Vue - 路由组件传参（props配置）

作用：让路由组件更方便的收到参数

布尔模式

props值为布尔值，布尔值为true，则把路由收到的所有params参数通过props传给Info组件

const routes = [
  {
    path: '/about',
    name: 'About',
    component: () => import(/* webpackChunkName: "about" */ '../views/About.vue'),
    children:[
      {
        path:'person',
        name:'Person',
        component: () => import('../views/Person'),
        children:[
          {
            name:'Info',
            path:'info',
            component: () => import('../views/Info'),
            props:true,
          }
        ]
      }
    ]
  }
]

对象模式

props值为对象，该对象中所有的key-value的组合最终都会通过props传给Info组件

const routes = [
  {
    path: '/about',
    name: 'About',
    component: () => import(/* webpackChunkName: "about" */ '../views/About.vue'),
    children:[
      {
        path:'person',
        name:'Person',
        component: () => import('../views/Person'),
        children:[
          {
            name:'Info',
            path:'info',
            component: () => import('../views/Info'),
            props:{name:'张三',age:18},
          }
        ]
      }
    ]
  }
]

函数模式

props值为函数，该函数返回的对象中每一组key-value都会通过props传给Info组件

const routes = [
  {
    path: '/',
    name: 'Home',
    component: Home
  },
  {
    path: '/about',
    name: 'About',
    // route level code-splitting
    // this generates a separate chunk (about.[hash].js) for this route
    // which is lazy-loaded when the route is visited.
    component: () => import(/* webpackChunkName: "about" */ '../views/About.vue'),
    children:[
      {
        path:'person',
        name:'Person',
        component: () => import('../views/Person'),
        children:[
          {
            name:'Info',
            path:'info',
            component: () => import('../views/Info'),
            props(route){
              return {
                name:route.query.name,
                age:route.query.age
              }
            },
          }
        ]
      }
    ]
  }
]

接收参数

<template>
  <div>
    <p>姓名：{{name}}</p>
    <p>年龄：{{age}}</p>
  </div>
</template>

<script>
export default {
  name: "Info",
  props:['name','age']
}
</script>
