = "api/v1/captchas";
// const url = "https://elm.cangdu.org/v1/captchas";
this.axios
.post(url, {})
.then((res) => {
this.imgCodeUrl =res.data.code
console.log("验证码接口:",res);
})
.catch((e) => {
console.log("错误:", e);
});
},
},
};
</script>
<style lang="less" scoped>
</style>4. three.vue页面
<template>
<div>
<h1>{{name}}</h1>
</div>
</template>
<script>
export default {
name:'three',
data() {
return {
name: "第三页"
}
},
}
</script>
<style lang="less" scoped>
</style>5.four.vue页面
<template>
<div>
<h1>{{name}}</h1>
</div>
</template>
<script>
export default {
name:'Four',
data() {
return {
name: "第四页"
}
},
created() {
console.log("第四页 created:",this.$route)
},
}
</script>
<style lang="less" scoped>
</style>然后配置路由:
import Vue from 'vue'
import VueRouter from 'vue-router'
import Home2 from '@/views/day/home.vue'
Vue.use(VueRouter)
const routes = [
{
path: "/",
name: 'home2',
component: Home2,
redirect: "/one",
children: [
{
path: "/one",
name: 'One',
component: () => import("@/views/day/one.vue"),
children: [
{
path: '/levl31',
// h creacteElemet 的意思 创建 虚拟Dom/标签 Vnode
// 第一个参数是 标签名 扩展的话 自己的写的组件 也是标签名
// 第二个参数是 可选的 标签的属性配置
// 第三个参数是 标签的内容
component: {
render(h) {
return h("h1", "前端")
}
},
},
{
// /默认代表根目录 #/levl31
// 不带斜杠 会自己拼接 #/one/levl32
// 使用的时候统一用命名路由
path: "levl32",
name: "name32",
component: {
render(h) {
return h("h1", "后端")
}
},
},
{
path:"/one?levl33",
name:"name33",
component:{
render(h) {
return h("h1", "人工智能")
}
}
},
{
path:"/one/levl34",
name:"name34",
component:{
render(h) {
return h("h1","就是个美工吗")
}
}
},
// 三 四级路由
{
path:"level35",
name:"name35",
component:()=>import("@/views/Home.vue"),
// 四级路由
children:[
{
path:"boy",
name:"Boy",
component:()=>import("@/views/boy.vue")
},
{
path:"girl",
name:"Girl",
component:()=>import("@/views/girl.vue")
}
]
}
]
},
{
path: "/two",
name: 'Two',
component: () => import("@/views/day/two.vue")
},
{
path: "/three",
name: 'Three',
component: () => import("@/views/day/three.vue")
},
{
// 可选参数 \d 数字 字符串就匹配不上
path: "four/:id(\\d*)?",
name: 'Four',
component: () => import("@/views/day/four.vue")
},
]
}
]
const router = new VueRouter({
routes
})
export default router
