Vue74 路由的props配置
笔记
作用：让路由组件更方便的收到参数
{name:'xiangqing',path:'detail/:id',component:Detail,//第一种写法：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Detail组件// props:{a:900}//第二种写法：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Detail组件// props:true//第三种写法：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Detail组件props(route){return {id:route.query.id,title:route.query.title}}
}
