本例基于 路由的基本使用、嵌套路由的实现。

项目目录如下：

• 一般组件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>

<style>

</style>

• 路由组件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>
      <div>
        <router-view></router-view>
      </div>
    </div>
  </div>
</template>

<script>
export default {
    name:'Home'
}
</script>

<style>

</style>

• 路由组件pages/About.vue

<template>
  <h2>我是About的内容</h2>
</template>

<script>
export default {
    name:'About'
}
</script>

<style>

</style>

• 路由组件pages/News.vue

<template>
    <ul>
        <li>news001</li>
        <li>news002</li>
        <li>news003</li>
    </ul>
</template>

<script>
export default {
    name:"News"
}
</script>

<style>

</style>

• 路由组件pages/Message.vue

<template>
    <div>
        <ul>
            <li v-for="message in messageList" :key="message.id">
                <!-- <router-link :to="`/home/message/detail?id=${message.id}&title=${message.title}`">{{message.title}}</router-link> -->
                <router-link :to="{
                    path:'/home/message/detail',
                    query:{
                        id:message.id,
                        title:message.title
                    }
                }">
                    {{message.title}}
                </router-link>
            </li>
        </ul>
        <hr>
        <router-view></router-view>
    </div>
</template>

<script>
export default {
    name:"Message",
    data(){
        return {
            messageList:[
                {id:"001",title:"消息01"},
                {id:"002",title:"消息02"},
                {id:"003",title:"消息03"},
            ]
        }
    }
}
</script>

<style>

</style>

• 路由组件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>

<style>

</style>

• 创建路由器，配置路由规则，router/index.js

import VueRouter from "vue-router";
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";

export default new VueRouter({
    routes:[
        {
            path:"/about",
            component:About
        },
        {
            path:"/home",
            component:Home,
            children:[
                {
                    path:"message",
                    component:Message,
                    children:[
                        {
                            path:"detail",
                            component:Detail
                        }
                    ]
                },
                {
                    path:"news",
                    component:News
                }
            ]
        }
    ]
})

• 组件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">
          <router-link to="/about" active-class="active" class="list-group-item">About</router-link>
          <router-link to="/home" active-class="active" class="list-group-item">Home</router-link>
        </div>
      </div>
      <div class="col-xs-6">
        <div class="panel">
          <div class="panel-body">
            <router-view></router-view>
          </div>
        </div>
      </div>
    </div>
  </div>
</template>

<script>
import Banner from "./components/Banner.vue";

export default {
  name: 'App',
  components:{
    Banner
  }
}
</script>

• 入口文件main.js

import Vue from 'vue'
import App from './App.vue'
import VueRouter from "vue-router";

import router from "./router/index";

Vue.config.productionTip = false;

Vue.use(VueRouter);

new Vue({
  render: h => h(App),
  router:router
}).$mount('#app')

启动应用，测试效果。

Message组件发送query参数

路由的query参数传递发生在路由组件Message.vue、路由组件Detail.vue之间，query参数通过to属性传递，有以下两种方式：

1. 字符串写法

<router-link :to="`/home/message/detail?id=${message.id}&title=${message.title}`">{{message.title}}</router-link>

2. 对象写法

<router-link :to="{
    path:'/home/message/detail',
    query:{
        id:message.id,
        title:message.title
    }
}">
    {{message.title}}
</router-link>

Detail组件接收query参数

<ul>
    <li>消息编号：{{$route.query.id}}</li>
    <li>消息标题：{{$route.query.title}}</li>
</ul>
