角2：如何确定与参数活动路线？ [英] Angular 2: How to determine active route with parameters?

问题描述

我读过<一个href=\"http://stackoverflow.com/questions/34323480/in-angular-2-how-do-you-determine-the-active-route\">this有关如何确定活动路线，但仍然是我不清楚如何确定与PARAMATERS活跃的路由？问题

I've read this question about how to determine the active route, but still it's not clear to me how to determine an active route with paramaters?

现在我做的是这样的：

<a [routerLink]="['/Profile/Feed', {username: username}]"
   [ngClass]="{active: getLinkStyle('/profile/john_doe/feed')}">
   Feed for {{username}}
</a>

和我的组件中：

getLinkStyle(path:string):boolean {
  console.log(this._location.path()); // logs: '/profile/john_doe/feed'
  return this._location.path() === path;
}

和这将工作，因为我传递的用户名作为一个字符串。有没有什么办法与传递正确的参数？要做到这一点

And this will work because I'm passing the username as a string. Is there any way to do this with passing the correct parameter??

推荐答案

只要勾选自动定义的路由器链路主动类 A 元素。

Just check the auto-defined router-link-active class to a element.
