Angular 2 @ angular/router 3.0.0-alpha.7-访问多个参数 [英] Angular 2 @angular/router 3.0.0-alpha.7 - Accessing Multiple Parameters

问题描述

我正在尝试最近发布的Angular 2中的新路由器，即Angular 2 @ angular/router 3.0.0-alpha.7

I am just trying the new router in Angular 2 announced recently i.e. Angular 2 @angular/router 3.0.0-alpha.7

我知道在新路由器中，我们可以使用以下代码访问路由参数:

I know that in new router we can access route parameters using below code:

this.activatedRoute.params
            .map(params => params['id'])
            .subscribe((id) => {

             //use param id

             });

任何人都可以指导我们如何处理路线中具有多个参数的情况吗?

Can anyone please guide how do we handle the case in which we have multiple multiple parameters in our route?

我的意思是我们如何从route中检索多个参数的值.

I mean how do we retrieve the values of multiple parameters from route.

推荐答案

一种方法是使用解构是这样的:

One way you could do it is using Parameter handling and Destructuring like this:

this.activatedRoute.params
  .map(params => [params['id'], params['p2'], params['p3']]) <== pass desired array
  .subscribe(([id, p2, p3]) => { <== destructuring params
      //use param id, p2 or p3
   });

或者您可以写一些简单的东西:

Or you can write a bit simple:

this.activatedRoute.params
  .subscribe(({id, p2, p3}) => { <== destructuring params
      //use param id, p2 or p3
   });
