Angular2，相对导航(向后两级../../) [英] Angular2, relative navigation (two levels back ../../)

问题描述

我的应用程序中有一个后退按钮，它可以向后导航一些级别.如果是一级

I have a back button in my application, which navigates relatively some levels back. In case of one level

this.router.navigate(['..'], { relativeTo: this.route });

它运行完美(生成的路由URL:http://localhost:3000/three/two/one).在两级后退的情况下.导航

it works perfectly (resulted route url:http://localhost:3000/three/two/one). In case of two level back rel. navigation

this.router.navigate(['..', '..'], { relativeTo: this.route });

router向后导航两个级别，但，生成的路由URL现在看起来像http://localhost:3000/three/two/(斜杠，这是不正确的).

router navigates two levels back, BUT the resulted route url looks now like http://localhost:3000/three/two/(tailing slash, which is not correct).

我做错什么了吗，或者可能是个错误?

Am I doing something wrong or could it be a bug?

推荐答案

在两个级别以下的情况下，请使用以下命令:

In case of two levels down use this:

this.router.navigate(['../../'], { relativeTo: this.route });
