vue路由props传递参数

props分为三种形式

• props为对象
• props为布尔值，这种只能接收params动态路由的参数
• props为函数，可以接收query和params参数(推荐)

import Vue from 'vue'
import VueRouter from 'vue-router'
import HomeView from '../views/HomeView.vue'

Vue.use(VueRouter)

const routes = [
  {
    path: '/',
    name: 'home',
    component: HomeView
  },
  {
    path: '/about',
    name: 'about',
    props: {
      name: "张三",
      age: 20,
      addr:'河南省信阳市商城县李集乡新庄村'
    },
    component: () => import(/* webpackChunkName: "about" */ '../views/AboutView.vue')
  },
  {
    path: '/detail/:id/:title',
    name: 'detail',
    // props是个布尔值
    // props:true,
    props($route){
      return {
        id:$route.params.id,
        title:$route.params.title
      }
    },
    component: () => import(/* webpackChunkName: "detail" */ '../views/Detail.vue')
  },
  {
    path: '/mine',
    name: 'mine',
    props($route){
      return {
        id:$route.query.id,
        title:$route.query.title
      }
    },
    component: () => import(/* webpackChunkName: "detail" */ '../views/Mine.vue')
  }
]

const router = new VueRouter({
  mode: 'hash',
  base: process.env.BASE_URL,
  routes
})

export default router

about(props为对象的时候)

 <template>
  <div class="about">
    <h1>This is an about page</h1>
    <ul>
      <li>{{name}}</li>
      <li>{{age}}</li>
      <li>{{addr}}</li>
    </ul>
    <router-link :to="{
      name:'detail',
      params:{
        id: 1,
        title:'张三'
      }
    }">
      跳转detail页面
    </router-link>
    <router-link :to="{
      path:'/mine',
      query:{
        id: 1,
        title:'张三'
      }
    }">
      跳转mine页面
    </router-link> 
  </div>
</template>
<script>
export default {
  props: {
    name: {
      type: String,
    },
    age: {
      type: Number,
    },
    addr: {
      type: String,
    },
  },
}
</script>

detai(props为布尔值，注意这种只能接收params参数)

<template>
  <div class="detail">
   <h1>详情页面</h1>
   <ul>
    <li>id: {{id}}</li>
    <li>title: {{title}}</li>
   </ul>
  </div>
</template>

<script>
// @ is an alias to /src

export default {
  name: 'Detail',
  components: {},
  props: {
    id: {
      type: [Number,String],
    },
    title: {
      type: String,
    },
  }
}
</script>

mine页面(props为函数的时候，可以接收query参数和params参数)

<template>
  <div class="mine">
   <h1>我的页面</h1>
    <ul>
      <li>id: {{id}}</li>
      <li>title: {{title}}</li>
   </ul>
  </div>
</template>

<script>
// @ is an alias to /src

export default {
  name: 'Mine',
  components: {},
  props: {
    id: {
      type: [Number,String],
    },
    title: {
      type: String,
    },
  }
}
</script>
